My review from these tires is that they are a very good performance tire. They allowed my BMW to be very responsive to the road. However, I won't be buying them again. I live in the NYC/New Jersey area, and the roads have simply ate my tires. Multiple bubbles (from even the smallest pot holes), the tire walls on all four tires exhibited cuts in the walls etc. So while I will rate this tire highly for road performance, its not a very durable tire. Especially for tough City road conditions like NYC and Northern New Jersey.
