The 2017 GMC Trucks Sierra 1500 sits in the full-size pickup market as a truck that could range from straightforward work duty to upscale daily use, depending on trim and wheel package. That matters when choosing tires, because this Sierra 1500 uses several different radial sizes across Base, SLE, SLT, and Denali configurations. The fitment question starts with identifying the exact sub-model and wheel diameter, since 17-inch, 18-inch, 20-inch, and 22-inch setups all appear here. Available product coverage in this fitment centers on 265/70R17, with BFGoodrich All-Terrain T/A KO2 options in raised white letter form. Before choosing, confirm the truck's actual wheel setup, especially if wheels or suspension have been changed.
Which Tire Size Is Right for The 2017 GMC Trucks Sierra 1500
The 2017 GMC Trucks Sierra 1500 uses five primary tire sizes, and the correct one depends on sub-model and wheel diameter. All of them are metric radial sizes, but they span 17-inch, 18-inch, 20-inch, and 22-inch rims, so confirming the truck's exact trim and actual wheel setup is the first step before comparing tire choices.
255/70R17 is a metric radial size in which 255 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. On the 2017 GMC Trucks Sierra 1500, this size belongs to 17-inch wheel applications rather than the larger wheel packages used on other sub-models. It suits buyers who need to stay with the original 17-inch fitment path for the trims that use it. The practical step is confirming that the truck still carries the correct 17-inch wheels before selecting a tire in this size.
265/70R17 is a metric radial size with a 265-millimeter nominal section width, a 70-series profile, radial construction, and a 17-inch rim diameter. It is one of the 17-inch Sierra 1500 fitments and also the size with visible product choice here, including BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls. Those products share the same tire series but differ in load capacity, pressure rating, weight, and rim-width specification details. This size is worth close attention if the truck is equipped with 17-inch wheels and the goal is to compare available all-terrain product characteristics within the correct fitment.
275/55R20 follows the same metric radial format: 275 millimeters of nominal section width, a 55-series profile, radial construction, and a 20-inch rim. On the 2017 GMC Trucks Sierra 1500, this size belongs to trims and wheel packages that use 20-inch wheels rather than the smaller 17-inch and 18-inch setups. Its lower profile relative to the 17-inch and 18-inch sizes makes wheel confirmation especially important before purchase. Buyers looking at this size should verify that the truck still has the correct 20-inch wheels and has not been changed to a different factory or aftermarket setup.
285/45R22 is a metric radial size with a 285-millimeter nominal section width, a 45-series profile, and a 22-inch rim diameter. Within the 2017 GMC Trucks Sierra 1500 range, it belongs to the largest wheel applications and is tied to trims that use a more aggressive wheel package than the 17-inch, 18-inch, or 20-inch fitments. That makes wheel diameter and clearance confirmation especially important if the truck has seen any wheel, suspension, or ride-height changes. This is the size to evaluate only when the truck is truly set up around a 22-inch wheel package.
265/65R18 is a metric radial size where 265 is the nominal width in millimeters, 65 is the aspect ratio, R marks radial construction, and 18 is the wheel diameter in inches. For the 2017 GMC Trucks Sierra 1500, it fills the middle ground between the 17-inch and 20-inch or 22-inch fitments used on other sub-models. That makes it a trim-specific size rather than a universal Sierra 1500 tire. Buyers should treat it as an 18-inch application first and confirm the truck's actual wheels before comparing tread style, tire category, or overall road-use goals.
Tire fitment on the 2017 GMC Trucks Sierra 1500 varies by sub-model, and several trims can use more than one size depending on wheel package. Checking the exact trim matters here because the Sierra 1500 spans four wheel diameters and five primary radial sizes.

2017 GMC Trucks Sierra 1500 Base
The 2017 GMC Trucks Sierra 1500 Base uses 17-inch radial tire fitments, with either 255/70R17 or 265/70R17 depending on configuration. That keeps the decision focused on confirming which 17-inch setup is on the truck and then comparing tire type, load specification, and intended use within that size.
The 2017 GMC Trucks Sierra 1500 Denali uses larger wheel-package fitments, with 275/55R20 or 285/45R22 radial tires. Tire selection starts with confirming whether the truck is on its 20-inch or 22-inch wheels, since the correct size follows the wheel diameter rather than the Denali name alone.
The 2017 GMC Trucks Sierra 1500 SLE has the widest fitment spread, covering 255/70R17, 265/70R17, 265/65R18, and 275/55R20. That makes wheel diameter the key checkpoint, especially on trucks that may have changed wheels over time or were equipped with different packages from new.
The 2017 GMC Trucks Sierra 1500 SLT uses 265/65R18, 275/55R20, or 285/45R22 radial tire fitments depending on wheel package. The practical step is to verify whether the truck is on 18-inch, 20-inch, or 22-inch wheels before narrowing the choice to tread style and product specifications.
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:

Tire Size & Fitment
What tire size fits a 2017 GMC Trucks Sierra 1500?
The 2017 GMC Trucks Sierra 1500 uses five primary tire sizes: 255/70R17, 265/70R17, 265/65R18, 275/55R20, and 285/45R22. All are radial sizes, but they do not apply across the entire model line. The correct size depends on the truck's exact sub-model and wheel package.
The most important next step is to confirm the wheel diameter actually on the truck, since Sierra 1500 fitments here span 17-inch, 18-inch, 20-inch, and 22-inch rims. Trim level helps narrow the range, but the physical wheel setup matters most if the truck has been changed from its original configuration.
What size rim does a 2017 GMC Trucks Sierra 1500 use?
A 2017 GMC Trucks Sierra 1500 can use 17-inch, 18-inch, 20-inch, or 22-inch rims, depending on sub-model and wheel package. The tire sizes match those rim diameters directly: 255/70R17 and 265/70R17 use 17-inch rims, 265/65R18 uses an 18-inch rim, 275/55R20 uses a 20-inch rim, and 285/45R22 uses a 22-inch rim.
That range means there is no single rim size for every Sierra 1500. A buyer should check the truck itself rather than rely only on model name, especially if it has aftermarket wheels or a trim package with larger factory wheels. Tire selection should begin with wheel diameter, then move to the exact size.
Do all 2017 GMC Trucks Sierra 1500 sub-models use the same tire size?
No, the 2017 GMC Trucks Sierra 1500 sub-models do not all use the same tire size. Base uses 255/70R17 or 265/70R17, Denali uses 275/55R20 or 285/45R22, SLE can use four sizes from 17-inch through 20-inch fitments, and SLT can use 18-inch, 20-inch, or 22-inch sizes.
That variation makes sub-model and wheel package identification a necessary part of the buying process. Even within one trim, more than one size may apply, so checking the sidewall of the current tire and confirming the actual wheel diameter are both smart steps before comparing brands, tread styles, or load specifications.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 GMC Trucks Sierra 1500?
Start with the correct tire size for the truck's exact trim and wheel diameter. A 2017 GMC Trucks Sierra 1500 can use 17-inch, 18-inch, 20-inch, or 22-inch fitments, so size comes before brand or tread style. Construction is straightforward here because every primary fitment is radial.
Once the size is confirmed, compare the tire's intended use, sidewall style, load specification, and wheel compatibility. A truck used for highway driving may call for a different type of tire than one used for mixed on-road and off-road service. On 265/70R17, load capacity and rim-width range are also worth checking closely.
What sidewall styles are available for 2017 GMC Trucks Sierra 1500 tires?
The visible sidewall style in the available product selection for this fitment is RWL, or raised white letter. That appears on the 265/70R17 BFGoodrich All-Terrain T/A KO2 options, giving the tire a more traditional truck-performance look than a plain black sidewall.
Sidewall style affects appearance more than fitment, so it should be chosen after the correct tire size is confirmed. Buyers trying to keep a clean factory-inspired look may prefer one presentation, while others may want the more assertive raised white letter style. The key is not to let sidewall preference override proper size and wheel compatibility.
What brands offer tires for the 2017 GMC Trucks Sierra 1500?
The available product selection shown for this fitment includes BFGoodrich. Within the current coverage, BFGoodrich appears in the 265/70R17 size with All-Terrain T/A KO2 products that differ by load capacity, inflation specification, and weight while remaining in the same tire family.
Brand choice should still be filtered through the truck's exact size requirement first. A Sierra 1500 using 18-inch, 20-inch, or 22-inch fitments needs the correct size before any meaningful product comparison can happen. On 265/70R17, the useful comparison is not just brand name, but how each version matches the truck's intended duty.
Restoration & Appearance
Which tire should I choose for a period-style 2017 GMC Trucks Sierra 1500?
A period-style approach for a 2017 GMC Trucks Sierra 1500 usually starts with keeping the correct original fitment size for the truck's trim and wheel package. Because this is a modern full-size pickup, the most authentic-looking result generally comes from matching the proper 17-inch, 18-inch, 20-inch, or 22-inch tire size first.
Appearance choices should stay secondary to fitment. If the truck is on 265/70R17, the available raised white letter BFGoodrich all-terrain option gives a strong truck-era visual character, but style alone should not drive the decision. Wheel changes, oversized upgrades, and altered ride height can shift the look away from a stock presentation quickly.
How does tire construction affect the appearance of a restored 2017 GMC Trucks Sierra 1500?
Tire construction is simple on the 2017 GMC Trucks Sierra 1500 because the primary fitments here are all radial. That means appearance differences come less from bias-ply versus radial choice and more from size, sidewall presentation, tread character, and whether the truck remains on its correct wheel diameter.
A restored or carefully kept Sierra 1500 usually looks most cohesive when the tire size matches the intended trim-level stance. Raised white letter sidewalls can add a more assertive truck look, while the wrong wheel diameter or profile can change the whole visual balance. Keeping the proper size is the foundation of getting the appearance right.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 GMC Trucks Sierra 1500?
Yes, modifications can affect tire fitment on a 2017 GMC Trucks Sierra 1500. Wheel changes, suspension lifts, lowering kits, altered offsets, and even brake upgrades can change the space available for the tire. That matters because this truck already spans several factory wheel diameters and tire sizes.
A modified truck should be checked for actual wheel diameter, wheel width, and clearance at the fender and steering range before replacement tires are chosen. Even when the sidewall shows a familiar size, the surrounding setup may be different from stock. Matching the replacement tire to the truck as it sits now is the practical goal.
What should I inspect before driving a 2017 GMC Trucks Sierra 1500 on new tires?
Before driving a 2017 GMC Trucks Sierra 1500 on new tires, inspect the wheels for damage, confirm the lug hardware is correct, and make sure the tire size matches the truck's actual wheel diameter. Tire pressure should also be set correctly, and the tires should be checked for any shipping or mounting damage before road use.
A short initial drive is a good time to watch for rubbing, vibration, or steering interference that may point to wheel or suspension issues. It also helps to recheck pressure after installation and look over the sidewalls again after the first miles. Those basic steps matter even more on trucks with non-stock wheels.
How often should tires on a 2017 GMC Trucks Sierra 1500 be inspected?
Tires on a 2017 GMC Trucks Sierra 1500 should be inspected regularly, not just when tread looks worn. A quick visual check for cuts, punctures, uneven wear, cracking, bulges, and pressure loss is worthwhile before longer drives, after hauling or towing, and anytime the truck has been parked for an extended period.
Routine inspection matters because tire condition can reveal alignment, suspension, or inflation problems before they become larger issues. A Sierra 1500 with larger wheels or all-terrain tires may also mask wear patterns until they are advanced. Checking both outer and inner sidewalls, and verifying pressure with a gauge, helps keep the truck road-ready.
