QUOTE=Z K;13619372]If you mean the Car and Driver review when you say tire reviews, I wouldn't say they are the best at determining what are the best in ultimate grip. They are consumer oriented magazine and their reviews look at tires in a more overall sense. The PSS gives good bang-for-the-buck but it can't match the gripper rubber.
Grassroots Motorsports has better tire reviews if you are looking for tire grip and don't care for the overall tire evaluation. No one in their right mind would go compete in a street tire class autocross on PSS. It is not competitive.
They evaluated the following tires last year:
Dunlop Direzza Sport Z1 Star Spec
Hankook Ventus R-S3 Z222
Bridgestone Potenza RE-11
Kumho Ecsta XS
Toyo Proxes R1R
Yokohama Advan AD08
Time-wise they finished in this order:
Hankooks, Yokohamas, Toyos, Kumhos, Bridgestones, Dunlops
