I always thought "cupping" came from the car's shocks and springs not keeping the tire in contact with the pavement after running over bumps, etc.
When the tires were new, did you get the sensation that the tires/wheels continued to bounce after hitting bumps? (I'm not talking about a shimmy like an unbalanced tire.)
Your alignment may be off too but it sounds like shocks or springs. Do you have stock springs and shocks on your car or are thay aftermarket or modified?
: 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.
