The 2024 GMC Trucks Sierra 1500 sits in the modern full-size pickup market with a wide spread of trim personalities, from work-oriented models to upscale highway cruisers and off-road-ready versions. That variety shows up clearly in tire fitment, because this Sierra 1500 uses several different metric radial sizes depending on the exact sub-model and wheel package. The main decision is not simply picking a tire for a Sierra, but matching the correct size to the truck’s rim diameter and trim-specific setup. Available products here focus on truck-ready radial choices, including BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls. Before choosing, confirm the exact sub-model and wheel size on the truck itself.
Which Tire Size Is Right for The 2024 GMC Trucks Sierra 1500
The 2024 GMC Trucks Sierra 1500 uses seven primary tire sizes, and they vary by sub-model and wheel package across 17-inch, 18-inch, 20-inch, and 22-inch rims. The first step is confirming the exact sub-model and actual wheel diameter on the truck, because the right choice depends on both trim-level fitment and rim size rather than a single universal Sierra 1500 tire.
265/60R20 is a metric radial size with a 265 millimeter nominal section width, a 60-series aspect ratio, and fitment for a 20-inch wheel. On the 2024 GMC Trucks Sierra 1500, it serves as one of the trim-dependent modern radial fitments rather than a universal size across the lineup. Its sizing places it in the group of larger-diameter wheel packages that suit trucks equipped with 20-inch rims. This size should be evaluated by confirming the exact trim and wheel setup on the truck, especially if it has been changed from its original wheel package.
Fit(s): AT4, Denali, Elevation, Pro Graphite Edition, SLE, and SLT
Construction: Radial|Rim: 20 in
275/60R20 is a metric radial size that uses a 275 millimeter nominal section width, a 60-series profile, and a 20-inch rim diameter. It appears across several 2024 GMC Trucks Sierra 1500 sub-models, making it one of the more widely used fitments in the range, but it still is not shared by every configuration. This size belongs to the truck’s modern radial fitment pattern and should be matched to the correct wheel package rather than chosen by appearance alone. Buyers comparing this size should verify the truck’s trim, wheel diameter, and any wheel or suspension changes before selection.
Fit(s): AT4, AT4X, AT4X AEV Edition, and Pro 4x4 w/X31 Off-Road Pkg.
Construction: Radial|Rim: 18 in
275/65R18 is a metric radial size with a 275 millimeter nominal section width, a 65-series aspect ratio, and an 18-inch wheel diameter. On the 2024 GMC Trucks Sierra 1500, it is used on specific off-road-oriented or package-specific sub-models, so it should not be assumed to apply to every Sierra 1500 with an 18-inch wheel. Available product coverage in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls and a 7.5 to 9.5 inch rim-width range. This size makes the most sense when the truck’s trim and wheel package already call for it.
275/50R22 is a metric radial size that combines a 275 millimeter nominal section width with a lower 50-series profile for a 22-inch wheel. Within the 2024 GMC Trucks Sierra 1500 range, it belongs to specific upper-trim configurations and is tied closely to that larger wheel diameter. Its role is distinct from the 17-, 18-, and 20-inch fitments used elsewhere in the lineup, so rim confirmation matters before anything else. This size should be chosen only after verifying that the truck is equipped for a 22-inch package and has the wheel and clearance setup to match.
255/70R17 is a metric radial size with a 255 millimeter nominal section width, a 70-series aspect ratio, and fitment for a 17-inch wheel. On the 2024 GMC Trucks Sierra 1500, it is used on selected lower-trim configurations rather than across the full model range. That makes it a trim- and wheel-specific fitment, not a substitute for the wider 17-inch, 18-inch, 20-inch, or 22-inch options used on other Sierra 1500 versions. Buyers should confirm both the sub-model and the actual wheel diameter before treating this size as the correct choice.
265/70R17 is a metric radial size using a 265 millimeter nominal section width, a 70-series profile, and a 17-inch wheel diameter. On the 2024 GMC Trucks Sierra 1500, it appears on certain trims that use 17-inch wheels and should be matched carefully to that exact setup. Available product choices in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls, offered in different load-capacity versions on 7.0 to 9.0 inch rim widths. This size is worth evaluating when the truck’s trim and wheel package call for a 17-inch off-road-capable radial option.
265/65R18 is a metric radial size with a 265 millimeter nominal section width, a 65-series aspect ratio, and an 18-inch rim diameter. It is one of the 18-inch fitments used on selected 2024 GMC Trucks Sierra 1500 sub-models, but it is separate from the wider 275/65R18 size found on other configurations. That distinction matters because two 18-inch sizes can exist within the same model range without serving the same trims or packages. This size should be chosen only after confirming the sub-model and wheel package rather than assuming any 18-inch Sierra 1500 uses it.
Tire fitment for the 2024 GMC Trucks Sierra 1500 varies significantly by sub-model, and several trims use more than one size depending on wheel package. Checking the exact trim name matters here, because Sierra 1500 fitment spans four rim diameters and multiple metric radial sizes.

2024 GMC Trucks Sierra 1500 AT4
The 2024 GMC Trucks Sierra 1500 AT4 can use more than one radial tire size, so the wheel package on the truck needs to be confirmed before choosing tires. That makes rim diameter and the truck’s current setup more important than ordering by trim name alone.
The 2024 GMC Trucks Sierra 1500 AT4X uses a single primary radial tire size, which makes fitment more straightforward than on trims with multiple wheel packages. Tire selection then becomes a matter of matching that size correctly and checking wheel compatibility, load capacity, and intended use.
The 2024 GMC Trucks Sierra 1500 AT4X AEV Edition follows a single primary radial tire-size fitment within this coverage. That keeps the focus on choosing the right tire within the correct size and confirming the truck’s existing wheel setup before replacement.
The 2024 GMC Trucks Sierra 1500 Denali uses more than one radial tire size, and those sizes also involve different wheel diameters. Tire selection starts with verifying whether the truck has the 20-inch or 22-inch setup, since that determines the correct fitment path.
The 2024 GMC Trucks Sierra 1500 Denali Ultimate uses one primary radial size tied to its larger wheel package. That simplifies sizing, but wheel confirmation still matters because a 22-inch fitment should not be confused with other Sierra 1500 trim setups.
The 2024 GMC Trucks Sierra 1500 Elevation uses a single primary radial tire size in this coverage. The main selection work is then comparing available tires within that size and making sure the truck still carries the correct wheel package.
The 2024 GMC Trucks Sierra 1500 Pro can use two different 17-inch radial tire sizes, so the exact wheel and trim configuration should be checked before replacing tires. That distinction is especially important on work-oriented trucks that may already have seen wheel or tire changes in service.
2024 GMC Trucks Sierra 1500 Pro 4x4 w/X31 Off-Road Pkg.
The 2024 GMC Trucks Sierra 1500 Pro 4x4 w/X31 Off-Road Pkg. uses a single primary radial fitment in this coverage. Tire selection should stay focused on that size and on confirming wheel width, load needs, and current truck configuration before replacement.
The 2024 GMC Trucks Sierra 1500 Pro Graphite Edition uses one primary radial size within this fitment range. With sizing narrowed down, the practical decision becomes verifying the 20-inch wheel setup and selecting the tire that suits the truck’s road use and appearance goals.
The 2024 GMC Trucks Sierra 1500 SLE has the widest spread of tire sizes in this group, with multiple radial fitments across 17-inch, 18-inch, and 20-inch wheels. Tire choice depends on confirming the exact wheel package first, since trim name alone is not enough to identify the right size.
The 2024 GMC Trucks Sierra 1500 SLT uses several radial tire sizes, including fitments tied to different wheel diameters. That makes wheel confirmation the key step before comparing tires, especially where 18-inch, 20-inch, and 22-inch setups can all appear within the same trim family.
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 2024 GMC Trucks Sierra 1500?
The 2024 GMC Trucks Sierra 1500 does not use one universal tire size across the entire model line. Fitments include 255/70R17, 265/70R17, 265/65R18, 275/65R18, 265/60R20, 275/60R20, and 275/50R22, all in radial construction.
The right choice depends on the exact sub-model and wheel package on the truck. A Pro, SLE, Denali, or AT4 can use different sizes, so the safest starting point is to confirm the trim and measure the wheel diameter before comparing tires.
What size rim does a 2024 GMC Trucks Sierra 1500 use?
A 2024 GMC Trucks Sierra 1500 can use 17-inch, 18-inch, 20-inch, or 22-inch rims depending on the sub-model and tire size. Those rim diameters correspond to the primary fitments used across the Sierra 1500 lineup rather than a single standard wheel for every truck.
Wheel diameter should be confirmed before anything else because several trims can appear with different packages. Even within the same model family, a truck on 17-inch wheels requires a very different tire choice than one equipped with 20-inch or 22-inch rims.
Do all 2024 GMC Trucks Sierra 1500 sub-models use the same tire size?
No, 2024 GMC Trucks Sierra 1500 sub-models do not all use the same tire size. The fitment spread includes seven different radial sizes, and several trims such as AT4, Denali, SLE, and SLT can use more than one size depending on configuration.
That variation means trim name alone may not be enough to identify the correct tire. Checking the exact sub-model, current wheel diameter, and any prior wheel or suspension changes will narrow the fitment correctly and prevent mixing a size meant for another Sierra 1500 setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 GMC Trucks Sierra 1500?
Start with the correct primary size for the exact 2024 GMC Trucks Sierra 1500 sub-model and wheel package. This truck uses several metric radial sizes, so the first decision is fitment, followed by the tire’s intended use, load specification, rim-width compatibility, and overall product character.
Once the size is confirmed, compare the details that matter for how the truck is used. A work truck, an off-road-oriented trim, and a highway-focused luxury trim may all need different priorities even within the same model line, so avoid choosing by appearance or brand name alone.
What sidewall styles are available for 2024 GMC Trucks Sierra 1500 tires?
The currently covered product options for the 2024 GMC Trucks Sierra 1500 use RWL sidewalls, which means raised white letter styling. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options available here in 275/65R18 and 265/70R17.
Sidewall style affects the truck’s visual presentation as much as the tire series itself. Raised white letters tend to suit a more aggressive truck look, but the first priority is still matching the correct size, load specification, and wheel-width range for the Sierra 1500’s actual setup.
What brands offer tires for the 2024 GMC Trucks Sierra 1500?
The current product selection for the covered 2024 GMC Trucks Sierra 1500 sizes includes BFGoodrich. The available BFGoodrich options are part of the All-Terrain T/A KO2 line in 275/65R18 and 265/70R17, both in radial construction with raised white letter sidewalls.
Brand comparison should come after fitment is settled. Once the correct size is confirmed, focus on the exact tire specification, including load rating, rim-width compatibility, and how the tire will be used, since one size can also carry more than one load-capacity version.
Restoration & Appearance
Which tire should I choose for a period-style 2024 GMC Trucks Sierra 1500?
A period-style approach matters less on a 2024 GMC Trucks Sierra 1500 than it would on a collector-era vehicle, so the right starting point is the correct modern metric radial size for the exact trim and wheel package. Preserving the truck’s intended stance begins with accurate fitment, not with a vintage-style construction choice.
Appearance still plays a role, especially on trucks with a more aggressive or off-road presentation. Raised white letter sidewalls can reinforce that look, but they should be chosen only after confirming the proper tire size, wheel diameter, and load specification for the Sierra 1500’s actual configuration.
How does tire construction affect the appearance of a restored 2024 GMC Trucks Sierra 1500?
The 2024 GMC Trucks Sierra 1500 uses radial tire fitments throughout this range, so construction choice is not a bias-ply-versus-radial restoration issue here. Visual character is shaped more by wheel diameter, tire profile, sidewall styling, and the specific truck-oriented tread series than by a historical construction decision.
That means a clean, proper appearance usually comes from staying with the correct radial size and matching the truck’s trim identity. A 22-inch Denali setup presents differently than a 17-inch or 18-inch off-road-oriented Sierra, so fitment accuracy is the foundation of the overall look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 GMC Trucks Sierra 1500?
Yes, modifications can affect tire fitment on a 2024 GMC Trucks Sierra 1500 even when the truck started with a correct factory-size radial. Changes such as aftermarket wheels, different wheel widths, suspension lifts or lowering, and body or fender alterations can all change clearance and tire-selection limits.
A Sierra 1500 with changes should be checked by actual wheel diameter, wheel width, and available clearance rather than by trim alone. Steering travel, suspension movement, and the exact tire specification all matter once the truck no longer matches its original wheel and suspension setup.
What should I inspect before driving a 2024 GMC Trucks Sierra 1500 on new tires?
Before road use, inspect inflation pressure, lug-nut torque, tread and sidewall condition, and confirm that the new tires match the truck’s correct size and wheel diameter. It also helps to look for any rubbing at the inner fender, suspension, or steering components with the wheels turned fully.
A short test drive should include listening for contact and feeling for any pull, vibration, or unusual response. After the first miles, recheck pressure and inspect the tires again, especially on a Sierra 1500 that has changed wheel packages or carries a higher-load truck tire specification.
What should I check before a longer drive in a 2024 GMC Trucks Sierra 1500?
Before a longer drive, make sure the 2024 GMC Trucks Sierra 1500 has the correct tire size for its sub-model, proper inflation, and no visible cracking, cuts, bulges, or uneven wear. Tread condition, air retention, and general wheel condition deserve attention before putting the truck into extended highway use.
Longer trips are also a good time to confirm that the tire’s load specification matches how the truck will be used. On a Sierra 1500 with off-road tires, aftermarket wheels, or a changed suspension stance, a final clearance check can prevent surprises once the truck is fully loaded and underway.
