Lexus LX 450 biggest tire size: stock and lifted
The biggest tire owners run on a Lexus LX 450 at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
The stock size is 275/70R16. On a stock-height 80 Series or LX 450 with healthy springs, the usual answer is 285/75R16, about 33 in. Owners report it works, with some rubbing possible at full flex or full lock. Anything bigger starts rubbing. Slee's guide notes that 35s are possible with a 2-in Old Man Emu lift, but expect to rub when crawling unless you lower the bump stops.

Lift kits, wheels and tires for the Lexus LX 450
A mild lift with better shocks gets you on 33s without rubbing. Adjustable rear links and caster plates keep the geometry right as you go taller.
A real front bumper carries a winch and protects the radiator. A rear bumper with a swing-out carrier lifts a full-size spare off the ground.
Do you need to re-gear?
The 1FZ-FE trucks come with 4.11 gears. Slee suggests regearing to 4.56, 4.88 or 5.29 when you go up in tire size. Opinions vary on the right ratio, so its advice is to drive a truck with the setup you're considering first.
Fitment comes from owners and specialists; wheel width, offset, trimming and bump stops change what fits. Check clearance at full lock and full flex before you buy. Some links are affiliate links.
