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
- 82 mm
- Overall diameter
- 595.8 mm · 23.46 in
- Circumference
- 1,871.8 mm · 73.69 in
- Revolutions per mile
- 860 rev.
- Section width
- 8.07 in
- Usable mounting width
- 5.5 to 7.5 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.
