Taking the Guess Work out of Tire Size Readings

On the sides of the tire, the tire size is shown by a series of numbers. Your standard passenger tire will have three "groups" of numbers next to each other, with the last number following a letter. The first 3 digit number is a measurement of the tire's width, known as section width, and it expresses this size in millimeters.

The second grouping of numbers is a little more complicated and represents the height of the side wall. The number is actually a percentage and is expressed as an aspect ratio. This means the side wall height is the numbered percentage of the width of the tire, and it's in millimeters.

The third important grouping expresses the size of the wheel diameter, but in inches. It will be followed by the letter R, which in this case stands for radial construction.
