In Reply to: Pirelli's and Cupping... posted by Sean on January 05, 2000 at 07:43:38:
: i'm with sean on this one... my front two P7000s are horribly cupped. no racing, not even a driving school (yet), stock suspension on a 95 M3, had alignment checked out 5000 miles ago, no damage to suspension components, etc. but the tires still cupped. unfortunately, i'll be driving on them until next summer -- i'm goin for the Yoko AVS sports as a replacement, best performance value IMHO. check the archives for more info on this subject; pirelli tires tend to have a cupping problem. another question for anyone out there: does heat cycling new tires before mounting help any? someone suggested i do this on my next set of tires.
: My buddy had a 96 M3 that came with P-Zero's and they did the exact same thing! It had a stock suspension and he drove it hard, but the tires looked like sh*t! Loud as hell and squirmy...should not have happened on a car that NEVER saw the track.
: My advice: BUY ANOTHER BRAND!
: If you have the cash, buy the Pilots or the S02 Pole Positions. If you are tight on cash, buy the AVS Sports. My $.02...
: : I am on my second set of Pirelli P7000 Supersports and both sets have had cupping problems. The set i have on my car now has about 5000 miles on them. Do people think i should trash them and get another brand of tires or should i wait until the tread is worn down more. The tires are starting to get real loud and are starting to shake again. By the way i have had the car aligned twice, so i know that is not the problem.
