Tire wear

[Maniac]

Even at correct pressures as camber causes the tyres to lean in you will get some extra wear on the inner. Poor tyre maintenance will make this worse, notably so on run flat tyres. It's a very expensive learning curve.

My previous Car exhibited similar wear - the dealer said it was fairly typical.
Not sure if I believe him now - one thing is for certain I'll be keeping an eye on the new car!

I'm just about on 23,000 miles and just had the first service, tyre wear is worse on the front than the rear @ 4.0 mm front vs 5.0 mm rear!!

Yes run flats what pressure should they be ?,the tire centre put them at 32 psi when I purchased them

36 front, 44 rear.

Perhaps* this explains why they've delaminated.

(*No sarcasm intended. I don't know enough about tyres or steering/suspension geometry to say.)

Running at least 10psi under pressure at high speeds for k's of miles. I'm quite impressed the RFTs stood up so well!

I think the pronounced negative camber and the distinct lack of deflection the side walls allow is the main culprit - under inflation will make the side walls work almost as if punctured.
