GMC Envoy wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2005 | GMC Envoy Denali | 6x127 | 78.1 mm | 17x7J ET50 |
| 2005 | GMC Envoy XL Denali | 6x127 | 78.1 mm | 17x7J ET50 |
Factory wheel sizes on the GMC Envoy
Across the 2 GMC Envoy trims with a documented factory wheel, the OE diameter is 17 inch, width 7J and offset ET50. A forged wheel that keeps the 6x127 bolt pattern and the 78.1 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 Envoy (6x127, 78.1 mm Bore)
In our database, 9 other vehicle entries from 4 makes use exactly the same 6x127 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.
6x127 is used by 0.2% of the vehicle entries in our database (12 of 6,503); 91.7% 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.
Sources and Last Update
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 Envoy?
The GMC Envoy uses a 6x127 bolt pattern with a 78.1mm center bore across every Envoy variant in our database (2 guides, 2005).
What is the GMC Envoy center bore?
The hub-centric center bore is 78.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all GMC Envoy 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 Envoy?
Any wheel drilled 6x127 with a 78.1mm 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.
