The 2022 GMC Trucks Acadia sits in the modern midsize SUV category, balancing family use, daily driving, and trim-specific styling that ranges from more rugged to more upscale. That matters when it comes to tires, because this Acadia does not use one universal fitment across the lineup. Depending on sub-model, it uses 255/65R17, 235/65R18, or 235/55R20 radial tires, all with different wheel diameters. The main tire decision is less about old-school construction choices and more about matching the correct size to the exact trim, wheel package, and intended look. Before choosing a tire, confirm the sub-model and the wheel diameter currently on the vehicle.
Which Tire Size Is Right for The 2022 GMC Trucks Acadia
Three tire sizes apply to the 2022 GMC Trucks Acadia, and they vary by sub-model and wheel diameter. The first step is identifying the exact trim and confirming whether the vehicle is on 17-inch, 18-inch, or 20-inch wheels, since the correct radial tire depends on that combination. Once that is settled, the decision becomes choosing the right tire type and product characteristics within the proper size.
The size 255/65R17 indicates a metric radial tire with a 255 millimeter section width, a 65-series aspect ratio, and fitment for a 17-inch wheel. On the 2022 GMC Trucks Acadia, this size is tied to a specific trim setup and gives the buyer a larger-section tire on a 17-inch rim. Available product choice in this size includes a BFGoodrich All Terrain T/A KO2 with raised white letter sidewall styling. This is the size to evaluate when the Acadia has the 17-inch wheel package and a more rugged tire presentation is part of the goal.
The size 235/55R20 uses modern metric radial sizing, with a 235 millimeter section width, a 55-series profile, and a 20-inch rim diameter. On the 2022 GMC Trucks Acadia, this fitment belongs to certain trims that use the larger wheel package rather than the 17-inch or 18-inch setup. The lower profile relative to the other Acadia sizes makes wheel confirmation especially important before replacement. This is the size to focus on when the vehicle is equipped with 20-inch wheels and the goal is to stay aligned with that trim-specific fitment.
The size 235/65R18 is a metric radial format that combines a 235 millimeter section width with a 65-series profile for an 18-inch wheel. For the 2022 GMC Trucks Acadia, this size appears on trims that do not share the 17-inch AT4 setup or the 20-inch wheel package used elsewhere in the range. Its overall dimensions are close in theme to the other Acadia fitments, but the wheel diameter still makes it a distinct selection. This is the right size to evaluate when the vehicle currently wears 18-inch wheels and the trim calls for that configuration.
Sub-model fitment matters on the 2022 GMC Trucks Acadia because tire size changes with trim and wheel package. Some sub-models use a single size, while SLE and SLT can use either 18-inch or 20-inch fitments, so confirming the exact setup on the vehicle is essential before replacement.

2022 GMC Trucks Acadia AT4
The 2022 GMC Trucks Acadia AT4 uses the 255/65R17 radial tire size. Tire selection for this trim starts with confirming the 17-inch wheel setup, then comparing available products for the kind of road use, sidewall appearance, and rim-width compatibility that suit the vehicle.
The 2022 GMC Trucks Acadia Denali uses the 235/55R20 radial tire size. That makes 20-inch wheel confirmation the key first step, followed by choosing a tire that matches the vehicle's existing wheel package and the owner's priorities for appearance and driving use.
The 2022 GMC Trucks Acadia SLE can use either 235/55R20 or 235/65R18 radial tires. Tire choice for this trim depends on verifying which wheel diameter is actually on the vehicle, since the 18-inch and 20-inch setups are not interchangeable by size alone.
The 2022 GMC Trucks Acadia SLE Elevation Edition uses the 235/55R20 radial tire size. This trim-specific fitment points the buyer toward 20-inch wheel verification first, then toward selecting a tire that suits the Acadia's existing stance and wheel presentation.
The 2022 GMC Trucks Acadia SLT can use either 235/55R20 or 235/65R18 radial tires. The practical step is confirming whether the vehicle has 18-inch or 20-inch wheels before comparing tire choices, since that determines the correct fitment path.
The 2022 GMC Trucks Acadia SLT Elevation Edition uses the 235/55R20 radial tire size. Buyers should confirm the 20-inch wheel setup and then focus on tire selection within that size rather than comparing it with the Acadia's 17-inch or 18-inch trim fitments.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Owners usually need to sort out trim-specific tire size, wheel diameter, available product choices, and practical fitment checks before replacing tires on a 2022 GMC Trucks Acadia. These FAQs focus on those exact decisions.
Tire Size & Fitment
What tire size fits a 2022 GMC Trucks Acadia?
The 2022 GMC Trucks Acadia uses three possible tire sizes: 255/65R17, 235/65R18, and 235/55R20. The correct one depends on the exact sub-model and wheel package. AT4 uses 255/65R17, Denali uses 235/55R20, and several other trims may use either 18-inch or 20-inch fitments.
The safest way to choose is to confirm the trim level and then verify the wheel diameter actually installed on the vehicle. SLE and SLT can appear with more than one size, so relying on the model name alone is not enough. Checking the sidewall on the current tire and measuring the wheel diameter helps prevent ordering the wrong size.
What size rim does a 2022 GMC Trucks Acadia use?
A 2022 GMC Trucks Acadia can use 17-inch, 18-inch, or 20-inch rims depending on trim. The 255/65R17 size fits a 17-inch wheel, 235/65R18 fits an 18-inch wheel, and 235/55R20 fits a 20-inch wheel. Rim diameter is built into the tire size itself, so the final number is critical.
That wheel diameter should be confirmed before replacing tires, especially if the Acadia has had wheels changed since new. An 18-inch tire cannot be mounted on a 20-inch wheel, and the same is true across the other sizes. Once diameter is confirmed, it becomes much easier to compare tire options that suit the vehicle's current setup.
Why does the 2022 GMC Trucks Acadia have more than one tire size?
The 2022 GMC Trucks Acadia has more than one tire size because different sub-models use different wheel packages. AT4 uses 17-inch fitment, Denali uses 20-inch fitment, and SLE and SLT can appear with either 18-inch or 20-inch sizes. The tire size follows the trim's wheel diameter and overall package.
That means the first question is not simply which tire is popular for an Acadia, but which exact configuration is on the vehicle now. Trim badges help, yet they are not always enough when a model could be equipped multiple ways. Looking at the sidewall size and confirming the wheel diameter avoids confusion between otherwise similar Acadia trims.
Choosing the Right Tire
What should I consider when choosing a 255/65R17 tire for a 2022 GMC Trucks Acadia?
For a 2022 GMC Trucks Acadia using 255/65R17, start with the correct size, radial construction, and the wheel specifications already on the vehicle. Available choice in this size includes a BFGoodrich All Terrain T/A KO2 with raised white letter sidewalls, so the tire's visual style and intended use become part of the decision.
Rim-width compatibility also matters in this size, especially if the Acadia has aftermarket wheels. The available 255/65R17 product is built for a 7.0 to 9.0 inch rim-width range, which should be checked against the actual wheel before installation. From there, compare the tire's appearance and use case with how the vehicle is driven.
What sidewall styles are available for 2022 GMC Trucks Acadia tires?
Current product choice for the 2022 GMC Trucks Acadia includes an RWL sidewall in 255/65R17. RWL stands for raised white letter, which gives the tire a more pronounced and utility-oriented appearance than a plain black sidewall. That visual difference can matter as much as the tread type on some trim packages.
Sidewall style should still come after confirming the correct tire size for the sub-model and wheel diameter. A sidewall treatment may suit the look of one Acadia setup but not another, especially when comparing a more rugged trim with a larger-wheel street-oriented package. Appearance choice works best once the fitment is already correct.
What brands offer tires for the 2022 GMC Trucks Acadia?
Available product coverage for the 2022 GMC Trucks Acadia currently includes BFGoodrich in 255/65R17. That option is the BFG All Terrain T/A KO2, a radial tire that combines the Acadia's 17-inch fitment with an all-terrain style and raised white letter presentation.
Brand comparison only helps after the correct tire size has been confirmed, because this Acadia uses three different fitments across the lineup. A buyer with an AT4 on 17-inch wheels is shopping a different size category than a Denali or 20-inch SLE. Start with fitment, then compare brand, tire series, and sidewall character within that size.
Restoration & Appearance
How does tire construction affect the appearance of a 2022 GMC Trucks Acadia?
On a 2022 GMC Trucks Acadia, tire construction is straightforward because the applicable fitments are radial. The visible difference is less about bias-ply versus radial and more about the wheel-and-tire package itself, including sidewall height, wheel diameter, and details such as raised white letters on certain 17-inch options.
Appearance changes noticeably between the Acadia's 17-inch, 18-inch, and 20-inch setups, even when the overall tire diameter stays in a similar range. That is why the exact trim and wheel package matter when replacing tires. Matching the existing size preserves the vehicle's intended stance more closely than choosing by tread style alone.
Does correct tire fitment matter for the appearance of a 2022 GMC Trucks Acadia?
Correct tire fitment has a direct effect on how a 2022 GMC Trucks Acadia sits and looks. The vehicle uses three different size-and-wheel combinations, and each creates a different visual balance between sidewall height and wheel presence. Using the proper size keeps the trim's wheel package in proportion.
That matters whether the goal is to maintain a rugged AT4 look or the larger-wheel presentation used on other Acadia trims. Even small fitment changes can alter how the wheel openings appear and how much sidewall is visible. Checking the installed wheel diameter first is the simplest way to keep the replacement tire visually consistent.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 GMC Trucks Acadia?
Modifications can absolutely affect tire fitment on a 2022 GMC Trucks Acadia. Wheel changes, different offsets, suspension lowering or lifting, and body or fender alterations can all change the space available for 255/65R17, 235/65R18, or 235/55R20 tires. Even when the size sounds close, the installed package may differ from stock.
That makes clearance and wheel-spec checks important before replacement, especially on a used vehicle. Looking at the current tire sidewall, measuring wheel diameter, and verifying wheel width can reveal whether the Acadia still follows its original trim-based fitment. Steering clearance and full-turn interference are also worth checking after any change.
What should I inspect before driving a 2022 GMC Trucks Acadia on new tires?
Before driving a 2022 GMC Trucks Acadia on new tires, inspect wheel diameter, wheel condition, lug hardware, and the installed tire size to make sure the setup matches the trim. It also helps to look over the suspension and alignment condition, since worn components can affect how a new set of tires behaves on the road.
Air pressure should be set correctly, and the tires should be checked for even seating, proper clearance, and any contact points near the strut, inner liner, or fender edge. A short local drive followed by another visual inspection is a smart final step. That process can catch rubbing, vibration, or pressure loss early.
How often should tires on a 2022 GMC Trucks Acadia be inspected?
Tires on a 2022 GMC Trucks Acadia should be inspected regularly rather than only when replacement time arrives. A visual check for tread wear, cuts, bulges, cracking, punctures, and uneven wear patterns helps catch problems early. Pressure checks matter too, since underinflation and overinflation can both change tire wear and road behavior.
A practical routine is to inspect the tires monthly and again before longer trips. Owners should also pay attention after seasonal temperature swings or any curb impact, pothole strike, or wheel change. Since the Acadia uses trim-specific sizes, it is also worth confirming that all four tires still match the intended fitment for the wheel package.
