So they say you shouldnt patch z rated tires. Is this because of liability reasons for tires that are designed to reach speeds in excess of 149mph or does it have something to do with the construction of the tire and it not holding air with a patch? And please no dumb asses who respond with just a Youre not supposed to patch z rated tires cause Ive already heard that before I want to know why you arent supposed to patch them.
