The 2015 GMC Trucks Canyon marked the return of GMC’s midsize pickup in a form that balanced everyday drivability with real truck utility. Buyers could choose from work-oriented and more upscale trims, so tire fitment depends heavily on the exact sub-model and wheel package. This Canyon uses radial tires in three different metric sizes: 265/70R16, 255/65R17, and 265/60R18. Available choices here center on BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls in the 16-inch and 17-inch fitments. The key step is matching the tire to the truck’s specific trim and wheel diameter before comparing appearance, load capacity, and intended road use.
Which Tire Size Is Right for The 2015 GMC Trucks Canyon
The 2015 GMC Trucks Canyon uses three primary tire sizes, and the correct one depends on the truck’s exact sub-model and wheel diameter. All three are metric radial fitments, but they are tied to different 16-inch, 17-inch, and 18-inch wheel setups. Before choosing a tire, identify whether the truck is a Base, SL, SLE, or SLT and confirm the wheel diameter currently on the vehicle.
265/70R16 is a metric radial size in which 265 denotes the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 2015 GMC Trucks Canyon, this size is used on 16-inch wheel applications rather than across every trim. Available selections in this fitment include a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. This size is the one to evaluate when the truck has the 16-inch setup and the goal is to keep the correct wheel diameter while comparing truck-style tire character and rim-width compatibility.
255/65R17 is a metric radial size that uses a 255-millimeter nominal section width, a 65-series profile, and a 17-inch rim diameter. For the 2015 GMC Trucks Canyon, this size belongs to a specific trim application and should not be treated as universal across all sub-models. BFGoodrich offers this fitment in the All-Terrain T/A KO2 series with raised white letter sidewalls, giving it a more traditional truck presentation. It is the right size to consider when the Canyon is equipped with the 17-inch wheel package and the buyer wants to compare load capacity, rim-width range, and all-terrain-style appearance.
265/60R18 is a metric radial size with a 265-millimeter nominal section width, a 60-series profile, and an 18-inch wheel diameter. On the 2015 GMC Trucks Canyon, this fitment is tied to the 18-inch setup, so wheel confirmation matters before treating it as an option. Its lower profile relative to the other Canyon sizes also means it carries a distinct look that matches the larger wheel package. This is the size to verify when selecting tires for an SLT-equipped truck or any Canyon currently running 18-inch wheels and stock-style overall fitment.
Tire fitment on the 2015 GMC Trucks Canyon varies by sub-model, so the correct choice starts with identifying the trim level and wheel diameter. Base and SL models share one size, while SLE and SLT move to different wheel and tire combinations.

2015 GMC Trucks Canyon Base
The 2015 GMC Trucks Canyon Base uses the 265/70R16 radial fitment on a 16-inch wheel. That makes tire selection more straightforward, with the main focus shifting to choosing the right product type and confirming the truck still has its intended wheel setup.
The 2015 GMC Trucks Canyon SL shares the 265/70R16 radial tire size with the Base model. Owners should still confirm the wheel diameter on the truck, then compare available options by tread style, sidewall presentation, and rim-width compatibility.
The 2015 GMC Trucks Canyon SLE uses the 255/65R17 radial size, which places it on a different wheel package from the 16-inch trims. That makes trim confirmation important before purchase, especially if the truck has changed wheels at some point in its life.
The 2015 GMC Trucks Canyon SLT uses the 265/60R18 radial size on an 18-inch wheel. Tire selection starts with confirming that larger wheel setup, then checking overall fitment carefully if the truck has aftermarket wheels or suspension changes.
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 2015 GMC Trucks Canyon Tires for Sale
Available Canyon tire choices focus on BFGoodrich All-Terrain T/A KO2 fitments in 265/70R16 and 255/65R17. Both use radial construction with raised white letter sidewalls, while key comparison points include rim-width range, load capacity, and overall tire weight.
2015 GMC Trucks Canyon tire questions usually come down to trim-specific size selection, matching the correct wheel diameter, and comparing available radial truck tires by sidewall style, load specification, and intended use.
Tire Size & Fitment
What tire size fits a 2015 GMC Trucks Canyon?
The 2015 GMC Trucks Canyon uses three possible tire sizes: 265/70R16, 255/65R17, and 265/60R18. The correct fitment depends on the truck’s sub-model and wheel package, with Base and SL using 265/70R16, SLE using 255/65R17, and SLT using 265/60R18.
The most important step is confirming the trim and the wheel diameter actually on the truck today. Many pickups receive wheel changes during ownership, so the safest approach is to match the tire size to the current wheel, then check width, clearance, and intended use before choosing a specific tire.
What size rim does a 2015 GMC Trucks Canyon use?
A 2015 GMC Trucks Canyon can use 16-inch, 17-inch, or 18-inch rims depending on the sub-model. The 265/70R16 fitment uses a 16-inch rim, 255/65R17 uses a 17-inch rim, and 265/60R18 uses an 18-inch rim.
Rim diameter is the first thing to verify because a tire must match the wheel’s diameter exactly. Once that is confirmed, look at the wheel width as well, especially when comparing all-terrain tires, since rim-width compatibility helps determine whether a particular tire is suitable for the truck’s setup.
Do all 2015 GMC Trucks Canyon sub-models use the same tire size?
No. The 2015 GMC Trucks Canyon uses different tire sizes across its sub-model range. Base and SL models use 265/70R16, the SLE uses 255/65R17, and the SLT uses 265/60R18.
That variation means trim identification matters before comparing tires. It also means the truck’s wheel package has to be part of the decision, since the 16-inch, 17-inch, and 18-inch fitments are not interchangeable simply because they belong to the same model year and nameplate.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 GMC Trucks Canyon?
Start with the correct size for the truck’s trim and wheel diameter, since the 2015 GMC Trucks Canyon uses three different fitments. From there, compare construction, rim-width compatibility, load capacity, weight, and how the tire’s tread and sidewall style suit the way the truck is driven.
A Canyon used mostly on pavement may call for a different emphasis than one expected to handle rougher surfaces or a more truck-oriented look. It also helps to confirm whether the truck still has its original wheel package, because aftermarket wheels can change what tire dimensions make practical sense.
What sidewall styles are available for 2015 GMC Trucks Canyon tires?
The available 2015 GMC Trucks Canyon products in these fitments use RWL sidewalls, which means raised white letter styling. That gives the tire a more traditional light-truck appearance than a plain blackwall presentation and can matter to buyers who want a more assertive visual look.
Sidewall style is mostly an appearance decision, but it should still be made after size and wheel compatibility are confirmed. Once the correct fitment is established, raised white letters become part of the overall look of the truck, especially on a Canyon with stock-style wheels and a visible sidewall profile.
What brands offer tires for the 2015 GMC Trucks Canyon?
BFGoodrich is available in the current product selection for applicable 2015 GMC Trucks Canyon sizes. The BFGoodrich offering appears in the All-Terrain T/A KO2 series for both 265/70R16 and 255/65R17 fitments, giving buyers a consistent all-terrain style within those wheel packages.
Brand choice is only one part of the decision. The more important comparison points are whether the tire matches the truck’s trim-specific size, whether the wheel width falls within the tire’s approved range, and whether the load specification and overall character suit the Canyon’s intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2015 GMC Trucks Canyon?
A period-style approach on a 2015 GMC Trucks Canyon starts with keeping the correct trim-specific tire size and wheel diameter. Since this truck uses modern metric radial sizes, appearance is shaped more by the wheel package, sidewall presentation, and tire character than by choosing between older sizing conventions.
Raised white letter all-terrain styling can suit a Canyon with a more truck-focused look, especially in the 16-inch and 17-inch fitments shown here. Buyers concerned with exact original appearance should also compare the truck against window-sticker records, dealer literature, or marque-specific references before making a final choice.
Does correct tire fitment matter for a 2015 GMC Trucks Canyon restoration?
Yes, correct tire fitment matters because the 2015 GMC Trucks Canyon used different sizes across different trims and wheel packages. A restoration-oriented truck looks more coherent when the tire size matches the proper 16-inch, 17-inch, or 18-inch setup instead of using a random substitute that changes its stance.
Appearance is only part of the reason. Correct fitment also helps preserve proper wheel-to-tire relationship, steering clearance, and the overall presentation intended for that trim level. Even on a newer collector pickup, it is worth confirming both the wheel diameter and the trim before selecting replacement tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 GMC Trucks Canyon?
Yes. Wheel swaps, suspension changes, leveling kits, lowering, and offset changes can all affect tire fitment on a 2015 GMC Trucks Canyon. Even when the truck started with one of the original sizes, later modifications can change the space available around the fenders, steering components, and suspension.
That is why the current setup should be checked before treating any stock-size tire as an automatic answer. Confirm wheel diameter first, then verify wheel width, clearance at full steering lock, and any signs that the truck’s ride height or suspension geometry has changed from its original configuration.
What should I inspect before driving a 2015 GMC Trucks Canyon on new tires?
Inspect the wheels for correct diameter and sound condition, and make sure the new tires match the truck’s actual fitment. It is also smart to check inflation pressure, lug hardware, valve stems, and for any interference around brakes, suspension parts, and fender openings before regular road use.
A short initial drive can reveal rubbing, vibration, or steering issues that are easier to correct early. After that, recheck pressure and inspect the tread and sidewalls periodically, especially if the truck sees mixed-use driving or carries loads that make tire condition and inflation especially important.
How often should tires on a 2015 GMC Trucks Canyon be inspected?
Tires on a 2015 GMC Trucks Canyon should be inspected regularly, not just when they look low or worn. Routine checks should cover air pressure, tread wear, cuts, bulges, cracking, and any uneven wear pattern that might suggest alignment, wheel, or suspension issues.
Inspection becomes even more important when the truck is used infrequently, since age and storage conditions can affect tires even when tread depth still looks acceptable. Looking over the tires before longer drives and at normal service intervals helps catch problems early and supports safer, more predictable road use.
