Tire Ratings Chart - Load Index and Speed Ratings

TIRE LOAD INDEX & SPEED RATINGS Your tire's load index tells you P205 / 55R16 91T its maximum carrying capacity, while speed rating indicates the range of speeds at which the tire Load Index Speed Rating. can carry a load. Load and speed ratings should be looked at P205108 together when choosing a tire.

(O Typically, the load indexes of the tires used on passenger cars and light trucks range from 70 to 110. O EXAMPLE: A load index of 92 can support 1,389 pounds at maximum air pressure. Multiply that by 4 tires (4 x 1,389 = 5,556 pounds) to get your maximum load-carrying capacity SPEED RATINGS Max.

Speed ratings apply only to the tire, not to the vehicle. Putting a speed rated tire on any car does not mean the car ean be operated at the tire's rated speed. (O The Tire Industry Safety Council bulletin says: "A reasonable person realizes that driving speeds are dictated by many factors, particularly such things as the weather, road surface and mechanical condition of the vehicle. These symbols do not mean that motorists can drive safely at the maximum speed for which the tire is rated or in excess of the posted speed limits." catalog Pruck Accessori
