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
167.8 mm
Overall diameter
843.5 mm · 33.21 in
Circumference

Section width

Usable mounting width
8.5 to 11 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.
