Sidewall

265/70R18

265 mm across the tread, a sidewall 70% of that — 186 mm — on a 18-inch rim. That puts the whole wheel at 32.6 inches tall.

What it needs to sit on

i

It mounts on a rim between 7.5" and 9.5" wide, and the tread follows the rim: roughly 5 mm of section width for every half-inch, so about 255 mm across at the narrow end and 275 mm at the wide one. Written the way lift kits and wheel wells are, it is a 32.6×10.4R18 — tall by wide, in inches.

What goes wrong on this size

i

20 drivers have filed a complaint. 1 of them ended in a crash, hurting 5 people. Nobody died.

16 of them name what let go, and it is most often tread separation. Goodyear is named more than any other brand.

What fits instead

i

Same 18-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.
