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
- 117.5 mm
- Overall diameter
- 692.2 mm · 27.25 in
- Circumference
- 2,174.6 mm · 85.61 in
- Revolutions per mile
- 740 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.
