Breaking the Code: What is Tire Temperature Rating?
Tire temperature rating grades a correctly inflated tire's ability to resist and properly disperse heat. A tire temperature grade ranges from A to C, with C being the lowest possible score under federal regulations. A tire assigned with an A score means it runs the coolest while one graded C runs the hottest. This score helps determines the risk of potential deterioration when operating a tire in high temperatures. For instance, consistently driving in high temperatures on a C rated tire could potentially lead to blowouts.
