Converting Metric to Inches

There are two ways that tire manufacturers display tire size, inches and metric. How to read tire size in inches is very straight forward. Example A : 33X12.50R15 The first number is your overall diameter of the tire. In this example the tire diameter or "height" is 33 inches tall. The second number represents the width of the tire. In most cases with inch measurement tires the width will have a .50 decimal after the initial number. In example "A" this reads 12.50, meaning the tire width is 12 and 1/2 inches. The final number simply is the wheel size or "diameter" of the wheel that the tire will fit on.

How to read tire size with a metric measurement is a little more difficult and usually takes a calculator to get exactly right.

how to read tire size

Example B : 285/75R16

On metric tires the first number is your width of the tire in millimeters. In example "B" this reads 285mm. There are 25.4 mm in one inch. To convert 285mm to inches you divide 285 by 25.4 to get 11.22". So the width of a 285mm tire is 11.22". The next number represents the percentage of the width (285mm or 11.22") that is the sidewall height of the tire. In this example the side wall height of the tire would be 75% of 11.22" which is 8.41" or 214mm. To then get the overall diameter of the tire you would add the two sidewalls measurements and the diameter of the wheel. In example "B" the last number "16" is the wheel size the tire will fit on. Therefore the sidewall twice would be 8.41 x 2 = 16.82 plus the wheel "16" makes the tire height 16.82 + 16 = 32.82. So a 285/75R16 metric tire would calculate to an inch measurement tire of 32.82X11.22R16. Remember, not all tire sizes are manufactured in both metric and inch sizes so learning how to read tire size can be a valuable tool for anyone in the market for new tires.
