So i got some Dunlop Direzza Z1 tires for the Celi 205-50 R16. had the car re-aligned within a week. Anywho they ran fine for the first 2000 miles then the car started to rumble and I shrugged it off (because of a different problem with the harmonic balancer). When I was rotating the tires I noticed really bad cupping on the inside of both front tires. I checked they cant rub on anything, struts are not great but still pass the bounce test, properly inflated tires. One thing I should say is that the cupping starts on the lip where the tread grooves are. The only thing i can think of is that the tire is too squared off at the lip and the cornering is pealing off the rubber. any other ideas?

Too late to take a picture.

My RWD 64 chevy needs a 4 wheel alignment, but thats cause the brackets welded to the later model axle are off a hair.

I have seen an axlehousing slide down the leafspring before though.

Just keep an eye on your tire tread. I have to run 5 psi in the rear tires on my truck or else they wear crazy fast in the center from overinflation. Its all relative to tire size, vehicle weight and sidewall composition.
