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
- 123.8 mm
- Overall diameter
- 755.5 mm · 29.74 in
- Circumference
- 2,373.5 mm · 93.44 in
- Revolutions per mile
- 678 rev.
- Section width
- 10.83 in
- Usable mounting width
- 7.5 to 9.5 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.
