I've had two sets of these on a 2001 Nissan Altima GXE 4-dr. First set developed severe cupping on the rear (guess I was a bit lazy about rotation). Dealer advised that rear struts needed replacement. Did that (and rotated tires more regularly). Don't know if any more cupping developed on that set, because the noise from the others would mask it.
Anyway, put another set on, and they began cupping on the rear as well--even AFTER new struts.
Didn't have this problem with tires that came on the Altima.
Is this a typical problem with Coopers?
Oh, they are supposedly "low-profile" tires, and the dealer advises that inflation should be 42 lbs.
Also, the Altima DOES tend to be very light in the rear. Some have suggested that I carry a bag or 2 of sand in the trunk to provide weight to keep the rear end from bouncing.
Thanks for your comments.
