I just upgraded from stock 15" rims to 16"s on my firebird. I had cheap $60 Dunlops on it before and I bought Avid V4s which were about $110 each. The road noise is a bit better, handling is about the same, and about the same amount of traction. Basically its nothing impressive. I'm really disappointed and wish I had just gotten $70 Faulken tires now. Just thought I'd mention that since I always laughed when people told me they got really cheap tires and how expensive ones are so much better.

 

avid V4's arent really much of a high performance tire, so theres the problem
