Looking at the list of numbers and letters on your tire's sidewall can be confusing. The important thing to know is each number and letter in the sequence have a specific meaning. The following breakdown is generally what each of those letters and numbers means:
- The first letter is the vehicle type for that tire. For example, "P" for passenger vehicle.
- The number following is the width of the tire, in millimeters, from one sidewall to another.
- After the slash mark is the tire's aspect, or height, ratio.
