The tire speed ratings are used to tell drivers the top speed that a tire can go. Speed ratings are generally much higher than legal speed ratings.
The speed ratings describe the durability of the tire at high speed, higher rated tires are of more sound construction.
Tires have speed ratings. An S rated tire has a fixed rated speed of 112 mph. This is a good tire for a family sedan and van. A T rated tire with a speed rating of 118 mph is also a good choice for a family sedan or van.
