Yesterday morning, just as I’m arriving downtown for work, I get a call from my fiance saying she has a flat tire. I jump in a Lyft and head her way to discover that she wasn’t lying, the tire is flat. Mind you these are brand new tires, only a couple weeks old.

Since I had an air compressor in the trunk I decided to see if it would take any air. Sure enough, I was able to fill it to 40 psi without issue and there were no obvious leaks and no debris sticking out of the tread. I drove it back home and parked it, fully expecting to come home to a flat tire again.

Well it held air all day, and all last night like nothing happened. I’m so perplexed, I’ve never heard of a tire going completely flat without some obvious issue.

I need to bring the car in for an alignment anyway, but I don’t even know what to tell them about the tire. Its the weirdest thing. She said she was driving and all of the sudden she was on the rim. ¯\_()_/¯

The beed around the rim probably wasn’t seated correctly. T he tire going flat and then being pumped up seated the beed correctly and now the tire holds air. This has happened to me a couple of times when airing down/airing up on my truck.

Is it possible the bead got unseated? Maybe a pothole or a certain turn somehow opened up a gap.

I had this happen to me as well. Left my apartment and I’m pretty sure the tire was full when I left (I walked by it) and arrived at Home Depot and it was completely flat. AAA guy pumped it up (to 56 instead of 38 ), and it held air perfectly until I replaced a year or so later. I have no idea how that happens. Is is possible for the bead to unseat and burp out a lot of air or something? Valve failure that somehow fixes itself?

What the others said. One time I parked close enough to a curb that it pushed on the bead and flatted. Pumped it up and all was fine.

But don’t discount a slow leak from a puncture. I drove from Dallas to Houston on a tire with a nail in it. It lost like 5 pounds a week, but I would top it off and keep going.

Don’t do that by the way. I should have had it checked sooner.

No offense but does she have ass*** parking habits? Taking up two spots, parking in handicapped zones, etc?

I’m betting on the bead

No no, although I suspected foul play initially. We park on the street in front of our house and everyone usually plays nice.

Could’ve been a pothole too. Our neighborhood is lousy with them. I usually park as close to the curb as possible, so she could’ve rubbed it when she left.

You can never go wrong thinking the worst of people!

Could be, our neighborhood has a lot of potholes.

Weird, but plausible . There was an awful lot of sealant on the rim when I got them back from the installer, so maybe they sealed up something that should have been reseated. Tires are one thing I’m admittedly ignorant about.

I had that happen once. Car drove fine (‘89 Prelude 2.0 Si), pulled in hard to my apartment complex (left turn)

Rear right tire immediately and completely flattened.  Reinflated, and never ever even leaked again.

Maybe someone bled the air out of the tire?

Pebble in valve stem cap? I had a friend that loved this trick, you have to get it just right but you will have a slow leak... Does anyone hate you?

I’ll tell her to stop trail braking and not trying to nail every apex on her commute.

I just asked her though and she said it was immediately after she took a right turn. It was the left rear tire, so this is consistent.

Yes, obviously a great many people do . However, I don’t have stem caps on these wheels.

In point of fact, I did nail that apex.

I once ran over a screw in my old Abarth. Exited the car and could actually hear the air leaking out. Found the screw, pulled it out, and the tire completely deflated. I refilled the tire with sealant and air. Took the tire to get patched, and they couldn’t find the hole. Dunked it in a tank, no bubbles. Asked me if I was sure it was the correct tire, I was, so they pulled the tire, it was filled with sealant, but they still couldn’t find the hole.

Drove the car around for another couple months before it deflated again. That Mopar sealant was some heavy duty stuff.

The Civic’s old tires would do this and it was weird. They’d lose pressure, I’d fill them, and they wouldn’t lose a single PSI for months/weeks and then suddenly would drop 10-15 PSI overnight.  Never found a cause, but then again these tires had at least one plug in the sidewall so... they’d led a rough life.

Do you think that could be from the dirty fuel strainer too??

Yes.

It’s possible it was the valve anyway. Perhaps the little gasket in there wasn’t seated well in there before, after you filled it the gasket sealed properly.
