THE TREAD STRIPPED OFF THE TIRE, BUT THE INNERTUBE REMAINED INTACT..IT STILL IT FULL OF AIR WITH NO TREAD ON IT. THE LOOSE TREAD BEAT THE UNDERSIDE OF THE WHEEL WELL, CAUSING SOME VISIBLE DAMAGE. THIS IS OBVIOUSELY A TIRE PROBLEM AND I THINK FIRESTONE SHOULD BE HELD RESPONSIBLE. *AK( DOT NUMBER: TIRE SIZE: P235 75R15 )
