How to Calculate Tire Turns Per Mile
By
Mark Kennan
The diameter of a tire is the distance across
the tire through the center.
Since tires are circular, you can find the
circumference of the tire from the diameter.
The circumference represents the distance the
tire travels when it makes one revolution.
If you know the number of inches in a mile
and the circumference, you can find the number of times the wheel turns per
mile.
First, measure the diameter of the tire in
inches.
Secondly, multiply the diameter by pi, which
is approximately 3.1416, to find the tire circumference.
For example, if the tire has a 20 inch
diameter, multiply 20 by 3.1416 to get 62.83 inches.
Finally, divide 63,360 inches per mile by the
tire circumference to find the revolutions per mile.
Finishing the example, you would divide
63,360 by 62.83 to get 1,008.44 revolutions per mile.
