Except where limited by maximum speed, the speeds [mph (kph)] shown below were calculated with the following formula:

R * 60 * 3.14159 * (W * P / 100 * 2 / 25.4 + D) / 12 / 5280 / G
R = RPM of engine [6750 redline assumed]
W = Width of tire
P = Profile (aspect ratio) of tire
D = Diameter of wheel
G = Gear Ratio
