What Is Meant by Speed Rating? The speed rating of a tire indicates the speed category (or range of speeds) at which the tire can carry a load under specified service conditions. The speed rating system used today was developed in Europe in response to the need to control the safe performance of tires at standardized speeds.
The U.S. Department of Transportation (DOT) set the ratings scale, shown below. 1  But tire makers test their own tires and assign their own speed ratings. On the sidewall of every tire, you'll find one of these speed rating codes: 2  M - Up to 81 mph. 3  N - Up to 87 mph. 4  P - Up to 93 mph. 5  Q - Up to 99 mph. 6  R - Up to 106 mph. 7  S - Up to 112 mph.
