Every tire is designed to withstand a specific level of speed over an extended period of time – think in terms of highway driving for example. The longer you drive at a certain speed, the more heat a tire will generate from the friction of that tire churning against the road surface and the side wall flexing.
A tire’s speed rating indicates the ability of that tire to handle a certain level of prolonged speed – and the heat it produces – without suffering deterioration in performance.
All tires in the in the U.S. are designed to maintain legal U.S. speed limits. A tire’s speed rating must match the maximum driving speed of the vehicle it’s mounted on. However, simply installing a tire rated for a designated speed does not mean the vehicle it’s mounted on can be driven safely at the tire’s highest performance level.
Below is a list of ratings coordinated with the speeds they represent. Note: These are not recommended speeds.

The load index is a numerical identifier assigned to each tire based on the ability of that tire’s size to withstand a certain load level of speed without deterioration in performance. The higher the load index value, the greater the load the tire can safely carry at the correct inflation.
Note: Pep Boys will only install tires that meet or exceed the original equipment manufacturers specifications for specific rating and load index.
