Sudden Tire Wear Issue
New guy here looking for input on a sudden tire wear issue on my daughters 2008 Cobalt Sport. I had new tires installed a few months ago. After about 5000 miles both rear tires are worn down to the steel bands. Both tires show the same wear. Front tires still look new.
Normally this points to a suspension issue, but everything is still tight and solid. No broken springs, wheelbearings have no play or grinding, shocks seem ok. The car drives good with no strange noises or tracking issues. Since the car has 95,000 miles, I will probably go with new shocks springs and bearings anyway. The previous set of tires did not wear like this, and since the rear suspension is not adjustable (except for shims) I am at a loss for the sudden change.
One tire blew out and Discount Tire replaced it for free and even though it was obviously a wear issue. Could their be a bad batch of 205/50 R17 Pirelli? My daughter took the car for the first tire, I will take it back for the other one.
Anyway, thanks in advance for any ideas or comments.
