The 2015 Chevrolet Trucks Silverado 1500 sits in the modern full-size pickup market where trim level, wheel package, and intended use can change the tire decision more than the truck’s basic platform. Buyers often approach this generation looking for a combination of everyday road manners, work-truck practicality, and a stance that still suits the Silverado’s broad-shouldered styling. Tire fitment spans five primary radial sizes, from 17-inch applications up to 22-inch options depending on sub-model and wheel setup. That makes this page less about one universal size and more about confirming the exact trim and rim diameter before comparing available tire choices. Once that is settled, the focus shifts to load capacity, sidewall style, and how the truck is actually driven.
Which Tire Size Is Right for The 2015 Chevrolet Trucks Silverado 1500
The 2015 Chevrolet Trucks Silverado 1500 uses five primary tire sizes, and the right one depends first on the truck’s exact sub-model and wheel diameter. All of these fitments are radial, but they span 17-inch, 18-inch, 20-inch, and 22-inch rims. Before choosing a tire, confirm whether the truck is a WT, LS, LT, LTZ, High Country, or SSV, and verify the actual wheel package on the vehicle.
Fit(s): High Country, LT (20 Inch Option), and LTZ
Construction: Radial|Rim: 20 in
275/55R20 is a metric radial size with a 275-millimeter section width, a 55-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2015 Chevrolet Trucks Silverado 1500, this size is part of the larger-wheel fitment range used on certain upper trims and wheel-option packages. Its role in the lineup is to pair the Silverado with a 20-inch wheel while keeping an overall tire diameter close to other factory-style fitments. This is a size to evaluate carefully when the truck has been optioned for a larger-wheel appearance rather than the 17-inch or 18-inch setups.
Fit(s): High Country, LT (22 Inch Option), and LTZ
Construction: Radial|Rim: 22 in
285/45R22 is a metric radial tire size that uses a 285-millimeter section width, a 45-series profile, and a 22-inch rim diameter. For the 2015 Chevrolet Trucks Silverado 1500, it represents the largest wheel-package fitment in this group and is tied to specific upscale or optioned configurations rather than the truck line as a whole. The lower-profile sidewall and 22-inch wheel requirement make wheel confirmation especially important before selection. This size is most relevant when preserving the truck’s existing 22-inch setup instead of converting to a different wheel diameter.
255/70R17 is a metric radial size with a 255-millimeter section width, a 70-series profile, and a 17-inch rim diameter. On the 2015 Chevrolet Trucks Silverado 1500, it belongs to the smaller-wheel fitment group used on several practical trims, making it a common choice for owners focused on standard-duty road use and straightforward replacement. Its dimensions place it alongside other 17-inch Silverado applications, but it is not the same as the wider 265/70R17 option. This size should be chosen only after confirming which 17-inch setup is actually on the truck.
265/70R17 is a metric radial size with a 265-millimeter section width, a 70-series aspect ratio, and a 17-inch rim. For the 2015 Chevrolet Trucks Silverado 1500, this size appears on several 17-inch applications and is the one size here with currently visible product choices from BFGoodrich in the All-Terrain T/A KO2 line with raised white letter sidewalls. Those options differ in load capacity, weight, and service rating even though they share the same basic size. It is a strong size to examine closely when the truck is used for mixed on-road and light off-road duty.
265/65R18 is a metric radial tire size that combines a 265-millimeter section width with a 65-series profile on an 18-inch rim. On the 2015 Chevrolet Trucks Silverado 1500, it fills the middle ground between the 17-inch work-oriented setups and the larger 20-inch or 22-inch wheel packages. That makes it particularly relevant on trims and configurations that balance a fuller wheel appearance with practical sidewall height. This size is worth considering only when the truck already has the correct 18-inch wheels, since the Silverado also uses several other diameters that are not interchangeable by size alone.
2015 Chevrolet Trucks Silverado 1500 Sub-Model Tires
Tire fitment on the 2015 Chevrolet Trucks Silverado 1500 varies significantly by sub-model and wheel package. Checking the exact trim matters because this truck can use 17-inch, 18-inch, 20-inch, or 22-inch radial sizes depending on how it was equipped.

2015 Chevrolet Trucks Silverado 1500 High Country
The High Country uses larger-wheel radial fitments, with 20-inch and 22-inch applications in this range. Tire selection starts with confirming which wheel package is on the truck, then comparing choices that suit its existing appearance and intended road use.
The LS uses 17-inch radial tire fitments and may be equipped with either of the two 17-inch sizes used on this Silverado lineup. That means the safest starting point is the actual size on the truck’s wheels, not the trim badge alone.
The LT can use either of the standard 17-inch radial sizes in its regular form, so there is already more than one fitment path within this trim. Tire choice should begin with the wheel and tire size currently installed before moving on to tread style or load specification.
2015 Chevrolet Trucks Silverado 1500 LT (18 Inch Option)
The LT with the 18 Inch Option uses the 18-inch radial fitment rather than the 17-inch, 20-inch, or 22-inch alternatives in the Silverado range. For replacement, the key is staying with the correct 18-inch sizing and confirming wheel compatibility before comparing tire features.
2015 Chevrolet Trucks Silverado 1500 LT (20 Inch Option)
The LT with the 20 Inch Option moves to the 20-inch radial setup used on selected Silverado 1500 configurations. That makes wheel diameter the first checkpoint, followed by choosing a tire that matches how the truck is driven and presented.
2015 Chevrolet Trucks Silverado 1500 LT (22 Inch Option)
The LT with the 22 Inch Option uses the Silverado’s 22-inch radial fitment, which is separate from the smaller-diameter LT configurations. Owners should confirm that the truck still has its 22-inch wheels before selecting a replacement tire in this size.
The LTZ has the widest fitment spread here, using 18-inch, 20-inch, or 22-inch radial sizes depending on wheel package. Tire selection for an LTZ depends less on the trim name itself and more on verifying the actual wheel diameter mounted on the truck.
The SSV uses 17-inch radial fitments and shares the same general two-size pattern seen on several other Silverado sub-models. For a correct replacement decision, confirm which of the two 17-inch sizes is installed and whether the truck still retains its original wheel setup.
The WT uses one of the Silverado’s 17-inch radial fitments, with two possible sizes associated with this work-oriented trim. That makes it important to inspect the wheel and tire combination on the truck instead of assuming every WT uses the same exact 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.

Silverado 1500 tire questions usually come down to trim-specific sizing, wheel diameter, and choosing the right radial tire for the truck’s actual use. The answers below focus on fitment, available 17-inch product choices, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2015 Chevrolet Trucks Silverado 1500?
The 2015 Chevrolet Trucks Silverado 1500 uses five primary radial tire sizes: 255/70R17, 265/70R17, 265/65R18, 275/55R20, and 285/45R22. The correct size depends on the truck’s sub-model and wheel package, so there is not one universal tire size for every Silverado 1500 in this model year.
Start by checking the exact trim and the wheel diameter actually on the truck, because several sub-models can be equipped with more than one size. A replacement decision should also take into account whether the truck still has its original wheels, since aftermarket changes can alter what size is appropriate.
What size rim does a 2015 Chevrolet Trucks Silverado 1500 use?
The 2015 Chevrolet Trucks Silverado 1500 uses four rim diameters across these fitments: 17-inch, 18-inch, 20-inch, and 22-inch. The 255/70R17 and 265/70R17 sizes use 17-inch rims, 265/65R18 uses an 18-inch rim, 275/55R20 uses a 20-inch rim, and 285/45R22 uses a 22-inch rim.
Rim diameter should be confirmed before anything else, because a tire cannot be matched correctly without the right wheel size. Once diameter is settled, check the exact tire size on the vehicle and make sure the wheel setup has not been changed from its original trim or option-package configuration.
Why does the 2015 Chevrolet Trucks Silverado 1500 have more than one tire size?
This Silverado 1500 spans several trims and wheel packages, so different versions use different tire and rim combinations. WT, LS, LT, SSV, LTZ, and High Country models do not all share the same setup, and some trims can be paired with multiple wheel diameters depending on option package.
That means the tire choice is tied to how the truck was equipped rather than the model name alone. A Silverado with 17-inch wheels needs a different fitment path than one with 20-inch or 22-inch wheels, so the actual sub-model and current wheel package should be verified before selecting replacements.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2015 Chevrolet Trucks Silverado 1500?
For a 2015 Chevrolet Trucks Silverado 1500 using 265/70R17, the first priorities are confirming that this is the correct size for the truck and matching the tire to the intended use. Available 265/70R17 products include BFGoodrich All-Terrain T/A KO2 options, and they differ in load capacity, weight, and service specification.
A close comparison matters because two tires in the same size can still suit different duty levels. Check the wheel’s rim width as well, since the available 265/70R17 products call for a 7.0- to 9.0-inch rim, and make sure the chosen tire aligns with how the Silverado is loaded and driven.
What sidewall styles are available for 2015 Chevrolet Trucks Silverado 1500 tires?
Among the currently visible product choices for this Silverado 1500, 265/70R17 is available with an RWL sidewall, meaning raised white letters. That gives owners using this 17-inch fitment a more traditional light-truck sidewall presentation than a plain black sidewall would provide.
Sidewall style is mainly an appearance decision once the correct size and tire specification are settled. A raised white letter tire can change the truck’s visual character noticeably, so it helps to decide whether the goal is a cleaner understated look or a more pronounced all-terrain, enthusiast-oriented presentation.
What brands offer tires for the 2015 Chevrolet Trucks Silverado 1500?
The currently visible product options for the 2015 Chevrolet Trucks Silverado 1500 are from BFGoodrich in the 265/70R17 size. Those products are part of the All-Terrain T/A KO2 family and give owners using that 17-inch fitment a recognizable all-terrain radial choice.
Brand selection only matters after the correct tire size has been confirmed for the specific Silverado trim and wheel package. Since this truck uses several different primary sizes, an owner with 18-inch, 20-inch, or 22-inch wheels should verify size first rather than assuming a product shown for one fitment applies across the entire lineup.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Chevrolet Trucks Silverado 1500?
A period-style choice for a 2015 Chevrolet Trucks Silverado 1500 usually starts with keeping the truck in the tire size and wheel diameter that match its trim and option package. Because this model uses 17-inch, 18-inch, 20-inch, and 22-inch fitments, the right visual result depends first on preserving the truck’s existing stance and wheel presentation.
Appearance comes from more than size alone, so sidewall treatment and tire character also matter once fitment is confirmed. Owners aiming for a showroom-era look should compare the truck against original sales material, photos, or marque-specific references before making changes that alter the Silverado’s factory-era visual balance.
Does correct tire fitment matter for a 2015 Chevrolet Trucks Silverado 1500 restoration?
Correct tire fitment matters because the 2015 Chevrolet Trucks Silverado 1500 was offered with several distinct wheel and tire combinations, and each one affects the truck’s stance and overall appearance. Using the wrong diameter or profile can make a restoration-oriented truck look out of proportion even if the tire physically mounts.
A restoration-minded approach should begin with the truck’s exact trim and wheel package rather than a generic Silverado size search. Matching the proper size, maintaining the intended wheel diameter, and choosing a sidewall style that suits the truck’s original-era character will usually produce a more coherent finished result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Chevrolet Trucks Silverado 1500?
Yes. Wheel changes, altered offsets, suspension lifts or drops, and other chassis modifications can affect tire fitment on a 2015 Chevrolet Trucks Silverado 1500 even when the basic tire size sounds close to stock. This matters especially on a truck that already has multiple factory wheel diameters and trim-specific fitment paths.
A modified Silverado should be checked for wheel diameter, wheel width, tire clearance, and steering clearance before a new tire is chosen. The safest approach is to confirm the truck’s current setup in real terms instead of relying only on original trim information, particularly if the vehicle has changed hands or been customized.
What should I inspect before driving a 2015 Chevrolet Trucks Silverado 1500 on new tires?
Before driving, inspect the Silverado’s wheel size, lug torque, inflation pressure, and visible clearance at the fenders and suspension. It is also worth checking for rubbing at full steering lock and confirming that the tire size on the truck matches the wheel diameter, since this model year uses several different factory-style combinations.
A short initial road test can reveal vibration, pull, or contact issues that are easier to correct early. Owners should also keep an eye on air loss and tread wear during the first few drives, because uneven wear can point to alignment, suspension, or wheel-condition problems rather than the tire itself.
How often should tires on a 2015 Chevrolet Trucks Silverado 1500 be inspected?
Tires on a 2015 Chevrolet Trucks Silverado 1500 should be inspected regularly, not just when they look visibly worn. Routine checks should include tread condition, inflation pressure, cuts, bulges, irregular wear, and any signs of sidewall damage, especially if the truck sees towing, rough roads, or seasonal storage.
A Silverado that is driven less often still needs attention because low-use vehicles can develop age-related issues that are easy to miss. Inspecting the tires before longer trips and at regular intervals helps catch air loss, cracking, or clearance problems early, which is especially important when the truck uses larger optional wheel packages.
