265/70R16 designates a tire 265 mm (10.4") wide with a sidewall 70% as tall as it is wide — about 186 mm (7.3") — mounted on a 16-inch wheel. That works out to an overall diameter of roughly 30.6", a circumference of about 96.2", and approximately 659 revolutions per mile. Exact figures vary slightly by manufacturer and tread design.
Of the 92 265/70R16 tire models we track, the most common category is all-terrain (45 models), followed by highway all-season truck (30) — a good indicator of the kind of vehicles and driving this size is designed for.
