I think I saw it wear sometimes (low pressure and lots of negative camber)... But the thread was always faster to get a puncture than the sidewall... I could be wrong though...

Not to be anal (well.. that's not true... I mean to be :razz, there's 50 that heat but only 48 that wear?

Hmm, sidewalls really should be divided up and also wear... Why only heat & no wear? What if you lock up sideways, that should hurt the sidewalls in the right circumstances... ..... ....

I must say I'm really impressed with the response

Ball bearing turbo... Yes you are anal but I always thought that anal was great when going in the right direction.

AXP... I must commend you of your hard work, what a fantastic job you have done. I have it set as my desk top, who is being anal now, cough

I'm happy that my first Post was a useful one for other people as well as myself.

I'll make sure I spend more time reading in the forum now I know that great lfs tallent extends beyond the steering wheel. "cough "

Cya all on the black stuff

Sidewalls don't touch the road.

They do if the tyre deforms - real track cars regularly have sidewall wear after a long race, especially slidey cars.

What are you calling a sidewall?

The side of the tyre, that joins the 'tread' to the 'bead'. Where the writing is. I've seen (and done it) half the writing worn away from enthusiastic cornering with the wrong tyre pressures.

Many tyres have a shoulder section between the tread and the sidewall, are you using more than the shoulder?

It's not unknown. I must admit it's rare, but I've seen it before. If you use cheap road tyres on a track (for a trackday for example) then it's more likely.

Yeah it's an eye-opener though. Deflation would probably be my first concern (bead can come away from the rim easily under these conditions, causing a loss of pressure or worse). The other problem is debris. Sidewalls are typically made to allow the tyre to flex and change shape as pressure changes, they lend themsleves to punctures by sharp objects rather wllingly. But I suppose many races or positions have been won by using "that extra little bit" (of luck).
