When the topic turns to serious off-road capability for the seventh-generation Ford Bronco, the conversation inevitably circles back to one specific modification: the Sasquatch package. More than just a trim level, the Sasquatch represents the factory blueprint for building a trail-destroying machine, and the foundation of that setup is its tires. Understanding the specific rubber fitted to this legendary configuration is essential for anyone looking to replicate its performance or upgrade their own build.
The Legacy of the Sasquatch Package
Introduced for the 2021 model year, the Sasquatch package was designed to bridge the gap between the base 2-door Bronco and the high-rolling Rubicon. It was never just about looks; it was a carefully engineered off-road system delivered in a relatively accessible package. At the heart of this system were massive 37-inch all-terrain tires mounted on 17-inch wide alloy wheels, paired with unique front and rear axle differentials that allowed for greater wheel articulation. This combination transformed the Bronco from a recreational weekend toy into a legitimate overlanding and rock-crawling platform right from the factory.
Factory Tire Specifications and Engineering
Ford partnered with BF Goodrich to develop the specific tire for this application, resulting in the BF Goodrich All-Terrain T/A KO2. Measuring at 37 inches tall, 12.5 inches wide, and mounted on a 17-inch bead seat, these tires were chosen for their specific geometry. The aggressive tread pattern features tightly spaced side lugs for stability during high-speed desert runs and widely spaced outer lugs with self-cleaning geometry to shed mud and debris in swampy conditions. The dual-density rubber compound provides a firm base for on-road stability while remaining supple enough to conform to rocks and roots for superior traction off-camber.
Performance Advantages in the Field
The height advantage provided by the 37-inch footprint is the most immediate benefit, translating to increased breakover and departure angles. This added ground clearance allows the Bronco to traverse jagged terrain without undercarriage damage, a critical factor for remote expeditions. The wider stance enhances lateral grip during high-speed cornering on gravel and provides the floatation necessary to traverse loose surfaces like sand and snow that would cause a standard tire to sink. This blend of size and tread design makes the Sasquatch setup remarkably versatile, handling everything from highway driving to technical mountain trails with competence.
Aftermarket Considerations and Modern Alternatives
For current Bronco owners, the quest for Sasquatch-level performance often leads to the aftermarket. While 37-inch tires remain the standard reference point, many builders now opt for 38-inch variants to gain even more height, utilizing a lift kit to accommodate the larger rubber. When selecting a replacement tire, the BF Goodrich KO2 remains a top-tier recommendation due to its durability and predictable wear characteristics. However, alternatives from manufacturers like Nitto, General Tire, and MTR offer different tread compounds and block shapes that can fine-tune the balance between on-road comfort and off-road aggression to better suit specific driving styles.
Wheel and Fitment Requirements
It is critical to understand that simply placing a larger tire on a stock wheel is not feasible. The Bronco Sasquatch wheels feature a 17-inch diameter with specific backspacing and offset measurements designed to position the tire correctly within the fender wells. Upgrading requires either purchasing used OEM Sasquatch wheels or selecting aftermarket wheels that match the correct diameter, width, and offset. Failure to match these specifications can result in rubbing against the suspension components or fenders, particularly when the vehicle articulates over obstacles or during sharp turns.
