6th Gen Ford Bronco biggest tire size: stock and lifted
The biggest tire owners run on a Ford Bronco (sixth generation) at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
On stock wheels and suspension, a 285/75R17 (about 33.8 in) with no rubbing reported. Narrow 35s (35x10.50R17 or 35x11.50R17) fit factory 17s once the front crash bars are removed, usually with a small level of 1.25–1.5 in. Full-width 35x12.50R17s need about +30 mm wheels, high-clearance flares and roughly 1.5–2 in of lift. The factory way to get 35s is the Sasquatch package (315/70R17); the Raptor runs 37s.

Lift kits, wheels and tires for the 6th Gen Ford Bronco
A 1.25–2-inch level makes room for 35s on non-Sasquatch trucks. Bigger lifts need attention to CV angles and steering.
Wheels with about +30 mm offset clear full-width 35s, and 4.46 or 4.7 gears restore the Sasquatch's gearing.
The factory skid plates cover the essentials. A steel bumper, rock rails and extra skids are what you add before the rocks find the rest.
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.
