I have had 2 sets of Pirelli p7000 supersports and both pairs have had a bad cupping problem. I have had it aligned twice and that hasn't helped. From the responsed from other people on the board it sounds like this is a common problem with these tires. My question is should i just go buy another brand of tire even those my tires only have 6000 miles on them, or should i just try to burn my tires up and then get new ones when their is no tread left. The tires are getting really loud and i am starting to notice a little bit a shake.
