69.1 inches
34.6 inches
138.2 inches
380.1 inches
The circumference of a tire with a diameter of 22 in can be calculated using the formula C = π * d, where d is the diameter of the tire.
C = π * 22 = 69.1 inches
Therefore, the circumference of a tire with a diameter of 22 in is 69.1 inches.
So the answer is: 69.1 inches.
