honestly im dissaointed in mine, mine look like that after a street run and some track passes,they dont last very long, my nitto's lasted twice as long and really i only cut a hundreth better 60ft with them over my nitto drags. but i have bad luck with tires, lol. i dont think i will be purchasing another set anytime soon. cut 1.75 on nittos and 1.74 on mt's.
