How many times does a tire with a diameter of 25 in. rotate when it travels a mile? **Tip: As there are 63,360 inches in each mile, 63,360 divided by circumference = number of full rotations. Round up to the next whole number.
A tire with a diameter of 25 in. has a circumference of approximately 78.54 in. (circumference = πd).
So, 63,360 inches in a mile divided by 78.54 inches in one full rotation equals approximately 807.5 full rotations.
Rounding up to the next whole number, the tire would rotate approximately 808 times when traveling one mile.
