Fitment
The THRET Offroad 702 Firewall 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, 18x9, 20x9. Offset options: -12mm, +18mm. Backspacing ranges from 4.5" to 5.7". Confirm tire clearance for your tire size, suspension, and fender setup before mounting.
Best For
Bronco owners who want a simple cast wheel in bronze or satin black with both tucked and wider 17-inch stance options.
Design
The 702 Firewall is a cast aluminum wheel offered in Bronze or Satin Black. The 17x9 version is available in both -12mm and +18mm offsets, while the 18x9 and 20x9 use the wider-looking -12mm setup.
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: Bronze, Satin 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
Which offset should I pick on the 17x9?
The -12mm offset pushes the wheel out for a wider stance. 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 -12mm sizes have 4.5 inches and the +18mm size has 5.7 inches. A lower number sets more of the wheel outside the hub.
Is this a beadlock wheel?
No. The 702 Firewall is a standard cast wheel with no beadlock ring. For a true beadlock, see the THRET Offroad 602 Maze.
Do I need new lug nuts?
The 702 Firewall 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 702 Firewall 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.
