Assuming the tire is a typical radial tire, the tire diameter can be calculated as follows:
First, convert the rim diameter from inches to centimeters, since tire measurements are typically given in metric units:
17 inches = 43.18 cm
Next, convert the tire height from inches to centimeters:
5.2 inches = 13.21 cm
The tire diameter is then calculated as follows:
Tire diameter = 2 x (tire height) + rim diameter
Tire diameter = 2 x 13.21 cm + 43.18 cm
Tire diameter = 69.6 cm
Therefore, the tire diameter is approximately 69.6 cm.
