The 2024 GMC Trucks Terrain sits in the compact SUV segment with trim levels that range from practical daily-driver duty to a more upscale Denali presentation. That matters when choosing tires, because this Terrain does not use one universal size across the lineup. Depending on sub-model, it uses 225/65R17, 225/60R18, or 235/50R19 radial tires, each tied to a specific wheel diameter. The decision here starts with confirming the exact trim and wheel setup, then narrowing the choice by tire type, sidewall presentation, and intended road use. That is especially important if the vehicle has changed wheels since new or sees mixed highway and light all-terrain use.
Which Tire Size Is Right for The 2024 GMC Trucks Terrain
Three tire sizes apply to the 2024 GMC Trucks Terrain, and the correct one depends on the exact sub-model and wheel diameter. The first step is confirming whether the vehicle uses 17-inch, 18-inch, or 19-inch wheels, since each primary size is built around a different rim diameter. Once that is settled, the decision shifts to choosing a tire that matches the Terrain's intended use, whether that means everyday road driving or a more aggressive all-terrain look and feel.
In 225/65R17, the 225 is the nominal section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. This is a modern metric radial size used on certain 2024 GMC Trucks Terrain sub-models and built around a 17-inch wheel. Available product choice in this size includes a BFGoodrich All Terrain T/A KO2 with an RBL sidewall and an all-terrain tire character. It is the right size to evaluate when the Terrain has the 17-inch setup and the owner wants to balance correct fitment with a more rugged tire style.
Fit(s): Denali, SLE Elevation Edition, SLT, and SLT Elevation Edition
Construction: Radial|Rim: 19 in
A 235/50R19 tire uses a 235-millimeter nominal section width, a 50-series profile, radial construction, and a 19-inch rim. On the 2024 GMC Trucks Terrain, this size belongs to specific trims rather than the entire model line, so it should be matched to the vehicle's actual wheel package. Its shorter profile relative to the other Terrain sizes gives it a different sizing character while staying within the model's fitment range. This is the size to confirm when the vehicle wears factory-style or replacement 19-inch wheels and trim-specific fitment is the key question.
The size 225/60R18 indicates a 225-millimeter nominal section width, a 60-series aspect ratio, radial construction, and fitment on an 18-inch wheel. On the 2024 GMC Trucks Terrain, this size is associated with a specific sub-model configuration rather than the full lineup. It sits between the 17-inch and 19-inch Terrain fitments in wheel diameter, so it should not be chosen unless the vehicle actually uses 18-inch rims. This is the size to focus on when confirming an SLT setup and comparing replacement tires that preserve the intended wheel-and-tire relationship.
Tire fitment on the 2024 GMC Trucks Terrain varies by sub-model, so trim identification matters before any tire choice is made. Several trims share a size, while others move to a different wheel diameter and tire profile, making wheel confirmation just as important as the badge on the vehicle.

2024 GMC Trucks Terrain AT4
The 2024 GMC Trucks Terrain AT4 uses the 225/65R17 radial size. That makes the buying decision less about sorting through multiple primary fitments and more about choosing a tire that suits how the vehicle is actually used, including whether a more aggressive all-terrain style is desired.
The 2024 GMC Trucks Terrain Denali uses the 235/50R19 radial size. Tire selection here begins with confirming the 19-inch wheel setup, then comparing replacement options that maintain the intended fitment and overall appearance of the Denali package.
The 2024 GMC Trucks Terrain SLE uses the 225/65R17 radial size. That keeps fitment straightforward as long as the vehicle still wears its correct 17-inch wheels, after which the main consideration becomes selecting a tire built for the Terrain's typical road use and driving conditions.
The 2024 GMC Trucks Terrain SLE Elevation Edition uses the 235/50R19 radial size. Choosing tires for this version starts with the 19-inch wheel diameter, then moves to matching the vehicle's intended road use and keeping the replacement size consistent with the trim's fitment.
The 2024 GMC Trucks Terrain SLT can use either 225/60R18 or 235/50R19 radial tires, making wheel diameter the first thing to verify. Once the vehicle's actual wheel package is confirmed, the tire decision becomes much more straightforward because each size is tied to a specific rim diameter.
The 2024 GMC Trucks Terrain SLT Elevation Edition uses the 235/50R19 radial size. Tire selection should stay centered on the 19-inch setup and on choosing a replacement that matches the vehicle's existing wheel diameter, clearance, and normal driving 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.

The most useful tire questions for the 2024 GMC Trucks Terrain usually center on trim-specific size differences, wheel diameter, and how to choose the right radial tire for everyday driving or a more rugged 17-inch setup.
Tire Size & Fitment
What tire size fits a 2024 GMC Trucks Terrain?
The 2024 GMC Trucks Terrain uses three different tire sizes: 225/65R17, 225/60R18, and 235/50R19. The correct size depends on the exact sub-model and wheel package, so there is not one universal fitment across the entire Terrain lineup.
Trim and wheel diameter should be confirmed before choosing a replacement tire. AT4 and SLE use 225/65R17, Denali, SLE Elevation Edition, and SLT Elevation Edition use 235/50R19, and SLT can use either 225/60R18 or 235/50R19 depending on the wheel setup actually on the vehicle.
What size rim does a 2024 GMC Trucks Terrain use?
A 2024 GMC Trucks Terrain can use 17-inch, 18-inch, or 19-inch rims, depending on sub-model. The tire sizes match those wheel diameters directly: 225/65R17 fits a 17-inch rim, 225/60R18 fits an 18-inch rim, and 235/50R19 fits a 19-inch rim.
Wheel diameter is the first fitment checkpoint because the wrong rim size rules out the tire immediately. It also helps to verify the actual wheels on the vehicle, especially if it was purchased used or has seen aftermarket wheel changes, since an SLT may be fitted with either 18-inch or 19-inch wheels.
Why does the 2024 GMC Trucks Terrain have more than one tire size?
The 2024 GMC Trucks Terrain has more than one tire size because different sub-models use different wheel packages. Across the lineup, GMC paired the Terrain with 17-inch, 18-inch, or 19-inch wheels, which is why the tire sizes change from one trim to another.
That means tire selection starts with the exact trim name and the wheel diameter currently on the vehicle, not just the model badge. An SLT is a good example, since it can use either 225/60R18 or 235/50R19, so checking the installed wheel size avoids ordering the wrong tire profile.
Choosing the Right Tire
What should I consider when choosing a 225/65R17 tire for a 2024 GMC Trucks Terrain?
Start with the correct application, since 225/65R17 belongs to specific 2024 GMC Trucks Terrain trims rather than the entire model range. After that, compare tire type, construction, rim-width compatibility, load capacity, and whether the Terrain is used mainly for commuting, weather exposure, or light off-pavement driving.
The available 225/65R17 product shown here is a BFGoodrich All Terrain T/A KO2 radial with an RBL sidewall, a 6.0- to 8.0-inch rim-width range, and a 2,150-pound maximum load capacity at 65 psi. That makes it important to confirm wheel width and intended use instead of choosing only by size marking.
What sidewall styles are available for 2024 GMC Trucks Terrain tires?
Among the currently shown Terrain tire options, the visible sidewall style is RBL in 225/65R17. RBL is a styling detail that gives the tire a more defined sidewall appearance and can matter to owners who want a more rugged visual presentation on AT4 or SLE trims.
Sidewall style should always come after correct size and wheel diameter in the decision process. Once fitment is confirmed, sidewall appearance can help narrow the final choice, especially on a compact SUV where wheel-and-tire style changes the overall look as much as the tread pattern does.
What brands offer tires for the 2024 GMC Trucks Terrain?
The currently shown product coverage for the 2024 GMC Trucks Terrain includes BFGoodrich in 225/65R17. That option is part of the All Terrain T/A KO2 series and is aimed at buyers who want a radial tire with a more aggressive all-terrain character than a basic road-oriented replacement.
Brand should be compared alongside the actual tire series, sidewall treatment, wheel-width compatibility, and how the Terrain is driven. A tire can be the correct size and still be better suited to one use pattern than another, so daily pavement driving and occasional rough-surface use should be weighed before selecting.
Restoration & Appearance
Which tire should I choose for a period-style 2024 GMC Trucks Terrain?
A period-style approach is usually not the main concern on a 2024 GMC Trucks Terrain, so the best starting point is the correct factory-era size for the exact trim and wheel package. That means choosing among 225/65R17, 225/60R18, or 235/50R19 only after confirming the installed wheel diameter.
Appearance still matters, especially on trims with a more rugged or more upscale presentation. A 225/65R17 all-terrain radial can give an AT4 or similarly equipped Terrain a tougher visual stance, while other trims may call for a cleaner road-oriented replacement that preserves the intended wheel-and-tire balance.
Does correct tire fitment matter for a 2024 GMC Trucks Terrain restoration or refresh?
Correct tire fitment matters on a 2024 GMC Trucks Terrain because wheel diameter, tire profile, and trim-specific sizing all shape how the vehicle sits and drives. Even on a newer vehicle, using the wrong size can change the overall appearance and move the tire away from the intended proportions.
A clean refresh should begin with the exact sub-model and the wheels actually on the vehicle. Once the proper size is confirmed, appearance choices such as tread style or sidewall presentation can be considered without losing sight of the basic fitment relationship between the Terrain, its rims, and its fender clearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 GMC Trucks Terrain?
Yes, modifications can affect tire fitment on a 2024 GMC Trucks Terrain. Aftermarket wheels, suspension changes, ride-height adjustments, or even a different trim's wheel takeoff set can change the relationship between tire size, rim width, and available clearance at the fenders and steering components.
That is why replacement tires should be matched to the actual wheel diameter and wheel width currently on the vehicle, not only the original trim designation. A changed setup can also affect whether the tire clears through full steering travel, so checking the complete wheel-and-tire package is a smart step before purchase.
What should I inspect before driving a 2024 GMC Trucks Terrain on new tires?
Before driving on new tires, inspect tire pressure, bead seating, wheel condition, valve stems, and lug-nut torque. It also helps to confirm that all four tires match the intended size for the Terrain's trim and that there is no rubbing at the fenders, liners, or suspension during full steering lock.
A short initial road check can reveal vibration, pull, or unexpected clearance issues before the vehicle is put into regular use. Tire age is not usually the first concern on a 2024 model, but cuts, punctures, impact damage, and air loss still deserve attention whenever a new set is installed.
What should I check before a longer drive in a 2024 GMC Trucks Terrain?
Before a longer drive, check air pressure, tread condition, sidewall condition, and the spare or inflator equipment carried with the 2024 GMC Trucks Terrain. A quick look for nails, cuts, bulges, or uneven wear can catch a problem early, especially if the vehicle has recently had tires rotated or replaced.
It is also wise to confirm that the Terrain is running the correct size for its trim and wheel package, since long highway miles can expose vibration or clearance issues more clearly than short local trips. Any recent wheel swap or suspension work makes that verification even more important before extended driving.
