C4 tire problem
I have an 86 pace vette. It has 1989 vette 17 inch wheels. The rubber is Goodyear. The problem is the left front tire. 2 inches from the outer edge the tire is cupping. The right side is fine. I run the tires with 36 psi and check them often. The back tires are fine too. I have replaced the front leaf spring, A-frame bushings,swaybar bushings, had the ball joints checked and a front end alignment all about 25,000 miles ago. Anyone have any answer. 
Thanks

Cupping can be caused by several things but it is usually alignment and/or a loose part if on one side. In 25,000 miles lots of s*** can happen.
