Decoding Tire Code: Load Index, Speed Rating, and M+S Designation This week, we will examine the rest of the code. The tire performance index is displayed after the wheel diameter, and represents the tire’s load and speed ratings. In this case, the 93 load index represents 1,433 pounds, and the speed rating of V represents 149 mph. Letter. Max.

How to Read Speed Rating, Load Index & Service Descriptions When Z-speed rated tires were first introduced, they were thought to reflect the highest tire speed rating that would ever be required, in excess of 240 km/h or 149 mph. While Z-speed rated tires are capable of speeds in excess of 149 mph, how far above 149 mph was not identified. service description identifies the tire's load index and speed rating. Service descriptions are required on all speed rated (except for Z-speed rated) tires manufactured since 1991.

Speed ratings are determined via laboratory tests that simulate road performance at various speeds.emember that the speeds listed are test speeds and not recommended speeds. Speed ratings apply only to the tire itself, and not to a particular vehicle. Putting a tire rated for a certain speed on a vehicle does not mean that the vehicle can be safely operated at the tire's rated speed. 1  B-Up to 31 mph.

Speed Ratings In situations where tires having different top speed ratings are mixed on a vehicle, the maximum speed certification is limited to the top speed certification of the tire with the lowest speed rating. Speed ratings do not indicate how well a tire handles or corners. They only certify a tire's ability to withstand high speed. Speed ratings are indicated as follows: The speed rating is described on the tire sidewall. Many tire manufacturers currently include the speed symbol in the tire size description.

A Simple Explanation of Tire Speed Rating The higher the speed rating, the better control and handling you’ll have at higher speeds. The speed rating system was developed to help control the safe performance of tires at standardized speeds. A tire’s certified speed rating is given a letter from A to Z, ranging from 5 km/h (3mph) to above 300 km/h (186 mph). This rating system (see below) shows the top speed for which a tire is certified.
