While this should be the exact diameter, the actual diameter can vary from this due to tire pressure, manufacturing tolerances, etc. So the only way to know the exact diameter is to physically measuring it. This can be done by stretching a string around the tire then measure the length of the string, or by marking the tire and the surface it's sitting on at the contact point, then rotate the tire several times. Measure the distance and divide by the number of rotations. Making more than one rotation lessens the chance of an error. | While this should be the exact diameter, the actual diameter can vary from this due to tire pressure, manufacturing tolerances, etc. So the only way to know the exact diameter is to physically measuring it.
