The 2017 GMC Trucks Acadia arrived as a more maneuverable midsize crossover, blending family-duty comfort with a broader range of trim levels and wheel packages than many earlier truck-based SUVs. That matters when replacing tires, because this Acadia does not rely on one universal size across the lineup. Depending on sub-model, it uses 245/65R17, 235/65R18, or 235/55R20 radial tires, each tied to a different wheel diameter and overall stance. The main decision is not simply choosing a brand, but confirming the exact trim and wheel setup first. That becomes especially important on vehicles that may have seen wheel upgrades or other changes since new.
Which Tire Size Is Right for The 2017 GMC Trucks Acadia
Three tire sizes apply to the 2017 GMC Trucks Acadia, and they vary by sub-model and wheel diameter rather than by a simple one-size-fits-all setup. The first step is confirming the exact trim and whether the vehicle is on 17-inch, 18-inch, or 20-inch wheels, because that determines whether 245/65R17, 235/65R18, or 235/55R20 is the correct radial fitment.
A 235/55R20 tire uses a 235-millimeter section width, a 55-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2017 GMC Trucks Acadia, this size belongs to trims equipped with the larger 20-inch wheel package, giving tire selection a strong wheel-confirmation component before anything else. The lower-profile sidewall compared with the other Acadia sizes also makes it important to match the vehicle's actual wheel setup rather than choosing by appearance alone. This size is the right one to evaluate when the vehicle is already configured around 20-inch wheels.
A 245/65R17 tire is a metric radial size with a 245-millimeter section width, a 65-series aspect ratio, and a 17-inch rim diameter. This size appears on Acadia configurations using the 17-inch wheel, including trims where tire choice starts with confirming whether the vehicle stayed with its original wheel diameter. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter styling and a 7.0 to 8.0 inch rim-width range. It is the size to review carefully if the Acadia sees mixed on-road use and has the factory-type 17-inch wheel format.
A 235/65R18 tire combines a 235-millimeter section width with a 65-series profile, radial construction, and an 18-inch rim diameter. For the 2017 GMC Trucks Acadia, this size serves trims that sit between the 17-inch and 20-inch wheel packages, so the key issue is verifying the actual wheel diameter on the vehicle. Its profile and wheel pairing are distinct from both 245/65R17 and 235/55R20, which means it should be treated as its own fitment rather than as a close-enough substitute. This is the size to select when the Acadia is equipped with 18-inch wheels and corresponding trim fitment.
Tire fitment on the 2017 GMC Trucks Acadia depends on the exact sub-model, and some trims use more than one size. Checking the trim badge and the wheel diameter matters before choosing a tire, especially on SLE and SLT models that can appear with different wheel setups.

2017 GMC Trucks Acadia Denali
The 2017 GMC Trucks Acadia Denali uses the 235/55R20 radial size, tying it to the 20-inch wheel setup rather than the taller-profile 17-inch or 18-inch options. Tire selection here centers on confirming that the vehicle still wears the correct wheel diameter and choosing a tire that suits the intended balance of appearance and road use.
The 2017 GMC Trucks Acadia SL uses the 245/65R17 radial size, making the 17-inch wheel the starting point for any replacement search. That keeps the fitment straightforward, but it is still worth checking whether the vehicle has remained on its original wheel format before selecting a new tire.
The 2017 GMC Trucks Acadia SLE can use either 235/65R18 or 245/65R17, so identifying the actual wheel and tire setup on the vehicle is essential. Tire choice for an SLE is less about trim name alone and more about confirming whether it carries the 17-inch or 18-inch fitment.
The 2017 GMC Trucks Acadia SLT can be fitted with either 235/55R20 or 235/65R18, depending on wheel configuration. That makes wheel diameter the deciding factor, and owners should verify the current setup carefully before comparing tires or assuming all SLT models use the same size.
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.
Best 2017 GMC Trucks Acadia Tires for Sale
Available product choice for the 2017 GMC Trucks Acadia is centered on 245/65R17, with a BFGoodrich All-Terrain T/A KO2 option that combines radial construction, raised white letter sidewalls, and 17-inch fitment for vehicles using that wheel size.
Owners of a 2017 GMC Trucks Acadia usually need to sort out trim-specific tire size, wheel diameter, and current vehicle setup first. The questions below focus on fitment, product choice, sidewall style, and practical checks before putting the vehicle back on the road.
Tire Size & Fitment
What tire size fits a 2017 GMC Trucks Acadia?
The 2017 GMC Trucks Acadia uses three radial tire sizes: 245/65R17, 235/65R18, and 235/55R20. The correct one depends on the sub-model and wheel package, so there is not one universal tire size for every Acadia in this model year.
The practical next step is to confirm the exact trim and the wheel diameter already on the vehicle. An SL may use 245/65R17, while Denali models use 235/55R20, and SLE or SLT versions can vary. Checking the existing tire sidewall and wheel size helps prevent choosing a tire that matches the model name but not the actual setup.
What size rim does a 2017 GMC Trucks Acadia use?
A 2017 GMC Trucks Acadia can use 17-inch, 18-inch, or 20-inch rims, depending on sub-model and configuration. Those rim diameters correspond to 245/65R17, 235/65R18, and 235/55R20 tire sizes.
Rim diameter should be confirmed before comparing any replacement tire, because each Acadia size is tied to a different wheel. A tire built for a 17-inch rim cannot be mounted on an 18-inch or 20-inch wheel, even if the vehicle itself is the same year and model. That makes the wheel already on the vehicle the first fitment checkpoint.
Why does the 2017 GMC Trucks Acadia have more than one tire size?
The 2017 GMC Trucks Acadia has more than one tire size because different sub-models were equipped with different wheel diameters and tire profiles. The lineup spans 17-inch, 18-inch, and 20-inch wheel fitments, so tire sizing changes with trim and wheel package rather than remaining constant across the range.
That variation means buyers should not rely on the Acadia name alone when ordering tires. SLE and SLT models are especially important to verify because they can appear with more than one size. Reading the current sidewall size and checking the wheel diameter gives a much cleaner starting point than trying to choose by trim description only.
Choosing the Right Tire
What should I consider when choosing a 245/65R17 tire for a 2017 GMC Trucks Acadia?
Start by confirming that the 2017 GMC Trucks Acadia actually uses the 245/65R17 size, since other trims use 18-inch or 20-inch fitments instead. Once the size is confirmed, compare construction, sidewall presentation, rim-width compatibility, load capacity, and how the tire's overall character matches the vehicle's intended use.
One available 245/65R17 option is a BFGoodrich All-Terrain T/A KO2 with radial construction, raised white letter sidewalls, a 7.0 to 8.0 inch rim-width range, and a maximum load capacity of 2,405 lbs @ 65 psi. Those details matter most when the Acadia sees mixed driving conditions and the owner wants a tire that matches both wheel fitment and use.
What sidewall styles are available for 2017 GMC Trucks Acadia tires?
For the 2017 GMC Trucks Acadia products available here, the visible sidewall style is RWL, or raised white letter. That style appears on the available 245/65R17 BFGoodrich All-Terrain T/A KO2 and gives the tire a more assertive look than a plain black sidewall presentation.
Sidewall style is an appearance decision after the correct size has been confirmed, not a substitute for fitment. A raised white letter tire can change the vehicle's visual character, so it is worth deciding whether the goal is a more truck-oriented look or a more understated presentation. The first filter still needs to be the Acadia's actual tire size and wheel diameter.
What brands offer tires for the 2017 GMC Trucks Acadia?
BFGoodrich is represented among the available tires for the 2017 GMC Trucks Acadia, specifically in the 245/65R17 size. The current product offering shown here centers on the All-Terrain T/A KO2, a radial tire with raised white letter styling for 17-inch wheel applications.
Brand becomes meaningful only after the exact Acadia fitment has been nailed down, because this model year uses multiple sizes across different trims. Once the size is verified, compare the brand's available tire series, sidewall treatment, rim-width specification, and load details rather than choosing on the badge alone. That approach keeps the purchase aligned with both fitment and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2017 GMC Trucks Acadia?
A period-style approach on a 2017 GMC Trucks Acadia starts with keeping the correct original size format for the vehicle's trim and wheel diameter: 245/65R17, 235/65R18, or 235/55R20. Since this is a modern crossover rather than a vintage collector car, the visual goal is usually preserving the vehicle's intended stance more than recreating a special sidewall era.
That makes wheel confirmation especially important on used examples that may have been changed over time. Staying with the size already appropriate to the trim keeps the proportions closest to the Acadia's original presentation. If appearance matters as much as function, compare the tire's sidewall style and overall look after the fitment basics are settled.
Does correct tire fitment matter for a 2017 GMC Trucks Acadia restoration?
Correct tire fitment matters because the 2017 GMC Trucks Acadia uses different wheel diameters and tire profiles across the lineup. Using the proper size helps preserve the vehicle's intended stance, wheel-to-tire proportion, and general visual character, especially on a restoration-minded project where details are part of the finished result.
Appearance is only one reason to stay attentive to fitment. The wrong size can also complicate wheel compatibility and clearance, particularly if the vehicle has changed hands or received aftermarket wheels. Even on a newer restoration project, matching the tire to the actual trim and wheel setup is one of the cleanest ways to keep the vehicle looking and functioning as expected.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 GMC Trucks Acadia?
Yes, modifications can affect tire fitment on a 2017 GMC Trucks Acadia. Aftermarket wheels, suspension changes, ride-height adjustments, or body alterations can change the clearance and wheel specifications that the original 245/65R17, 235/65R18, or 235/55R20 sizes were designed around.
That is why the current setup should be checked before buying replacement tires. Wheel diameter is the first checkpoint, followed by wheel width, then clearance at full steering lock and through suspension travel. Even when the tire size on paper matches an Acadia application, changes made over the years can turn a normal replacement decision into a custom-fitment situation.
What should I inspect before driving a 2017 GMC Trucks Acadia on new tires?
Before driving a 2017 GMC Trucks Acadia on new tires, inspect the wheel diameter, confirm the tire size matches the trim, and make sure the tires are properly inflated. It is also smart to look over the wheels for damage and verify that the tires seat correctly and clear suspension, steering, and body components.
A short road test should follow any tire installation, with attention to vibration, rubbing, pulling, or uneven behavior. Rechecking inflation after initial use is a good habit, especially on a vehicle with multiple possible wheel packages. Taking a few minutes to confirm the basics helps catch installation or fitment issues before they become harder to trace.
How often should tires on a 2017 GMC Trucks Acadia be inspected?
Tires on a 2017 GMC Trucks Acadia should be inspected regularly, not just when tread looks worn. Frequent pressure checks and routine visual inspections for cuts, cracking, bulges, uneven wear, or air loss are especially useful on a crossover that may alternate between daily driving and longer road trips.
Inspection matters even more when the vehicle has changed wheel sizes or sees mixed-use driving. A quick look before a trip can reveal sidewall damage, abnormal wear patterns, or clearance issues that did not show up earlier. Consistent inspection helps protect both tire life and fitment confidence, particularly on an Acadia that does not use the same tire size across every trim.
