Hi.

The procedure is in the manual on page 17 - including a handy chart.

To cipher is simple:

32.6 x pi x 25.4 = circumference without weight on the tires.

Always Multiply that result by 0.97 to account for the "squish" caused by weight which will give you a good starting point. (3% squish is the common correction factor to begin with)

So - 2600.456 x 0.97 = 2522

Make sure your Gear Ratio is correct whenever you open the custom options menu! It might need to be changed.

If you can, fine tune it until the Edge's speed (not the speedometer) agrees with a GPS.
