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.

have you lowered your car? if so this will affect camber(gives more negative thus wearing inside of tire). Sounds like who ever you took it too did something wrong. camber wont wear the tires as much as toe would. id take it back and make them realign it with you watching. curious as to what machine they use as well.
also make sure before you go your tires are at 32psi and if they do check the air like there spose to, to make them put 32psi. this will affect the measurements some.
