What it needs to sit on

i

It mounts on a rim between 8" and 10.5" wide, and the tread follows the rim: roughly 5 mm of section width for every half-inch, so about 273 mm across at the narrow end and 298 mm at the wide one. Written the way lift kits and wheel wells are, it is a 33.8×11.2R17 — 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.
