The 2016 GMC Trucks Sierra 2500 HD sits in the heavy-duty pickup world where towing, hauling, and long-wheelbase stability matter as much as day-to-day road manners. Buyers often know these trucks by trim and wheel package because appearance and equipment can change the tire fitment story quickly. This Sierra 2500 HD uses radial tire sizes that vary by sub-model and wheel diameter, including 245/75R17, 265/70R18, and 265/60R20. That makes the real decision less about vintage-style construction and more about confirming the truck's exact trim and wheel setup before comparing available tire choices. A restoration-style approach matters less here than accurate fitment, load capability, and intended truck use.
Which Tire Size Is Right for The 2016 GMC Trucks Sierra 2500 HD
Three primary tire sizes apply to the 2016 GMC Trucks Sierra 2500 HD, and they are tied to different sub-model and wheel combinations. The first step is confirming both the exact trim and the truck's actual rim diameter, since this model can use 17-inch, 18-inch, or 20-inch wheels. Once that is settled, the decision becomes choosing the right tire within the correct size for load needs, road use, and overall truck setup.
245/75R17 is a metric radial size in which 245 identifies the nominal section width in millimeters, 75 is the aspect ratio, R marks radial construction, and 17 is the rim diameter in inches. On the 2016 GMC Trucks Sierra 2500 HD, this size belongs to specific sub-model and wheel combinations rather than every configuration. Available product details in this size show an LT-format truck tire from BFGoodrich with raised white letter sidewalls in the All Terrain TA KO2 series. This size is worth considering when the truck is equipped with 17-inch wheels and the intended use calls for proper heavy-duty tire selection.
265/70R18 is a metric radial size where 265 is the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 18 designates an 18-inch rim. This size appears across multiple 2016 GMC Trucks Sierra 2500 HD sub-models, making it one of the more widely used fitments in the range. Its role in the lineup makes it especially important to verify whether the truck still has its correct 18-inch wheels rather than assuming by trim name alone. Buyers comparing this size should focus on wheel diameter, load requirements, and the truck's present configuration.
265/60R20 follows the same metric radial format, with 265 for nominal section width in millimeters, 60 for aspect ratio, R for radial construction, and 20 for rim diameter in inches. On the 2016 GMC Trucks Sierra 2500 HD, this size is tied to certain higher-wheel-diameter configurations rather than the full model line. Its lower-profile format relative to the other listed sizes makes wheel confirmation especially important before selection. This is the size to evaluate when the truck is already running 20-inch wheels and the goal is to keep the correct fitment category for that setup.
Sub-model fitment on the 2016 GMC Trucks Sierra 2500 HD is not one-size-fits-all, because different trims can use different wheel diameters and more than one tire size. Checking the exact sub-model is important, but confirming the truck's current wheels matters just as much before choosing a tire.

2016 GMC Trucks Sierra 2500 HD Base
The 2016 GMC Trucks Sierra 2500 HD Base uses either a 245/75R17 or 265/70R18 radial fitment, so wheel diameter is the key detail to confirm first. Once that is verified, tire selection becomes a matter of choosing the right product within the correct size for the truck's working use and load demands.
The 2016 GMC Trucks Sierra 2500 HD Denali uses either 265/60R20 or 265/70R18 radial tires depending on wheel setup. That makes it important to inspect the truck's actual rims before comparing tire options, especially if the vehicle has had wheel changes or trim-based assumptions no longer match the current configuration.
The 2016 GMC Trucks Sierra 2500 HD SLE has the broadest fitment range here, using 245/75R17, 265/70R18, or 265/60R20 radial tires. Tire choice starts with confirming which wheel package is on the truck now, then narrowing the decision to the proper size for use, load rating, and overall setup.
The 2016 GMC Trucks Sierra 2500 HD SLT uses either 265/60R20 or 265/70R18 radial tires, depending on the wheel configuration. That means a trim badge alone is not enough for tire selection, and the safest starting point is matching the tire size to the actual rim diameter on the truck.
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 2016 GMC Trucks Sierra 2500 HD?
A 2016 GMC Trucks Sierra 2500 HD can use three primary tire sizes: 245/75R17, 265/70R18, and 265/60R20. All three are radial fitments, but they do not apply to every truck in the same way because fitment varies by sub-model and wheel package.
The practical first step is checking the truck's exact trim and actual wheel diameter before choosing a tire. A Base, Denali, SLE, or SLT model may share one size with another trim, but the truck still has to be matched to its present 17-inch, 18-inch, or 20-inch wheels.
What size rim does a 2016 GMC Trucks Sierra 2500 HD use?
The 2016 GMC Trucks Sierra 2500 HD uses three rim diameters across its tire fitments: 17-inch, 18-inch, and 20-inch. The 245/75R17 size uses a 17-inch rim, 265/70R18 uses an 18-inch rim, and 265/60R20 uses a 20-inch rim.
Rim diameter is the most important fitment check on this truck because the model range spans multiple wheel sizes. Before comparing tread design, sidewall style, or brand, match the tire size to the wheel that is actually on the truck now, especially if it may have had wheel changes over time.
Do all 2016 GMC Trucks Sierra 2500 HD sub-models use the same tire size?
No, the 2016 GMC Trucks Sierra 2500 HD sub-models do not all use the same tire size. Base models use 245/75R17 or 265/70R18, Denali uses 265/60R20 or 265/70R18, SLE can use all three sizes, and SLT uses 265/60R20 or 265/70R18.
That variation means trim name and wheel setup need to be checked together. An SLE may be fitted very differently from a Denali or Base truck, and even within the same trim, more than one size may apply, so the actual wheel and current tire markings should guide the selection.
Choosing the Right Tire
What should I consider when choosing a 245/75R17 tire for a 2016 GMC Trucks Sierra 2500 HD?
Start with the correct size, construction, and wheel match. For the 2016 GMC Trucks Sierra 2500 HD, 245/75R17 is a radial fitment used on specific configurations, and the available product details in this size include an LT-format BFGoodrich All Terrain TA KO2 with a 3,195 lbs @ 80 psi maximum load capacity.
Selection should then focus on how the truck is used. Rim-width compatibility, sidewall style, load needs, and tread character all matter on a heavy-duty pickup, so compare the tire against the truck's working role rather than choosing by appearance or trim name alone.
What sidewall styles are available for 2016 GMC Trucks Sierra 2500 HD tires?
The available product details for the 2016 GMC Trucks Sierra 2500 HD show a raised white letter sidewall, listed as RWL, in 245/75R17. That gives this truck at least one sidewall appearance choice with a more traditional light-truck presentation than a plain blackwall look.
Sidewall style does not change the need to match the correct tire size and wheel diameter first. Once fitment is confirmed, sidewall appearance becomes part of the visual decision, especially for owners who want a more purposeful truck look without stepping outside the proper size category.
What brands offer tires for the 2016 GMC Trucks Sierra 2500 HD?
BFGoodrich is represented in the current product selection for the 2016 GMC Trucks Sierra 2500 HD, with a 245/75R17 All Terrain TA KO2 radial tire. That product uses an LT-format specification and a raised white letter sidewall, which gives it a distinct heavy-duty truck character.
Brand alone should not be the only deciding factor on a Sierra 2500 HD. The better comparison points are the correct size for the truck, the intended use, the tire's load-related specifications, and whether the wheel width and overall setup match the tire being considered.
Restoration & Appearance
Which tire should I choose for a period-style 2016 GMC Trucks Sierra 2500 HD?
A period-style approach on a 2016 GMC Trucks Sierra 2500 HD starts with keeping the truck in its correct size family for the wheel diameter actually installed. Since this is a modern heavy-duty pickup with radial fitments, the most authentic-looking choice usually comes from matching the proper 17-inch, 18-inch, or 20-inch setup first.
Appearance choices should come after fitment is settled. A raised white letter sidewall can give a more traditional truck presentation in the available 245/75R17 offering, but the visual goal still needs to be balanced with load capability, intended use, and the truck's present wheel package.
Does correct tire fitment matter for a 2016 GMC Trucks Sierra 2500 HD restoration?
Yes, correct tire fitment matters because the 2016 GMC Trucks Sierra 2500 HD was offered with multiple tire and wheel combinations. Using the right size for the truck's trim and wheel diameter keeps the stance, wheel-to-tire relationship, and overall presentation closer to the way the truck was configured in service.
Restoration-minded owners should verify current wheels rather than relying only on badges or assumptions about trim. If exact originality matters, compare the truck against build documentation, window-sticker information, or marque-specific references, then choose a tire that supports both the intended look and the truck's working requirements.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 GMC Trucks Sierra 2500 HD?
Yes, modifications can affect tire fitment on a 2016 GMC Trucks Sierra 2500 HD. Aftermarket wheels, suspension lifts or lowering changes, altered offsets, and body modifications can all change how a 245/75R17, 265/70R18, or 265/60R20 tire sits in relation to steering, suspension, and fender clearance.
That matters even when the tire size itself is one of the proper fitments for the model. A truck that no longer has its original wheels or ride height should be checked carefully for clearance at full steering lock and under load before settling on any replacement tire.
What should I inspect before driving a 2016 GMC Trucks Sierra 2500 HD on new tires?
Inspect wheel diameter, wheel width, tire pressure, lug hardware, and basic tire condition before putting a 2016 GMC Trucks Sierra 2500 HD into regular road use. It is also wise to confirm that the installed tire size matches the truck's actual wheel setup and that there are no cuts, bulges, or signs of bead seating problems.
A heavy-duty pickup places meaningful demands on its tires, especially when hauling or towing is part of the plan. After installation, recheck clearance, watch for any rubbing during turning or suspension movement, and keep an eye on air retention during the first several drives.
How often should tires on a 2016 GMC Trucks Sierra 2500 HD be inspected?
Tires on a 2016 GMC Trucks Sierra 2500 HD should be inspected regularly, not just when tread looks worn. Pressure loss, uneven wear, cracking, punctures, and sidewall damage can develop gradually, and a heavy-duty truck can magnify those issues if it is worked, loaded, or driven long distances.
A quick visual and pressure check before routine use is a smart habit, with a more thorough inspection before towing, hauling, or extended highway driving. Trucks that sit for long periods still deserve attention, since low use can hide age-related problems that only become obvious once the vehicle is back on the road.
