285/75R16 designates a tire 285 mm (11.2") wide with a sidewall 75% as tall as it is wide — about 214 mm (8.4") — mounted on a 16-inch wheel. That works out to an overall diameter of roughly 32.8", a circumference of about 103.1", and approximately 614 revolutions per mile. Exact figures vary slightly by manufacturer and tread design.
Of the 64 285/75R16 tire models we track, the most common category is all-terrain (55 models), followed by highway all-season truck (8) — a good indicator of the kind of vehicles and driving this size is designed for.
