RFT/leaky tyres

Hmmm Sorry to dig this thread up - I think I may have a similar issue with the front wheels - PSI keeps dropping even on brand new tyres.

I have 103s so not ensutrely sure where the problem could be but it is starting to get really annoying as I just spent nearly 400 quid on new tyres assuming I had a slow puncture.

Any recommendations for how to check if the air leak is there as a result of damage to the wheel?

Apart from minor scratches there are no obvious visible issues with either of the front wheels.

Drop the wheel in a trough of water. Most tyre shops have one for just such purposes. If you can't do that then lie whe wheel on it's back then face (on a soft surface) and fill the rim bead with water and the also valve. You should spot bubbles. Withe the tyre wet you can often spot leaks there too.
 
Thanks again - you're very helpful.

Just so I know up front - if the leak is coming from the wheel itself (poor sealing between wheel and the tyre) would that typically mean that the wheel may be damaged and needs replacing? Or are there other ways to correct the issue

The wheel in this case probably just has some corrosion on its inner lip which is stopping a good seal. Nothing a wire brush wont sort out :)
 
If the inner lip is too good (smooth) it might leak too haha.

My newly reconditioned 107's and Eagle F1's go down very slowly (nowhere near as bad as my 108's and Bridgestones)... either way I need to check them every few weeks and add 4psi or so!

I think they leak a bit every time you hit a pot hole on low-profile... my high profile tyres on older cars would last from new to replacement and stay the right pressures...

Wire brush Ed - another of the Devil's tools, second only to the Birmingham screwdriver :poke:

Not that it helps in theis instance but 108's can also leak through the bolt holes. Although blind holes the bottom can be porous and leak around the thread :thumbsdown:
