The ideal Ford Bronco Wheels Size ranges from 16×7 to 20×9 inches, depending on the trim and driving style. Most models, including the Big Bend, Badlands, Outer Banks, and Wildtrak, use a 6×139.7 bolt pattern, +55mm offset, and 93.1mm center bore for perfect fitment. Off-road enthusiasts prefer 17×8 or 17×9-inch wheels for better tire flex and traction, while daily drivers often choose 18×9 or 20×9-inch wheels for enhanced handling and style.

When you’ve got a beast like the Bronco, you can’t afford to guess. The search for the perfect Ford Bronco wheel size isn’t just a detail – it’s the first step to truly unleashing its power. Whether you’re gearing up to dominate the most rugged trails or just ensuring a comfortable, durable ride on the road, dial in the wheel size first, and the rest will follow.

Quick Glance Over The Production Years of Ford Bronco

Ford Bronco OEM Specs: Essential Fitment Data

Bolt Pattern (PCD) & Centre Bore (CB)

The Bolt Pattern (PCD) dictates how many lugs the wheel has and the diameter of the circle they form. The Centre Bore (CB) is the diameter of the wheel’s center hole that sits on the hub.

Offset & Backspace (OEM Range)

Offset (ET) and Backspace are the dimensional specs that define how far the wheel sits relative to the hub mounting surface, crucial for clearance and stance.

[Note: For aftermarket custom wheels for Ford Bronco running large tires, a negative offset (e.g. -12mm to -25mm) is often necessary to push the wheel out and clear inner suspension components.]

Lug, Thread Size & Torque

[Note: 6th Generation uses 6 Lugs (except Raptor uses a 6×135 pattern), while 1st-5th Generation use 5 Lugs.]

Ford Bronco Wheels Size Overview

2021 – 2025 Ford Bronco 6th Gen

The 6th Generation introduced a massive variety of wheel sizes, ranging from 16″ to 18″, along with the dedicated Sasquatch Package featuring large 35″ tires on 17″ wheels. Since the factory specs have remained consistent across the model years (2021-2025) for these trim levels, the table is structured by trim.

1992 – 1996 Ford Bronco 5th Gen

The 5th Gen continued the use of 15-inch wheels, often available with different tire options depending on the trim package (Eddie Bauer, XLT, XL). The standard bolt pattern was 5×5.5″ (5×139.7mm).

1987 – 1991 Ford Bronco 4th Gen

The 4th Generation also primarily featured 15-inch wheels, maintaining the rugged, truck-based platform and the 5×5.5″ bolt pattern.

1980 – 1986 Ford Bronco 3rd Gen

The 3rd Generation (the first with the Twin Traction Beam front axle) primarily used 15-inch wheels. The optional tire sizes were the key differentiator in factory setup.

1978 – 1979 Ford Bronco 2nd Gen

The 2nd Generation was the first “Full-Size” Bronco, sharing components with the F-150. It came standard with large wheel wells, allowing for larger stock tires on 15-inch wheels.

1966 – 1977 Ford Bronco 1st Gen

The “Early Bronco” was compact and utilized smaller wheels and tires compared to later generations. They had a distinctive 5×5.5″ bolt pattern.

How to Select the Right Wheel Size for Your Ford Bronco?

Picking the right wheel size for your Ford Bronco isn’t just about looks – it’s about finding the perfect balance between performance, comfort, and durability. Whether you drive mostly on highways or spend weekends climbing muddy trails, here’s how to pick a size that actually works for your lifestyle.

1. Start With Your Driving Style
   If you’re an off-road fan, stick to 17” wheels. The smaller diameter leaves more room for a thicker tire sidewall, which gives you better traction, more cushioning over rocks, and extra protection against punctures. For daily commuting or city driving, 18-20 inch wheels offer sharper handling and a cleaner, more stylish street look.
2. Know Your Bronco’s OEM Specs
   Most modern Broncos use a 6×139.7 bolt pattern, a +55 offset, and a 93.1mm center bore. Staying close to these numbers ensures your wheels won’t cause rubbing, steering issues, or drivetrain stress.
3. Consider Tire Fitment and Clearance
   Bigger wheels often mean thinner tires, and thinner tires aren’t ideal for harsh trails. If you plan to run larger tires (like 33” or 35”), make sure your wheel width and offset allow proper clearance without hitting fenders or suspension components.
4. Think Long-Term Maintenance
   Off-road wheels need strong finishes and tougher construction. For daily driving, you should prioritize lightweight designs and smoother ride quality. When in doubt, choose the size that supports how you drive most – and make sure the setup works with your trim and tire plans.

Ford Bronco Tire Size Guide & Recommendations

Selecting the right tire size is the final, most critical step in transforming your Ford Bronco into an uncompromising off-road machine. This decision dictates everything from ground clearance to steering feel. Our recommendations focus on the current (6th Generation) Bronco, where the upgrade path is clearly defined by clearance and lift.

What Size Tire Should You Run? Here’s a quick checklist:

• 33-inch/35-inch: The most common upgrade. Typically manageable with a level kit or mild lift.
• 37-inch: Requires a serious lift (3+ inches) and high-clearance fenders/flares. This size demands aggressive offset for proper clearance.
• 40-inch+: Full custom suspension, high-clearance modifications, and major component changes are needed.

Consider These 3 Factors When Selecting Tire for Your Custom Wheel:

• Prioritize 17-Inch Wheels: For genuine off-road performance, a 17-inch wheel (like our VRT-601 Spartan or VRT-603 Atheno) is preferred. It allows for a maximum tire sidewall, which is critical for airing down on rocky terrain, providing cushion and optimal grip.
• Balance Aggression and Practicality: While 37-inch tires look phenomenal (especially with the deep concave of our VRD-703 Destroyer), remember the cost: they impact acceleration, braking, and fuel economy. The 35-inch tire on a lifted Bronco offers the best overall balance of aggression, affordability, and practical performance.
• Offset is Non-Negotiable: When running an aggressive tire (35-inch or larger), the correct negative offset is vital. Vortek designs our wheels to maximize the wheel track width for stability while managing the backspace to clear crucial suspension components. Don’t run a deep, wide tire on a high positive offset – it will rub internally.
