The 2014 RAM Trucks 3500 Laramie Longhorn sits at the luxury end of the heavy-duty pickup market, blending one-ton capability with upscale trim and a road presence that still reflects serious working-truck hardware. On this exact model, tire fitment is not one-size-fits-all, because single-rear-wheel and dual-rear-wheel configurations use different sizes and wheel diameters. Primary fitments include 275/70R18, 285/60R20, and 235/80R17, all in radial construction. Available choices lean toward all-terrain radial use, with sidewall presentation and wheel compatibility varying by size. The key first step is confirming whether the truck is SRW or DRW, then matching the tire to the actual wheel setup before comparing options.
Which Tire Size Is Right for The 2014 RAM Trucks 3500 Laramie Longhorn
Three tire sizes apply to the 2014 RAM Trucks 3500 Laramie Longhorn, and the right one depends on both sub-model and wheel diameter. Single-rear-wheel 4x2 and 4x4 trucks use either 275/70R18 or 285/60R20, while dual-rear-wheel versions use 235/80R17. Before choosing a tire, confirm whether the truck is SRW or DRW and verify the wheel diameter actually on the vehicle, especially if wheels have been changed.
In 275/70R18, the 275 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. This is a modern radial truck size used on single-rear-wheel versions of the 2014 RAM Trucks 3500 Laramie Longhorn with 18-inch wheels. Available options in this size include BFGoodrich's All-Terrain T/A KO2 with raised white letter sidewalls. It is the right size to evaluate when the truck is not a dually and carries the 18-inch wheel package.
In 285/60R20, the 285 identifies nominal section width in millimeters, the 60 is the aspect ratio, the R means radial, and the 20 denotes a 20-inch rim. This size belongs to single-rear-wheel 2014 RAM Trucks 3500 Laramie Longhorn configurations equipped with 20-inch wheels rather than the 18-inch setup. Its profile and wheel requirement make wheel confirmation especially important before selecting a tire. Use this size only after verifying that the truck is an SRW model and that the current wheels are actually 20-inch rims.
In 235/80R17, the 235 is the nominal section width in millimeters, 80 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. This size is used on dual-rear-wheel versions of the 2014 RAM Trucks 3500 Laramie Longhorn, making it distinct from the single-rear-wheel fitments. BFGoodrich offers this size in the All-Terrain T/A KO2 series with a black sidewall presentation. It is the size to focus on when the truck is a DRW configuration and still carries the matching 17-inch wheel setup.
Fitment varies across the covered sub-models, so the exact configuration matters before any tire decision is made. Single-rear-wheel trucks share the same two size paths, while dual-rear-wheel versions move to a different radial size on a different wheel diameter.

2014 RAM Trucks 3500 Laramie Longhorn 4x2
The 4x2 single-rear-wheel truck uses either 275/70R18 or 285/60R20, both in radial construction. Tire selection starts with confirming which wheel diameter is on the truck, then comparing the available tread and sidewall style within that exact size.
The 4x2 dually uses 235/80R17 radial tires, separating it clearly from the single-rear-wheel versions. That makes DRW identification essential, especially before comparing wheel fitment, load-related specifications, and available all-terrain product choices.
The 4x4 single-rear-wheel truck follows the same primary fitment pattern as the 4x2, using either 275/70R18 or 285/60R20 radial tires. The practical question is not construction type, but which wheel package the truck has and which tire style best matches its use.
The 4x4 dually uses the 235/80R17 radial size rather than the larger SRW wheel packages. Buyers should confirm the truck remains on its correct 17-inch DRW wheel setup before moving on to product comparisons or replacement planning.
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.

Owners of a 2014 RAM Trucks 3500 Laramie Longhorn usually need to sort out SRW versus DRW fitment first, then compare wheel diameter, tire size, and available radial options. The questions below focus on exact size application, product selection, appearance, and road-use checks.
Tire Size & Fitment
What tire size fits a 2014 RAM Trucks 3500 Laramie Longhorn?
The 2014 RAM Trucks 3500 Laramie Longhorn uses 275/70R18, 285/60R20, or 235/80R17 depending on the configuration. Single-rear-wheel 4x2 and 4x4 models use either 275/70R18 or 285/60R20, while dual-rear-wheel 4x2 and 4x4 models use 235/80R17.
The most important step is identifying whether the truck is SRW or DRW and then confirming the wheel diameter actually installed. A truck that has had wheel changes, trim swaps, or aftermarket upgrades may no longer match its original setup, so checking the current wheel and tire combination before replacement helps avoid the wrong size path.
What size rim does a 2014 RAM Trucks 3500 Laramie Longhorn use?
This model uses three rim diameters depending on configuration: 18-inch, 20-inch, and 17-inch. The 275/70R18 tire fits an 18-inch wheel, the 285/60R20 fits a 20-inch wheel, and the 235/80R17 fits a 17-inch wheel on dual-rear-wheel versions.
Wheel diameter should be verified before comparing tires because the same model name covers more than one wheel package. On a heavy-duty truck, it is also wise to check wheel width and overall wheel condition, especially if the truck has seen towing, off-road use, or aftermarket wheel changes that may affect the correct tire choice.
Do all 2014 RAM Trucks 3500 Laramie Longhorn sub-models use the same tire size?
No. The 2014 RAM Trucks 3500 Laramie Longhorn does not use one tire size across every covered sub-model. SRW 4x2 and 4x4 trucks use 275/70R18 or 285/60R20, while DRW 4x2 and 4x4 trucks use 235/80R17.
That difference matters because it changes both tire size and wheel diameter, not just tread choice. A dually setup brings its own wheel arrangement, so buyers should confirm the exact sub-model and current wheel hardware before ordering replacements, especially on used trucks that may have had wheel, suspension, or axle-related changes during their service life.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 RAM Trucks 3500 Laramie Longhorn?
Start with the exact size that matches the truck's configuration and wheel diameter: 275/70R18, 285/60R20, or 235/80R17. From there, compare construction, rim-width compatibility, load capacity, sidewall style, and the kind of use the truck sees, whether that is highway driving, towing, or mixed on-road and off-road service.
A one-ton truck places more importance on matching the tire to the wheel and duty cycle than on appearance alone. It helps to confirm the current wheel setup, check that the tire's specifications suit the vehicle's intended use, and make sure any replacement maintains proper clearance and an appropriate fit for the truck's actual configuration.
What sidewall styles are available for 2014 RAM Trucks 3500 Laramie Longhorn tires?
The available sidewall styles include RWL and RBL, depending on tire size. The 275/70R18 BFGoodrich All-Terrain T/A KO2 uses raised white letter styling, while the 235/80R17 KO2 uses a black sidewall presentation.
Sidewall style affects the truck's appearance more than its fitment, but it can still matter on a trim level like the Laramie Longhorn. Raised white letters create a more assertive period-inspired truck look, while a black sidewall is more restrained. Once the correct size is confirmed, sidewall preference becomes a useful way to narrow the final choice.
What brands offer tires for the 2014 RAM Trucks 3500 Laramie Longhorn?
The current product selection for the supported sizes includes BFGoodrich. The available tires shown for this model are from the All-Terrain T/A KO2 family in radial construction, with size-specific load, wheel, and sidewall details.
Brand choice only matters after the truck's exact size and wheel setup have been confirmed. Once that is settled, the useful comparison points are the tire series, sidewall presentation, and size-specific operating characteristics rather than the badge alone, especially on a heavy-duty truck that may be used for towing, hauling, or mixed-surface driving.
Restoration & Appearance
Which tire should I choose for a period-style 2014 RAM Trucks 3500 Laramie Longhorn?
A period-style choice starts with keeping the truck in its correct original size path for its actual configuration, whether that means 275/70R18, 285/60R20, or 235/80R17. On this model, the visible character comes more from wheel-and-tire proportion and sidewall treatment than from vintage construction differences, since the primary fitments are radial.
A raised white letter option can give an all-terrain SRW truck a stronger visual presence, while a black sidewall keeps the look more understated. Buyers focused on exact delivery-era appearance should also compare their truck's current wheel package against original vehicle documentation and owner history before settling on a final replacement.
Does correct tire fitment matter for a 2014 RAM Trucks 3500 Laramie Longhorn restoration?
Yes. Correct tire fitment matters because this model spans multiple wheel diameters and both SRW and DRW layouts. Using the proper size preserves the truck's stance, keeps the wheel-and-tire relationship in proportion, and avoids introducing an appearance that looks out of place for the specific configuration.
Fitment accuracy also affects practical details such as clearance and wheel compatibility, which are just as important on a restoration-minded truck as visual authenticity. Before replacing tires on a project vehicle, it is smart to confirm whether the truck still carries the wheel package and rear-wheel arrangement that belong with its sub-model.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 RAM Trucks 3500 Laramie Longhorn?
Yes. Wheel swaps, suspension changes, lifts, leveling kits, and other modifications can all affect tire fitment on a 2014 RAM Trucks 3500 Laramie Longhorn. That matters even more here because the truck already has more than one factory size path depending on wheel diameter and SRW versus DRW configuration.
A modified truck should be checked for actual wheel diameter, wheel width, and clearance at the fenders and steering components before replacement tires are chosen. On DRW models, rear-wheel spacing and hardware also deserve attention. Confirming the real setup on the truck is more useful than relying on trim name alone.
What should I inspect before driving a 2014 RAM Trucks 3500 Laramie Longhorn on new tires?
Before road use, inspect tire pressure, wheel lug torque, valve stems, tread and sidewall condition, and visible clearance around suspension and body components. On a truck like the 2014 RAM Trucks 3500 Laramie Longhorn, it also makes sense to check that all tires match the intended size and load-related specifications for the vehicle's configuration.
A short test drive followed by a second inspection can reveal rubbing, vibration, or air-loss issues early. Heavy-duty pickups often work harder than passenger vehicles, so it is wise to look over the wheels, brake components, and steering hardware at the same time, especially if the truck tows, hauls, or has been stored for long periods.
How often should tires on a 2014 RAM Trucks 3500 Laramie Longhorn be inspected?
Tires on a 2014 RAM Trucks 3500 Laramie Longhorn should be inspected regularly, not just at replacement time. Frequent visual checks for uneven wear, cuts, bulges, cracking, punctures, and pressure loss are especially important on a heavy-duty truck that may see towing, hauling, long idle periods, or mixed-surface use.
Inspection intervals should become even shorter before longer trips or after the truck has been parked for extended periods. Looking at the inside sidewalls and tread, not only the visible outer surface, helps catch problems early. Any sign of abnormal wear or repeated pressure loss should prompt a closer wheel, alignment, and suspension check.
