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
- 105.8 mm
- Overall diameter
- 668.7 mm · 26.33 in
- Circumference
- 2,100.8 mm · 82.71 in
- Revolutions per mile
- 766 rev.
- Section width
- 9.25 in
- Usable mounting width
- 6.5 to 8.5 in
Usable mounting width is a shop 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.
