Wheel Size & Offset at a Glance
| Configuration | Wheel Size & Offset |
|---|---|

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 Ram 1500 Rebel Havoc Edition runs a 6x139.7 bolt pattern, 77.8mm center bore, and a 18x8.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x9.0J ET0, which tucks the tire under the fender lip on a stock-height Ram 1500 Rebel Havoc Edition. Our Maximum Aggressive reference is 20x10.0J ET-12 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Ram 1500 Rebel Havoc Edition OE Wheel Specs
The 2023 Ram 1500 Rebel Havoc Edition (Off-Road Truck) uses a 6x139.7 bolt pattern with a 77.8mm center bore. Factory wheels are 18x8.0J F/R.
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, F/R 18x9.0J ET0 is a commonly used starting point — clearance must be verified on a stock or mildly lowered Ram 1500 Rebel Havoc Edition.
Maximum Aggressive Fitment
F/R 20x10.0J ET-12 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: 18x8.0J ET19 → ~5.25″ backspacing
- Flush: 18x9.0J ET0 → ~5″ backspacing
- Max: 20x10.0J ET-12 → ~5.03″ backspacing
A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
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 Ram spec, or want a wheel built to a custom offset for your Ram 1500 Rebel Havoc Edition? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
