Front tires rub fender wells and sway bay. empty or loaded, more so when loaded. they rub the sway bar so bad that i cannot run a heavy lug tire. a heavy lug tire causes wheel lockup when steering is at full lock. this condition could result in loss of control and a crash. gm dealer has said that nothing else can be done and that i need to live with it, just to be careful when running a lug tire. *tr
