Anyone know of any reasons why my tires would cup on the inside only? I've got some Dunlop 60K (AA traction A treadwear). Had the car aligned. I bought the car with these tires on it. Struts are fine. Tried jacking the car up and moving tires laterally and vertically to check for ball joints, steering arm. Everything was tight. Even had the tires rebalanced. Any ideas???

 

Check the Camber.

 

Isn't cupping ususally due to toe in?

 

take it back to whoever aligned it & have them check it agian & get a printout

 

what do you mean cupping/ like its wearing faster on the inside? or its scrubbing the tread?

I think in one of his other posts he said "it's cupping on the inside of the tire only". I took that as meaning that it's wearing on the inside edge of the tread. That's why I told him to have the camber checked.

Negative Camber (tires look like this / \ if you look at them from the front of the car) would cause the inside edge or shoulder to wear).
