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
- 172.3 mm
- Overall diameter
- 801.7 mm · 31.56 in
- Circumference
- 2,518.6 mm · 99.16 in
- Revolutions per mile
- 639 rev.
- Section width
- 10.43 in
- Usable mounting width
- 7.5 to 9.5 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.
