The 2015 Chevrolet Trucks Silverado 2500 HD sits in the modern heavy-duty pickup market where work capability, towing demands, and trim-dependent wheel packages all shape tire choice. Buyers looking at this truck usually are not sorting out whether it is a collector piece, but they still need fitment that matches the truck’s exact setup. This Silverado 2500 HD uses radial tire fitments, with four primary sizes spread across 17-inch, 18-inch, and 20-inch wheels. That makes the real decision less about vintage-style construction and more about confirming the sub-model and wheel diameter first. Once that is settled, the focus shifts to load-minded tire selection, sidewall presentation, and road-use needs.
Which Tire Size Is Right for The 2015 Chevrolet Trucks Silverado 2500 HD
The 2015 Chevrolet Trucks Silverado 2500 HD uses four primary tire sizes, and they are tied to different sub-model and wheel combinations. Before choosing a tire, the first step is confirming the truck’s exact sub-model and wheel diameter, since this fitment spans 17-inch, 18-inch, and 20-inch rims. After that, the choice becomes more specific: selecting the right radial size and comparing available load-related specifications, rim-width compatibility, and tread character within that size.
Fit(s): High Country, High Country Snow Plow Prep Pkg., LT, LT Snow Plow Prep Pkg., LTZ, and LTZ Snow Plow Prep Pkg.
Construction: Radial|Rim: 20 in
265/60R20 is a metric radial size in which 265 is the section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2015 Chevrolet Trucks Silverado 2500 HD, this size is part of the truck’s modern radial fitment and belongs on a 20-inch wheel setup. Its lower-profile look compared with the 17-inch and 18-inch sizes makes wheel confirmation especially important. This size is the right place to start when the truck is equipped with the larger 20-inch factory-style wheel package.
245/75R17 is a metric radial size with a 245-millimeter section width, a 75-series aspect ratio, and a 17-inch rim diameter. For the 2015 Chevrolet Trucks Silverado 2500 HD, it is one of the 17-inch fitments and suits trucks equipped with that narrower tire-and-wheel combination. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewall styling. This is a useful size to evaluate when maintaining a 17-inch setup and when rim-width and load-capacity details matter as much as the basic size itself.
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 required wheel diameter. On the 2015 Chevrolet Trucks Silverado 2500 HD, this size is another 17-inch fitment, but with a wider section than 245/75R17. Product choices in this size include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls and differing load-capacity specifications. It is the right size to consider only when the truck is using the 17-inch wheel package matched to this broader tire profile.
265/70R18 is a metric radial size with a 265-millimeter section width, a 70-series profile, and an 18-inch wheel requirement. For the 2015 Chevrolet Trucks Silverado 2500 HD, this size belongs to trucks equipped with 18-inch wheels and appears across several sub-models. Its meaning is straightforward, but it still needs to be matched to the actual wheel on the truck rather than assumed from trim name alone. This size becomes the correct path when the Silverado has the 18-inch setup and the buyer wants to stay with the truck’s primary radial fitment.
2015 Chevrolet Trucks Silverado 2500 HD Sub-Model Tires
Sub-model fitment on the 2015 Chevrolet Trucks Silverado 2500 HD is not one-size-fits-all. Several trims use more than one tire size, so identifying the exact sub-model and confirming the truck’s actual wheel diameter are the two key steps before comparing tires.

2015 Chevrolet Trucks Silverado 2500 HD High Country
The 2015 Chevrolet Trucks Silverado 2500 HD High Country uses a single radial fitment tied to its 20-inch wheel setup. Tire selection is therefore more straightforward here, with the main focus shifting from size confirmation to choosing the right tire type and specification within that fitment.
2015 Chevrolet Trucks Silverado 2500 HD High Country Snow Plow Prep Pkg.
The High Country Snow Plow Prep Pkg. keeps the same single radial size used with the 20-inch wheel arrangement. That means the buyer can concentrate on selecting the proper tire within that size while still checking the truck’s actual wheel and intended work use before purchase.
The 2015 Chevrolet Trucks Silverado 2500 HD LT can use four different radial tire sizes, depending on how the truck is equipped. This sub-model makes wheel confirmation especially important, since tire choice cannot be narrowed down correctly until the 17-inch, 18-inch, or 20-inch setup is verified.
2015 Chevrolet Trucks Silverado 2500 HD LT Snow Plow Prep Pkg.
The LT Snow Plow Prep Pkg. uses multiple radial tire sizes rather than one universal fitment. Choosing correctly starts with confirming the truck’s installed wheel diameter, then comparing the available tires in that exact size for load-related specifications and intended use.
The 2015 Chevrolet Trucks Silverado 2500 HD LTZ uses two radial tire sizes across different wheel packages. Tire selection here depends on whether the truck is on the 18-inch or 20-inch setup, so the wheel itself matters more than assuming fitment from the trim badge alone.
2015 Chevrolet Trucks Silverado 2500 HD LTZ Snow Plow Prep Pkg.
The LTZ Snow Plow Prep Pkg. also spans two radial tire sizes, tied to different wheel diameters. The practical takeaway is simple: confirm the truck’s actual wheels first, then compare tires in that one size rather than trying to choose from the full Silverado 2500 HD range.
The 2015 Chevrolet Trucks Silverado 2500 HD WT uses three possible radial sizes across its covered wheel setups. That makes exact fitment a wheel-and-configuration question first, followed by product selection based on size, rim compatibility, and the truck’s work or road-use demands.
2015 Chevrolet Trucks Silverado 2500 HD WT Snow Plow Prep Pkg.
The WT Snow Plow Prep Pkg. uses two radial tire sizes rather than one shared fitment. Picking the right tire starts with confirming whether the truck has the 17-inch or 18-inch setup, then narrowing the choice to tires built for that exact size and use case.
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.

These 2015 Chevrolet Trucks Silverado 2500 HD tire FAQs focus on the questions that matter most for this truck: identifying the correct size by sub-model and wheel diameter, understanding radial fitment, comparing available tire choices, and checking the truck before regular road or work use.
Tire Size & Fitment
What tire size fits a 2015 Chevrolet Trucks Silverado 2500 HD?
The 2015 Chevrolet Trucks Silverado 2500 HD uses four primary tire sizes: 245/75R17, 265/70R17, 265/70R18, and 265/60R20. All of them are radial sizes, and the correct one depends on the truck’s exact sub-model and wheel package rather than the model name alone.
The most practical way to narrow it down is to confirm the truck’s actual wheel diameter first, then match the tire size to that setup. Since several Silverado 2500 HD trims can use more than one size, checking the tire placard, existing tire size, and wheel measurement is more reliable than guessing by trim badge.
What size rim does a 2015 Chevrolet Trucks Silverado 2500 HD use?
The 2015 Chevrolet Trucks Silverado 2500 HD uses 17-inch, 18-inch, and 20-inch rim diameters across its covered fitments. Those rim sizes pair with 245/75R17 or 265/70R17, 265/70R18, and 265/60R20 respectively, depending on the truck’s exact configuration.
Rim diameter is the first fitment check because a tire must match the wheel exactly at that point. A 17-inch tire cannot be mounted on an 18-inch or 20-inch wheel, even if the truck is the same year and model. Looking at the wheel size and the current tire sidewall usually answers this question quickly.
Why does the 2015 Chevrolet Trucks Silverado 2500 HD have more than one tire size?
This Silverado 2500 HD spans multiple trims and wheel packages, so it does not rely on one universal tire size. Depending on the sub-model, the truck may use a 17-inch, 18-inch, or 20-inch wheel, which is why several radial sizes apply across the model range.
That variation matters because the correct tire is tied to the actual wheel setup on the truck, not just the vehicle name. LT, WT, LTZ, and snow-plow-prep versions can overlap in some sizes while differing in others. Confirming the exact sub-model helps, but confirming the installed wheel diameter matters even more.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Chevrolet Trucks Silverado 2500 HD?
Start with the correct primary size for the truck’s exact wheel and sub-model, since this Silverado 2500 HD uses four different radial fitments. After size is confirmed, compare the tire’s intended use, load-related specifications, rim-width compatibility, and whether the tread style matches how the truck is driven.
A work-oriented truck, a plow-prep truck, and a mainly road-driven truck can call for different priorities even when the tire size is the same. It also helps to compare the current wheel setup against any aftermarket changes before choosing. That keeps the decision focused on the truck you actually have, not a generic model listing.
What sidewall styles are available for 2015 Chevrolet Trucks Silverado 2500 HD tires?
Among the currently available products tied to this Silverado 2500 HD, the visible sidewall style is RWL, or raised white letter. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options offered in the supported 17-inch sizes shown here.
Sidewall style affects appearance more than fitment, but it still matters if the truck’s look is important to you. Raised white letters create a more aggressive, utility-oriented presentation than a plain blackwall. The key is to choose the correct size first, then decide whether that sidewall look suits the truck’s intended use and appearance.
What brands offer tires for the 2015 Chevrolet Trucks Silverado 2500 HD?
The available product selection shown for this 2015 Chevrolet Trucks Silverado 2500 HD includes BFGoodrich. In the covered 17-inch fitments, those tires appear in the All-Terrain T/A KO2 series and are built as radial truck tires with raised white letter sidewalls.
Brand matters less than getting the right size and wheel match first, especially on a truck with several possible fitments. Once size is confirmed, it makes sense to compare the available tires within that brand by series, load-related specification, and rim-width range. That approach keeps the choice practical instead of treating the brand name alone as the decision.
Restoration & Appearance
Does correct tire fitment matter for a 2015 Chevrolet Trucks Silverado 2500 HD restoration?
Yes. Even on a newer heavy-duty truck, correct tire fitment matters because wheel diameter, tire proportions, and sidewall presentation all affect how the vehicle sits and looks. A 2015 Chevrolet Trucks Silverado 2500 HD can wear 17-inch, 18-inch, or 20-inch tire-and-wheel combinations, so appearance starts with choosing the right size.
A restoration-minded owner should avoid treating all Silverado 2500 HD trims as identical. Matching the truck’s actual wheel setup preserves the intended stance far better than forcing a different size for looks alone. Sidewall treatment can then fine-tune the presentation, but the size itself remains the foundation of an authentic-looking result.
Which sidewall style suits a period-style 2015 Chevrolet Trucks Silverado 2500 HD?
For the currently available products tied to this truck, the sidewall style in view is raised white letter. On a 2015 Chevrolet Trucks Silverado 2500 HD, that look gives the truck a more assertive, off-road-oriented appearance than a plain black sidewall and fits naturally with the all-terrain tire character offered here.
Appearance choice still needs to come after fitment confirmation. The right sidewall style should complement the truck’s wheel size and intended presentation without pushing you into the wrong tire size. If a very specific original-delivery look matters, compare against vehicle photos, window-sticker records, or marque-specific references before making the final call.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Chevrolet Trucks Silverado 2500 HD?
Yes. Modifications can change how a tire fits on a 2015 Chevrolet Trucks Silverado 2500 HD even when the tire size itself is one of the normal options for the model. Aftermarket wheels, different wheel widths, suspension changes, leveling kits, or body alterations can all affect clearance and how the tire sits on the truck.
That is why the current setup matters more than the factory trim description once a truck has been altered. Checking wheel diameter is only the beginning; the wheel width and available clearance around steering, suspension, and fenders should also be reviewed. A truck with changes may need closer measurement before staying with any listed size.
What should I inspect before driving a 2015 Chevrolet Trucks Silverado 2500 HD on new tires?
Before regular road use, inspect the wheel size match, mounting condition, inflation pressure, valve stems, and general clearance at full steering travel. It is also smart to confirm that the tires are seated properly and that there is no contact with suspension parts, fender liners, or bodywork once the truck is back on the ground.
A heavy-duty pickup places real demands on its tires, so a quick visual check is not enough. Look for rubbing, uneven stance, or any sign that the truck’s current setup differs from what the tire size expects. After the first miles, recheck pressure and give the tires another inspection to catch any early fitment issues.
How should tires on a 2015 Chevrolet Trucks Silverado 2500 HD be maintained?
Tires on a 2015 Chevrolet Trucks Silverado 2500 HD should be maintained with regular pressure checks, visual inspections, and attention to tread wear across the full width of the tire. Any signs of cracking, bulges, cuts, punctures, or repeated air loss deserve prompt inspection before the truck is put back into normal service.
Because this is a heavy-duty truck, maintenance should also include watching for wear patterns that point to alignment issues, load-related stress, or suspension problems. Trucks that sit for long periods still need inspection, since age and storage conditions can affect tire condition even when tread looks good. Keeping the tires clean and properly inflated goes a long way.
