305 mm across the tread, a sidewall 25% of that — 76 mm — on a 16-inch rim. That puts the whole wheel at 22.0 inches tall.

What it needs to sit on

Rim widths are the approved range for this section, published by ETRTO and
the Tire and Rim Association. Section width is quoted on one measuring rim;
the 5 mm per half-inch is the industry rule of thumb, not a guarantee.
It mounts on a rim between 8.5" and 11" wide, and the tread follows the rim: roughly 5 mm of section width for every half-inch, so about 293 mm across at the narrow end and 318 mm at the wide one. Written the way lift kits and wheel wells are, it is a 22.0×12.0R16 — tall by wide, in inches.
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.
