Huh?So i have some "Summer Ultra Hight Performance" tires on my car and they have been on sense i bot it in November and was wondering. if there summer tires and i have only driven on them in cold weather under 80 out side and may be 7 days of over that. what kind of addition in grip would i be looking at when it heats up or at the track after a few laps of them getting warm?
