Lexus GX 550 biggest tire size: stock and lifted
The biggest tire owners run on a Lexus GX 550 at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
The Overtrail comes on 33-inch all-terrains and 18-inch wheels. On IH8MUD's LC250/GX550 tire thread, 265/70R18 fits with no problems and many owners run 275/70R18 (about 33.2 in) without mods. 285/70R18 is where rubbing starts. 35s generally need a level or small lift.
