hello i had some 275r60 vipers mounted to the 10 holes mounted on the back of my car, the back end was up in the air and they looked wicked. has anybody had any good luck with vipers. what do they rate from 1-10, 1 being the crappiest. i wanna know what you think about the traction, the longevity of the rubber after a long burnout, how many smoky burnouts did you do on them. stuff like that. mine got slashed. i could do a 30 second burnout and they would look like they did before i smoked them. the rubber did not look like it came off.i liked them but i haven't owned many really nice tires before so i don't know how they rate really besides my personal experience.i know there are different vipers and i forgot what these a called but the tread pattern looks like a bunch of triangle shapes facing opposite directions.
