345/60R22

345 mm across the tread, a sidewall 60% of that — 207 mm — on a 22-inch rim. That puts the whole wheel at 38.3 inches tall.

It mounts on a rim between 9.5" and 12.5" wide, and the tread follows the rim: roughly 5 mm of section width for every half-inch, so about 330 mm across at the narrow end and 360 mm at the wide one. Written the way lift kits and wheel wells are, it is a 38.3×13.6R22 — tall by wide, in inches.

Same 22-inch rim, height within 3%. Past that the speedometer starts lying and things begin to rub.

Same height, different rim

Bigger rim, same overall height. Sharper steering, harsher ride, and far less rubber between your wheel and the next pothole.

If you fit something taller

A taller tire covers more ground per turn, so the needle reads low and the odometer counts short. Over ten thousand miles on the dial, the last column is what you really drove.
