  • Most other 2026 wheel choices carry over unchanged into 2027.

2027 GMC Canyon Wheels: What Changed

GMC is reshuffling the wheel lineup for the 2027 Canyon, introducing four new designs while discontinuing three choices from the 2026 model year. This is not a full overhaul — it is a trim-specific update focused on the AT4X, Denali, AT4, and Elevation. According to GM Authority's August 2026 report, GMC had not yet released images of the new designs at publication time, so descriptions come straight from ordering information.

Video Highlights:

  • 2027 Canyon AT4X rides on 33-inch tires with 17-inch wheels
  • New for 2027: straight black wheel finish replacing the two-tone machined black
  • Rock rails remain standard on AT4X
  • Engine upgraded to 350 hp / 455 lb-ft of torque

The first-drive review above confirms the most visible change on the ground: the AT4X's wheels switch from a two-tone machined black finish to straight black for 2027, a look that pairs especially well with lighter paint colors like White Sand.

Why It Matters

Wheel changes affect more than appearance. Smaller diameter wheels (like the AT4X's 17-inch rims) leave more sidewall for off-road traction, while larger 20-inch designs on the Denali prioritize on-road style and ride refinement.

New Wheels vs. Discontinued Wheels

Here is the complete trim-by-trim breakdown of what is arriving and what is leaving for 2027.

Carryover Designs

The remaining Canyon wheel choices carry over unchanged from 2026. The four new designs are a targeted update, not a complete lineup replacement.

How to Order the Right Wheels: Step-by-Step

Choosing the correct wheel configuration for your 2027 Canyon comes down to trim selection, package awareness, and understanding RPO codes on your build sheet.

1

Pick Your Trim First

Wheel availability is trim-locked. The RID wheel only comes on the AT4X, and the NZH only on the Denali. Decide between off-road capability (AT4X/ZR2) and luxury (Denali) before comparing rims.

2

Check Package Requirements

The 20-inch NZS Gloss Black wheel on the AT4 requires the Nightfall Edition (PDI) or Nightfall Essentials Package (PDJ). Confirm the package cost fits your budget before committing.

3

Verify RPO Codes on the Build Sheet

When your order is placed, confirm codes RID, NZH, NZS, or SKZ appear correctly. Dealers can verify these against GMC's ordering information.

4

Plan Your Tire Sizing

Match wheel diameter to your use case: 17-inch for maximum sidewall off-road, 18-inch as a compromise, 20-inch for street-oriented styling.

Dealer-Installed Options

LPO-coded wheels and accessories (like the SKZ) are typically dealer-installed rather than factory-fitted. Confirm installation timing and any additional labor costs with your dealer at order time.

Off-Road Wheel & Tire Considerations

The AT4X's 17-inch wheel and 33-inch tire combination is a deliberate engineering choice. As the first-drive review notes, the Canyon AT4X is one of only two midsize trucks offering both front and rear locking differentials (the other being the Jeep Gladiator), making wheel and tire selection critical to its capability formula.

SetupWheel SizeBest ForTrade-off
AT4X stock17-inRock crawling, Moab/Rubicon trailsLess street style

AT4 w/ SKZ18-inMixed on/off-road useModerate sidewall
AT4 w/ NZS20-inStreet and light trailMinimal sidewall flex
Accessory Expandability

All ZR2 and AT4X frames come equipped from the factory with brackets that accept dealer-installed down-shocks, and the standard frame-mounted rock rails support bolt-on accessory steps — removable hardware that won't hold you back on the trail.

Buyer's Checklist

Before You Order Your 2027 Canyon:

  • Confirm which of the four new wheel designs (RID, NZH, NZS, SKZ) fits your chosen trim
  • Verify Nightfall package requirements if you want the NZS 20-inch wheel
  • Check the build sheet RPO codes before finalizing the order
  • Decide on tire diameter based on your off-road vs. street priorities
  • Ask your dealer about LPO accessory wheels and installation timing

FAQ

Q: How many new wheels does the 2027 GMC Canyon offer?

Four new designs: the 17-inch Deep Void painted aluminum AT4X wheel (RID), the 20-inch Carbon Gray-accented Denali wheel (NZH), the 20-inch Gloss Black AT4 wheel (NZS), and the 18-inch Gloss Black machine-faced option for AT4 and Elevation (SKZ). Three 2026 designs — R34, RHO, and RD4 — are discontinued.

Q: Did the 2027 Canyon AT4X wheel size change?

No. The AT4X keeps its 17-inch diameter with 33-inch tires. Only the finish changed, moving from a two-tone machined black to a straight black Deep Void painted design for 2027.

Q: Are the new 2027 Canyon wheels available across all trims?

No. The RID is standard on AT4X only, the NZH is standard on Denali only, and the NZS is tied to AT4 Nightfall packages. The SKZ is an option on both AT4 and Elevation trims.

Q: Do wheel changes affect towing or capability on the 2027 Canyon?

GMC rates the base truck at 7,700 lbs of towing and the ZR2 at 6,000 lbs, and the company notes towing is not horsepower-limited. Wheel selection is primarily about appearance and tire sizing rather than towing capacity.
