Details
Fitment
The THRET Offroad 901 Monarch uses the Ford Bronco's 6x139.7 bolt pattern and is listed here for the 2021-2027 Ford Bronco. Hub bore: 106. Load rating: 2,500 lbs per wheel.
Available sizes: 20x10, 20x12, 22x10, 22x12. Offset options: -21mm, -44mm, -51mm. Backspacing ranges from 4.6" to 4.5". Confirm tire clearance for your tire size, suspension, and fender setup before mounting.
Best For
Bronco owners building for a very wide street-truck stance with 20- or 22-inch wheels and up to a 12-inch width.
Design
The 901 Monarch uses an 8 split-spoke face, exposed lugs, and a deep outer lip. It is offered in 20- and 22-inch diameters with 10- and 12-inch widths. The 12-inch versions use very aggressive negative offsets and will extend past factory fenders.
Size, Offset & Stance
Offset changes how far the wheel sits in or out. A more negative offset pushes the wheel farther toward the fender; a more positive offset keeps it farther in. Use the size menu to compare the exact offset and backspacing before you order.
Finish options: Gloss Black/Milled, Gloss Black. Not every finish is offered in every size.
Installation
Have the tires mounted and balanced by a tire shop. These THRET wheel applications work with factory TPMS sensors and use a conical lug seat. Confirm your lug nuts match the wheel before installation. Wheels are not accepted for return once a tire has been mounted.

Questions
Will the 12-inch-wide sizes stick out past my fenders?
Yes. The 20x12 at -44mm and the 22x12 at -51mm push the tire well past the factory fender flares. Most builds that run them also run a lift, wider flares, or trimmed or deleted fenders.
Which size sits the farthest in?
The 20x10 and 22x10, both at -21mm, sit the farthest in of the 901 Monarch sizes. They still sit wider than a factory wheel.
What does the backspacing number in the size menu mean?
Backspacing is the distance in inches from the mounting face to the inner edge of the wheel. The 901 Monarch ranges from 4.5 to 4.8 inches on the Bronco sizes. A lower number sets more of the wheel outside the hub.
Do I need new lug nuts?
The 901 Monarch uses a conical acorn and spline lug seat. Check that your lug nuts match that seat style before you mount the wheels, or pick up a set that does.
Will my factory TPMS sensors work?
Yes. THRET Offroad lists the 901 Monarch as TPMS compatible, so your factory sensors move over to the new wheels.
Is a center cap included?
Yes. A center cap comes with each wheel.
