So i'm looking at the Pirelli P Zero Nero M + S. Anyone have them or know anything about them? I was checking out tirerack.com and they rated the Avon Tech M550 A/S pretty high. I've never heard of them, anyone? I don't want a tire for pure dry performanc, it needs to perform well on wet roads as well. Snow traction is not an issue because I have snow tires. Thanks to the best bmw forums site!
