I jacked the car up today and had a good look at the rear tyres (fronts have got brand new tyres on but rears still have a few months left in them) and noticed that the rear left tyre is quite a bit more worn than the rear right. Does anybody have any idea why this would be?

I think the rears are alligned correctly as Ford must have set them when I had a suspension geometry test done. Without a new set of tyres on the rear it will be hard to work out if it was the front tracking causing the rear left to wear.

My rears are in the exact condition as yours. The rear left is also worn down on the inner edge considerably compared to the one on the right. Maybe it has something to do with camber on the road because it slopes down in that area???

Are you sure that the tires are actually worn more on the inside? When the Pirelli P Zero Neros wear past 50% you can be fooled to think that they are unevenly worn because the grooves on the inside are not as deep as the ones on the outside. The inside therefore "looks" like it's worn more but in fact if you measure it at the first "longitudinal" groove it will be the same as on the outside.

If you've replaced your tires with something else ignore this post...

Thanks for the reply Nick02. I've got AVON ZZ3 tyres on my ST though!

Are the P Zero Neros the tyres the car comes with from the factory?

Ah, thanks.

When I first bought my car (it was several months old) the P Zero Neros were in one hell of a mess. So much so that the inside edge were down to the metal.

I've put AVON ZZ3s on the car ever since. They look very nice and handle very well on the road. I've got brand new ZZ3s on the front. The rears have a few months left in them.

I also have the ZZ3s on the front and I am loving them, so much more confidence in them than the P Zeros
