Ford Bronco II biggest tire size: stock and lifted
The biggest tire owners run on a Ford Bronco II at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
Stock was 205/75R15, about 27 inches tall. The Ranger Station shows a stock-height Bronco II on 31x10.50R15s with trimmed fenders, and its rule of thumb is that 31s need about 1.5 inches of lift plus fender trimming. 32x11.50R15s have fitted on a 1.5-inch lift with the bottom rear corner of the front fender trimmed. Remember that the Dana 28 front axle is rated for about 31-inch tires.
Biggest Ford Bronco II tire at every lift
| LIFT | BIGGEST TIRE | WHAT IT TAKES |
|---|---|---|
| Stock | 31x10.50R15 | Shown on The Ranger Station with no lift and trimmed fenders. Its rule of thumb pairs 31s with about 1.5 in of lift plus trimming. The Dana 28 front axle is rated for about 31 in tires. |
| 1.5 in | 32x11.50R15 | Fits with the bottom rear corner of the front fender trimmed. |
| 4 in | 31–32 in (33 in with cut-out flares or a 3 in body lift) | The Ranger Station's chart: 31s fit, 32s need trimming, and 33s need cut-out flares or a 3 in body lift. |
| 6 in | 33 in (35 in with a 2–3 in body lift and cut-out flares) | 35s also show up on 3–5.5 in lifts with body lifts and cut-out flares, and on solid-axle swaps. At this size, plan for a Dana 35 or a solid axle, an 8.8 rear and regearing. |

Lift kits, wheels and tires for the Ford Bronco II
TTB lifts use taller coils, drop brackets for the beam pivots and radius arms, a dropped pitman arm and rear add-a-leafs or blocks. The Ranger Station's builder guides name James Duff and Skyjacker, and warns against bolt-on drop plates for the passenger beam pivot.
The Dana 28 is good for about 31-inch tires, so builders swap in an Explorer Dana 35 TTB in front and often an Explorer 8.8 in the rear, then regear both to suit the tires.
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.
