Worn inside edges also . . .
Firestone told me 5k miles ago the inner edges were wearing faster, wife told me it was pulling right a bit, Firestone told me last week they aligned it to the max adjustment and toe / camber still out of spec. Followed my wife to SERVCO Toyota here in Hawaii (rear tires look like an old VW Bug) and was told they would check it for $130. but would probably have to install the same shim kit Firestone offered. Not a warranty issue. They agreed with Firestone that some models (Corolla) need after market kits to bring the adjustment range back into spec. No abnormal wear for first 20K miles, but we moved into a neighborhood with many speed bumps, some not perpendicular to roadway. Who knows. He thought Hawaii potholes. Guess its back to Firestone to upgrade to Lifetime Alighnment and shim kit. The Dealer Service Manager gave me his card to have Firestone call him if they found a defect and he would send someone to verify.
