How do you find the circumference of a tire?
How do you find the circumference of a tire?
If you have the diameter measurement, multiply it by pi to find the circumference. For example, a wheel with a 10-inch diameter will have a circumference of 10 x 3.14, or 31.4 inches. To calculate using the radius, multiply the radius by 2 and then multiply that result by pi.
