Tire sizes by height
What size is a 32-inch tire?
A 32-inch tire is about 32 inches tall. In flotation sizing it is written 32x11.50 and 32x9.50 (followed by the wheel size, e.g. 32x9.50R15). Common metric sizes within half an inch of 32 in are 255/70R18 (32.1 in), 255/75R17 (32.1 in), 275/65R18 (32.1 in), 275/55R20 (31.9 in), 285/45R22 (32.1 in) and 275/70R17 (32.2 in). Real tires differ a little by model, so check the maker's published diameter.

FAQ
What size is a 32 inch tire in metric?
A 32-inch tire is about 32 inches tall. In flotation sizing it is written 32x11.50 and 32x9.50 (followed by the wheel size, e.g. 32x9.50R15). Common metric sizes within half an inch of 32 in are 255/70R18 (32.1 in), 255/75R17 (32.1 in), 275/65R18 (32.1 in), 275/55R20 (31.9 in), 285/45R22 (32.1 in) and 275/70R17 (32.2 in).
Are all 32-inch tires exactly 32 inches tall?
No. The number is nominal. Maker data books list real 32-inch flotation tires a little under or over 32 in (often 0.5–1.5% under), and metric sizes near 32 in vary too. Compare published diameters before mixing sizes.

Important: These are calculated (nominal) dimensions, not a fitment recommendation. Real tires of the same size differ by brand and model (makers allow about ±3% of section height), and width changes with the rim it is mounted on. The math can't see wheel width and offset, clearance at full steering lock and suspension travel, load index, speed rating, or what your vehicle maker approves. Before changing size, check your door-jamb placard and owner's manual and ask a tire professional. A replacement tire must meet or exceed the load index and speed rating on the placard.
