I'm about to get a new set of Pirelli P-Zero Nero M+S for my SVT. The stock contis are practically done for after 16K miles.
Pirelli P-Zero Nero got a 400 treadwear rating, A for traction, and A for temperature. As for Z rated tires, I think W rated is more than enough for the street.
The Pirelli P-Zero Nero got a very good rating overall on tirerack
. I have also considered Kuhmo Ecsta ASX and Nitto NT NeoGer ZR. I have used Bridgestone Potenza RE750, but I have reconsidered using those after using RE730 which was somewhat noisy, but excellent traction and wear on a AWD car.
