Used Car Tire For Sale

Tires have been standardized to meet certain requirements and a system of coding tires has been created to identify each tire, not only for its size but also for the type of tire and speed or load ratings.

Most tire dealerships will choose an adequate tire for a vehicle that they are performing installations on, but some will sell the best tire for the car based on their profit, not for what is truly best for the vehicle. Learning to understand the manufacturing code system is necessary for car owners who want to be sure that the tires they are buying are the best for their vehicle.

Automotive Tire Size Coding and What it Means

Imprinted into the sidewall of every tire is a code that describes the size, type and ratings of each tire. The general coding looks something like, P215 / 70 R14 82S though the individual numbers and letters will vary with size and type. The first letter, "P" signifies that it is a passenger car tire–if it were for a light truck it would be "LT". The next set of three numbers is the width of the tire in millimeters, so the larger the number, the larger the tire width.
