I might have roll on it for few miles ... days... Could i have damaged tire or wheel ?

[Frenk]

I think it's the valve, no air coming in/out. Is this something universal ?

is it a runflat?

If you've driven on it a decent amount, I'd be more concerned about the drivetrain. The xDrive setup is only made to tolerate a certain amount of variation in the diameter of the wheels/tires. Though as long as it isn't making any funny noises, you might be okay.

At the end of the day, it'd be best for you to have it looked at by your dealership or an indy shop if possible.

I doubt you would have rolled on it for a few days without noticing or without someone else on the road noticing and brining it to your attention I always alert fellow drivers on the road if I see they have a flat tyre. I would like to think that others would do the same for me

can I let the car sit on the flat tire for another 24 hours wihout futher damaging it ? I really can't fill air in the tire.

Judging by the sidewall look, does it look damaged ?

[dkexige]

Too hard to tell, there are way too many gaps and shadows playing tricks on the eyes.

I would say if you drove on it any significant distance that the tire would likely be done. They are not designed for thousands of pounds of force per square inch digging into the tire inbetween the rim and the road.

If you have another set of rims, throw one of those on there and drive slowly and carefully to a shop. If not, I'd consider getting it towed.

You can't have driven on that for long without noticing. Just get it checked by a shop man.

So you have non-runflats and no back-up plan? If you've been driving on a tire that flat for days, the sidewall and rim may be damaged. No flat tire warning? Change it now, don't drive more.

UPDATE

I got it towed to the garage. They told me it was leaking from the wheel .... How can they be sure it's not leaking from the valve ?

I had mine leak at the tpms sensor (bad seal). Have they said they've found a crack?

Maybe there's a crack in your wheel?

No they said air was leaking from the seal between the tire and the wheel. This is reputable place though.

Is there a chance they couldn't see the crack ?

[Frenk]

just had the same fucking thing happen on another wheel, different garage : same result.

[Frenk]

well .. it did the same thing on 2 others tire .. so I re-did all 4 tires ... I seriously hope I didn't end up with malfunction OEM wheels ...

UP. Anybody knows what can cause 3/4 tires to lose air only in cold weather ? They were still at 32 psi during all summer.

It is making funny noise now ... about one year later, could it be related ? Grinding noise when turning on both direction and even when not turning though.

Yes, tires naturally lose pressure over time as the air diffuses through the tire. Its very very slow but that coupled with a small crack in the wheel or a small nail in your tire plus the colder weather could all contribute to the tires losing a little pressure.

Last year, I got my first flat 16 days after installing tires. Second flat happened one month later on different tire. Decided to remount four tires. Third flat tire was going to happen. Its a fast leak only in cold and/or when tires under car weight. Let me know if you have an idea.
