The 2015 Chevrolet Trucks Silverado 3500 HD LTZ sits in the heavy-duty pickup segment where wheel, tire, and load-related details matter more than they do on lighter trucks. Buyers looking at this exact Silverado are usually balancing work use, towing, seasonal capability, and the need to keep the truck matched to its actual wheel and axle setup. Tire fitment centers on two radial sizes, 235/80R17 and 265/70R18, and the correct choice depends first on whether the truck is a DRW or a non-DRW LTZ configuration. That makes wheel diameter and sub-model confirmation the key first step before comparing available tire options or planning any replacement.
Which Tire Size Is Right for The 2015 Chevrolet Trucks Silverado 3500 HD LTZ
Two primary tire sizes apply to the 2015 Chevrolet Trucks Silverado 3500 HD LTZ, and they do not serve the same configurations. Fitment varies by sub-model and wheel diameter, with 17-inch and 18-inch rim applications both represented. Before choosing a tire, confirm whether the truck is a DRW or non-DRW setup and verify the wheel diameter currently on the vehicle, especially if wheels have ever been changed.
235/80R17 is a metric radial size that uses a 235-millimeter section width, an 80-series aspect ratio, radial construction, and a 17-inch rim diameter. On this Silverado 3500 HD LTZ application, it serves the DRW configurations, so it is tied to a specific wheel and truck setup rather than the full model range. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with an RBL sidewall style and an all-terrain character. This size is the right one to evaluate when the truck is equipped with the correct 17-inch DRW wheel package.
265/70R18 is a metric radial size with a 265-millimeter section width, a 70-series aspect ratio, radial construction, and an 18-inch rim diameter. For this 2015 Chevrolet Trucks Silverado 3500 HD LTZ, that size applies to the non-DRW LTZ Base and Snow Plow Prep Package configurations. Its role is different from the 17-inch fitment, so the first concern is matching the truck's actual wheel diameter and sub-model. This is the size to pursue when the truck carries the original-style 18-inch single-rear-wheel setup or an equivalent wheel arrangement.
2015 Chevrolet Trucks Silverado 3500 HD LTZ Sub-Model Tires
Tire fitment changes across the covered 2015 Chevrolet Trucks Silverado 3500 HD LTZ sub-models, so the exact configuration matters before any tire is selected. The main split is between DRW trucks using a 17-inch radial size and non-DRW trucks using an 18-inch radial size.

2015 Chevrolet Trucks Silverado 3500 HD LTZ (DRW)
The 2015 Chevrolet Trucks Silverado 3500 HD LTZ (DRW) uses the 235/80R17 radial size rather than the 18-inch fitment found on other LTZ variations. That makes wheel confirmation especially important before replacement, particularly on trucks that may have seen wheel, tire, or axle-related changes over time.
The 2015 Chevrolet Trucks Silverado 3500 HD LTZ Base uses the 265/70R18 radial size. Tire selection here starts with confirming that the truck still has the correct 18-inch wheel setup, then comparing choices within that size based on intended use and overall tire design.

The 2015 Chevrolet Trucks Silverado 3500 HD LTZ Snow Plow Prep Pkg. also uses the 265/70R18 radial size. Since this package can influence how the truck is used, it is worth checking wheel condition, load needs, and clearance before moving from a worn set to a replacement tire.
2015 Chevrolet Trucks Silverado 3500 HD LTZ Snow Plow Prep Pkg. (DRW)
The 2015 Chevrolet Trucks Silverado 3500 HD LTZ Snow Plow Prep Pkg. (DRW) uses the 235/80R17 radial size. That places it with the dual-rear-wheel 17-inch fitment, so replacement decisions should stay focused on the truck's actual DRW wheel setup and intended service demands.
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:

Common questions for the 2015 Chevrolet Trucks Silverado 3500 HD LTZ usually focus on identifying the correct tire size by sub-model, confirming 17-inch versus 18-inch wheel fitment, and checking tire condition, wheel setup, and maintenance before the truck goes back into regular road use.
Tire Size & Fitment
What tire size fits a 2015 Chevrolet Trucks Silverado 3500 HD LTZ?
The 2015 Chevrolet Trucks Silverado 3500 HD LTZ uses either 235/80R17 or 265/70R18, and both are radial sizes. The 235/80R17 size applies to DRW versions, while 265/70R18 applies to the LTZ Base and Snow Plow Prep Package non-DRW versions.
That means the right tire is tied to the truck's exact configuration rather than the LTZ badge alone. Start by confirming whether the truck is dual rear wheel or not, then verify the actual wheel diameter on the vehicle before comparing tires, especially if it has seen replacement wheels or previous tire changes.
What size rim does a 2015 Chevrolet Trucks Silverado 3500 HD LTZ use?
This Silverado 3500 HD LTZ uses either a 17-inch or 18-inch rim, depending on the sub-model. The 235/80R17 fitment uses a 17-inch rim, while the 265/70R18 fitment uses an 18-inch rim.
Rim diameter is the first thing to verify because a 17-inch tire and an 18-inch tire are not interchangeable. Check the wheel size stamped on the wheel or confirm the current tire size on the truck, then make sure the wheel setup matches the intended tire before moving on to construction, load, or tread-pattern decisions.
Why does the 2015 Chevrolet Trucks Silverado 3500 HD LTZ have more than one tire size?
More than one tire size appears because the 2015 Chevrolet Trucks Silverado 3500 HD LTZ was offered in different sub-model configurations. DRW versions use 235/80R17, while non-DRW LTZ Base and Snow Plow Prep Package versions use 265/70R18.
The practical takeaway is that the tire decision starts with identifying the exact truck setup, not just the model name. A Silverado that has been modified, had wheels replaced, or changed use over time should be checked carefully so the replacement tire matches the current wheel diameter and the truck's real operating configuration.
Choosing the Right Tire
What should I consider when choosing a 235/80R17 tire for a 2015 Chevrolet Trucks Silverado 3500 HD LTZ?
For a 2015 Chevrolet Trucks Silverado 3500 HD LTZ using 235/80R17, start with the correct DRW fitment and 17-inch wheel diameter. Then compare the tire's construction, load capacity, rim-width compatibility, sidewall style, and tread character to the truck's actual use.
A 235/80R17 option in this application includes a BFGoodrich radial all-terrain design with an RBL sidewall, a 3,085-pound maximum load capacity at 80 psi, and a 6.0- to 7.5-inch rim-width range. Those details matter when the truck is expected to handle work duties, towing, or mixed-surface driving rather than purely cosmetic use.
What brands offer tires for the 2015 Chevrolet Trucks Silverado 3500 HD LTZ?
BFGoodrich is represented among the available products for this 2015 Chevrolet Trucks Silverado 3500 HD LTZ fitment range. The visible product coverage is centered on the 235/80R17 size used on DRW configurations.
Brand comparison is only useful after confirming the truck's exact size and wheel setup. Once that is settled, look at the rest of the tire details that affect real use, including rim-width range, sidewall presentation, tread type, load specification, and whether the truck is being kept for work duty, seasonal service, or general road use.
What sidewall styles are available for 2015 Chevrolet Trucks Silverado 3500 HD LTZ tires?
An RBL sidewall style is available in the product selection for this 2015 Chevrolet Trucks Silverado 3500 HD LTZ. That sidewall treatment appears on the 235/80R17 BFGoodrich all-terrain option tied to the DRW fitment.
Sidewall style should be considered alongside the more important fitment factors of correct size, wheel diameter, and load-related suitability. Once those basics are confirmed, the sidewall treatment becomes part of the truck's overall presentation, especially for owners who want a certain visual balance between work-truck character and a cleaner finished look.
Restoration & Appearance
Does correct tire fitment matter for a 2015 Chevrolet Trucks Silverado 3500 HD LTZ restoration?
Correct tire fitment matters because this Silverado 3500 HD LTZ uses different sizes across its covered sub-models, with 235/80R17 for DRW versions and 265/70R18 for certain non-DRW versions. Keeping the wheel diameter and tire size matched to the truck's actual configuration preserves a more coherent, proper-looking stance.
On a later heavy-duty truck like this one, appearance and function are closely connected. A restoration-minded owner should confirm the truck's present wheel setup, avoid mixing in an incorrect diameter for looks alone, and use model-specific references if the goal is to match a particular trim, package, or original delivery presentation.
How does tire construction affect the appearance of a restored 2015 Chevrolet Trucks Silverado 3500 HD LTZ?
The primary fitments for the 2015 Chevrolet Trucks Silverado 3500 HD LTZ are radial tires, so the truck's intended visual presentation already centers on modern radial construction rather than vintage bias-ply styling. In practical terms, appearance differences are more likely to come from tread design, sidewall treatment, and wheel size than from changing construction type.
That makes the correct size and wheel pairing the first appearance decision. After that, details such as an RBL sidewall or an all-terrain tread can push the truck toward a more work-oriented or more aggressive look, while still keeping the overall setup aligned with the heavy-duty character of the Silverado 3500 HD LTZ.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Chevrolet Trucks Silverado 3500 HD LTZ?
Yes, modifications can affect tire fitment on a 2015 Chevrolet Trucks Silverado 3500 HD LTZ. Changes to wheels, offsets, suspension height, rear-wheel configuration, or body clearance can all alter how a 235/80R17 or 265/70R18 tire sits and operates on the truck.
A truck with aftermarket wheels or suspension changes should be checked for wheel diameter, wheel width, clearance at full steering lock, and space around suspension and body components. On heavy-duty applications, it is also smart to confirm that the replacement tire still suits the truck's intended load and service demands before regular road use.
What should I inspect before driving a 2015 Chevrolet Trucks Silverado 3500 HD LTZ on new tires?
Before road use, inspect tire pressure, bead seating, lug torque, valve stems, and the overall condition of the wheels. It is also worth checking the tires themselves for shipping damage, irregular mounting issues, or any visible cuts, bulges, or air loss after installation.
A heavy-duty truck like the Silverado 3500 HD LTZ also deserves a quick clearance check with the steering turned and the suspension loaded normally. That step is especially important if the truck has changed wheels, carries work equipment, or operates in demanding conditions where any rubbing, mismatch, or inflation problem can become obvious very quickly.
How should tires on a collector or low-use 2015 Chevrolet Trucks Silverado 3500 HD LTZ be maintained?
Low-use tires on a 2015 Chevrolet Trucks Silverado 3500 HD LTZ should still be inspected regularly for air loss, tread wear, sidewall cracking, cuts, and weather-related aging. Even when a truck is not driven often, tire condition can decline with time, storage conditions, and long periods of sitting.
Pressure checks and visual inspections should be part of routine upkeep, not just pre-trip preparation. It also helps to store the truck away from prolonged sunlight, standing moisture, and ozone sources, and to look over the wheels and valve stems at the same time so the complete tire-and-wheel assembly stays ready for safe road use.
