I am getting a bad cupping on my rear tires on the inside. Due to the coils i do have a slight bit of negative camber but neither of my last two sets of tires had any cupping at all. Car rides smooth no bounce or noises that sounds like a control arm. What are some things i should be looking at? Blown coil? Worn rear control arms? Any ideas? TIA

Tire make? Some are WAY more sensitive to cupping than others.

225/45/17 Yokohama S.Drive is the tire. Have only had them a few months. Previously had fk452 and no issues

FWIW, on the bimmer I saw minor cupping on Goodyear F1A and some Pirellis, but never on the 2 sets of FK452 I had in between the two.

FK452 is a quality tire for such a budget make. I am very much impressed with them, especially since they lasted 1.5 times longer than the F1A's, stood up to the car's weight better (the F1A's would warp temporarily, when parked more than one night) and no cupping - at all. All on the same car. So either the FK452 is a very good tire, or the Goodyears are total shite. Bit of both, probably.
