2022 GMC Trucks Sierra 3500 HD Tires

The 2022 GMC Trucks Sierra 3500 HD uses three primary tire sizes: 275/65R20, 275/70R18, and 235/80R17. All three are radial sizes, but they do not apply across every version of the truck. Single-rear-wheel trims use the 20-inch or 18-inch fitments, while DRW sub-models use 235/80R17.

The correct choice depends on the truck's exact sub-model and actual wheel diameter. AT4, SLE, and SLT can appear with either 20-inch or 18-inch fitment, Denali uses 275/65R20, and DRW trims use 235/80R17. Checking the door-jamb tire label, current wheel size, and whether the truck is SRW or DRW is the safest way to confirm before replacement.

A 2022 GMC Trucks Sierra 3500 HD can use 20-inch, 18-inch, or 17-inch rims depending on configuration. The 275/65R20 tire fits a 20-inch rim, the 275/70R18 fits an 18-inch rim, and the 235/80R17 fits a 17-inch rim. Those rim diameters are tied directly to the tire size itself.

Wheel diameter is the first thing to confirm because these sizes are not interchangeable across different rim diameters. The available tires also carry different approved rim-width ranges, so diameter alone is not the whole story. A quick check of the wheel, the sidewall of the current tire, and the truck's SRW or DRW setup helps prevent ordering the right size for the wrong wheel.

The 2022 GMC Trucks Sierra 3500 HD has more than one tire size because different trims and wheel packages use different fitments, and DRW versions use a separate 17-inch tire size. AT4, SLE, and SLT can be fitted with either 275/65R20 or 275/70R18, while the DRW trucks use 235/80R17.

That means tire selection is configuration-driven rather than model-wide. A truck that has been optioned with larger wheels needs a different tire than the same trim on 18-inch wheels, and a dual-rear-wheel truck follows its own fitment path. Before replacing tires, confirm the exact trim, wheel diameter, and whether the rear axle setup is single or dual.

Start with the correct tire size for the truck's exact configuration: 275/65R20, 275/70R18, or 235/80R17. From there, compare radial construction details that matter on a heavy-duty pickup, including approved rim-width range, load capacity at the stated pressure, overall tire dimensions, and whether the truck is single-rear-wheel or DRW.

The available Sierra 3500 HD options here center on BFGoodrich All-Terrain T/A KO2 tires, so the decision is less about switching among many series and more about matching the correct size to the truck's wheels and use. Owners who tow, haul, or carry heavy loads should also confirm that the selected tire's load specification aligns with the vehicle's actual service demands.

Sidewall styles for the 2022 GMC Trucks Sierra 3500 HD include RBL and RWL, depending on the tire size. The 275/65R20 and 235/80R17 BFGoodrich All-Terrain T/A KO2 options use RBL sidewalls, while the 275/70R18 version uses an RWL sidewall treatment.

That matters mostly for appearance once the correct size has been confirmed. An RWL sidewall gives the truck a more visible, traditional off-road-style presentation, while RBL has a plainer black sidewall look. The sidewall choice should come after the fitment decision, not before it, since the tire size and wheel diameter still determine what belongs on the truck.

Rim-width range is an important comparison point on the 2022 GMC Trucks Sierra 3500 HD because each tire size has its own approved span. The 275/65R20 fits 7.5 to 9.5-inch rims, the 275/70R18 fits 7.0 to 9.0-inch rims, and the 235/80R17 fits 6.0 to 7.5-inch rims.

Those ranges help confirm that the tire matches the wheel, especially on trucks that may have changed wheels after delivery. A Sierra 3500 HD with aftermarket wheels, different offsets, or a work-truck replacement wheel set should be measured rather than assumed. Keeping the tire within its approved rim-width range supports proper tire shape, load carrying, and clearance.

Yes, correct tire fitment still matters even on a newer heavy-duty truck like the 2022 GMC Trucks Sierra 3500 HD. The right size keeps the truck visually consistent with its wheel package and configuration, whether that means 20-inch, 18-inch, or DRW 17-inch fitment. Using the wrong size can quickly make the truck look mismatched.

Appearance should be balanced with proper wheel and load compatibility. A stock-style presentation starts with matching the actual wheel diameter and SRW or DRW setup, then choosing the sidewall style that suits the truck's look. For owners pursuing a highly specific showroom-style result, original delivery documentation and vehicle-specific references are worth checking before finalizing details.

On the 2022 GMC Trucks Sierra 3500 HD, the primary fitments are radial tires, so construction changes are not the visual question they often are on older collector vehicles. The more noticeable appearance differences come from size, wheel diameter, and sidewall treatment, particularly the distinction between RBL and RWL versions of the available BFGoodrich all-terrain fitments.

A taller or wider-looking tire can change the truck's stance, but the tire still needs to match the wheel diameter and intended configuration. On this model, keeping the correct 20-inch, 18-inch, or 17-inch fitment family does more for a stock-style look than chasing a different construction type. Sidewall presentation is the finishing touch once fitment is settled.

Yes, modifications can affect tire fitment on a 2022 GMC Trucks Sierra 3500 HD even when the tire size is otherwise correct for the model. Aftermarket wheels, changes in wheel width or offset, suspension lifts or leveling kits, and body alterations can all influence how a 275/65R20, 275/70R18, or 235/80R17 tire sits on the truck.

A modified truck should be checked for steering clearance, fender clearance, and dual-wheel spacing where applicable. Wheel diameter must still match the tire, and rim width should stay within the approved range for that size. Any Sierra 3500 HD that has been altered from stock is best measured at the wheel and tire level before replacement instead of relying on trim alone.

Before driving a 2022 GMC Trucks Sierra 3500 HD on new tires, inspect inflation pressure, wheel-nut torque, visible sidewall condition, and tread seating across the full contact patch. It is also important to confirm that all tires match the intended size for the truck's configuration and that DRW trucks have the proper tire setup at the rear.

A short visual and road check is worthwhile after installation. Look for rubbing at full steering lock, uneven gap to suspension components, and any sign of contact under load. Heavy-duty trucks also deserve a close look at valve stems, wheel condition, and tire age if older spare tires remain in service alongside newer replacements.

Tires on a 2022 GMC Trucks Sierra 3500 HD should be maintained with regular pressure checks, routine inspections for cuts, bulges, cracking, and uneven wear, and periodic verification that the tires remain matched to the truck's wheel setup. Because this is a heavy-duty platform, inflation and condition matter even more when the truck is used for towing or hauling.

Maintenance should also include checking for slow air loss, monitoring tread wear patterns that could point to alignment issues, and inspecting wheels for damage. Trucks that sit for long periods still need attention, since age and storage conditions affect tire condition even when tread looks good. Any sign of rubbing or irregular wear deserves correction before continued road use.
