How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
SUVs carry more curb weight higher off the ground, so wheel strength and rotational mass both matter more than on a comparable sedan — a heavier wheel amplifies body roll and slows steering response exactly where the platform is already working hardest. Forging keeps the wheel light without giving up the load rating the factory suspension geometry was tuned around.
The Ford Bronco Raptor Black Appearance runs a 6x139.7 bolt pattern, 93.1mm center bore, and a 17x8.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 17x9.0J ET10, which tucks the tire under the fender lip on a stock-height Ford Bronco Raptor Black Appearance. Our Maximum Aggressive reference is 18x9.5J ET0 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Ford Bronco Raptor Black Appearance OE Wheel Specs
The 2025 Ford Bronco Raptor Black Appearance (Off-Road SUV) uses a 6x139.7 bolt pattern with a 93.1mm center bore. Factory wheels are 17x8.5J F/R.
Why the factory spec works for most owners:
- Balances ride comfort with everyday fuel efficiency
- A widely used size in this segment, so tire and wheel availability stays strong
- Keeps unsprung weight low for stable, predictable handling
- Maintains clearance for the factory brake calipers and suspension components
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Ford Bronco Raptor Black Appearance (2025) we drill the 6x139.7 pattern and cut the centre bore to 93.1mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 17x8.5J ET34 → ~6.09″ backspacing
- Flush: 17x9.0J ET10 → ~5.39″ backspacing
- Max: 18x9.5J ET0 → ~5.25″ backspacing
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Ford spec, or want a wheel built to a custom offset for your Ford Bronco Raptor Black Appearance? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Frequently Asked Questions
What bolt pattern (PCD) does the Ford Bronco Raptor Black Appearance use?
The 2025 Ford Bronco Raptor Black Appearance uses a 6x139.7 bolt pattern.
How many lug bolts does the Ford Bronco Raptor Black Appearance use?
The Ford Bronco Raptor Black Appearance uses a 6-lug bolt pattern (6x139.7), so you need a 6-lug forged wheel to bolt straight on.
What is the center bore size on the Ford Bronco Raptor Black Appearance?
The Ford Bronco Raptor Black Appearance's center bore is 93.1mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
What size are the factory (stock) wheels on the Ford Bronco Raptor Black Appearance?
Factory wheels on the Ford Bronco Raptor Black Appearance are 17x8.5J F/R.
What is the biggest wheel size I can fit on my Ford Bronco Raptor Black Appearance without rubbing?
The most aggressive fitment we recommend without fender work is 18x9.5J at ET0 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the Ford Bronco Raptor Black Appearance?
For a flush look with minimal to no rubbing, we recommend 17x9.0J at ET10 offset as a starting point on a stock or mildly lowered Ford Bronco Raptor Black Appearance.
Do I need wheel spacers for my Ford Bronco Raptor Black Appearance?
No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.
How do I calculate wheel backspacing for my Ford Bronco Raptor Black Appearance?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 5.39" of backspacing.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.
Can I run staggered wheels (different sizes front and rear) on my Ford Bronco Raptor Black Appearance?
The Ford Bronco Raptor Black Appearance runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M14x1.5, conical-seat lug nut.
Factory Torque Spec: 135 Nm (100 ft-lb). Ford Ranger (current generation) spec on M14x1.5 studs; earlier Ranger generations used M12x1.5 or M14x2.0 threads, confirm for your exact model year.
TPMS: TPMS (Tire Pressure Monitoring System) has been federally mandated on all new light vehicles sold in the US since the 2008 model year. If your wheels use OE-style sensors, have them transferred or cloned to the new wheels at installation.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
