Before you ask if X size tire can fit...
The largest tire size you can fit with *no modification* is 265/70/17. If you're willing to make some adjustments, the largest tire you can fit with *no lift* is 285/70/17. This will require a body mount chop and fender liner massaging with heat gun and maybe a knife.
Max spare tire size in stock location is about 32“ at stock ride height. With taller rear lift it might be possible to fit larger spare since the axle would move forward. It still not a good idea with out running extended bump stop since it might be hitting the spare during full compression.

| 265/65/17 | Nokian Rotiiva AT | 17×7.5 | 30 | OEM GX470 | GX470 Stock backspacing is 125 mm No fitment issues. No rubbing. | Lee K. Shuster |
| 265/70/17 | Falken AT3W E | 17×7.0 | 15 | Toyota factory p/n 42611-35520 (4Runner, 6-spoke, all silver) | Note that newer Toyota factory 4Runner wheels are .5” in narrower and have 15 mm less Offset compared to stock GX470 wheels. Consequently, stance (outward poke of tire) is increased by about 15 mm, but within stock fender lines. Original Lexus center caps will not fit these wheels. The wheel well gap is filled by an extra 13 mm. The speedometer now reads 3% slow. Traveling an actual 60 mph the speedometer reads 58 mph. No fitment issues. No rubbing. Mild appearance upgrade, stiffer/taller 10 ply sidewalls, and improved tire load rating. | Lee K. Shuster |
