The 2019 RAM Trucks 2500 sits in the heavy-duty pickup segment where tire choice affects not just appearance, but how the truck carries itself on pavement, gravel, and jobsite surfaces. This generation brought a more modern HD personality, so matching the truck to the right wheel and tire package matters more than treating every 2500 the same. Tire fitment spans four primary radial sizes: 245/70R17, 285/70R17, 275/70R18, and 285/60R20, with size differences tied to sub-model and wheel setup. Available choices center on BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. The key is confirming the exact trim and rim diameter before choosing a tire for work use, all-terrain driving, or a more stock-appearing replacement.
Which Tire Size Is Right for The 2019 RAM Trucks 2500
The 2019 RAM Trucks 2500 uses four primary tire sizes, and the right one depends first on the exact sub-model and wheel diameter. Fitment spans 17-inch, 18-inch, and 20-inch rims, so confirming the truck's current wheel setup is more important than comparing tire choices by appearance alone. Once the correct size is identified, the decision shifts to load-related specifications, intended use, and whether the tire matches the truck's work, highway, or all-terrain role.
Fit(s): Big Horn, Laramie, Laramie Longhorn, Lone Star, and Tradesman
Construction: Radial|Rim: 18 in
275/70R18 is a metric radial size in which 275 identifies nominal section width in millimeters, 70 is the aspect ratio, R designates radial construction, and 18 is the wheel diameter in inches. On the 2019 RAM Trucks 2500, this size is part of the truck's modern heavy-duty fitment range and is used on certain sub-models equipped with 18-inch wheels. Available options in this size include BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. This size is worth considering when the truck already wears 18-inch rims and the goal is to stay with the proper wheel diameter and a truck-oriented radial tire.
Fit(s): Big Horn, Laramie, Laramie Longhorn, Limited, and Lone Star
Construction: Radial|Rim: 20 in
285/60R20 is a metric radial size with a 285-millimeter nominal section width, a 60-series profile, radial construction, and a 20-inch rim diameter. For the 2019 RAM Trucks 2500, this size belongs to trims that use a larger wheel package, so it should be chosen only when the truck is actually equipped with 20-inch wheels. Its lower-profile format gives it a different fitment context than the 17-inch and 18-inch sizes used elsewhere in the lineup. This is the size to evaluate when trim level and wheel diameter both point to the factory-style 20-inch setup rather than a smaller heavy-duty wheel package.
285/70R17 is a metric radial size where 285 is the nominal width in millimeters, 70 is the aspect ratio, R marks radial construction, and 17 identifies the rim diameter. On the 2019 RAM Trucks 2500, this size is tied to the Power Wagon and sits apart from the other fitments because it combines a 17-inch wheel with a wider, taller all-terrain-style footprint. BFGoodrich All-Terrain T/A KO2 options are available in this size with raised white letter sidewalls and differing load-related specifications. This size should be evaluated with the truck's exact wheel package and intended off-pavement or heavy-duty use in mind.
245/70R17 is a metric radial size that uses a 245-millimeter nominal section width, a 70-series profile, radial construction, and a 17-inch wheel diameter. For the 2019 RAM Trucks 2500, this size appears on certain Tradesman configurations and represents a different fitment path than the wider 17-inch option used on the Power Wagon. BFGoodrich All-Terrain T/A KO2 is available in this size with a raised white letter sidewall and truck-duty specifications. This size makes sense only after confirming that the truck is one of the 17-inch Tradesman setups rather than an 18-inch or 20-inch wheel configuration.
Sub-model fitment on the 2019 RAM Trucks 2500 is not one-size-fits-all, because tire size changes with trim and wheel package. Checking the exact sub-model is the quickest way to narrow the correct rim diameter and avoid choosing between 17-inch, 18-inch, and 20-inch tires by mistake.

2019 RAM Trucks 2500 Big Horn
The 2019 RAM Trucks 2500 Big Horn uses either 275/70R18 or 285/60R20, both in radial construction. Tire selection starts with confirming whether the truck has the 18-inch or 20-inch wheel setup, then comparing the available product's load-related specs and intended use.
The 2019 RAM Trucks 2500 Laramie also falls into the two-size group, using either 275/70R18 or 285/60R20 radial tires. That makes wheel confirmation especially important before ordering, since the right choice depends on the truck's actual rim diameter rather than trim name alone.
The 2019 RAM Trucks 2500 Laramie Longhorn uses the same two radial fitment paths as several other trims: 275/70R18 or 285/60R20. The practical decision is determining which wheel package is on the truck now, especially if it has seen wheel or tire changes since new.
The 2019 RAM Trucks 2500 Limited uses 285/60R20 radial tires. Since this trim stays with one primary size, the buyer's focus shifts from size selection to confirming the 20-inch wheel setup and choosing a tire that matches the truck's load and use expectations.
The 2019 RAM Trucks 2500 Lone Star uses either 275/70R18 or 285/60R20 in radial construction. Choosing correctly means verifying the wheel diameter on the truck first, then selecting within the proper size instead of assuming every Lone Star uses the same tire.
The 2019 RAM Trucks 2500 Power Wagon uses 285/70R17 radial tires. That keeps tire selection more straightforward, but it still helps to compare the available load-related versions in this size and confirm the truck remains on its 17-inch wheel setup.
The 2019 RAM Trucks 2500 Tradesman uses either 245/70R17 or 275/70R18, both as radial fitments. The important step is checking whether the truck carries the 17-inch or 18-inch wheel package before comparing tire options, especially on work trucks that may have had replacements over time.
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.
Best 2019 RAM Trucks 2500 Tires for Sale
Available 2019 RAM Trucks 2500 tire choices center on BFGoodrich All-Terrain T/A KO2 fitments in 245/70R17, 275/70R18, and 285/70R17. The main comparison points are rim-width compatibility, load-at-pressure ratings, weight, and the consistent raised white letter sidewall presentation.
Common 2019 RAM Trucks 2500 tire questions usually come down to identifying the correct trim and wheel diameter, then sorting through radial size differences, product specifications, sidewall presentation, and the condition checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2019 RAM Trucks 2500?
The 2019 RAM Trucks 2500 uses four primary tire sizes: 245/70R17, 285/70R17, 275/70R18, and 285/60R20. All four are radial fitments, but they do not apply universally across the lineup because different sub-models and wheel packages use different sizes.
The practical first step is identifying the exact trim and then confirming the truck's current wheel diameter. A Tradesman, Power Wagon, Big Horn, or Limited can point you toward a different size path, and aftermarket wheels can complicate matters further if the truck no longer carries its original-style rim setup.
What size rim does a 2019 RAM Trucks 2500 use?
A 2019 RAM Trucks 2500 can use 17-inch, 18-inch, or 20-inch rims, depending on sub-model and tire size. The 245/70R17 and 285/70R17 sizes use 17-inch rims, 275/70R18 uses an 18-inch rim, and 285/60R20 uses a 20-inch rim.
Rim diameter should be verified before anything else, because the tire size must match it exactly. Once that is confirmed, it also helps to check wheel width, especially on trucks that have seen wheel changes, since the available tires carry their own rim-width compatibility ranges that affect proper mounting.
Why does the 2019 RAM Trucks 2500 have more than one tire size?
The 2019 RAM Trucks 2500 has more than one tire size because the model range includes several trims with different wheel packages. Some use 17-inch wheels, some use 18-inch wheels, and others use 20-inch wheels, which leads to four separate primary radial tire sizes across the lineup.
That means tire selection should start with the truck's exact configuration rather than the 2500 name alone. Looking at the sidewall size on the current tire and confirming the wheel diameter on the truck are both worthwhile, especially when the truck has had replacement wheels, trim swaps, or work-use changes over time.
Choosing the Right Tire
What should I consider when choosing a 2019 RAM Trucks 2500 tire?
Start with the correct tire size for the exact sub-model and wheel diameter, since the 2019 RAM Trucks 2500 uses four different radial fitments. After size is settled, compare the tire's load-at-pressure rating, rim-width range, and overall role, especially if the truck is used for towing, work duty, or mixed pavement and gravel driving.
Appearance can matter too, but it should come after fitment basics. A raised white letter all-terrain tire may suit some builds well, while another owner may care more about maintaining the truck's intended wheel package and staying within the proper mounting range for the wheel already on the vehicle.
What sidewall styles are available for 2019 RAM Trucks 2500 tires?
The available 2019 RAM Trucks 2500 products here use an RWL sidewall, which means raised white letter styling. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options offered in the applicable sizes, giving the truck a more traditional off-road and truck-performance look.
Sidewall style affects presentation more than fitment, so it should be chosen after the correct size and wheel diameter are confirmed. Owners who want the tire to complement a more rugged build may appreciate raised white letters, while those focused on a subtler look may want to consider how the lettering orientation affects the truck's finished appearance.
What tire series are available for the 2019 RAM Trucks 2500?
The available tire series for the 2019 RAM Trucks 2500 is BFGoodrich All-Terrain T/A KO2. It appears in the supported product range for 245/70R17, 275/70R18, and 285/70R17, making it the main series to compare when staying within the sizes offered here.
Since the series is consistent, the more useful comparison comes from size-specific details such as load-at-pressure rating, rim-width compatibility, and tire weight. Those factors matter more on a heavy-duty truck than series name alone, particularly when the truck is used for hauling, uneven surfaces, or longer highway miles.
Restoration & Appearance
Which tire should I choose for a period-style 2019 RAM Trucks 2500?
A period-style choice for a 2019 RAM Trucks 2500 begins with staying in the truck's correct original-type size path for its trim and wheel diameter. Because this is a modern heavy-duty pickup, the visual character comes more from preserving the right wheel-and-tire proportion than from chasing vintage-style construction changes.
The available BFGoodrich All-Terrain T/A KO2 options suit an assertive truck presentation, especially with raised white letters. Owners aiming for a stock-leaning appearance should confirm the truck's sub-model, current wheel package, and sidewall look before choosing, rather than assuming any one size or style suits every 2500 build.
How does tire construction affect the appearance of a restored 2019 RAM Trucks 2500?
On a 2019 RAM Trucks 2500, appearance differences come less from bias-ply versus radial construction and more from tire size, sidewall treatment, and wheel diameter, since the primary fitments are all radial. A 17-inch, 18-inch, or 20-inch package changes the truck's stance and visual balance more noticeably than construction type alone.
Raised white letter sidewalls can also push the truck toward a more off-road-oriented look. For an owner freshening a clean, original-style truck, preserving the correct trim-specific size and wheel relationship usually matters most, while modified trucks may place more emphasis on visual stance and tire profile.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 RAM Trucks 2500?
Yes, modifications can affect tire fitment on a 2019 RAM Trucks 2500 even when the tire size seems close. Aftermarket wheels, different wheel widths, suspension lifts, leveling kits, or body changes can alter clearance and may also change whether the truck still matches its original trim-based size path.
Checking the current wheel diameter and width is the smart starting point before replacing tires on a modified truck. It also helps to inspect steering clearance, fender space, and suspension travel, since a size that belongs on one 2500 configuration should not be assumed to work the same way on another altered setup.
What should I inspect before driving a 2019 RAM Trucks 2500 on new tires?
Before driving a 2019 RAM Trucks 2500 on new tires, inspect wheel condition, valve stems, lug hardware, and inflation pressure, then confirm the tire size matches the truck's wheel diameter and trim. It is also wise to look over suspension and steering components so the new tires are not immediately affected by worn parts.
A quick clearance check at full steering lock can help catch problems early, especially on trucks with wider tires or changed ride height. After the first miles, recheck air pressure and look for any signs of rubbing, uneven wear, or vibration so small setup issues do not turn into bigger tire problems.
How should tires on a 2019 RAM Trucks 2500 be maintained?
Tires on a 2019 RAM Trucks 2500 should be maintained with regular pressure checks, visual inspections, and attention to tread wear across the full width of the tire. Heavy-duty trucks can place extra demand on tires, so catching underinflation, cuts, sidewall damage, or uneven wear early is especially important.
Maintenance should also include watching for slow air loss and checking alignment-related wear if the truck begins to pull or the tread pattern changes. Owners who use the truck intermittently should not ignore age and storage conditions, because even a low-mile tire can become questionable when time, heat, and inactivity take their toll.
