The 2020 GMC Acadia dropped in with a mid-cycle refresh that included a new exterior design, new exterior paint options, a redesigned cabin, the latest tech offerings, and an updated engine line. Critically, the 2020 Acadia also arrived with a freshened trim level lineup highlighted by the addition of the all-new off-road-oriented AT4, which upgrades the crossover with a rugged new look and several dirt-duty features. While equipped as standard with 17-inch wheels, it’s not well-known that 20-inchers are also offered. As such, we’re shedding some light on the GMC Acadia AT4’s available wheel-and-tire option.

As a reminder, the 2020 GMC Acadia AT4 is equipped as standard with 17-inch Gloss Black aluminum wheels wrapped in all-terrain rubber.
However, if customers prefer extra diameter in the corners, there’s also a set of 20-inch machined aluminum wheels with dark accents (RPO code SSZ) on offer. These upsized rollers ditch the standard all-terrain tires in favor of an all-season compound (RPO code QNU).
The 2020 GMC Acadia AT4’s optional 20-inch wheel-and-tire packages are priced at $900.
| Vehicle | Wheels | Tires |
|---|---|---|
| 2020 Acadia AT4 – Standard | 17-inch Gloss Black aluminum (Q7D) | All-Terrain (5GV) |
| 2020 Acadia AT4 – Optional | 20-inch Machined Aluminum with Dark Accents (SSZ) | All-Season (QNU) |
Clearly, for those buyers who want to optimize the off-road performance of their 2020 GMC Acadia AT4, the standard 17-inch wheels and all-terrain tires are the way to go. However, the optional 20-inch wheels and all-season tires are a nice alternative for folks who want some extra flash, rather than chunky rubber.

I got the AT4 spec’d tires for our Acadia, huge improvement, 17 of course.
Like the way these things look with the AT/4 package.
The 20 ×8 inch 6 spoke wheel package machine face and high gloss black painted pockets that was use for the Acadiia black edition, which is now called the Elevation edition for the Acadia will look better on the Acadia AT4. Hands down this vehicle needs more off road package options, like a lift kit to compete with other vehicles in this market size.
