Collection: GMC Canyon Factory Wheels

The GMC Canyon is GMC's midsize pickup, positioned below the full-size Sierra and built for buyers who want truck capability without the size and cost of a half-ton. Factory wheel specifications have shifted more than once across the Canyon's three generations, including a bolt pattern that changed at the 2015 redesign and then changed again at the 2023 redesign. Because the bolt pattern has moved twice, generation matters as much as trim when identifying the correct OEM wheel for a given Canyon. This guide covers the confirmed bolt pattern, center bore, and rim dimensions for each documented Canyon generation, along with how the factory wheel lineup has changed over time.

Quick Specs at a Glance

What Size Wheels Does the GMC Canyon Have?

It depends on generation and trim. The 1st-generation Canyon (2004-2012) used a 15x6.5 wheel on early base trims, moving to a 16x6.5 wheel for 2009 through 2012, with 2WD and 4WD base trims running different offsets on that same 16x6.5 size. The Z71 and ZQ8 Sport packages stepped up to larger wheels during this generation, though the exact width was not consistently verified in the available source.

The 2nd-generation Canyon (2015-2020) used a 16x7 base wheel on SL and SLE trims, a 17x8 wheel on SLE, SLT, and All Terrain trims, and an 18x8.5 wheel on upper trims and appearance packages such as the Nightfall Edition. A 20x8.5 wheel was also offered as a factory option. The 2021 to 2022 facelift years continued with a 17x8 base wheel on Elevation and AT4 trims and an 18x8.5 wheel on Denali and other upper configurations.

The redesigned 3rd-generation Canyon (2023-present) uses a 17x8 wheel as standard on the AT4X trim, paired with LT285/70R17 tires. The Elevation and AT4 trims use an 18x8.5 wheel, and the Denali trim steps up to a 20-inch wheel. Additional wheel choices, including a 17-inch beadlock-capable wheel on the AT4X Edition 1 and AEV packages and larger optional wheels on AT4 and Denali, have been added across the 3rd generation's model years, though width and offset were not verified for every one of those additional options.

What Is the Bolt Pattern on the GMC Canyon?

The 1st-generation Canyon (2004-2012) uses a 6x139.7 bolt pattern with a 100.3mm center bore. The redesigned 2nd-generation Canyon switched to a 6x120 bolt pattern for 2015, with a 66.9mm center bore, and that pattern carried through the 2021 to 2022 facelift years. The redesigned 3rd-generation Canyon, introduced for 2023, moved back to a 6x139.7 bolt pattern, this time with a 78.1mm center bore. A shared bolt pattern between the 1st and 3rd generations does not mean those wheels interchange, since the center bore and confirmed offsets differ between them.

GMC Canyon Center Bore and Offset

Center bore is documented at 100.3mm for the 1st-generation Canyon, 66.9mm for the 2nd generation and its facelift, and 78.1mm for the redesigned 3rd generation. Offset for the 1st generation is confirmed at ET23 on the 2WD base 16x6.5 wheel and ET41 on the 4WD base 16x6.5 wheel, both tied to 2009 through 2012 production. Offset for the 2nd generation is confirmed at ET33 across the 16x7, 17x8, 18x8.5, and 20x8.5 factory wheels documented for 2015 through 2022, based on original GM part numbers. Offset for the 3rd generation is confirmed at ET24 on the 17x8 AT4X wheel and ET26 on the 18x8.5 wheel used on Elevation and AT4, with a further ET28 figure confirmed on a 20x9.0 configuration built on the same 3rd-generation hub specifications. Offset was not verified for every individual wheel option across all three generations, so those figures are left out here rather than estimated.

Do GMC Canyon Wheels Interchange Between Generations?

Even where Canyon generations share basic hub specifications, their factory wheel dimensions can vary by generation, trim, and configuration. Shared bolt pattern and center bore alone do not establish direct-fit interchangeability. The 2nd-generation Canyon uses a completely different bolt pattern, center bore, and lug thread than the 1st and 3rd generations, so 2nd-generation wheels are not compatible with either of the others. The 1st and 3rd generations do share the same 6x139.7 bolt pattern, but their center bores are different, 100.3mm versus 78.1mm, and their confirmed offsets do not match either. A wheel from the 1st-generation Canyon should not be assumed to fit a 3rd-generation truck simply because the bolt pattern lines up.

About the GMC Canyon

The GMC Canyon is a midsize pickup positioned below the full-size Sierra in GMC's truck lineup. It's aimed at buyers who want genuine towing and payload capability along with available off-road hardware, in a footprint that's easier to park and maneuver than a half-ton truck, and it typically competes for attention with the Toyota Tacoma and Ford Ranger in the midsize pickup segment.

The Canyon launched for 2004 as GMC's version of the GMT355 platform, sharing its architecture with the Chevrolet Colorado and offered with 2WD and 4WD configurations along with the off-road-oriented Z71 and sport-styled ZQ8 packages. General Motors redesigned the Canyon for 2015 onto the GMT 31XX platform, adding available diesel power and a broader trim spread that grew to include SLE, SLT, Denali, and All Terrain. A facelift for 2021 updated styling and shifted trim names toward Elevation and AT4. GMC introduced a completely redesigned 3rd-generation Canyon for 2023, offered exclusively with a turbocharged 2.7-liter four-cylinder engine and a trim lineup that expanded to include the off-road-focused AT4X alongside Elevation, AT4, and Denali.

The factory wheel lineup changed alongside these redesigns. The 1st generation used 15x6.5 and 16x6.5 base wheels, with larger wheels offered on off-road and sport packages where the complete dimensions were not consistently verified. The 2nd generation used factory wheels ranging from 16x7 through 20x8.5, including 16x7, 17x8, 18x8.5, and 20x8.5 configurations, with ET33 confirmed across the documented factory sizes. The 3rd generation uses a 17x8 wheel on AT4X, an 18x8.5 wheel on Elevation and AT4, and a 20-inch wheel on Denali, with the width of the Denali wheel not verified. Additional beadlock-capable and larger factory options were introduced in later model years, but their complete dimensions were not consistently verified.

Vehicle Generations & Wheel Changes

The Canyon has been through three generations since its 2004 launch, and the bolt pattern has changed twice, first at the 2015 redesign and again at the 2023 redesign.

The single biggest thing to know: the 1st-generation Canyon uses a 6x139.7 bolt pattern with a 100.3mm center bore and M12 x 1.5 lug thread, the 2nd generation and its facelift use a 6x120 bolt pattern with a 66.9mm center bore and M14 x 1.5 lug thread, and the redesigned 3rd generation returns to a 6x139.7 bolt pattern but with a 78.1mm center bore and M14 x 1.5 lug thread. A shared bolt pattern between the 1st and 3rd generations does not establish direct-fit interchangeability, since the center bore and confirmed offsets differ between them.

OEM Wheel Sizes & Fitment by Year

Exact wheel sizes and offsets varied by trim and model year, so treat these as the confirmed factory setups for each generation.

GMC Canyon I, GMT355 (2004 to 2012)

Offset was not consistently verified across every 1st-generation trim and model year, so ET is included only where confirmed rather than estimated.

GMC Canyon II, GMT 31XX (2015 to 2020)

GMC Canyon II, GMT 31XX Facelift (2021 to 2022)

GMC Canyon III, GMT 31XX-2 (2023 to present)

Additional 20 and 22-inch factory wheel options have also been offered on AT4 and Denali across the 3rd generation's model years. Width and offset were not consistently verified for those additional options, so they are described here by diameter only rather than estimated.

Why Choose Genuine OEM Wheels?

Genuine OEM wheels are designed around the Canyon's factory specifications, including fitment, load rating, brake clearance, and original styling. For most owners, the case for OEM comes up after a curbed rim or a pothole, when the goal is simply getting back to the exact fitment the Canyon already had.

• Factory fit and specifications. Genuine OEM wheels are designed around the Canyon's factory bolt pattern, offset, and hub bore.
• Correct load rating and TPMS compatibility. OEM wheels are designed to meet the Canyon's factory load rating and to accommodate its original tire pressure monitoring system.
• Original styling and factory appearance. A stock-style wheel keeps the Canyon looking factory-correct, which matters if you plan to sell later.

OEM vs. Replica & Aftermarket Wheels

Some drivers choose replica wheels for their similar appearance or price. If your goal is to replace a damaged factory wheel, a genuine OEM wheel offers the best path to the correct fit, finish, and overall appearance, without the extra research replica shopping usually requires. We offer genuine OEM at replica price levels, often less. Here's how the two options typically compare:

How the Canyon Compares

Shoppers cross-shopping the Canyon typically also look at the Toyota Tacoma and Ford Ranger, both established competitors in the midsize pickup segment. The Canyon has its own generation-specific bolt pattern, center bore, and offset specifications, so competitor wheels should not be assumed to be direct-fit replacements.

Frequently Asked Questions

What size wheels does the GMC Canyon have?
It depends on generation and trim. The 1st generation ran 15x6.5 and 16x6.5 wheels on base trims, with larger wheels offered on Z71 and ZQ8 Sport packages. The 2nd generation used 16x7, 17x8, 18x8.5, and 20x8.5 wheels, with ET33 confirmed across those sizes for 2015 to 2022 production. The 3rd generation uses a 17x8 wheel on AT4X, an 18x8.5 wheel on Elevation and AT4, and a 20-inch wheel on Denali.

What is the bolt pattern on the GMC Canyon?
The 1st-generation Canyon (2004-2012) uses a 6x139.7 bolt pattern. The 2nd-generation Canyon (2015-2022, including the facelift) uses a 6x120 bolt pattern. The redesigned 3rd generation, introduced for 2023, returns to a 6x139.7 bolt pattern.

What is the center bore of the GMC Canyon?
The 1st-generation Canyon uses a 100.3mm center bore. The 2nd generation uses a 66.9mm center bore. The redesigned 3rd generation uses a 78.1mm center bore, different from both earlier generations even though it shares the 1st generation's bolt pattern.

What offset do GMC Canyon wheels use?
Offset is confirmed at ET23 and ET41 on the 1st-generation 16x6.5 base wheels, ET33 across the documented 2nd-generation factory wheels, and ET24, ET26, and ET28 on specific 3rd-generation configurations. Offset was not verified for every individual wheel option, so unsupported values are not included.

Do GMC Canyon wheels interchange between generations?
The 2nd-generation Canyon uses a different bolt pattern, center bore, and lug thread than the 1st and 3rd generations, so those wheels are not compatible with each other. The 1st and 3rd generations share a 6x139.7 bolt pattern, but their center bores and confirmed offsets differ, so a wheel from one should not be assumed to be a direct match for the other.

What is the largest factory wheel size on the GMC Canyon?
The largest documented factory wheel option is 22 inches, although exact width and offset were not consistently verified for those later options. The 3rd-generation Denali also uses a 20-inch factory wheel.

Are OEM GMC Canyon wheels better than replicas?
A genuine OEM wheel is designed around the factory fitment, TPMS requirements, and load rating, while keeping the Canyon's original appearance.

Final Thoughts

The GMC Canyon's wheel fitment has moved twice: the 1st generation uses a 6x139.7 bolt pattern with a 100.3mm center bore, the 2nd generation switched to 6x120 with a 66.9mm center bore, and the redesigned 3rd generation returned to 6x139.7, this time with a 78.1mm center bore. That last shift is worth remembering, since a shared bolt pattern between the 1st and 3rd generations does not mean those wheels are interchangeable. Within each generation, confirmed offsets, including ET33 across the documented 2nd-generation wheels and ET24, ET26, and ET28 on specific 3rd-generation configurations, provide useful reference points, though not every trim and wheel option has a confirmed offset. Genuine OEM wheels remain the simplest way to get factory-correct fit and styling, whether replacing a curbed rim or shopping for a full set.
