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
- 704.7 mm · 27.74 in
- Circumference
- 2,213.9 mm · 87.16 in
- Revolutions per mile
- 727 rev.
- Section width
- 8.86 in
- Usable mounting width
- 6 to 8 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.
Equivalent sizes
Sizes whose overall diameter stays within 3% of this one. The ones we carry link to their own page. These are computed suggestions, not a guarantee of fit: the vehicle manual decides.
