Very pleased with these tires. They stick! Sharp turns with no squeal. Sharp curves in rain with confidence. Quiet tire - much quieter than prior Potenza. H speed rating is enough for realistic pursuit. Can't comment yet on snow or wear. The set balanced fine. At this point, I would definitely buy again.
My snow and Treadwear rating are pure guess.
Recently put these on my SHO. Tire has great grip. Under hard acceleration the G-force would just spin and smoke which was a nice show but weren't good for anything other then smoking. These tires really have a lot of grip and hold well in the corners. The SHO is a very heavy car and So far these tires and holding up very well. I am hoping to get 35k out of them. Lets see how it goes. Haven't been in the snow with them yet.
