The 2022 GMC Trucks Sierra 2500 HD sits firmly in the modern heavy-duty pickup world, where towing, payload, off-pavement use, and long-distance road manners all shape tire choice. Buyers often know the truck by trim, but tire fitment on this Sierra 2500 HD also depends on the exact sub-model and wheel package. This truck uses radial tire sizes ranging from 245/75R17 up to 275/65R20, with 17-inch, 18-inch, and 20-inch rim diameters in play. Available choices center on BFGoodrich All-Terrain T/A KO2 products with raised white letter or raised black letter sidewall treatments. The key is matching the truck's exact size and wheel diameter before comparing load capacity, rim-width range, and appearance.
Which Tire Size Is Right for The 2022 GMC Trucks Sierra 2500 HD
Four primary tire sizes apply to the 2022 GMC Trucks Sierra 2500 HD, and they vary by sub-model and wheel package. The first step is confirming the exact trim and rim diameter, since this truck may use 17-inch, 18-inch, or 20-inch wheels. Once that is settled, the decision shifts to the right radial size, load specification, rim-width compatibility, and sidewall presentation within the available options.
275/65R20 is a metric radial size in which 275 is the section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2022 GMC Trucks Sierra 2500 HD, this size is part of the larger-wheel fitment used on certain sub-models. Available product choice centers on the BFGoodrich All-Terrain T/A KO2 with an RBL sidewall treatment. This size makes sense when the truck is already equipped with 20-inch wheels and the goal is to stay with the established fitment rather than stepping to a different wheel diameter.
275/70R18 uses the same 275-millimeter nominal section width as the 20-inch size, but it is built for an 18-inch rim and uses a 70-series profile. It is a radial fitment for the 2022 GMC Trucks Sierra 2500 HD and appears across more than one sub-model, making exact trim and wheel confirmation especially important. The available BFGoodrich All-Terrain T/A KO2 version carries an RWL sidewall style. This size is a useful choice when the truck already wears 18-inch wheels and the buyer wants to compare tire load specification, rim-width range, and appearance within that setup.
245/75R17 is a metric radial size with a 245-millimeter nominal section width, a 75-series aspect ratio, and a 17-inch rim diameter. On the 2022 GMC Trucks Sierra 2500 HD, it serves as one of the 17-inch wheel fitments used on selected sub-models rather than across the full lineup. The available BFGoodrich All-Terrain T/A KO2 comes with an RWL sidewall treatment and a narrower approved rim-width range than the larger 17-inch alternative. This size is worth choosing when the truck's wheel setup calls for it and a more exact match to the existing 17-inch package is the priority.
265/70R17 is a metric radial size where 265 gives the nominal section width in millimeters, 70 is the aspect ratio, and 17 is the rim diameter in inches. For the 2022 GMC Trucks Sierra 2500 HD, it is another 17-inch fitment used on selected sub-models, so it should not be confused with the narrower 245/75R17 option. BFGoodrich All-Terrain T/A KO2 choices in this size are available with two different load specifications, both using an RWL sidewall. This size deserves closer comparison when the truck already has 17-inch wheels and the buyer needs to sort out the proper load range within the same basic tire size.
Tire fitment on the 2022 GMC Trucks Sierra 2500 HD varies by sub-model, and some trims use more than one wheel and tire package. Checking the exact trim first helps narrow down the correct rim diameter and keeps the tire search focused on the sizes that belong on that version of the truck.

2022 GMC Trucks Sierra 2500 HD AT4
The 2022 GMC Trucks Sierra 2500 HD AT4 uses either a 275/65R20 or 275/70R18 radial tire, so wheel diameter confirmation is the first step. Once the truck's current wheel package is verified, selection comes down to choosing the correct size and comparing the available all-terrain product details within that fitment.
The 2022 GMC Trucks Sierra 2500 HD Denali uses the 275/65R20 radial size, which makes fitment more straightforward than on trims with multiple wheel packages. Tire choice then centers on staying with the 20-inch fitment and reviewing sidewall style, rim-width compatibility, and load specification in that size.
The 2022 GMC Trucks Sierra 2500 HD Pro may use 245/75R17, 265/70R17, or 275/70R18 radial tires depending on the truck's wheel setup. That makes wheel diameter especially important to confirm before comparing tires, since a 17-inch or 18-inch fitment changes the correct size path immediately.
The 2022 GMC Trucks Sierra 2500 HD SLE has the widest fitment spread here, with 17-inch, 18-inch, and 20-inch radial tire options appearing across different configurations. The practical first step is checking the truck's current wheel diameter, then choosing the proper size before comparing load rating and sidewall presentation.
The 2022 GMC Trucks Sierra 2500 HD SLT uses either 275/65R20 or 275/70R18 radial tires, so the correct choice depends on which wheel package is on the truck. After that, the focus shifts to matching the established fitment and reviewing the available all-terrain tire specifications for that size.
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 2022 GMC Trucks Sierra 2500 HD?
The 2022 GMC Trucks Sierra 2500 HD uses four primary radial tire sizes: 275/65R20, 275/70R18, 245/75R17, and 265/70R17. The correct one depends on the truck's exact sub-model and wheel package, since this Sierra 2500 HD can be equipped with 17-inch, 18-inch, or 20-inch rims.
The safest starting point is the size already on the truck and the actual wheel diameter in use. A Pro, SLE, AT4, SLT, or Denali may not share the same combination, and some trims use more than one size. Before selecting a tire, confirm the trim, wheel diameter, and whether the truck still has its original wheel setup.
What size rim does a 2022 GMC Trucks Sierra 2500 HD use?
A 2022 GMC Trucks Sierra 2500 HD may use 17-inch, 18-inch, or 20-inch rims depending on the sub-model and tire package. The matching tire sizes are 245/75R17 and 265/70R17 for 17-inch wheels, 275/70R18 for 18-inch wheels, and 275/65R20 for 20-inch wheels.
Rim diameter is the first fitment detail to verify because the tire size must match it exactly. A 17-inch tire cannot be mounted on an 18-inch or 20-inch wheel, and the reverse is also true. Looking at the wheel itself and the current sidewall marking is often the quickest way to narrow the correct replacement path.
Why does the 2022 GMC Trucks Sierra 2500 HD have more than one tire size?
The 2022 GMC Trucks Sierra 2500 HD has more than one tire size because fitment changes across trims and wheel packages. Denali stays with 275/65R20, while trims such as Pro, SLE, AT4, and SLT can use different 17-inch, 18-inch, or 20-inch combinations depending on configuration.
That means tire selection starts with identifying the truck's exact setup rather than choosing by model name alone. Two Sierra 2500 HD trucks from the same year can require different sizes even when they look similar at a glance. Checking the current tire sidewall, wheel diameter, and trim helps avoid chasing the wrong size.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 GMC Trucks Sierra 2500 HD?
Start with the correct tire size for the truck's trim and wheel diameter, since the 2022 GMC Trucks Sierra 2500 HD uses several different radial sizes. After size, compare the tire's rim-width range, load capacity, construction, and the type of driving the truck actually sees, especially if it tows, hauls, or spends time off pavement.
The current product range centers on BFGoodrich All-Terrain T/A KO2 fitments, so the main comparison points are the exact size, sidewall treatment, and load specification within that size. It also helps to verify whether the truck still has its original wheels, because aftermarket changes can shift the fitment decision even when the trim name stays the same.
What sidewall styles are available for 2022 GMC Trucks Sierra 2500 HD tires?
Sidewall style on the available 2022 GMC Trucks Sierra 2500 HD tires includes RWL and RBL depending on size. The 275/70R18, 245/75R17, and 265/70R17 options use raised white letter styling, while the available 275/65R20 option uses a raised black letter presentation.
That difference matters mostly for appearance, since some owners want a more traditional all-terrain look while others prefer a darker sidewall on a larger wheel package. Sidewall style should be chosen after the correct size is confirmed, not before. The visual treatment may change from one size to another even within the same tire series.
What tire series are available for the 2022 GMC Trucks Sierra 2500 HD?
The available tire series for the 2022 GMC Trucks Sierra 2500 HD is BFGoodrich All-Terrain T/A KO2 across the supported sizes. That gives the page a fairly focused product mix, with variation coming more from size, sidewall style, rim-width range, weight, and load specification than from multiple series names.
For a buyer, that means the main decision is not between several unrelated tire families but between the correct Sierra 2500 HD fitment and the exact KO2 specification that matches the truck. Paying attention to the wheel diameter and load figure is especially important on a heavy-duty pickup, where the right size alone is not the whole story.
Restoration & Appearance
How does tire construction affect the appearance of a 2022 GMC Trucks Sierra 2500 HD?
On a 2022 GMC Trucks Sierra 2500 HD, tire construction is straightforward because the primary fitments here are all radial. Appearance is shaped more by the tire's size, wheel diameter, sidewall treatment, and overall all-terrain character than by a bias-ply versus radial decision, which is more common on older collector vehicles.
That puts the visual choice on details such as raised white letters versus raised black letters and the stance created by the truck's 17-inch, 18-inch, or 20-inch wheel package. Owners trying to preserve the truck's original look should verify the exact trim and wheel setup first, then choose a tire whose sidewall style supports that presentation.
Does correct tire fitment matter for a 2022 GMC Trucks Sierra 2500 HD restoration or appearance-focused build?
Correct tire fitment matters on a 2022 GMC Trucks Sierra 2500 HD because the truck's overall look changes noticeably with different wheel diameters and tire sizes. A 245/75R17, 275/70R18, or 275/65R20 setup gives the truck a different visual balance, even though each can be correct for certain sub-model and package combinations.
An appearance-focused build should start with the exact trim and wheel package the truck is meant to reflect. Once that is established, matching the proper size and sidewall treatment helps the truck look intentional rather than mixed between configurations. It is worth checking current wheels carefully, especially if the truck has changed hands or been modified.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 GMC Trucks Sierra 2500 HD?
Modifications can affect tire fitment on a 2022 GMC Trucks Sierra 2500 HD, especially if the truck has aftermarket wheels, suspension changes, leveling components, or body alterations. Even when the truck started with one of the correct factory size ranges, changes to wheel width, offset, or ride height can alter clearance and overall compatibility.
A truck that has been modified should be checked by actual wheel diameter and current tire size rather than by trim name alone. Look at steering clearance, fender space, and the wheel's width before replacing tires. That extra step is important on a heavy-duty pickup, where wheel and tire changes are common and can easily complicate fitment.
What should I inspect before driving a 2022 GMC Trucks Sierra 2500 HD on new tires?
Before driving a 2022 GMC Trucks Sierra 2500 HD on new tires, inspect tire pressure, lug torque, valve stems, and visible clearance at the front suspension, fenders, and inner wheel wells. It also helps to confirm that the installed tire size matches the truck's wheel diameter and that the load specification is appropriate for how the truck is used.
A short, careful test drive is a smart follow-up after installation. Listen for rubbing during turns, watch for vibration, and recheck pressure after the tires have settled in. On a truck that tows or carries weight, it is also worth confirming that all four tires match the intended setup before heading straight into a longer trip.
How often should tires on a 2022 GMC Trucks Sierra 2500 HD be inspected?
Tires on a 2022 GMC Trucks Sierra 2500 HD should be inspected regularly, with a quick visual check before routine road use and a closer inspection before towing, hauling, or taking a longer drive. Pay attention to tread wear, uneven wear patterns, cuts, bulges, embedded debris, cracking, and signs of air loss.
Heavy-duty pickups place real demands on their tires, so consistent inspection is more than a cosmetic habit. Checking pressure at the same time helps catch slow leaks and uneven loading early. Trucks that sit for stretches should still be looked over often, since age, weather exposure, and storage conditions can affect tire condition even when mileage stays low.
