Speedometer Calibration:
There are two factors that affect your speedometer reading; actual tire diameter and axle gear
ratio. The actual tire diameter is usually different than what is printed on the side wall of your tire. For example: A 33 x 11.5
x 15 tire (depending on the brand), may actually measure 32.5" in diameter. Tire sizes vary greatly among the suppliers. Even
the same tire from the same manufacturer can vary as much as 7% in diameter.
