Hey , so im sure alot of you guys have read my other posts about the way my car handles on the freeway. Well i just noticed today that the inside an outside row of tread on the stock tires are starting to cup. What would cause this. This is both right and left side front only. Its only on the inner and outer edge of tread. I Know cupping can be caused by worn out struts, unbalanced tires. But what else could cause this . Keep in mind my steering feels loose.The car will drift right and left on the freeway. And steering wheel is a little off center either right or left mostly right. What should i tell the dealer when i bring it in?
