I think DVW can confirm this, on my GTX i have a set of hoosiers 14.5 x 32 x 15's that have been on the car for over 16 years, DVW has even put a plug patch in one. And the tires hook every time with very little burn out in my blown 68 GTX, best 60' 1.21 they hook good enough to rip the out put shaft right off the planetary. lol
