The THRET Offroad 809 Radar is a cast aluminum wheel for the 2021, 2022, 2023, 2024, 2025, and 2026 Ford Bronco. THRET Offroad gravity-casts each wheel in one piece. The face uses a split five-spoke design. The wheel is drilled for the Bronco's factory 6x139.7 bolt pattern, so it bolts straight on with no adapters.

Five Finishes

The 809 Radar is listed here in five finishes. Satin Gray and Satin Silver are flat, low-shine finishes in lighter tones. Satin Black is a flat, low-shine black. Satin Black/Milled is a flat black with cut metal accents on the spokes. Superfinish comes in the 20x10 size.

Not every size comes in every finish. Pick your finish first. The size menu then shows only the sizes that finish comes in.

Sizes and Offsets

The 809 Radar comes in five size and offset combinations for the Bronco. The 17x8.5 comes with a -6mm or +6mm offset. The 18x9 and 20x9 each come with a +18mm offset. The 20x10 comes with a -12mm offset.

Every size in the menu lists three numbers. The first is the wheel size, such as 17x8.5. That means a 17-inch diameter and an 8.5-inch width. The second is the offset. The third is the backspacing.

What Offset and Backspacing Mean

Offset is the distance between the center of the wheel and the face that bolts to your hub. It is measured in millimeters. A negative offset, like -12mm, moves the wheel out toward the fender. A positive offset, like +18mm, pulls the wheel in toward the frame.

Backspacing is the distance from the mounting face to the inner edge of the wheel. It is measured in inches. The 809 Radar ranges from 4.5 inches to 5.7 inches of backspacing on the Bronco sizes. A lower backspacing number puts more of the wheel outside the hub. That gives a wider stance and more room between the tire and the suspension parts behind it.

A wider stance looks more aggressive, but it also moves the tire closer to the fender. Tire size, lift height, and your trim's fender flares all change how much room you have. Check those before you pick an offset.

Fitment

The 809 Radar uses the 6x139.7 bolt pattern that Ford uses on every 2021 through 2026 Bronco. The center bore is 106.1mm, which is larger than the Bronco hub. That means the lug nuts center the wheel on the hub. Hub-centric rings are an option if you want the hub to carry the centering job.

Each wheel carries a 2,500-pound load rating. The lug seat is a conical acorn and spline style. The wheel is DOT approved and works with factory TPMS sensors. A center cap is included with each wheel.

Confirm your offset and tire clearance before you order. Wheels are not accepted for return once a tire has been mounted.

Installation

A tire shop mounts and balances your tires on the 809 Radar. The wheels then bolt to the Bronco with lug nuts that match the conical seat. Plan on about two hours for a full set, including mounting and balancing.

Bronco Forge lists the offset and backspacing for every size right in the menu. That way you can match the stance you want before the wheels ship. THRET Offroad backs the 809 Radar with a 2-year manufacturer warranty.
