The 2019 GMC Trucks Canyon sits in the modern midsize pickup segment with a mix of everyday drivability, light-truck utility, and trim-level variety that can change the truck’s stance and wheel package significantly. For Canyon owners, that makes tire selection more about confirming the exact sub-model and wheel diameter than simply matching the badge on the fender. This model uses radial tire fitments across five primary sizes, ranging from 265/70R16 up to 255/55R20. Depending on configuration, the decision may center on maintaining the truck’s original wheel-and-tire profile or choosing among available all-terrain products in the correct size. Getting that foundation right matters before comparing appearance, load capability, or road-use priorities.
Which Tire Size Is Right for The 2019 GMC Trucks Canyon
The 2019 GMC Trucks Canyon uses five primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. These are all radial fitments, but they span 16-inch, 17-inch, 18-inch, and 20-inch rims, so the first step is confirming the truck’s current wheel setup. Once that is settled, the next decision is whether to stay with the original size profile for the trim or compare available tire choices within that size.
255/65R17 is a metric radial size in which 255 identifies the nominal section width in millimeters, 65 is the aspect ratio, R marks radial construction, and 17 is the wheel diameter in inches. On the 2019 GMC Trucks Canyon, this size is used on certain 17-inch-wheel configurations rather than across the full model line. Available product coverage in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. It is a useful choice to evaluate when the truck is equipped with the correct 17-inch wheels and an all-terrain light-truck look is part of the goal.
265/65R17 follows the same metric radial format, with a 265-millimeter nominal width, a 65-series profile, radial construction, and a 17-inch rim diameter. For the 2019 GMC Trucks Canyon, this size appears on specific sub-model configurations and should not be assumed for every truck wearing 17-inch wheels. Product choice in this exact size should be guided by the truck’s trim, current wheel setup, and intended road or trail use. It makes sense to consider this size when preserving the Canyon’s original fitment balance on a configuration that was built around a wider 17-inch tire.
265/70R16 is a metric radial size that combines a 265-millimeter nominal width with a 70-series profile on a 16-inch wheel. This is one of the Canyon’s primary radial fitments and is associated with 16-inch-wheel sub-models, making wheel diameter confirmation especially important before replacement. In this size, BFGoodrich offers the All-Terrain T/A KO2 with raised white letter sidewalls, giving the tire a more traditional light-truck presentation. It is the right size to review when the truck still runs its original 16-inch wheel package and the owner wants a fitment that supports pickup use without moving to a different rim diameter.
255/55R20 is a metric radial size with a 255-millimeter nominal width, a 55-series sidewall profile, and a 20-inch wheel diameter. On the 2019 GMC Trucks Canyon, this size belongs to a specific upper-trim wheel package rather than to the Canyon range as a whole. Its lower-profile format gives it a different fitment character than the 16-inch and 17-inch truck-oriented sizes used elsewhere in the lineup. This is the size to confirm when the truck carries factory-style 20-inch wheels and the goal is to keep the correct wheel-and-tire proportion for that configuration.
265/60R18 uses a 265-millimeter nominal width, a 60-series aspect ratio, radial construction, and an 18-inch rim diameter. Within the 2019 GMC Trucks Canyon range, it applies to certain 18-inch-wheel sub-models, so it should be matched to the truck’s actual trim and wheel package rather than chosen by model name alone. This size sits between the taller-sidewall 16-inch and 17-inch fitments and the lower-profile 20-inch option in the Canyon lineup. It is the size to consider when keeping an 18-inch setup in proper proportion and avoiding unnecessary wheel-diameter changes.
Tire fitment for the 2019 GMC Trucks Canyon varies by sub-model, and several trims use different wheel diameters. Checking the exact trim name matters because the Canyon range spans 16-inch, 17-inch, 18-inch, and 20-inch tire packages rather than one universal setup.

2019 GMC Trucks Canyon All Terrain
The 2019 GMC Trucks Canyon All Terrain uses 17-inch radial fitments and can be found with either 255/65R17 or 265/65R17. That makes wheel and existing tire confirmation important before replacement, especially when choosing between maintaining the truck’s current profile and moving into a specific all-terrain product.
The 2019 GMC Trucks Canyon Base uses a 265/70R16 radial tire on a 16-inch wheel package. Tire selection here is more straightforward, with the main focus shifting from trim identification to matching the correct size and confirming wheel compatibility before installation.
The 2019 GMC Trucks Canyon Denali uses the 255/55R20 radial size, tied to a 20-inch wheel setup. That places the emphasis on preserving the proper rim diameter and overall profile rather than treating the truck like lower-trim Canyon models that use taller-sidewall fitments.
The 2019 GMC Trucks Canyon SL uses the same 265/70R16 radial size found on certain other 16-inch-wheel configurations. For this sub-model, the key step is confirming that the truck still carries its correct wheel package, then comparing tire choices within that exact size.
The 2019 GMC Trucks Canyon SLE has the widest fitment spread in the lineup, using 255/65R17, 265/65R17, or 265/60R18 depending on configuration. Selecting tires for an SLE starts with identifying the truck’s actual wheel diameter and present size, since the trim name alone does not narrow it to one fitment.
The 2019 GMC Trucks Canyon SLT uses the 265/60R18 radial size on an 18-inch wheel package. That makes the decision less about multiple primary sizes and more about staying with the proper 18-inch fitment and comparing tire characteristics that suit the truck’s use.
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 2019 GMC Trucks Canyon Tires for Sale
Available product coverage for the 2019 GMC Trucks Canyon centers on BFGoodrich All-Terrain T/A KO2 tires in 255/65R17 and 265/70R16. These radial options use raised white letter sidewalls and differ in rim-width compatibility, load capacity, and overall fitment by size.
Owners of a 2019 GMC Trucks Canyon usually need to sort out trim-level tire size, wheel diameter, available all-terrain options, and practical fitment checks before replacement. These FAQs focus on the Canyon’s exact sizes, sub-model differences, product selection, and road-use basics.
Tire Size & Fitment
What tire size fits a 2019 GMC Trucks Canyon?
The 2019 GMC Trucks Canyon uses five primary tire sizes: 255/65R17, 265/65R17, 265/70R16, 255/55R20, and 265/60R18. All of them are radial sizes, but they do not apply universally across the Canyon lineup because fitment changes by sub-model and wheel package.
The most important step is matching the size to the truck’s exact trim and current wheel diameter. A Base or SL model using 265/70R16 should not be treated the same as a Denali using 255/55R20, and an SLE can have more than one valid fitment depending on configuration.
What size rim does a 2019 GMC Trucks Canyon use?
A 2019 GMC Trucks Canyon can use 16-inch, 17-inch, 18-inch, or 20-inch rims, depending on sub-model and tire size. The 265/70R16 size uses a 16-inch rim, 255/65R17 and 265/65R17 use 17-inch rims, 265/60R18 uses an 18-inch rim, and 255/55R20 uses a 20-inch rim.
That spread makes wheel confirmation essential before shopping for tires. Looking only at the model name is not enough, especially on trims like the SLE or All Terrain where more than one fitment can appear, and aftermarket wheel changes can make the current setup different from the original one.
Do all 2019 GMC Trucks Canyon sub-models use the same tire size?
No, 2019 GMC Trucks Canyon sub-models do not all use the same tire size. Base and SL use 265/70R16, Denali uses 255/55R20, SLT uses 265/60R18, All Terrain uses 255/65R17 or 265/65R17, and SLE can use 255/65R17, 265/65R17, or 265/60R18.
That means trim identification is part of tire fitment, not just a background detail. The smartest approach is to confirm the sub-model, check the tire size already on the truck, and verify the wheel diameter before comparing tread style, sidewall treatment, or load-oriented specifications.
Choosing the Right Tire
What should I consider when choosing a 2019 GMC Trucks Canyon tire?
Start with the correct size for the truck’s sub-model and wheel diameter, since the 2019 GMC Trucks Canyon uses five different primary fitments. Construction is simpler here because all primary Canyon sizes are radial, so the main variables become size accuracy, intended use, and the character of the available tire.
After size is confirmed, compare details that matter to how the truck is driven, such as all-terrain tread, rim-width compatibility, load capacity, and sidewall presentation. A Canyon used for daily road driving may call for a different product emphasis than one that regularly sees gravel, trails, or heavier-duty truck use.
What sidewall styles are available for 2019 GMC Trucks Canyon tires?
Among the currently covered Canyon products, the visible sidewall style is RWL, or raised white letter. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options available in applicable Canyon sizes and gives the truck a more traditional off-road and light-truck look.
Sidewall appearance is worth considering after the fitment basics are settled. Some owners prefer the more pronounced visual character of raised white letters, while others are focused first on matching the correct size, wheel width range, and load capability for the way the truck is actually being used.
What brands offer tires for the 2019 GMC Trucks Canyon?
Current product coverage for the 2019 GMC Trucks Canyon includes BFGoodrich. The available tires are from the All-Terrain T/A KO2 series, offered in certain Canyon sizes where an all-terrain radial tire is part of the selection.
Brand choice is only one part of the decision, especially on a truck with several sub-model-specific sizes. It still makes sense to compare the exact size needed, the tire’s rim-width range, its load specification, and whether the tread and sidewall style match the Canyon’s mix of road use, utility, and appearance goals.
Restoration & Appearance
Which tire should I choose for a period-style 2019 GMC Trucks Canyon?
A period-style approach on a 2019 GMC Trucks Canyon usually means staying with the original size format and wheel diameter used by the truck’s trim rather than changing to a different profile. Since the Canyon is a modern pickup with radial primary fitments, keeping the correct size is the first step toward preserving its intended look.
Appearance choices then come down to the tire’s visual character within that size, such as an all-terrain design or raised white letter sidewall treatment. Owners seeking a highly specific showroom-era presentation should compare the truck’s current setup with window-sticker, dealer-brochure, or marque-specific reference material before making changes.
How does tire construction affect the appearance of a restored 2019 GMC Trucks Canyon?
On a 2019 GMC Trucks Canyon, construction is not a bias-ply-versus-radial issue because the primary fitments are radial throughout the lineup. The appearance difference comes more from the tire’s overall profile, tread style, and sidewall treatment within the correct size than from a change in basic construction type.
That means a 16-inch truck fitment with a taller sidewall will present differently from a 20-inch Denali fitment even when both are correct for their trims. Matching the right size to the right sub-model is the foundation, and the visible style details should be chosen only after that fitment relationship is confirmed.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 GMC Trucks Canyon?
Yes, modifications can affect tire fitment on a 2019 GMC Trucks Canyon even when the tire size itself looks close to stock. Aftermarket wheels, changes in wheel width or offset, suspension lifts or lowering, and body or fender alterations can all change clearance and the way a tire sits on the truck.
That matters even more on the Canyon because the model already spans several factory wheel diameters and profiles. A truck that left the factory with 265/70R16 may no longer have that same setup, so current wheel dimensions and clearance at full steering lock should be checked before selecting replacement tires.
What should I inspect before driving a 2019 GMC Trucks Canyon on new tires?
Before driving a 2019 GMC Trucks Canyon on new tires, inspect wheel condition, confirm the installed size matches the truck’s trim and rim diameter, and check inflation pressure carefully. Lug torque, valve condition, visible sidewall damage, and basic clearance at the suspension and fenders also deserve attention.
A short initial drive followed by a recheck is a sensible habit, especially if the truck has different wheels than it originally used. Watching for rubbing, vibration, uneven stance, or unusual air loss early on can help catch a fitment or installation issue before the Canyon is put into regular service.
How often should tires on a 2019 GMC Trucks Canyon be inspected?
Tires on a 2019 GMC Trucks Canyon should be inspected regularly, not just when tread looks worn. Pressure, tread wear pattern, cuts, punctures, bulges, and sidewall damage are all worth checking routinely, and trucks that see mixed pavement and off-road use benefit from even more frequent inspection.
Inspection intervals become especially important if the Canyon tows, carries loads, or runs all-terrain tires on rougher surfaces. Uneven wear can point to alignment, inflation, or suspension issues, and catching those signs early helps protect both the tire investment and the truck’s day-to-day road manners.
