Tire wear

[Timdon]

Has anyone else experienced bad tire wear on the insides of the rears ? The tires have started to de laminate .

 

[The_Dude]

Wow!

That's some serious uneven wear. Get your car in for a wheel alignment check asap.

 

[Smartbear]

That's not the camber, it's poor toe in/out that causes that-get your wheels aligned asap

I will book it in tomorrow, the roads around here are terrible,full of potholes and speed bumps.

 

[Smartbear]

And perhaps check for tyre wear over the full width a little more often as well

It past it's mot last January,but I will be checking monthly from now on .

Run flats? If yes the possibly under pressure.

Run flats? If yes the possibly under pressure.

Would under pressure not wear on both outside edges?

 

[Timdon]

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

Not on rears with factory (significant) camber.

If these are rears, my 19" are 2,9 bar, circa 42psi

Run flats have very stiff sidewalls, when at a low pressure the cars weight sits on the sidewalls rather than load through the tyre. This causes rapid wear due to high rear camber from factory.

I too suffered this early on and as a result I'm fastidious about pressures and haven't had an issue since.

That plus a switch to non run flats.

That's got to be tracking, mine wear even, not like when I first had the car re; the fronts.
The rears are toe in so should wear outside. So could be too much toe out and/or camber, which is set by rotating the rear mount bolt on a cam.

 

[Timdon]

Thanks maniac I will be putting the pressure up to 42psi tomorrow ,you would think the tyre centre would know what pressure to put in considering the £200 cost per wheel !

 

[flybobbie]

Sticker on the drivers door frame shows the pressure.

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!

 

[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.

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!!

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.)

 

[Garvin]

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.
