Sidewall

315 mm across the tread, a sidewall 35% of that — 110 mm — on a 17-inch rim. That puts the whole wheel at 25.7 inches tall.

What it needs to sit on

i

It mounts on a rim between 8.5" and 11.5" wide, and the tread follows the rim: roughly 5 mm of section width for every half-inch, so about 300 mm across at the narrow end and 330 mm at the wide one. Written the way lift kits and wheel wells are, it is a 25.7×12.4R17 — tall by wide, in inches.

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.
