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.
Ram 2500 Heavy Duty Rebel OE Wheel Specs
The 2023 Ram 2500 Heavy Duty Rebel (HD Off-Road) uses a 8*165.1 bolt pattern with a 121.3mm center bore. Factory wheels are 20x8.0J 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
Flush Fitment
For a flush look with minimal rubbing, F/R 20x9.0J ET18 is the recommended starting point on a stock or mildly lowered Ram 2500 Heavy Duty Rebel.
Maximum Aggressive Fitment
F/R 20x10.0J ET0 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference

- OE: 20x8.0J ET42 → ~6.15″ backspacing
- Flush: 20x9J ET18 → ~5.71″ backspacing
- Max: 20x10J ET0 → ~5.5″ backspacing
