Ford Bronco Wheel Fitment Guide

The wheel sizes you can fit depend on your Bronco's trim level. For most 6G Broncos, the bolt pattern is 6×139.7mm with a 93.1mm bore (except the Raptor which has a 6×135mm pattern). Base models come with 16×7 +55 wheels, while trims like Big Bend and Black Diamond feature 17×7.5 +55 wheels. At Hardrock Offroad, we offer multiple fitment options that work perfectly with your Bronco. For stock suspension, we recommend our 17×9 wheels with +1 or -12 offset, or our 20×9/20×10 options for a more aggressive stance. Check our fitment guide for the exact specifications that will work with your particular Bronco trim and suspension setup.

Offset is the distance between your wheel's mounting surface and its centerline, measured in millimeters. Positive offset places the mounting surface toward the outside of the wheel, while negative offset pushes it inward. Backspacing measures from the mounting surface to the back edge of the wheel. Both measurements are crucial for proper fitment on your Bronco. The wrong offset can cause rubbing against fenders or suspension components, especially at full steering lock. One common issue Bronco owners face is interference with OEM crash bars. At Hardrock Offroad, we've done extensive R&D to determine the perfect offsets for each Bronco configuration, ensuring our wheels give you the right stance without clearance problems.

Yes, you can fit 35-inch tires on certain stock Broncos. If you have a Sasquatch package, Wildtrak, or Everglades model, your Bronco already comes with 35-inch tires (315/70R17). For other trims without these packages, fitting 35-inch tires may require slight modifications. The Base model might need a 2-inch lift, while Big Bend, Black Diamond, and Outer Banks can accommodate 35-inch tires without suspension changes in some cases. At Hardrock Offroad, we offer wheel options specifically designed to work with 35-inch tires on various Bronco configurations, including our H105-H109 series in 17×9 and numerous 20-inch options that pair perfectly with these larger tires.

Not necessarily, but it depends on how big you want to go. For 33-inch tires, most Bronco trims won't need any lift. For 35-inch tires, Base models typically need at least a 2-inch lift, while other trims might be able to fit them without lifting. If you're looking to go to 37-inch tires or larger, we definitely recommend a lift kit of at least 2.5 inches. At Hardrock Offroad, we have wheel fitments designed specifically for different suspension setups, including stock, leveling kits, and 2.5"+ lift kits. Our fitment guide breaks down exactly which wheel and tire combinations work best for each setup, so you'll know exactly what you need for your build.

For serious off-roading, 17-inch wheels are generally the sweet spot. They allow for tires with more sidewall, providing better traction, absorption, and durability on rough terrain. Our 17×9 wheels in either +1 or -12 offset are extremely popular for trail-focused Broncos. They pair perfectly with 33" to 35" tires like the 285/70R17 or 315/70R17. That said, many of our customers successfully off-road with our 20-inch wheel options too, especially with the right tire choice. For rock crawling, stick with 17s, but if you split time between trails and pavement, our 20-inch wheels offer a great balance of off-road capability and on-road performance.

Yes, changing wheel width definitely affects handling. Wider wheels generally offer more stability and improved cornering on-road, while also providing a wider footprint for better traction off-road. However, going too wide can affect your "scrub radius," which impacts steering feel, stability, and tire wear. When you increase width, you need to pay attention to offset to ensure proper fitment. At Hardrock Offroad, we've carefully engineered our wheel fitments to optimize handling both on and off the trail. Our most popular width for Broncos is 9 inches, which provides an excellent balance of improved performance without negatively affecting handling characteristics or causing clearance issues with stock components.
