Sidewall

235/75R16

235 mm across the tread, a sidewall 75% of that — 176 mm — on a 16-inch rim. That puts the whole wheel at 29.9 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 29.9×9.3R16 — tall by wide, in inches.

What goes wrong on this size

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

Same 16-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.
