The 2014 RAM Trucks 3500 Lone Star sits in the heavy-duty end of the modern pickup market, where towing, payload, and long-wheelbase road manners matter just as much as trim and appearance. For buyers replacing tires on this exact truck, the first step is identifying the wheel and axle configuration, because this model uses more than one primary radial tire size. Single-rear-wheel trucks use either 275/70R18 or 285/60R20, while dually versions use 235/80R17. Available choices here lean toward an all-terrain radial approach, so the real decision is matching the correct size to the truck's specific setup and intended use before comparing sidewall presentation and wheel compatibility.
Which Tire Size Is Right for The 2014 RAM Trucks 3500 Lone Star
The 2014 RAM Trucks 3500 Lone Star uses three primary tire sizes, and the right one depends on the truck's exact sub-model and wheel diameter. All three are radial fitments, but they do not share the same rim size. Before choosing a tire, confirm whether the truck is single-rear-wheel or dually and verify whether it is equipped with 17-inch, 18-inch, or 20-inch wheels.
275/70R18 is a metric radial size in which 275 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2014 RAM Trucks 3500 Lone Star, this size is used on single-rear-wheel configurations rather than dually trucks. In this fitment, the available product is a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. This size makes the most sense when the truck already carries 18-inch wheels and you want to stay with the correct primary fitment for that setup.
285/60R20 is a metric radial size that combines a 285-millimeter nominal section width, a 60-series profile, and a 20-inch wheel diameter. On the 2014 RAM Trucks 3500 Lone Star, it applies to certain single-rear-wheel 4x2 and 4x4 trucks equipped with 20-inch wheels. Its role in this application is different from the 17-inch dually fitment and the 18-inch single-rear-wheel fitment, so wheel confirmation matters before purchase. This is the size to evaluate when the truck is already set up around a 20-inch package and you need to preserve that rim diameter.
235/80R17 is a metric radial size with a 235-millimeter nominal section width, an 80-series profile, and a 17-inch rim diameter. On the 2014 RAM Trucks 3500 Lone Star, this size is tied to dual-rear-wheel configurations, making it a distinct fitment from the single-rear-wheel 18-inch and 20-inch options. The available product is a BFGoodrich All-Terrain T/A KO2 with black sidewall styling. This size should be considered when the truck is a dually and still uses the correct 17-inch wheel setup for that application.
Sub-model fitment matters on the 2014 RAM Trucks 3500 Lone Star because tire size changes with both wheel package and rear-wheel configuration. Single-rear-wheel trucks share the 18-inch and 20-inch options, while dually versions move to a separate 17-inch fitment.

2014 RAM Trucks 3500 Lone Star 4x2
The 2014 RAM Trucks 3500 Lone Star 4x2 uses either 275/70R18 or 285/60R20, both in radial construction. Tire selection starts with confirming which wheel diameter is on the truck now, then comparing tires within that exact size rather than treating the two fitments as interchangeable.
The 2014 RAM Trucks 3500 Lone Star 4x2 (DRW) uses the 235/80R17 radial size. That makes this sub-model a different fitment path from the single-rear-wheel truck, so dually owners should stay focused on the correct 17-inch size and wheel setup before comparing tire options.
The 2014 RAM Trucks 3500 Lone Star 4x4 uses either 275/70R18 or 285/60R20 in radial construction. The practical decision is confirming whether the truck has the 18-inch or 20-inch wheel package, then choosing within that size based on intended use and tire characteristics.
The 2014 RAM Trucks 3500 Lone Star 4x4 (DRW) uses the 235/80R17 radial fitment. For this sub-model, the key is matching the dually's 17-inch wheel setup and load-oriented application instead of comparing it to the single-rear-wheel 18-inch and 20-inch sizes.
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.

For the 2014 RAM Trucks 3500 Lone Star, the most important questions center on matching the correct tire size to the truck's wheel and rear-wheel configuration, then comparing radial tire options, sidewall styles, and basic road-use checks.
Tire Size & Fitment
What tire size fits a 2014 RAM Trucks 3500 Lone Star?
The 2014 RAM Trucks 3500 Lone Star uses three primary tire sizes: 275/70R18, 285/60R20, and 235/80R17. Single-rear-wheel 4x2 and 4x4 trucks use either 275/70R18 or 285/60R20, while dual-rear-wheel versions use 235/80R17.
The correct choice depends on the truck's exact sub-model and wheel setup, not just the model name on the badge. Checking whether the truck is SRW or DRW and confirming the wheel diameter already on the vehicle will narrow the fitment quickly and prevent ordering a tire built for a different configuration.
What size rim does a 2014 RAM Trucks 3500 Lone Star use?
A 2014 RAM Trucks 3500 Lone Star may use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model and tire size. The 235/80R17 fitment uses a 17-inch rim, 275/70R18 uses an 18-inch rim, and 285/60R20 uses a 20-inch rim.
Rim diameter is the first fitment detail to verify because these sizes are not interchangeable across different wheel diameters. A quick check of the current tire sidewall or the wheel itself usually confirms the setup, and that should be matched before comparing tread style, sidewall appearance, or other product differences.
Why does the 2014 RAM Trucks 3500 Lone Star have more than one tire size?
More than one tire size appears on the 2014 RAM Trucks 3500 Lone Star because the truck was offered in different wheel packages and in both single-rear-wheel and dual-rear-wheel configurations. That creates separate primary fitments rather than one universal size for every version.
The practical takeaway is that the truck's exact configuration matters more than broad year-make-model identification. Owners should verify wheel diameter, count the rear wheels on each side, and confirm whether the truck is 4x2 or 4x4 before selecting a tire, especially if the truck has been modified or fitted with aftermarket wheels.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 RAM Trucks 3500 Lone Star?
Start with the correct primary size for the truck: 275/70R18, 285/60R20, or 235/80R17. From there, compare radial construction details that matter to a heavy-duty pickup, including rim-width compatibility, maximum load at the stated pressure, sidewall style, and whether the tire's overall character suits the way the truck is used.
A single-rear-wheel truck and a dually do not ask the same things from a tire, even when both carry the 3500 Lone Star name. Matching the tire to the truck's current wheel package and intended work or road use will usually matter more than cosmetic preference alone.
What sidewall styles are available for 2014 RAM Trucks 3500 Lone Star tires?
Sidewall styling varies by size on the 2014 RAM Trucks 3500 Lone Star. The available 275/70R18 BFGoodrich All-Terrain T/A KO2 uses raised white letter sidewalls, while the available 235/80R17 KO2 uses a black sidewall presentation.
That difference matters if appearance is part of the decision, especially on a truck that balances work duty with enthusiast ownership. Sidewall style should still come after the correct size, wheel diameter, and configuration check, because a preferred look does not override the truck's required fitment.
What brands offer tires for the 2014 RAM Trucks 3500 Lone Star?
BFGoodrich is available for the 2014 RAM Trucks 3500 Lone Star in the currently covered product selection. The offerings shown here are in the All-Terrain T/A KO2 series, with size-specific differences in sidewall style, rim-width range, load capacity, and tire weight.
That means the buying decision is less about comparing multiple brands and more about matching the correct size and specification to the truck's setup. Once the wheel diameter and SRW or DRW configuration are confirmed, it becomes easier to compare the available KO2 product details in the appropriate fitment.
Restoration & Appearance
Does correct tire fitment matter for a 2014 RAM Trucks 3500 Lone Star restoration or clean-up project?
Correct tire fitment still matters, even on a newer heavy-duty truck like the 2014 RAM Trucks 3500 Lone Star. Using the proper 17-inch, 18-inch, or 20-inch size for the truck's exact configuration helps preserve the intended stance, wheel relationship, and overall presentation.
Appearance work often starts with details that look small on paper but stand out on the vehicle. A dually wearing the correct 235/80R17 setup presents differently from a single-rear-wheel truck on 275/70R18 or 285/60R20, so wheel package accuracy should be settled before focusing on sidewall style.
How does tire choice affect the appearance of a 2014 RAM Trucks 3500 Lone Star?
Tire choice influences the truck's visual character through size, wheel diameter, and sidewall treatment. On the 2014 RAM Trucks 3500 Lone Star, a raised white letter 275/70R18 creates a different look from a black sidewall 235/80R17, even though both are proper radial fitments for their respective configurations.
The best approach is to treat appearance as part of the final comparison, not the first one. Once the truck's exact SRW or DRW setup and wheel diameter are confirmed, sidewall style can help refine whether the finished truck looks more work-focused, more traditional, or more aggressively all-terrain.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 RAM Trucks 3500 Lone Star?
Yes, modifications can affect tire fitment on a 2014 RAM Trucks 3500 Lone Star. Aftermarket wheels, suspension changes, leveling kits, lift kits, and changes in wheel width or offset can all alter how a 275/70R18, 285/60R20, or 235/80R17 tire sits in the truck's wheel openings.
A truck that no longer has its original wheel setup should be checked carefully before replacement tires are chosen. Wheel diameter is only part of the picture; clearance at full steering lock, spacing around suspension components, and the relationship between tire width and rim width should also be reviewed.
What should I inspect before driving a 2014 RAM Trucks 3500 Lone Star on new tires?
Before driving on new tires, inspect inflation pressure, wheel condition, valve stems, lug torque, and visible tire condition. It also helps to confirm that all tires match the intended size for the truck's exact configuration and that there is no rubbing at the fenders, suspension, or steering components.
A heavy-duty pickup can hide fitment issues until it is loaded, turned sharply, or driven at highway speed. A short local drive followed by another visual check is a sensible way to catch clearance concerns, uneven seating, or pressure loss before the truck goes back into regular service.
How often should tires on a 2014 RAM Trucks 3500 Lone Star be inspected?
Tires on a 2014 RAM Trucks 3500 Lone Star should be inspected regularly rather than only at replacement time. Frequent pressure checks and routine visual inspections for irregular wear, cuts, cracking, bulges, and air loss are especially important on a truck that may see towing, hauling, or long highway use.
Inspection intervals should become even more attentive if the truck sits for long periods or carries changing loads. Looking over the tires before longer drives and checking that wear remains even across the tread can help reveal alignment, inflation, or wheel-fit issues before they become larger problems.
