The 2017 GMC Trucks Canyon sits in the midsize pickup segment with a blend of daily usability and real truck capability, which is why tire selection matters more than simply matching a nameplate. Depending on trim, the Canyon uses several different radial tire sizes across 16-, 17-, 18-, and 20-inch wheel fitments. That makes this a vehicle where identifying the exact sub-model and wheel setup comes first, especially because Base, SL, Denali, SLE, and SLT configurations do not all share the same size. Once the fitment is confirmed, the decision shifts to tire style, load-oriented specifications, and whether an all-terrain look suits the truck’s intended use.
Which Tire Size Is Right for The 2017 GMC Trucks Canyon
The 2017 GMC Trucks Canyon uses five primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All of them are radial metric sizes, but they are spread across 16-, 17-, 18-, and 20-inch rims, so the first step is confirming both the trim level and the wheels currently on the truck before choosing a tire.
265/70R16 is a metric radial size in which 265 identifies the nominal section width in millimeters, 70 is the aspect ratio, and 16 is the rim diameter in inches. On the 2017 GMC Trucks Canyon, this size is used on 16-inch wheel fitments and serves Base and SL applications. Available product coverage in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, giving it a more truck-oriented presentation. This size is worth evaluating carefully if the Canyon is expected to balance everyday driving with a more rugged visual style or light-duty trail use.
255/55R20 is a metric radial size that uses a 255-millimeter nominal section width, a 55-series profile, and a 20-inch rim diameter. On the 2017 GMC Trucks Canyon, this size belongs to the Denali configuration and reflects a different wheel-and-tire package than the smaller-diameter setups used elsewhere in the range. Its lower profile and larger rim diameter make exact wheel confirmation especially important before any replacement decision is made. This is the size to focus on when preserving the truck’s existing Denali stance and avoiding confusion with the 16-, 17-, and 18-inch Canyon fitments.
255/65R17 is a metric radial size where 255 is the nominal section width in millimeters, 65 is the aspect ratio, and 17 is the rim diameter in inches. On the 2017 GMC Trucks Canyon, this size appears within the SLE range rather than across every sub-model, so it should be matched to the truck’s exact configuration. Available product coverage includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, which gives this fitment an all-terrain character. It is a useful choice to examine when the truck already runs 17-inch wheels and a more utility-focused tire style is part of the goal.
265/60R18 is a metric radial tire size with a 265-millimeter nominal section width, a 60-series profile, and an 18-inch rim diameter. It applies to certain 2017 GMC Trucks Canyon configurations, including the SLT and some SLE applications, so it should not be treated as universal across the model line. This size occupies a middle ground within the Canyon range, pairing a substantial section width with a larger wheel than the 16- and 17-inch setups. It deserves a close look when replacing tires on an 18-inch Canyon because wheel diameter and trim-specific fitment are both central to the decision.
265/65R17 is a metric radial size in which 265 denotes the nominal section width in millimeters, 65 is the aspect ratio, and 17 identifies the rim diameter. On the 2017 GMC Trucks Canyon, this size is used on certain SLE configurations, making it one of several trim-dependent fitments rather than a model-wide standard. Its dimensions place it alongside the other truck-oriented Canyon sizes, but it still needs to be matched to the correct wheel package. This size becomes the right one to evaluate only after confirming that the truck’s SLE setup uses the wider 265-section 17-inch fitment rather than the alternate 255/65R17.
Tire fitment on the 2017 GMC Trucks Canyon varies by sub-model, and some trims share a size while others use completely different wheel diameters. Checking the exact trim matters here because Base, SL, Denali, SLE, and SLT do not all use the same tire package.

2017 GMC Trucks Canyon Base
The 2017 GMC Trucks Canyon Base uses the 265/70R16 radial tire size. That keeps the selection focused on confirming the existing 16-inch wheel setup and then choosing the tire style and specification that best suit how the truck is actually used.
The 2017 GMC Trucks Canyon Denali uses the 255/55R20 radial size, which stands apart from the smaller-diameter fitments used on other Canyon trims. Tire selection starts with confirming that the truck still carries its 20-inch wheel package before comparing replacement options.
The 2017 GMC Trucks Canyon SL shares the 265/70R16 radial size with the Base model. That makes fitment relatively straightforward, with the main decision shifting from size identification to choosing the right tire type and appearance for the truck’s intended use.
The 2017 GMC Trucks Canyon SLE is the trim where fitment needs the closest verification, because it can use 255/65R17, 265/60R18, or 265/65R17 radial tires. Matching the tire to the actual wheel diameter on the truck is essential before comparing tread style, load-oriented specifications, or overall tire character.
The 2017 GMC Trucks Canyon SLT uses the 265/60R18 radial tire size. That points the buying decision toward the 18-inch wheel setup specifically, so replacement choices should be evaluated around that fitment rather than the 16-, 17-, or 20-inch Canyon sizes.
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.

Tire Size & Fitment
What tire size fits a 2017 GMC Trucks Canyon?
The 2017 GMC Trucks Canyon uses more than one tire size depending on sub-model. The fitments are 265/70R16, 255/55R20, 255/65R17, 265/60R18, and 265/65R17, and all are radial sizes tied to specific trim and wheel combinations rather than one universal setup.
The practical first step is identifying the exact Canyon trim and confirming the wheels currently on the truck. Base and SL use 265/70R16, Denali uses 255/55R20, SLT uses 265/60R18, and SLE can use three different sizes, so the same model year Canyon does not always take the same tire.
What size rim does a 2017 GMC Trucks Canyon use?
A 2017 GMC Trucks Canyon can use 16-inch, 17-inch, 18-inch, or 20-inch rims depending on sub-model and tire package. Those rim diameters correspond to the five primary tire sizes used across the Canyon range, so wheel diameter is a core part of selecting the correct replacement tire.
Checking the actual wheel on the truck matters because trim names alone do not cover every possible change made over time. The SLE in particular can use more than one size, so it helps to confirm the existing wheel diameter before comparing tires, especially if the truck has aftermarket wheels or a changed stance.
Do all 2017 GMC Trucks Canyon sub-models use the same tire size?
No, the 2017 GMC Trucks Canyon sub-models do not all use the same tire size. Base and SL share 265/70R16, Denali uses 255/55R20, SLT uses 265/60R18, and SLE can use 255/65R17, 265/60R18, or 265/65R17 depending on its wheel setup.
That variation means a Canyon owner should confirm the exact sub-model and wheel package before replacing tires. It is easy to assume that one Canyon size fits every trim, but the spread from 16-inch through 20-inch rims changes the decision completely and can affect appearance, clearance, and wheel compatibility.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 GMC Trucks Canyon?
Start with the correct primary tire size for the exact 2017 GMC Trucks Canyon trim and wheel diameter, since this model uses several different fitments. After that, compare construction details, load-related specifications, rim-width compatibility, and whether the tire’s overall character matches how the truck is driven.
A Canyon used mainly on pavement may call for a different tire presentation than one expected to handle gravel, weather, or occasional trail duty. It also helps to confirm whether the truck still has its original wheel size, because selecting by appearance alone can lead to the wrong 16-, 17-, 18-, or 20-inch fitment.
What sidewall styles are available for 2017 GMC Trucks Canyon tires?
Among the currently covered 2017 GMC Trucks Canyon product options, the available sidewall style is RWL, or raised white letter. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options offered in the applicable 265/70R16 and 255/65R17 sizes.
Sidewall style affects the truck’s visual character as much as its mechanical fitment. Raised white letters create a more traditional all-terrain look, so they make the most sense when that presentation suits the Canyon’s intended use, while the core fitment check should still stay focused on size, wheel diameter, and rim-width compatibility.
What brands offer tires for the 2017 GMC Trucks Canyon?
The currently covered tire options for the 2017 GMC Trucks Canyon come from BFGoodrich. In the applicable sizes with product coverage, the BFGoodrich offering is the All-Terrain T/A KO2, a radial all-terrain tire with raised white letter sidewalls.
Brand alone should not be the only deciding factor. The more important question is whether the available tire matches the correct Canyon fitment and whether its load-capacity, rim-width range, and overall style suit the truck’s actual role, especially on trims that already have very different wheel-and-tire packages.
Restoration & Appearance
Which tire should I choose for a period-style 2017 GMC Trucks Canyon?
A period-style approach on a 2017 GMC Trucks Canyon usually starts with retaining the correct trim-specific tire size and wheel diameter rather than changing the truck’s proportions. Keeping the Base, SL, Denali, SLE, or SLT fitment in its proper size family preserves the stance and overall presentation more faithfully.
Appearance then comes down to the type of tire you want the Canyon to project. An all-terrain design with raised white letters gives a more rugged visual statement, while the key fitment discipline remains the same: verify the actual wheel package first and avoid assuming one Canyon trim’s size belongs on another.
Does correct tire fitment matter for a 2017 GMC Trucks Canyon restoration?
Yes, correct tire fitment matters on a 2017 GMC Trucks Canyon restoration because the model uses several distinct wheel-and-tire combinations across its trim range. Using the proper size for the truck’s actual configuration helps maintain the intended stance, sidewall profile, and overall relationship between tire and wheel.
Owners pursuing a more exact restoration should also verify the truck’s original wheel package through vehicle-specific references before choosing among available tire styles. Even on a newer collector-era truck, changing from a 16-inch or 17-inch setup to an 18-inch or 20-inch package can alter the appearance as much as the fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 GMC Trucks Canyon?
Yes, modifications can affect tire fitment on a 2017 GMC Trucks Canyon even when the nominal tire size appears correct. Aftermarket wheels, wheel offset changes, suspension lifts or drops, and body alterations can all change the space available for the tire and the way it sits within the wheel opening.
A Canyon with changed wheels or suspension should be checked for actual rim diameter, rim width, and clearance at steering lock and through suspension travel. That matters even more on trims like the SLE, where more than one factory tire size was used, because a modification can blur the original fitment reference point.
What should I inspect before driving a 2017 GMC Trucks Canyon on new tires?
Before driving a 2017 GMC Trucks Canyon on new tires, inspect inflation pressure, lug torque, visible sidewall condition, and basic tread seating, and make sure the tires match the truck’s actual wheel diameter and trim-specific size. It also helps to look over the wheels themselves for damage or previous repair issues.
A short, careful road test is the right next step so any rubbing, pull, vibration, or air-loss issue can be caught early. Trucks that have sat for long periods or changed hands recently also deserve a quick suspension and steering check, since worn components can affect how even a correctly sized tire behaves.
What should I check before a longer drive in a 2017 GMC Trucks Canyon?
Before a longer drive in a 2017 GMC Trucks Canyon, confirm that the truck is wearing the correct tire size for its trim and wheel package, then check inflation pressure, tread condition, sidewall integrity, and any signs of cuts, bulges, or slow air loss. A quick look at wheel condition is worthwhile too.
Longer trips put more focus on consistency, so recheck the tires after the first few miles if they were recently installed. It is also smart to pay attention to vibration, steering feel, and any contact noise, especially if the Canyon has aftermarket wheels or if the current setup differs from its original trim-level configuration.
