Sidewall

245/40R19

245 mm across the tread, a sidewall 40% of that — 98 mm — on a 19-inch rim. That puts the whole wheel at 26.7 inches tall.

What it needs to sit on

i

It mounts on a rim between 7" and 9" wide, and the tread follows the rim: roughly 5 mm of section width for every half-inch, so about 235 mm across at the narrow end and 255 mm at the wide one. Written the way lift kits and wheel wells are, it is a 26.7×9.6R19 — tall by wide, in inches.

What fits instead

i

Same 19-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.
