Join along as I work through making the necessary clearance mods for 35x12.5R20s tires on my LX. These Toyo AT3s spec out to be 34.5" x 12.5". If you have any suggestions, I'm interested in hearing.
Note that this fitment is specific to the LX as it's easier to fit larger and wider tires without the constraints of the KDSS bar on the LC. Not that it couldn't be done (some have), but I'll let another thread address those specifics.
Basic requirements for fitting a tire such as this would be proper offset. I'm using 1" spacers with my stock wheels for an effective offset of approximately +35mm. Offset gets more critical with larger tires and I would recommend offsets between +30 to +35 to minimize mods necessary to make such a fitment work. This offset will put my mild Toyo tires into the fender lip at full stuff so +25 offsets are going to be more difficult. Narrow tires can be made to work more easily as others have proven.
Areas to address are primarily at the front axle
1) Forward of front wheel, liner
2) Aft of front wheel, remove splash guard
3) Aft of front wheel, sidestep and liner
4) Aft of front wheel, body mount
5) Spare tire
Rear axle
1) Roll fender lip
Additional potential rub areas if fitting more aggressive tires
- Sway bar
- UCA
Other recommend mods to support large diameter tires
- Re-gear for 6-speed
- Upgraded brakes (Tundra BBK)
35s in combination with AHC lift, and a mild .75" sensor lift puts things way up in the air at almost ~5.0" higher step in height, or total lift. With another .75" boost into extra high if AHC detects a stuck. Fenders measurements from ground are 38.25" front and 39.5" rear. Thank goodness AHC also lowers to keep daily functionality of loading people and gear reasonable.

Hopefully this helps the next guy either fitting big tires or those with aggressive offsets. The 200-series has some pretty beefy fender lips so I'll start by saying what's here will buy limited more clearance. Real clearance may require cutting the fender lip or getting more aggressive. I'm...
