The Secrets of Tire Numbers (Part 1)

Today, we are going to let you know about the the secrets of tire numbers we are introducing how we can read numbers on your tire to figureout the size of the tire.

TIRE SIZE

Example: P225/50/R17 98H

P identifies your tire as a Passenger Tire. The P stands for PMetric. If your tire size starts with LT rather than a P than it identifies the tire as a Light Truck tire.

225 identifies the tire section width, which is the measurement of the tire from sidewall to sidewall in millimeters. This measurement varies depending on the rim to which it is fitted.

(There are 25.4 millimeters per 1 inch.)

50 is the two-figure aspect ratio. This percentage compares the tire's section height with the tire's section width. For example, this aspect ratio of 50 means that the tire's section height is 50% of the tire's section width.

R indicates the construction used within the tires casing. R stands for radial construction. B means belted bias and D stands for diagonal bias construction.

17 The last dimension listed in the size is the diameter of the wheel rim, which is most often measured in inches.
