Tire circumference table

Tire circumference can be determined by either of the following two methods:
•
Measure the actual tire circumference (L)
After ensuring that the tire pressure is appropriate, sit on your
bike, roll it forward so that the tire makes one full revolution (use
the valve or other marking as a reference), and measure the dis-
tance traveled on the road.
•
Tire size chart
* The tire size or ETRTO code is indicated on the side of the tire.
