Problem: How to measure tires
Check the tire's sidewall to read its wheel diameter.
The wheel diameter is often, though not always, printed on the tire's sidewall. You will be able to spot the diameter number by looking for the number followed after a capitalized " r. "
The tire diameter may be printed in inches or meters, depending on your country.
