ive got about 6k on my new Falken STZ 04 in 285/60/18s and have noticed some cupping on both the inner and outer edges of the front tires.. i had them re-balanced and moved to the rear, but it seems like the ones from the rear that are now on the front are doing the same thing

I had my alignment checked three times since may... the most recent time the toe angles were dead on, the left side was dead on, but the right side is slightly out of spec for negative camber and right on the edge for caster

after speaking with Falken, they dont seem to think this is the problem, they are advising me to run the tires between 26-29 PSI (I was running them at 36) they also advised me that the rim is probably too small for the tire

i know many folks here have 285/60/18s on the factory wheels, are you noticing any uneven wear on them? what pressure do you run at?
