Do we know of any high or ultra high performance tires that include a treadware warranty? Also, we really only need R speed rated tires (up to 106 mph) so does getting something better deteriorate easier? I had Kuhmo Supra 712's before and barely got 2K out of em with NO burnouts or anything like that so im trying to put two and two together before i have to replace them for my inspection coming up.

2k? thats it?
are you sure they were on right?
