Factory wheel sizes on the GMC Canyon
Across the 5 GMC Canyon trims with a documented factory wheel, the OE diameter is 17-20 inch, width 8-8.5J and offset ET33. A forged wheel that keeps the bolt pattern and hub bore of your generation (see the table above) 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 Canyon (6x120, 66.9 mm Bore)
In our database, 26 other vehicle entries from 4 makes use exactly the same 6x120 bolt pattern and 66.9 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.
6x120 is used by 0.5% of the vehicle entries in our database (34 of 6,503); 97.1% of those also use a 66.9 mm center bore.
Hub-Centric Rings for a 66.9 mm Center Bore
A wheel with a center bore larger than 66.9 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 67.1 mm | 67.1 → 66.9 mm |
| 70.1 mm | 70.1 → 66.9 mm |
| 70.5 mm | 70.5 → 66.9 mm |
| 71.6 mm | 71.6 → 66.9 mm |
| 73.1 mm | 73.1 → 66.9 mm |
ANKUSI forged wheels are bored to exactly 66.9 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a GMC Canyon?
The GMC Canyon uses a 6x120 bolt pattern on most variants we cover with a 66.9mm center bore. Other generations use 6x139.7 / 78.1mm (2023–2023). Always check the exact year and trim before ordering.
What is the GMC Canyon center bore?
The hub-centric center bore is 66.9 mm on the most common generation; see the table for variants. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all GMC Canyon years share the same wheel fitment?
No. The bolt pattern or center bore changed between generations, so wheels are not interchangeable across all years. Use the year-by-year table on this page to pick the right specification.
Which forged wheels fit the GMC Canyon?
Any wheel drilled 6x120 with a 66.9mm 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.
