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.

If the outside edges are worn its underinflated if the inside of the tire wears faster its overinflated. Sometimes you have to adjust the tire pressure because of the weight of the vehicle. There isnt a specific pressure for any given tire.

If you are saying only the inside edges are worn then I would suspect incorrect camber( the tires lean towards the vehicle) or incorrect toe angle
