lol....sorry bout the confusion. the a032r's have a DOT approval, but youll only get like 5000-7500 miles out of them. they are ok to drive on the street, but they are also menat for use on the strips and courses. cuz i was gonna do these, and just take em with me to the track and change them at the strip/track. also, if you pay attention to the measurement of tires...this tire has 6/32 to start out with, where your normal high performance/all season tire starts out at 9-10/32. i get bored easy at work and all i do is look at our yokohama book...lol
