Tread depth is a vertical measurement between the top of the tread rubber to the bottom of the tire's deepest grooves. In the United States, tread depth is measured in 32nds of an inch. Because it is difficult to accurately measure tread depth with a ruler, tread depth is best measured with a...

Revolutions Per MileRevolutions per mile indicates the number of times a tire revolves while it covers the distance of one mile. Depending on the tire manufacturer, revolutions per mile may be either measured in a laboratory or derived from calculations based on their previous test experience....

What's the difference between the tire sizes of P225/60R16 and 225/60R16? The obvious answer is the "P" in front of the first size, but just what does the "P" stand for and what does it tell us about the tires? P-metric sized tires are the ones with the "P" at the beginning of the tire size,...

A tire's section width (also called "cross section width") is the measurement of the tire's width from its inner sidewall to its outer sidewall (excluding any protective ribs, decorations or raised letters) at the widest point. This measurement is made without any load placed upon the tire and...

Much like your foot can sometimes fit in a half size up or down shoe, tires have a range of rim widths they can be mounted on while still performing as designed. Likewise, similarly to how a person typically knows their "shoe size," tires have a measuring rim width from which the tire's specs...

Maximum LoadA tire's maximum load is the most weight the tire is designed to carry. Since a tire's load carrying capacity is related to the tire's size and construction and how much inflation pressure is actually used, maximum loads are rated with the tire inflated to an industry assigned...

Tires
A load index is an assigned numerical value that signifies a tire's maximum load carrying capacity. They're useful to help compare load carrying capacity of different-sized tires, and as you might expect, the higher the tire's load index number, the greater its load carrying capacity. Using the...

Overall Diameter
A tire's overall diameter is the outer diameter of the tire measured in the center of the tread. This measurement is made without any load placed upon the tire and after the tire has been properly mounted on its industry assigned measuring rim and has been inflated and reset...
