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
Off-road platforms put real, repeated impact loads through the wheel that street-only vehicles never see, so the factory strength margin on the GMC Sierra Denali Ultimate isn't a formality — it's load-bearing in a literal sense. Forging matches that margin at a lower rotational weight than an equivalent cast wheel, which matters both on the trail and on the highway miles between trailheads.
The GMC Sierra Denali Ultimate ships from the factory on a 6x139.7 bolt pattern with a 78.1mm center bore and a 22x9J ET31 wheel. Our flush reference for the GMC Sierra Denali Ultimate is 22x9.5J ET18.; our maximum aggressive reference is 24x10J ET12. — beyond that, expect clearance issues against the fender liner without further modification.
GMC Sierra Denali Ultimate OE Wheel Specs
The GMC Sierra Denali Ultimate ships from the factory on 6x139.7 bolt pattern wheels with a 78.1mm center bore. The stock wheel size is 22x9J ET31, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the GMC Sierra Denali Ultimate (2016) we drill the 6x139.7 pattern and cut the centre bore to 78.1mm 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.

Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 22x9J | ET31 | 6.22 in (158 mm) | — | — |
| Flush | 22x9.5J | ET18 | 5.96 in (151 mm) | −7 mm | +19 mm |
| Maximum | 24x10J | ET12 | 5.97 in (152 mm) | −6 mm | +32 mm |
Vehicles With the Same Hub as the GMC Sierra Denali Ultimate (6x139.7, 78.1 mm Bore)
In our database, 79 other vehicle entries from 6 makes use exactly the same 6x139.7 bolt pattern and 78.1 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.
6x139.7 is used by 4.0% of the vehicle pages in our English fitment guide (258 of 6,503); 31.0% of those also use a 78.1 mm center bore.
Hub-Centric Rings for a 78.1 mm Center Bore
A wheel with a center bore larger than 78.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 84.1 mm | 84.1 → 78.1 mm |
| 93.1 mm | 93.1 → 78.1 mm |
| 100.1 mm | 100.1 → 78.1 mm |
| 106.1 mm | 106.1 → 78.1 mm |
ANKUSI forged wheels are bored to exactly 78.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the GMC Sierra Denali Ultimate use?
The 2016 GMC Sierra Denali Ultimate uses a 6x139.7 bolt pattern.
How many lug bolts does the GMC Sierra Denali Ultimate use?
The GMC Sierra Denali Ultimate uses a 6-lug bolt pattern (6x139.7), so you need a 6-lug forged wheel to bolt straight on.
What is the center bore size on the GMC Sierra Denali Ultimate?
The GMC Sierra Denali Ultimate's center bore is 78.1mm. 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 Sierra Denali Ultimate?
Factory wheels on the GMC Sierra Denali Ultimate are 22x9J ET31.
What does a flush wheel fitment look like on the GMC Sierra Denali Ultimate?
For a flush look with minimal to no rubbing, we recommend 22x9.5J at ET18 offset as a starting point on a stock or mildly lowered GMC Sierra Denali Ultimate.
Do I need wheel spacers for my GMC Sierra Denali Ultimate?
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 Sierra Denali Ultimate?
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 5.96" 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 Sierra Denali Ultimate?
The GMC Sierra Denali Ultimate 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.
