265/65R17 designates a tire 265 mm (10.4") wide with a sidewall 65% as tall as it is wide — about 172 mm (6.8") — mounted on a 17-inch wheel. That works out to an overall diameter of roughly 30.6", a circumference of about 96.0", and approximately 660 revolutions per mile. Exact figures vary slightly by manufacturer and tread design.
Of the 98 265/65R17 tire models we track, the most common category is all-terrain (46 models), followed by highway all-season truck (32) — a good indicator of the kind of vehicles and driving this size is designed for.
