Factory wheel sizes on the GMC Sierra HD
Across the 3 GMC Sierra HD trims with a documented factory wheel, the OE diameter is 18-20 inch, width 8-8.5J and offset ET44. A forged wheel that keeps the 8x180 bolt pattern and the 124.1 mm hub bore and stays inside that offset range bolts on without spacers or hub rings. Going one inch up in diameter with a lower-profile tyre keeps the rolling circumference inside the usual 1.5% tolerance; every extra 0.5J of width moves the outer lip about 6 mm outward at the same offset, and each 5 mm less offset moves the whole wheel 5 mm outward.

Vehicles With the Same Hub as the GMC Sierra HD (8x180, 124.1 mm Bore)
In our database, 5 other Chevrolet entries use exactly the same 8x180 bolt pattern and 124.1 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.
8x180 is used by 0.2% of the vehicle pages in our English fitment guide (11 of 6,503); 100.0% of those also use a 124.1 mm center bore.
Hub-Centric Rings for a 124.1 mm Center Bore
A wheel with a center bore larger than 124.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 130.1 mm | 130.1 → 124.1 mm |
ANKUSI forged wheels are bored to exactly 124.1 mm for this vehicle, so no ring is needed.

Bolt pattern and center bore were checked against at least two independent fitment references before publication.

FAQ
What is the bolt pattern on a GMC Sierra HD?
The GMC Sierra HD uses a 8x180 bolt pattern with a 124.1mm center bore across every Sierra HD variant in our database (3 guides, 2015–2024).
What is the GMC Sierra HD center bore?
The hub-centric center bore is 124.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all GMC Sierra HD years share the same wheel fitment?
The bolt pattern and center bore are the same across the years we cover, but OE wheel width and offset differ by trim, so check the exact model line before choosing an aftermarket size.
Which forged wheels fit the GMC Sierra HD?
Any wheel drilled 8x180 with a 124.1mm hub bore in the offset range shown on the model guide. ANKUSI forges wheels to order for this exact specification, in 14–24 inch diameters, so no adapters or hub rings are needed.
