Pirelli PZeros are getting a bit of a bad run here. I'm a bit surprised as previous tyre threads have rated them as pretty good. I have PZero Rossos on my GTA on the 18" wheels. They were an immediate improvement on the Michelin Pilot Sports they replaced (although I'm told the PS2s are much better). I've had no problems with aquaplaning and all round performance seems good and wear is reasonable too. I'd have no problems buying them again.
