: 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.
