The THRET Offroad 701 Storm is a cast aluminum wheel for the 2021, 2022, 2023, 2024, 2025, and 2026 Ford Bronco. THRET Offroad gives it a 10-spoke concave face. Stainless steel rivets ring the outer lip to help it resist rust. The wheel is drilled for the Bronco's factory 6x139.7 bolt pattern, so it bolts straight on with no adapters.

Two Finishes

THRET Offroad builds the 701 Storm in two finishes. Gloss Black/Milled has a shiny black face with cut metal accents on the spokes. Satin Black is a flat, low-shine black across the whole wheel. Both finishes come in all four sizes.

Sizes and Offsets

The 701 Storm comes in four size and offset combinations for the Bronco. The 17x9, 18x9, and 20x9 each come with a -12mm offset. The 20x9 also comes with a 0mm offset.

Every size in the menu lists three numbers. The first is the wheel size, such as 17x9. That means a 17-inch diameter and a 9-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 0mm offset puts the mounting face right at the center of the wheel, so the wheel sits a little farther in than the -12mm version.

Backspacing is the distance from the mounting face to the inner edge of the wheel. It is measured in inches. The -12mm sizes have 4.5 inches of backspacing. The 0mm size has 5.0 inches. A lower backspacing number puts more of the wheel outside the hub and gives a wider stance.

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 701 Storm 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 701 Storm. 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 701 Storm with a 2-year manufacturer warranty.
