Why does my DSF tyre keep losing air?!

[bobby]

My DSF tyre has recently been behaving strangely!

Normally I run 35psi at the rears and 33psi at the front.

However after a couple of days I will check the DSF tyre and it will be 19psi?!

Anyone got any ideas? Is it a slow puncture>Why doesn't it lose more than 19psi?

give it time and it will lose more pressure

however, one possible cause (please tell me if im wrong as this is a guess) if its just one wheel doing it, it could be mis-shaped or a small crack in it, and when it deflates to 19psi it fills the loose area up.

Then again i could be talking out my ass

Just ignore my stupid question it's just that I have always known the sides of a car to be the near and off sides, so would have said OSF tyre instead.

Hello wifes b class tyre monitor kept going off as one tyre doing exactly the same 33 to around 19psi over a few weeks.

Anyway while I was having my new wheels fitted by a mobile tyre man I asked him to have a look. It was the seal round the tyre part of the inside of the alloy was slightly corroded. Rub down with wire brush new tyre sealant on and refitted = fixed

It could be the way that the tyre sits on the rim as per Gunnings' post. I have had one or two tyres in the past that have been perfect after the tyre fitter has reset them on the rim.
