I have had several cheap sets of tires and going from knockoffs or cheap PZ-900 to the super sports. NIGHT AND DAY difference worth every penny. With my little car I stick to the road. I used to hit corners at 75 and hearing tire squealing and with theses I can hit 90 and feel like I can go faster. Only negative thing is that they are 180.00 versus 60 on the cheap tires. I feel that since I can hit corners at that speed I've worned down my front set down to 60 percent and rears at 80 percent in 2,000 miles but if I rotate and take it easy I think I can get a lot more out of them but its too much fun to hit corners and feel like I'm on a admusement ride in my car.
