33x10.50R15 · stock height

Fits, rubs some

33s are the max at stock height on a squarebody K10 — offset-dependent, with rub on hard hits.

Heads up: 33s are the documented stock-height ceiling on a K10; wheel offset and width decide how much they touch

35x12.50R15 · 4″+ lift

Fits, rubs some

35s fit a squarebody on a 4" lift with occasional rub at speed — 6" of lift is the no-contact recipe.

Heads up: Works on 4" but can rub on hard hits with stock springs — 6" is the clean height; plan 4.10 gears for 35s
