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.
GMC Hummer EV OE Wheel Specs
The 2022 GMC Hummer EV (EV Truck) uses a 8x165.1 bolt pattern with a 116.7mm center bore. Factory wheels are 18x9J at ET35.
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 with minimal rubbing, 18x9.5J ET18 is the recommended starting point on a stock or mildly lowered GMC Hummer EV.
Maximum Aggressive Fitment
20x10J ET10 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: 18x9J ET35 → ~6.38″ backspacing
- Flush: 18x9.5J ET18 → ~5.96″ backspacing
- Max: 20x10J ET10 → ~5.89″ 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 GMC spec, or want a wheel built to a custom offset for your GMC Hummer EV? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
