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
Trucks live and die on unsprung weight and load capacity — every pound added at the wheel is a pound the suspension has to control over every bump, fully loaded or not. Forging the wheel instead of casting it lets us hold the factory load rating while cutting rotational mass, which pays off directly in ride quality and steering response on a vehicle that spends real time towing or hauling.
The Ford Ranger Raptor 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 ET18, which tucks the tire under the fender lip on a stock-height Ford Ranger Raptor. Our Maximum Aggressive reference is 18x9.5J ET10 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Ford Ranger Raptor OE Wheel Specs
The 2019 Ford Ranger Raptor (Off-Road Pickup) 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 drivability
- A commonly used size for this vehicle class, supporting parts and tire availability
- Maintains clearance for the factory suspension and brake components
- Provides stable, predictable handling across normal driving conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Ford Ranger Raptor (2019) 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.

Flush Fitment
For a flush look with minimal rubbing, F/R 17x9.0J ET18 is the recommended starting point on a stock or mildly lowered Ford Ranger Raptor.
Maximum Aggressive Fitment
F/R 18x9.5J ET10 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Real-World Reference Cases
The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.
Case 1: Daily Driver (Factory-Style)
Profile: Everyday driving, prioritizes comfort and low running cost.
Setup: 17x8.5J ET55
Cost: ~$620
Outcome: Minimal visual change, ride and fuel economy essentially unaffected.
Case 2: Balanced Enthusiast (Balanced / Flush Fit)
Profile: Wants a sportier stance without sacrificing daily usability.
Setup: 17x9.0J ET18
Cost: ~$3,000
Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.
Case 3: Show Build (Max Aggressive)
Profile: Built primarily for shows or occasional track/show use.
Setup: 18x9.5J ET10
Cost: ~$5,500
Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.
Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 17x8.5J ET55 → ~6.92″ backspacing
- Flush: 17x9.0J ET18 → ~5.71″ backspacing
- Max: 18x9.5J ET10 → ~5.64″ 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 Ranger Raptor? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Custom Forged Wheels for the Ford Ranger Raptor (2019)
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 6x139.7 pattern and the 93.1mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose — most Ford orders on this platform land somewhere between the 17x9.0J ET18 flush setup and the 18x9.5J ET10 aggressive setup referenced above.

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.
