This size, measured
These figures are derived from the three numbers, not entered by hand: it is the same arithmetic as the size equivalence calculator.
- Sidewall height
- 140.3 mm
- Overall diameter
- 763.1 mm · 30.04 in
- Circumference
- 2,397.3 mm · 94.38 in
- Revolutions per mile

- Section width
- 10.04 in
- Usable mounting width
- 7 to 9 in
Usable mounting width is a trade rule of thumb, roughly 70 to 90% of section width. It is not a standard. The exact range is whatever the manufacturer publishes for that model.
