Normal tire wear?
 

So I noticed that the inner most portion of my rear tires are at 2/32", and the outer most portion is right around 4/32". The center of the tire is probably in between the two. I know the stock settings have a bit of negative camber, but does this amount of difference still seem right? Suspension wise everything is stock except I have 20mm spacers on the rear.

do the V12's have inner reinforcement belts on the tire tread like most asymetical tires of today? if not, this is pretty typical. try using a tad higher psi (37-38).

I think its normal my z is the same way with tire wear. You can rotate the tires to help them last longer. But you have to dismount and mount the tires to do so.

Okay cool, thanks guys. I figured it was normal, but thought I'd ask. Was just surprising when I went to check my tread depth to see when I needed to replace them, and I went from "oh, I still have probably 3-4k miles left" to "crap, I need to get new tires very soon".
