How to Read your Tire Size
You can determine your tire size by three simple methods. First is your owner’s manual, secondly is by Height, Section Width, and Rim Diameter as shown below in
example #1 below, and thirdly is by example #2 below with tires having metric numerical markings on the sidewall. The tire size branded on the sidewall provides a significant amount of information about the tire's intended purpose, dimensions, load capacity and high temperature/high speed durability. This information is necessary to assure accuracy in providing you correct tire fitment.
The overall height of the tire when mounted and inflated to recommended air pressure. In this example the tire is 24 inches tall.
The diameter of the wheel that this tire will mount to. In this case it will be a 12-inch diameter wheel.
Tire Section width
The overall width of the tire when mounted and inflated to reccommended air pressure. In this example the tire is 11 inches wide.
