To set the circumference for the type
of tires you are using, you can either
use the table below to obtain an
approximate tire circumference or
measure your actual tire circumference
by the rollout method.

1. Extend a tape measure out to
3000mm (120 inches) and lock
it in place.
2. With your tire inflated to its proper
pressure, place the valve at the
6:00 position (at the bottom) directly
over the start of the measuring tape.
3. Roll the wheel one complete
revolution until the valve stem is
again at the 6:00 position. Read the
tape directly under the valve and
note the distance in millimeters. (To
convert inches to millimeters, multi-
ply inches by 25.4). Use this num-
