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.


Ford Bronco Filson OE Wheel Specs
The 2027 Ford Bronco Filson (Off-Road SUV) uses a 6x139.7 bolt pattern with a 93.1mm center bore. Factory wheels are 17x8.5J at ET55 offset, front and rear.
Why the factory spec works for most owners:
- Supports higher payload and towing capacity
- Preserves ground clearance for towing, hauling and light off-road use
- Matches tire sizing commonly available for this class of vehicle
- Maintains clearance for the factory suspension and brake package
Flush Fitment
For a flush look, a 17x9.0J wheel at ET20 offset (front and rear) is a commonly used starting point — clearance must be verified on a stock or mildly lowered Ford Bronco Filson.
Maximum Aggressive Fitment
18x9.5J at ET12 offset is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

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 ET20 → ~5.79" backspacing
- Max: 18x9.5J ET12 → ~5.72" backspacing
