Wheel Size and Circumference
Your speed sensor automatically detects your wheel size. If
necessary, you can manually enter your wheel circumference in
the speed sensor settings.
The tire size is marked on both sides of the tire. This is not a
comprehensive list. You can also measure the circumference of
your wheel or use one of the calculators available on the
internet.
