The only problem with them is that because they are so grippy on dry pavement, they have a very low treadwear rating of 200 which means as a set of daily driven tires, they will get eaten up on regular roadways pretty quickly because of their fairly soft rubber compound...I do like them as a part-time street tire for racing purposes, but i would never buy a set as daily driving tires...of course, i would never drive a car on DR's every day either and plenty of people do that...
I run a higher treadwear street tire 300+ for everyday driving and I put on my R-comps for competition events...of course, R-comps are NOT in any way, shape, or form made for street use, even though they are technically DOT approved...
