> Your rear axle gear ratio is 3.909:1. That means that the prop shaft turns
3.9 revolutions for each wheel turn. The circumference of your tires is
approximately 1.90 meters (circa 75 inches). That means that your wheels will
turn 526 times per km, or 846 times per mile. Your prop shaft turns 3.9 times
those figures, thus 2050 per km or 3300 per mile.
