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 GMC Hummer EV Icon 25 runs a 8x165.1 bolt pattern, 116.7mm center bore, and a 22x9.5J at ET35, front and rear, wheel from the factory. Our Flush Fitment reference is 22x10J ET18, which tucks the tire under the fender lip on a stock-height GMC Hummer EV Icon 25. Our Maximum Aggressive reference is 24x10J ET10 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
GMC Hummer EV Icon 25 OE Wheel Specs
The 2027 GMC Hummer EV Icon 25 (EV Truck) uses a 8x165.1 bolt pattern with a 116.7mm center bore. Factory wheels are 22x9.5J 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
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the GMC Hummer EV Icon 25 (2027) we drill the 8x165.1 pattern and cut the centre bore to 116.7mm 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, 22x10J ET18 is the recommended starting point on a stock or mildly lowered GMC Hummer EV Icon 25.
Maximum Aggressive Fitment
24x10J ET10 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.
Real-World Fitment Notes
Chassis: EV heavy-duty air suspension. Wheels: 8x165.1 heavy-load capacity wheels. Brakes: Massive inner barrel clearance required. Tires: 35x12.50 R22.

Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most GMC Hummer EV Icon 25 owners.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 22x9.5J ET35 → ~6.63″ backspacing
- Flush: 22x10J ET18 → ~6.21″ backspacing
- Max: 24x10J 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 Icon 25? 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 GMC Hummer EV Icon 25 (2027)
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 8x165.1 pattern and the 116.7mm 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 GMC orders on this platform land somewhere between the 22x10J ET18 flush setup and the 24x10J ET10 aggressive setup referenced above.
We do not hold 8x165.1 wheels on a shelf — they are forged to order, which is why any offset, width and bore combination on this page is buildable rather than limited to a stock list.
Frequently Asked Questions
What bolt pattern (PCD) does the GMC Hummer EV Icon 25 use?
The 2027 GMC Hummer EV Icon 25 uses a 8x165.1 bolt pattern.
How many lug bolts does the GMC Hummer EV Icon 25 use?
The GMC Hummer EV Icon 25 uses a 8-lug bolt pattern (8x165.1), so you need a 8-lug forged wheel to bolt straight on.
What is the center bore size on the GMC Hummer EV Icon 25?
The GMC Hummer EV Icon 25's center bore is 116.7mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
What size are the factory (stock) wheels on the GMC Hummer EV Icon 25?
Factory wheels on the GMC Hummer EV Icon 25 are 22x9.5J at ET35.
What is the biggest wheel size I can fit on my GMC Hummer EV Icon 25 without rubbing?
The most aggressive fitment we recommend without fender work is 24x10J at ET10 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the GMC Hummer EV Icon 25?
For a flush look with minimal to no rubbing, we recommend 22x10J at ET18 offset as a starting point on a stock or mildly lowered GMC Hummer EV Icon 25.
Do I need wheel spacers for my GMC Hummer EV Icon 25?
No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.
How do I calculate wheel backspacing for my GMC Hummer EV Icon 25?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 6.21" of backspacing.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.
Can I run staggered wheels (different sizes front and rear) on my GMC Hummer EV Icon 25?
The GMC Hummer EV Icon 25 runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
Vehicles With the Same Hub as the GMC Hummer EV Icon 25 (8x165.1, 116.7 mm Bore)
In our database, 18 other vehicle entries from 4 makes use exactly the same 8x165.1 bolt pattern and 116.7 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
8x165.1 is used by 0.4% of the vehicle pages in our English fitment guide (29 of 6,503); 65.5% of those also use a 116.7 mm center bore.
Hub-Centric Rings for a 116.7 mm Center Bore
A wheel with a center bore larger than 116.7 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 130.1 mm | 130.1 → 116.7 mm |
ANKUSI forged wheels are bored to exactly 116.7 mm for this vehicle, so no ring is needed.
