the racemaster drag radial in a 275/60R17 I think. I know it was a 275 and a 17 in wheel. Although size is not all that relivant. They worked great for us. Now even though those tires have been used for a few years, that's is not street duty. But when I owned them I made probably 150-200 passes with them at the track. And I love a good burnout. They probably have 60-70% of their tread life still. My buddy drove on them to the track 3.5 hours from his house made about 6 passes and went home. He does that a few times a year. Probably made the trip 4-5 times with them now. And I have not seen them in a while but I bet they have 50% tread life left or more. Since I gave them to him. They have outlasted the slicks I picked up to replace those awhile ago that's for sure.
