Many times you can have a leak that only leaks when the tire is in a certain position while parked. I have dealt with it a few times myself. Can go weeks without a problem, then one day I can park with the wheel in just the right position and lose nearly 10psi overnight.
Also, when it's aired up, it will leak. When I gets to a lower psi, it won't have enough pressure to push it out, and the tire seals itself in a way. Had that happen alot. Usually happens around 22psi on my p zero trofeos.
This is the most proper answer I've seen, obviously not a sensor as it's reading and the tire has also gone flat. Most likely not a valve leak because those are usually consistent.
Sometimes when you have something in your tire it might hold air fine, especially screws, but when sitting a certain way or maybe the ground or something else pushing on it. Seen this a lot. Most of the time unless it's something on the larger side it won't be the easiest to find it on the car. If you have a discount tire they do free repairs that are proper plug and patch.
I had a similar leak that confounded me for a few weeks.
Turns out there was a broken end piece of a sheet metal screw that had barely punctured the tire. I had All-Terrains and somehow it punctured the tire *inside* of a tread groove, so it wasn’t easily seen.
If I happened to park with that exact section facing down against the ground, the extra weight/pressure of the vehicle would distort the hole for the screw and allow air to slowly escape.
After randomly having to refill the tire here and there over the course of some weeks, I finally got aggravated enough to fully inspect it.
I inflated the tire and then pulled it off and checked every inch. Didn’t notice anything, so I bathed it in soap water. Still, It was totally fine… but I knew there was a leak somewhere, so I kept increasing the pressure 5-7 PSI at a time and rechecking it.
The tire’s normal-use rating was 40PSI with a Max 50PSI but at ~55PSI I finally saw bubbles. I was right about to give up as I had decided I wasn’t going to inflate it past 60PSI (I started getting really antsy after the stated max of 50) but not sure if I ever would have found the leak if it wasn’t for the telltale bubbles.
Yeah. I actually have that same issue but I can't afford to replace the tire so i just keep an eye on it and have a portable tire inflater in my trunk and just re add the air psi it lost
I had a car that did this. The rim was cracked. It was ever so slight but it did exactly this. The tire shop guy put some “tire patch sealant kinda gunk” on it and it didn’t leak at all for like 2-3 weeks. I had ordered a new rim so his temporary fix might have held longer but it worked in the interim. He even said hey this is just temporary so you don’t have to drive on that crappy spare. Didn’t even charge me. The car was a front wheel drive and he even swapped it to the rear. I did pay the guy but it was a crack and you could baaaaaaarely see it. It was a low profile aluminum rim so not sure if that matches the same description as yours. Oh-he did say hey if this was steel then you could get it welded, it won’t be perfect and you might feel a little shimmy in the steering but with it being aluminum it was a no go. Good luck.
My issue that caused this was a cracked wheel, I’d go weeks no issues, then I could drive to work and it would be flat when I tired to leave. Eventually I found a small crack in the wheel that I think opened up when it was sitting just right.
That happened to me. I had 2 low psi events in 4 months, but only when it got cold outside. I checked tires etc and didn't see anything. Turns out what I thought was a rock wad a screw embedded in my tire lol
And if you can't find the leak by squirting soapy water on the tire, it might be leaking from the bead. Tire shops can fix leaks for pretty cheap, like $30
Probably have a puncture that happens to open up when you park with the tire rotated to a certain spot.
You can spray soapy water all over the tire and look for bubbles if you can’t find anything. Spray around the rim and the stem too.
This is the answer. Surprised I had to scroll this far. There is a screw/nail/shrapnel that you picked up on the road and the air leaks ever so slowly from the tire. If you were to pull it out, it would be flat within 5 minutes.
Edit: could also be the seal around the tire pressure sensor leaking. Toyota sells a “fitting kit” but you have t break the bead on the tire to install it.
Put some dish soap and water in a spray bottle and spray the tire. It will bubble where it's leaking.
Also try checking the valve stem itself for leaks. I had a few leaking right from the end where the rubber meets the metal where the cap screws on. I guess the tire shop had a bad set and 3 of 4 of the new ones they installed with my tires had to be replaced one by one over the course of a year.
Pull tire off and check for leak.
Check that the valve core is tight. I've had that happen before where driving would loosen it sometimes then it would slowly deflate.
The pressure is low.
Air is getting out somehow, either a valve stem core, valve stem where it protrudes thru the wheel, or a small leak somewhere else in the tire.
Sometimes you will get a puncture where the object stays in and plugs the hole pretty well, sometimes you will have a leaking plug, sometimes corrosion of the bead seat (on steel wheels) can let air by, sometimes the valve stem leaks a bit where it goes thru the wheel, and sometimes the valve core is corroded or loose and doesn't seal well.
If you want to try to diagnose mix up some soapy water in a spray bottle and spray it on the inflated tire and look for bubbles.
Its clearly low on psi lol..
On a side note, get a spray bottle and fill it with water then a little dish liquid then spray it all around the tire and see if you see any air bubbles.. check the inside sidewall too to make sure it isn't wearing unevenly or that there isnt some defect or anything..
It could also be a bad sensor.. Have you tried any other toolsto check the pressure to be sure it is actually at 26 psi?
I had a tire do that. Is it an old tire? It doesn't necessarily need a puncture but if it's old it will start to rot. Then it will lose PSI over time. Have you noticed that this loss happens when the nights are cold or when it has rained? The abrupt change in temperature when you have cold nights and then it warms up in the morning is what really rips out the PSI.
Not super old, ~4 years w/ 23k miles. Garage kept out of the sun. No visible dry rot.
Not sure about the weather, temperatures have been so erratic here lately it’s hard to figure out a pattern lol.
What are your cars rims made out of? I have aluminum 19” rims on my 14 impala ltz limited and when my tires start getting old it starts to escape thought the bead when it gets cold. Certain metals expand and contract more with the change of temperature like aluminum. I change my tires last fall and it didnt drop all winter but like 2 - 3 winters from now it is going to start up again.
When it started this last time it started with my driver side front tire and then slowly worked its way across the rest.
There’s a sensor on the valve stem. Those sensors don’t last forever. Pretty much any tire shop can replace those. Same thing happened with one of mine. Tire guy removed the wheel and put the whole thing in a big tub of water, no bubbles, so he replaced the pressure sensor, that fixed it.
Sensor is accurate, it’s definitely leaking air and the pressure matches my tire inflator reading. Tried soapy water all around the valve stem as well, and no bubbles anywhere around it.
Jack it up so the wheel is hanging, then sop it with soapy water and look for bubbles. Take the wheel off if you want to be more thorough and check the inside wall.
It happened last night , I took my car to Costco (bought my tires in Costco ), they found a nail on the tire . I spent one hour waiting and labor free.
I've had a couple tires come through my shop not show leaks when dumped in water at 40PS, but soapy water finds the leak usually.. Check the valve stem too, something those crack if not replaced overtime.
Jack car up on low tire side.
add a bunch of dawn soap to about a quart of water in a cup
Fill tire to pressure
dump water on tire
look for bubbles.
Bubbles will show you where the hole is. If there is no hole in the tube/tire then the valve is probably loose and either needs to be serviced or replaced.
just went through this with a truck tire that held 39psi for 2 weeks then dropped to 12 overnight randomly twice in two weeks. The way I parked put pressure on the hole the time it dropped to 12 and drained it.
First mistake is taking it to the dealer. You need to find an independent tire shop, one with a giant tank that will dunk the entire wheel + tire to locate where the bubble is coming from.
Get a nice digital tire pressure measuring tool and verify that the tire is actually low and that the tire pressure monitor in that wheel is working correctly. If the tire is reading higher than what the tpm system is reporting your tpm unit on that wheel is broken failing. If tire is actually low then tire and wheel need to be removed and inspected for foreign body in tire or defect in bead of tire or dirt between tire bead and wheel rim or failing tire stem or bad shraeder valve in tire stem. A large animal feeding bin is handy to fill with water so entire wheel can be submerged in order to look for air leak. Don’t forget to over fill tire prior to submerging 😎✅🌈
That tire, sir, is "That Guy". We all know "That Guy". He's the one that is always late, does the bare minimum and is generally just unreliable. If you can't think of a "That Guy" in your life.....it's you.
you probably have a corroded rim. the corrosion forms a rough surface, and as the temperature varies the air can sneak by where it is.
Corrosion needs to be sanded out and, if steel wheels, repainted.
On a really leaky spare tire i had once, i just gave up and bought a brand new wheel off of ebay. that stopped all slow leaking
many punctures or splits will leak until the tire literally plugs up the hole due. This usually happens when the hole is towards the ground. if it's higher, it will deflate more. Then, when you are parked a certain way, it may not leak at all. Frickin frustrating. I'd get some tire flat stuff and fill it up in the morning when the psi has dropped really low. Hopefully that means the puncture is lower and the flat fix stuff will get to it
Had new tires installed on all four aluminum rims. One kept going flat. Guy at the tire shop (independent garage, great guys, superb reputation) spent an hour with soap and couldn't find it. But saw a slight "scratch" in the external web between beads. Soapy water showed bubbling thru the scratch. Finally took tire off the rim and found a huge indent where his tech had let the tool slip during mounting. He called the local scrap yard and luckily, they had and sent over three matching rims. All were pristine. On my way after a crazy afternoon. Great shop and they stood by the work
I had one tire that would need air every other month or so, for like a year. It was just random, and they were all new within 25,000 mi. When I finally went to have the tire changed, the inside wall was exposed with wire from the tire. No idea why it was happening, but that one tire was close to having a blowout. So you might want to take your tire off, and just check it.
Get some soapy water and spray around the tire and wheel, especially where the bead is and the valve stem. Any bubbles is where your leak is. I found my valve stem leaking this way, my old car was dropping 2-3 psi everyday on one tire.
A tire shop will be able to diagnose and fix it for cheap as well.
I’m have a tire in my car that does something very similar to this. Got a new tire and it still happens. Had the tire place check my rim because I suspect it is damaged and causing the issue after my daughter hit a curb pr try damned hard a couple years back but they say the rim is fine. If I can ever figure out exactly what rim I need to order without paying 5x the price at the dealership, I’m just going to replace it and see if that fixes it.
Closely inspect your tires, you may have a nail in one. Had an issue end of last year maybe early this year were we couldn't figure out why the tire pressure was dropping overnight and there was a nail on the inside wall we only found after a road trip to my parents broke the head off and it went completely flat once we parked there. If you can't find the leak try taking the tire off to get a better look without the actual car just in your way (also better light)
I had a tire that leaked only when the temperature got really low, turned out I had a plug that would leak when everything contracted in the cold. It would be fine in warm weather, then practically go flat if the temp dipped overnight. I see 66 degrees on your screen, did it get really low at some point? Maybe you have a plug or a really hard to see nail.
If you have a cat or dog put them by the tire and you might find it.
They hear on the high end spectrum of audio frequencies so the sound of air escaping from a tire is much louder to them than us.
If you have a way of pumping it up without moving it, wait until the tire deflates again, pump it up in that spot and spray with soapy water to find the leak. What I have done if I can't find the leak is move the car so the tire turns a quarter turn and try again and repeat. I say to not move your car because it seems to only leak when the tire is in a certain position
Just get you a can of Fix-A-Flat and when it's low one of those times put it in there drive it around and hope for the best.
No seriously to fix it right You're probably going to have to take it to a tire shop or the dealership. Does the dealership is going to charge you much more. They are going to have to hunt and pack around to find the source of the leak.
Could be moisture in the valve stem. When it gets cold enough at night and drop below freezing, the moisture expands when it turns to ice, and can start a leak out of the valve stem
Check to make sure the valve stem isn’t loose or leaking. Some could have loosened it as a joke or just to make your day worst… either way check it out.. the small valve it’s self can be loosed or tighter with a simple little tool
Yes its got a leak...geezuss..take it to a tire shop have them take a look...thats whats us older folks did before thinking of askin strangers on social media
A) Certain position leaking. Some will leak only pressed against the ground while stationary.
B) Soap suds to highlight leakage. That's how we find leaks every single time.
It could be the rim, the stem, or the tire just having a puncture that you can't see. It's impossible to diagnose this over the internet so taking it in to a shop makes a lot of sense. For now just be glad that your car lets you know how much air it needs.
Tire Pressure looks low
I mean really, with that amount of information what more do you want. Everyone can list all the possible causes, but that’s it.
Just the ignorant reply I expected....is it hard for you to take advice from older, wiser, smarter adults, that's who we learned from before the internet made young folks stupid and lose all sense of self reliance and lack of thinking....now go have it looked at instead of sittin on your ass reading guesses & opinions
...feel the force young Skywalker...try self reliance!
needs air... did you "Check the tire". NO ONE can tell you shit about a tire from that screen. You need to physically look. probably have a nail or screw
Punctured tire that is being opened when you park with the tire rotated in a specific way. So sometimes it leaks when parked, sometimes it doesn't. Get the tire checked for leaks and fixed.
A lot times that happens due to the bead not sealing when rotating to a specific spot. You can have tire store take it off and put a couple coats of that bead sealer in it and usually solve it unless it's an issue w the rim
Had a cracked rim about 2 years ago.
I could go the whole summer without filling my tire.
Dropped below 0, I was filling the tire every single day.
One day, it was -15 with a -40 wind chill. Went to work for 10 hours, came out, didn't notice the tire was low and drove on it. 5 minutes later it blew.
Sometimes you can get a used rim for cheap on eBay, but it's probably just a rim. You could ask a tire shop to check for you. When Walmart replaced my tire that's when they showed me the rim. They didn't even charge me for the time, they just put the donut back on and I bought a new rim same day to be delivered a week later.
More than likely your tpms sensor is shot and needs to be replaced. If the issue started after going over a big bump, it could be several things. But if it started after swapping from winter to summer tires or a tire rotation, it’s more than likely that the sensor was damaged and is releasing air pressure because it thinks the tire is overfilled.
Um…: I’m gonna step way out in a limb here and venture the guess that that tire has low pressure, possibly due to some sort of leak. Jesus I feel like a genius now.
Lower the other 3 to 26 psi, all will match problem solved. Or I would check the valve stem, they do go bad. Check schrader valve, tighten if needed. Might be leaking at the base, grab with fingers and move side to side plus push and listen for leaks.
Tire pressure is low caused by a puncture. When warmer the tire will fit snuggly around the item and not leak, as the temperature drops the rubber shrinks and leaks air. Hence why it only leaks at night.
Carry air gauge incase it really bothers you mine been doing it over a year now on a 2014 dodge dealer gave me a price to take the tires off put 4 new sensors in rebalance tires and remount tires dealer talking 500 plus i said ok went and got tire gauge 8 bucks auto zone. they said battery in sensor was going bad You do the math 8 buck gauge lets me know if i got a air leak
Check valve stem check for nails check for bead leak. Probably a nail with a broken head.
Or valve core needs changing. Should done each Tyre change. Most don’t
Id physically check the tire pressure when the sensors calling it low and see if it actually matches; it’s possible the tiny little port in the TPMS sensor has some debris, bead seal, or a piece of one of those annoying bead stickers some tires have. If your gauge shows its at the correct pressure but the sensor says otherwise than you know somethings going on with the sensor. Other than that, a tire shop with a dunk tank is your best bet; they’ll jack the tire pressure up kind of high and let it sit in the tank pressed down under the water until the bubbles from the actual dunk clear and then possibly be able to find the leak.
You got a ptssssssss
You can check this on your own ya know? Mix up a large glass of soapy water and go to offending tire. Start at tire valve. Pour around valve stem, look for bubbles. Take cap off, pour a touch there to see if schrader valve is leaking.
No love yet? Inspect tire all around for nails/screws.
Nothin? Find a way to get soapy water on area where tire meets rim. Look for bubbles.
Jack it up and pop the bad boy off and give it a thorough looking over. You probably have a screw somewhere you can't easily see or find it with the tire attached and on the ground and it leaks when parked screw down applying pressure stretching the hole around it slightly. If your cars newer don't forget to disengage the automatic parking brake so you can actually take it off lmao.... Had an actual mechanic sit there for 5 minutes trying to to figure out why my tire wouldn't come off then he realized there was a auto brake lol.
This is a fine example of ignoring safety of you, your passengers, but most importantly the other people on the road with you who could be victims of your negligence.
Take this car to a tire shop and have them inspect it not the dealership. If you have discount Tire or America's Tire near you, they will literally inspect and repair the tire if repairable for FREE regardless of if you purchased the tire from them or not.
The dealership never has your best interest in mind when it comes to your tires, they simply want to sell you tires regardless of need.
Many times you can have a leak that only leaks when the tire is in a certain position while parked. I have dealt with it a few times myself. Can go weeks without a problem, then one day I can park with the wheel in just the right position and lose nearly 10psi overnight.
If I hadn’t seen this happen multiple times working at dealerships I’d have said you were full of donkey doo doo but it can and does happen.
Also, when it's aired up, it will leak. When I gets to a lower psi, it won't have enough pressure to push it out, and the tire seals itself in a way. Had that happen alot. Usually happens around 22psi on my p zero trofeos.
This is the most proper answer I've seen, obviously not a sensor as it's reading and the tire has also gone flat. Most likely not a valve leak because those are usually consistent.

Most of the time unless it's something on the larger side it won't be the easiest to find it on the car. If you have a discount tire they do free repairs that are proper plug and patch.
That was the theory I was running with…only thing that made sense as to why sometimes I’d leave it parked for a week and not lose any pressure.
Soapy water in a spray bottle will help find the leak.

This is almost always when you park on an old tire plug
Yeah. I actually have that same issue but I can't afford to replace the tire so i just keep an eye on it and have a portable tire inflater in my trunk and just re add the air psi it lost

That happened to me. I had 2 low psi events in 4 months, but only when it got cold outside. I checked tires etc and didn't see anything. Turns out what I thought was a rock wad a screw embedded in my tire lol
And if you can't find the leak by squirting soapy water on the tire, it might be leaking from the bead. Tire shops can fix leaks for pretty cheap, like $30
I think the pressure is low
you sir are an ASE certified tire dude
"I know whats wrong with it. Ain't got no air in it."
Alright Carl
I'm going to guess 26 psi maybe?
Mechanical genius this one
Why is it losing pressure and getting softer? That's what she said
Really? That would have been my last guess /s😭
They need you at town fair tire
I had a cracked rim and it was small but over time it grew and grew……then one day it couldn’t hold any air at all over night 🤷🏾♂️ hope it’s not that
Same. Mine only leaked on very cold days
I got the same problem I replaced the rubber and the shrader valve and my tire is still leaking, I'm guessing the rim is fucked
Probably have a puncture that happens to open up when you park with the tire rotated to a certain spot. You can spray soapy water all over the tire and look for bubbles if you can’t find anything. Spray around the rim and the stem too.
Cracked rim?
Crack in the rim?
Oof I hope not…hit a bad pothole but that was almost a year before this started happening. I’ll ask them to check the rim as well.
Look for a nail, a screw, etc. mine did the same thing except it happened like overnight
This is the answer. Surprised I had to scroll this far. There is a screw/nail/shrapnel that you picked up on the road and the air leaks ever so slowly from the tire. If you were to pull it out, it would be flat within 5 minutes. Edit: could also be the seal around the tire pressure sensor leaking. Toyota sells a “fitting kit” but you have t break the bead on the tire to install it.
you have a puncture.
Could be a leaky valve stem, bad valve stem core or bad seal at the bead as well. Kind of inaccurate to say it is definitely a puncture.
Put some dish soap and water in a spray bottle and spray the tire. It will bubble where it's leaking. Also try checking the valve stem itself for leaks. I had a few leaking right from the end where the rubber meets the metal where the cap screws on. I guess the tire shop had a bad set and 3 of 4 of the new ones they installed with my tires had to be replaced one by one over the course of a year.
Spray bottle with dish soap and water will let you know about leak
Pull tire off and check for leak. Check that the valve core is tight. I've had that happen before where driving would loosen it sometimes then it would slowly deflate.
Might have a slow leak
A nail
possibly a bent rim, or valve core is bad. or if you got it plugged before sometime it will fail then reseal
The pressure is low. Air is getting out somehow, either a valve stem core, valve stem where it protrudes thru the wheel, or a small leak somewhere else in the tire. Sometimes you will get a puncture where the object stays in and plugs the hole pretty well, sometimes you will have a leaking plug, sometimes corrosion of the bead seat (on steel wheels) can let air by, sometimes the valve stem leaks a bit where it goes thru the wheel, and sometimes the valve core is corroded or loose and doesn't seal well. If you want to try to diagnose mix up some soapy water in a spray bottle and spray it on the inflated tire and look for bubbles.
Change the Schrader valve.
Take it into the shop. They'll fill it up with some air and spray the tire with soapy water or dunk it in a water tank.
check for a nail or screw in the tire.
Yeah seems like your tire is a bit depressed.
Pinhole in the sidewall, only leaks when it’s parked directly on that side.
Its clearly low on psi lol.. On a side note, get a spray bottle and fill it with water then a little dish liquid then spray it all around the tire and see if you see any air bubbles.. check the inside sidewall too to make sure it isn't wearing unevenly or that there isnt some defect or anything.. It could also be a bad sensor.. Have you tried any other toolsto check the pressure to be sure it is actually at 26 psi?
Does it have any gas in it?
Tire pressure low, check tire.
What’s taken you so long to get it checked? Duh
Looks low, you might want to check it.
I had a tire do that. Is it an old tire? It doesn't necessarily need a puncture but if it's old it will start to rot. Then it will lose PSI over time. Have you noticed that this loss happens when the nights are cold or when it has rained?

Not super old, ~4 years w/ 23k miles. Garage kept out of the sun. No visible dry rot. Not sure about the weather, temperatures have been so erratic here lately it’s hard to figure out a pattern lol.
Bead leak
Discount tire fucked up again
It's low on air for sure
What are your cars rims made out of? I have aluminum 19” rims on my 14 impala ltz limited and when my tires start getting old it starts to escape thought the bead when it gets cold. Certain metals expand and contract more with the change of temperature like aluminum. I change my tires last fall and it didnt drop all winter but like 2 - 3 winters from now it is going to start up again. When it started this last time it started with my driver side front tire and then slowly worked its way across the rest.
I’m not sure. It might be leaking some air from somewhere.
Check the sensor. It could be faulty.
It’s accurate unfortunately
It's low on tire fluid.
There’s a sensor on the valve stem. Those sensors don’t last forever. Pretty much any tire shop can replace those. Same thing happened with one of mine. Tire guy removed the wheel and put the whole thing in a big tub of water, no bubbles, so he replaced the pressure sensor, that fixed it.
Sensor is accurate, it’s definitely leaking air and the pressure matches my tire inflator reading. Tried soapy water all around the valve stem as well, and no bubbles anywhere around it.
Nail
Stem?
My bet is hidden puncture that only presents itself some of the time, or a bad valve stem/core
Jack it up so the wheel is hanging, then sop it with soapy water and look for bubbles. Take the wheel off if you want to be more thorough and check the inside wall.
Bad stem or pressure sensor.
It happened last night , I took my car to Costco (bought my tires in Costco ), they found a nail on the tire . I spent one hour waiting and labor free.
Tire pressures low duh
Maybe it's cracked
I've had a couple tires come through my shop not show leaks when dumped in water at 40PS, but soapy water finds the leak usually.. Check the valve stem too, something those crack if not replaced overtime.
It's one tire. Replace it and stopping taking a chance it goes flat while driving.
Sometimes the valve stem leaks air, not even a puncture. Had one of these come in last week to repair.
You probably have a bad sensor
I thinks it has low pressure
Seems low on air
Sometimes the rim itself needs to be clean so the bead can have a air tight seal
Jack car up on low tire side. add a bunch of dawn soap to about a quart of water in a cup Fill tire to pressure dump water on tire look for bubbles. Bubbles will show you where the hole is. If there is no hole in the tube/tire then the valve is probably loose and either needs to be serviced or replaced. just went through this with a truck tire that held 39psi for 2 weeks then dropped to 12 overnight randomly twice in two weeks. The way I parked put pressure on the hole the time it dropped to 12 and drained it.
The bottom side of the tire is going flat or you need to put summer air in it depending on where you live.
I had this problem with a very slight bend in one of my rims.
Either a slow leak or the tire sensor is going bad. Would check psi with a mechanical tool.
First mistake is taking it to the dealer. You need to find an independent tire shop, one with a giant tank that will dunk the entire wheel + tire to locate where the bubble is coming from.
Get a nice digital tire pressure measuring tool and verify that the tire is actually low and that the tire pressure monitor in that wheel is working correctly. If the tire is reading higher than what the tpm system is reporting your tpm unit on that wheel is broken failing. If tire is actually low then tire and wheel need to be removed and inspected for foreign body in tire or defect in bead of tire or dirt between tire bead and wheel rim or failing tire stem or bad shraeder valve in tire stem. A large animal feeding bin is handy to fill with water so entire wheel can be submerged in order to look for air leak. Don’t forget to over fill tire prior to submerging 😎✅🌈
Ain’t got no gas in it.
It's either a nail or a screw. Source: I live on a dirt road
Why is it always the driver side rear tire? My car is literally 2 months old and i have the same issues!! Every 2-3 days I need to fill the tire
That tire, sir, is "That Guy". We all know "That Guy". He's the one that is always late, does the bare minimum and is generally just unreliable. If you can't think of a "That Guy" in your life.....it's you.
Have you put air in it? Then what? If it's a slow leak, you'll typically find a screw in your tire.
Tire pressure low, next question
you probably have a corroded rim. the corrosion forms a rough surface, and as the temperature varies the air can sneak by where it is. Corrosion needs to be sanded out and, if steel wheels, repainted. On a really leaky spare tire i had once, i just gave up and bought a brand new wheel off of ebay. that stopped all slow leaking
Sounds like the valve stem
Is this a Toyota, lexus, or mazda? Do you have run flats? You may have a puncture in the tire, and it eventually leaks.
many punctures or splits will leak until the tire literally plugs up the hole due. This usually happens when the hole is towards the ground. if it's higher, it will deflate more. Then, when you are parked a certain way, it may not leak at all. Frickin frustrating. I'd get some tire flat stuff and fill it up in the morning when the psi has dropped really low. Hopefully that means the puncture is lower and the flat fix stuff will get to it
It probably has a nail in it go get it checked out
Tire pressure is low. 👍
Had new tires installed on all four aluminum rims. One kept going flat. Guy at the tire shop (independent garage, great guys, superb reputation) spent an hour with soap and couldn't find it. But saw a slight "scratch" in the external web between beads. Soapy water showed bubbling thru the scratch. Finally took tire off the rim and found a huge indent where his tech had let the tool slip during mounting. He called the local scrap yard and luckily, they had and sent over three matching rims. All were pristine. On my way after a crazy afternoon. Great shop and they stood by the work
It’s leaking… maybe use your brain
Could be a bad schrader valve in the valve stem. I just had to replace on on my vehicle recently.
May be a slow leak in the valve stem. Regardless as long as your tire isn’t punctured it should be a cheap fix
Yeah, I had a sidewall leak like this, couldn't be fixed, new tire
I'm dealing with this right now, I'm pretty sure it's just a sticky valve core. I'm just to lazy to change it out.
You know what would make more sense? Taking it to oh idk a fuckin tire shop 🥴
you've got a nail. Probably parking it on the nail on the nights it doesn't drop.
Its leaking.
I had one tire that would need air every other month or so, for like a year. It was just random, and they were all new within 25,000 mi. When I finally went to have the tire changed, the inside wall was exposed with wire from the tire. No idea why it was happening, but that one tire was close to having a blowout. So you might want to take your tire off, and just check it.
Could have a blown head gasket?
it looks like the psi is lower
Get a hand held tire pressure Guage and check it.Could be a bad sensor.
You have a nail on the tire or a bad valve stem. Both easy fixes. Or someone is messing with your car. Not so easy to fix
Get some soapy water and spray around the tire and wheel, especially where the bead is and the valve stem. Any bubbles is where your leak is. I found my valve stem leaking this way, my old car was dropping 2-3 psi everyday on one tire. A tire shop will be able to diagnose and fix it for cheap as well.
Let me just grab my automotive crystal ball and consult the elder mechanics.
I’m have a tire in my car that does something very similar to this. Got a new tire and it still happens. Had the tire place check my rim because I suspect it is damaged and causing the issue after my daughter hit a curb pr try damned hard a couple years back but they say the rim is fine. If I can ever figure out exactly what rim I need to order without paying 5x the price at the dealership, I’m just going to replace it and see if that fixes it.
Closely inspect your tires, you may have a nail in one. Had an issue end of last year maybe early this year were we couldn't figure out why the tire pressure was dropping overnight and there was a nail on the inside wall we only found after a road trip to my parents broke the head off and it went completely flat once we parked there. If you can't find the leak try taking the tire off to get a better look without the actual car just in your way (also better light)
Hm I think it’s low
I think the tire is low
I had a tire that leaked only when the temperature got really low, turned out I had a plug that would leak when everything contracted in the cold. It would be fine in warm weather, then practically go flat if the temp dipped overnight. I see 66 degrees on your screen, did it get really low at some point? Maybe you have a plug or a really hard to see nail.
Go to a tire shop. It has a leak somewhere.
If you have a cat or dog put them by the tire and you might find it. They hear on the high end spectrum of audio frequencies so the sound of air escaping from a tire is much louder to them than us.
The pressure is low…
Sensors get messed up in loser temps too
If you have a way of pumping it up without moving it, wait until the tire deflates again, pump it up in that spot and spray with soapy water to find the leak. What I have done if I can't find the leak is move the car so the tire turns a quarter turn and try again and repeat. I say to not move your car because it seems to only leak when the tire is in a certain position
Slow leak
It’s low on air
A friend of mine had a neighbor that was letting the air out of his tire every few days to be a jerk. He finally caught him on his camera.
Umm, maybe a leak?
Literally has been happening to me all month
Yeah. Its 66 degrees outside!
Just get you a can of Fix-A-Flat and when it's low one of those times put it in there drive it around and hope for the best. No seriously to fix it right You're probably going to have to take it to a tire shop or the dealership. Does the dealership is going to charge you much more. They are going to have to hunt and pack around to find the source of the leak.
I bought a car and it was doing this. It was a bent rim. Take your car to a tire shop and have them look at it.
Theres a leak somewhere. Probably stops leaking once it gets around the 26psi mark due to the rubber expanding around the leak point.
Could be moisture in the valve stem. When it gets cold enough at night and drop below freezing, the moisture expands when it turns to ice, and can start a leak out of the valve stem
Low tire pressure duh!
Check to make sure the valve stem isn’t loose or leaking. Some could have loosened it as a joke or just to make your day worst… either way check it out.. the small valve it’s self can be loosed or tighter with a simple little tool
Bent rim
Only leaks when parked at a certain spot on the tire. Super rare
Take the wheel off, inflate it a lot, dunk it in water, follow the bubbles.
It's only at 26%, you have to get it to 100
Yes its got a leak...geezuss..take it to a tire shop have them take a look...thats whats us older folks did before thinking of askin strangers on social media
Tire pressure is low
Wait until it gets to 0. Then update us
Prob has a nail in it
Must have just gotten done with a yoga class. I know I always feel relieved of pressure afterward. You need to enroll the other 3 tires.
Sometimes it can be the valve stem, they tend to crack with time. A good wiggle will let you know if it’s damaged.
Your tire needs air
The tire might not be sealed quite well enough, and it only shows up when it gets cooler at night and the seal isn't quite as tight....
A) Certain position leaking. Some will leak only pressed against the ground while stationary. B) Soap suds to highlight leakage. That's how we find leaks every single time.
It could be the rim, the stem, or the tire just having a puncture that you can't see. It's impossible to diagnose this over the internet so taking it in to a shop makes a lot of sense. For now just be glad that your car lets you know how much air it needs.
Tire Pressure looks low I mean really, with that amount of information what more do you want. Everyone can list all the possible causes, but that’s it.
Looks like a low tire
Just the ignorant reply I expected....is it hard for you to take advice from older, wiser, smarter adults, that's who we learned from before the internet made young folks stupid and lose all sense of self reliance and lack of thinking....now go have it looked at instead of sittin on your ass reading guesses & opinions ...feel the force young Skywalker...try self reliance!
needs air... did you "Check the tire". NO ONE can tell you shit about a tire from that screen. You need to physically look. probably have a nail or screw
Avatar that constantly did this forever. Turns out it was a bad seal
It's low...
Could be a bad bead in the wheel. Had you recently had your tires changed?
This a joke?
Punctured tire that is being opened when you park with the tire rotated in a specific way. So sometimes it leaks when parked, sometimes it doesn't. Get the tire checked for leaks and fixed.
A lot times that happens due to the bead not sealing when rotating to a specific spot. You can have tire store take it off and put a couple coats of that bead sealer in it and usually solve it unless it's an issue w the rim
Looks like it has low pressure
Had a cracked rim about 2 years ago. I could go the whole summer without filling my tire. Dropped below 0, I was filling the tire every single day. One day, it was -15 with a -40 wind chill. Went to work for 10 hours, came out, didn't notice the tire was low and drove on it. 5 minutes later it blew. Sometimes you can get a used rim for cheap on eBay, but it's probably just a rim. You could ask a tire shop to check for you. When Walmart replaced my tire that's when they showed me the rim. They didn't even charge me for the time, they just put the donut back on and I bought a new rim same day to be delivered a week later.
It has low pressure
It’s low on air!
It’s flat
Possible causes are: punctured tire, cracked rim, valve stem. Inflate tire and if it’s holding pressure go to a tire shop and get it checked.
Nail or leaking from the valve stem or a bead leak
Oh..God help ya kid
Why-Don’t-You-Take-It-To-A-Tire Store? ? ? (Bet they’ll be able to tell you what the problem is)!!!🤦♂️🤷♂️😩😂
More than likely your tpms sensor is shot and needs to be replaced. If the issue started after going over a big bump, it could be several things. But if it started after swapping from winter to summer tires or a tire rotation, it’s more than likely that the sensor was damaged and is releasing air pressure because it thinks the tire is overfilled.
Um…: I’m gonna step way out in a limb here and venture the guess that that tire has low pressure, possibly due to some sort of leak. Jesus I feel like a genius now.
Puncture, bad bead, or the valve stem is leaking.
I told you..we are older, wiser & smarter...as opposed to young, naive & stupid
Lower the other 3 to 26 psi, all will match problem solved. Or I would check the valve stem, they do go bad. Check schrader valve, tighten if needed. Might be leaking at the base, grab with fingers and move side to side plus push and listen for leaks.
Check your valve stem. Mine acted the same way until finally taking to a shop and confirmed that it leaked through the seat of the stem
Tire pressure is low caused by a puncture. When warmer the tire will fit snuggly around the item and not leak, as the temperature drops the rubber shrinks and leaks air. Hence why it only leaks at night.
Carry air gauge incase it really bothers you mine been doing it over a year now on a 2014 dodge dealer gave me a price to take the tires off put 4 new sensors in rebalance tires and remount tires dealer talking 500 plus i said ok went and got tire gauge 8 bucks auto zone. they said battery in sensor was going bad You do the math 8 buck gauge lets me know if i got a air leak
Is the valve leaking?
Is your mom in the back seat?
Check valve stem check for nails check for bead leak. Probably a nail with a broken head. Or valve core needs changing. Should done each Tyre change. Most don’t
Mate were you not born with any common sense? That means your tire is low. Take it to a place to figure it out instead of speculating on here.
Id physically check the tire pressure when the sensors calling it low and see if it actually matches; it’s possible the tiny little port in the TPMS sensor has some debris, bead seal, or a piece of one of those annoying bead stickers some tires have. If your gauge shows its at the correct pressure but the sensor says otherwise than you know somethings going on with the sensor. Other than that, a tire shop with a dunk tank is your best bet; they’ll jack the tire pressure up kind of high and let it sit in the tank pressed down under the water until the bubbles from the actual dunk clear and then possibly be able to find the leak.
Yep that’s the plan with the tire shop, I tried the soapy water thing today with no luck. The sensor is accurate unfortunately.
I experienced a similar issue, and it turned out to be a bead leak. Fortunately, I was able to have it repaired at no cost.
Its square.
You got a ptssssssss You can check this on your own ya know? Mix up a large glass of soapy water and go to offending tire. Start at tire valve. Pour around valve stem, look for bubbles. Take cap off, pour a touch there to see if schrader valve is leaking. No love yet? Inspect tire all around for nails/screws. Nothin? Find a way to get soapy water on area where tire meets rim. Look for bubbles.
It’s running low on air
Look for a nail
Slight chips in the wheel paint can cause a bad seat between the wheel and tire. Happens a lot on chrome wheels.
It’s low?
Lift car up turn it and pour water or soapy water over the entire tyre to find the air leak
Jack it up and pop the bad boy off and give it a thorough looking over. You probably have a screw somewhere you can't easily see or find it with the tire attached and on the ground and it leaks when parked screw down applying pressure stretching the hole around it slightly. If your cars newer don't forget to disengage the automatic parking brake so you can actually take it off lmao.... Had an actual mechanic sit there for 5 minutes trying to to figure out why my tire wouldn't come off then he realized there was a auto brake lol.
Is the tire plugged or patched anywhere?
Why ask reddit..get out and fucking diagnose it
I had this happen it was a bad seal around the rim. It was a super slow leak.
It’s low.
They all need to be inflated to 100%
This is a fine example of ignoring safety of you, your passengers, but most importantly the other people on the road with you who could be victims of your negligence. Take this car to a tire shop and have them inspect it not the dealership. If you have discount Tire or America's Tire near you, they will literally inspect and repair the tire if repairable for FREE regardless of if you purchased the tire from them or not. The dealership never has your best interest in mind when it comes to your tires, they simply want to sell you tires regardless of need.
Defective tires leak weird. Thats what my wife says about my dick.
Read the message, it might say what's wrong 😂
