Tire Markings Explained

All of the markings on the sidewall of a tire might seem confusing. However, many simply apply to the size of the tire. The first letter designates whether the tire is for a passenger car, “P,” a light truck “LT” or another type of vehicle. The number that follows the letter is the width of the tire measured in millimeters. The next number represents the sidewall height. The next letter is the speed rating, which means the top speed that the tire can handle. An “R” after the number tells you the tire is a radial.

The type of tire is followed by a number that represents the wheel diameter in inches. The next number indicates the load capacity of the tire followed by another speed rating.
