Warning on those Pirelli PZeros. They're impossible to find and the tread wear will give you about 15K miles. Also, they're made for each side of the car, so there is no 4 tire rotation (in most configs, though some cars may have all 4 tires of the same size) possible.

Tirerack.com under Pirelli has a write-up on them with customer comments.

Not being able to do a four wheel rotation is nothing new... most performance cars have unidirectional tires that allow only front-back swaps... (unless you have a Vett or NSX where the fronts and backs are different sizes...

I never rotate my tires... I just replace the fronts (FWD) when they are needed... on the fourth pair of fronts with the same rears.....
