Abnormal tire wear?

Volcom370Z

I meant no disrespect, but I spent quite a bit of time on Tire Rack before actually posting my original posting. I also when to my dealership. I do appreciate your help, but a page full of links is kind of vague in that I didn't know what exactly you were referencing.

If that site didn't have the answer, then your car has a unique problem(manufacture defect, possible, but I doubt that).
Do both rear tires have abnormal wear?

I doubt it too. I can visibly see the negative camber in my rear wheels, yet it seems that the outer most rib of my stock sport tires wears out faster that the insides. It should be the other way around. I've also checked with my local dealer and was told the wear of normal.

My conclusion is that the outer groove of the sport tires isn't as deep as the others which seemed more likely to be the problem.
