Sidewall

235/70R17.5

235 mm across the tread, a sidewall 70% of that — 165 mm — on a 17.5-inch rim. That puts the whole wheel at 30.5 inches tall.

What it needs to sit on

i

It mounts on a rim between 6.5" and 8.5" wide, and the tread follows the rim: roughly 5 mm of section width for every half-inch, so about 225 mm across at the narrow end and 245 mm at the wide one. Written the way lift kits and wheel wells are, it is a 30.5×9.3R17.5 — tall by wide, in inches.

What goes wrong on this size

i

2 drivers have filed a complaint. 0 of them ended in a crash, and nobody was hurt. Nobody died.

Where the wheel is named, 2 of 2 were on the front — the end that steers.

What fits instead

i

Same 17.5-inch rim, height within 3%. Past that the speedometer starts lying and things begin to rub.

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.
