My car was kinda shaky in the front above 45 so I thought it was alignment, alignment done and still did it, thought it was balance....not the balance but when I had the car on the lift and on the balance machine the inner edge of tire had flat spots, you could feel them and see them. They are falken452 20" Vossen CV1....anyone have this problem with tires...?

 

could it be cupping? http://www.ehow.com/about_5509983_ca...ing-tires.html
