How to Read and Understand Tire Sizes

How do we know what size to ask for when it comes time to replace our old, worn tires? The answer can be found printed on the exterior sidewall of your old tires.

The width of a tire is measured in millimeters and the first number you will see indicates tire width, for example, a tire size of P215/65 R15 has a width of 215 millimeters. the "P" indicates that the tire is approved for a standard passenger car.

The second number indicates the aspect ratio, or the ratio of the sidewall height to its width and the "R" indicates that the tire is of radial construction. Radial tires are made with layers of fabric, the fibers of which run at crisscrossing right angles to each other for better grip and handling.

Knowing how to read your tire size will help save you time and frustration in the end. For more information on how to read and understand tire sizes contact our service center today!
