Flat tyre

Kingsd316

Hi All

Is it possible to go over a speed bump to quick and have most of the air from the tyre come out, the reason i ask is because before i went out my last night my tyre was fine, then when i got in it was down to about 6psi (only out for about 1h 30 mins), i pumped it up and left it over night,this morning it was at the same pressure and hadnt lost any air.

I cant work out what could have happened, if i had a hole in the tyre it would have been flat this morning, and if it was a slow puncture it wouldnt have deflated as rapidly as it did last night.

Maybe the way you parked it overnight meant the hole was against the tarmac creating a seal?

Good point, will move it tonight and see if anything changes

or if there is a nail/screw/stone/object in the tyre, it was resting at the right angle to cause air to escape?

Someone let your tyre down?
You parked liked this at some point?



Tyre's can also release air when moving if they're not fitted correctly......

No not parked like that (so far as i know) im hoping someone let it down as i dont want to replace the tyre as it cost me £140 2 months ago, although if someone did let it down they went to the trouble of putting the cap back on the valve.

I had a problem like this some years ago. Tyre would suddenly deflate then OK for a few days then deflate agin. Kept happening at random times and no puncture could be found.

It transpired that the fault lay with the alloy wheel. I forget exactly what the correct description was but basically the alloy had a dent which allowed air to escape if the seal between alloy and tyre was not exact.

Check your wheel for small dents after the contact with the speed bump.

Yes. I had a similar problem years ago loosing a lot of air going over a pot hole too fast.
