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 speed rating is described on the tire sidewall. Many tire manufacturers currently include the speed symbol in the tire size description. Example: P225/70 H R15 Speed Symbol. In this example the H indicates that the tire is capable of sustained speeds up to 130 MPH.ires certified for Z speed ratings (top speeds over 149 MPH) will continue to be identified by including the speed symbol in the size designation since the top speed for a Z rated tire is determined in accordance with the manufacturer's vehicle specifications.
