Details
Fitment
The THRET Offroad 801 Vulcan 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: 17x9, 20x9. Offset options: +18mm, -12mm, 0mm. Backspacing ranges from 5.7" to 5.0". Confirm tire clearance for your tire size, suspension, and fender setup before mounting.
Best For
Bronco owners who want a bold Y-spoke wheel with several 20-inch stance options but a simpler two-finish lineup.
Design
The 801 Vulcan uses an 8-spoke Y pattern with a lip around the outer edge. It comes in Gloss Black or Satin Black/Dark Tint. The 20x9 size offers -12mm, 0mm, and +18mm offsets depending on finish.
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, Satin Black/Dark Tint. 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
Which offset should I pick on the 20x9?
The -12mm offset pushes the wheel out for the widest stance. The 0mm offset sits a little farther in. The +18mm offset keeps the wheel tucked closer to the frame. Your tire size, lift height, and fender flares decide how far out the wheel can sit without rubbing.
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 801 Vulcan ranges from 4.5 to 5.7 inches on the Bronco sizes. A lower number sets more of the wheel outside the hub.
Why is it drilled for two bolt patterns?
THRET Offroad drills the 801 Vulcan for both 6x135 and 6x139.7 so one wheel fits more trucks. The Bronco uses the 6x139.7 holes.
Do I need new lug nuts?
The 801 Vulcan 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 801 Vulcan 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.
