Ford Bronco Wheel Bolt Pattern
Direct Answer
The wheel bolt pattern for the current sixth-generation Ford Bronco (2021 model year and newer, including 2022, 2023, 2024, and 2025 examples) is 6x139.7 millimeters. This measurement is also expressed as 6x5.5 inches. The qualification that materially changes this answer is the Bronco Sport, which is a separate unibody crossover platform and does not use the 6x139.7 pattern. The older Bronco II also used a different specification.
Sixth-Generation Bronco Bolt Pattern Details
The 6x139.7 bolt pattern means the wheel has six lug holes arranged on a circle with a diameter of 139.7 millimeters. This is the same bolt circle used by many midsize trucks and SUVs, which broadens wheel compatibility for owners. The stock wheel diameter and width vary by trim level and package, but the bolt pattern remains consistent across the full-size Bronco range for the current generation.
Full-size Bronco (2021-2025) wheel fitment summary; Bolt pattern | 6x139.7 mm (6x5.5 in); Lug count | 6; Thread pitch | M14 x 1.5; Center bore | 93.1 mm; Typical stock wheel diameter | 16 to 18 inches depending on trim
Model Year and Variant Differences
For the 2022, 2023, 2024, and 2025 Ford Bronco model years, the wheel bolt pattern remains 6x139.7 millimeters across two-door and four-door body styles. Engine choice, whether the 2.3-liter EcoBoost four-cylinder or the 2.7-liter or 3.0-liter V6, does not change the wheel bolt circle. Trim levels from Base through Raptor share the same bolt pattern, though Raptor models use wider wheels and may have different offset specifications.
Bronco Sport Bolt Pattern
The Ford Bronco Sport is built on a car-based platform shared with the Escape and uses a 5x108 millimeter bolt pattern. Wheels from a full-size Bronco with a 6x139.7 pattern will not fit a Bronco Sport, and Bronco Sport wheels will not fit a full-size Bronco. The two vehicles share naming and styling cues but have no wheel fitment commonality.
Bronco II Bolt Pattern
The Bronco II, produced from 1984 through 1990, uses a 5x114.3 millimeter bolt pattern. This is a five-lug configuration that is distinct from both the current full-size Bronco and the Bronco Sport. Owners of a Bronco II should not assume that wheels listed for a modern Bronco will fit their vehicle.
Why the Bolt Pattern Matters
The bolt pattern determines which aftermarket or take-off wheels can be safely mounted to the vehicle. Using a wheel with the wrong bolt circle will prevent proper lug nut seating and can cause vibration, stud damage, or wheel separation. Center bore and lug nut seat type are additional fitment factors to verify when selecting replacement wheels.
Practical Guidance for Buyers
When shopping for wheels for a current full-size Bronco, confirm three specifications: the 6x139.7 bolt pattern, the 93.1 mm center bore, and the M14 x 1.5 lug nut thread. Many wheels designed for vehicles like the Toyota Tacoma, 4Runner, or Chevrolet Colorado share the 6x139.7 bolt circle but may require hub-centric rings or different lug nuts to fit a Bronco correctly.
Uncertainty and Verification
The specifications provided here reflect common manufacturer documentation and industry wheel fitment databases for North American market vehicles. Regional variations or special edition models could introduce exceptions. Before purchasing wheels, verify the bolt pattern stamped or cast into the back of an existing wheel or consult the vehicle's owner manual for the exact specification for your specific VIN.
