66-77 Ford Bronco Wheels, Hubcaps, & Accessories

The early Ford Bronco uses a 5x5.5 (5x139.7mm) bolt pattern with a standard 15-inch wheel diameter. Factory wheel width was 5.5 or 6 inches, but most builds upgrade to 8,9 or 10" wide wheels for better tire support and stance. Tom's Offroad carries steel wheels in both factory and custom widths, as well as modern off-road wheels that fit the early Bronco's bolt pattern. Many builders are opting to upgrade to 17" wheels for more tire options as well.

Factory-style steel wheels are heavier but more durable against rock impacts and are preferred for serious off-road use and period-correct restorations. Generally, aftermarket alloy wheels are lighter, improving acceleration and unsprung weight, and offer more design variety. For trail builds, beadlock-capable steel or alloy wheels are popular additions when airing down tires significantly on rough terrain.

A 15x8 wheel with 3.75 inches of backspacing is the most common fitment for early Broncos running a mild lift and 33-inch tires, providing a slight outward offset that fills the fender well without rubbing. Running less backspacing pushes the tire outboard and may require flares. More backspacing tucks the tire in for a cleaner look but can reduce clearance against the inner fender on full suspension compression. Obviously, there are so many factors that will determine what offset is right for your build, such as cut or uncut rear fenders, tire width, how you prefer the tire to sit (pushed out or sucked in), brake clearance, other sheetmetal clearance and others.

Yes, many modern off-road wheel manufacturers offer wheels in 5x5.5 bolt pattern with appropriate backspacing for early Bronco fitment. Brands like Method, KMC, and American Racing all have 5x5.5 options. Confirm the wheel's center bore matches the early Bronco's hub diameter or use hub-centric rings for a vibration-free fit at highway speeds.

The early Ford Bronco has a hub center bore of approximately 3.27 inches (83mm). When selecting aftermarket wheels, choose a wheel with a center bore that matches or exceeds this diameter. If the wheel's bore is larger than the hub, use machined hub-centric rings to fill the gap and prevent vibration.
