Wheel Size And Circumference - Garmin MARQ ATHLETE Owner's Manual

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.
