The 2025 RAM Trucks 2500 sits squarely in the heavy-duty pickup world, where towing strength, payload capability, and trim-specific equipment all shape the truck’s stance and tire needs. On this model, tire fitment is not one-size-fits-all: depending on sub-model, the truck uses 245/70R17, 285/70R17, 275/70R18, or 285/60R20 radial tires. That makes wheel diameter and exact trim identification the first step before comparing options. Available selections center on BFGoodrich All-Terrain T/A KO2 products with raised white letter sidewalls in the supported sizes. For owners balancing work use, off-pavement traction, or a stock-appearance replacement, getting the exact size right comes before any other tire decision.
Which Tire Size Is Right for The 2025 RAM Trucks 2500
The 2025 RAM Trucks 2500 uses four primary tire sizes, and they vary by sub-model and wheel diameter. Some trims run 17-inch wheels, others use 18-inch or 20-inch wheels, so the first step is confirming the exact sub-model and the wheel size currently on the truck. Once that is settled, the decision shifts to selecting the right radial tire within that size and matching it to the truck’s intended use.
Fit(s): Big Horn, Laramie, Tradesman, and Tradesman w/Chrome Pkg.
Construction: Radial|Rim: 18 in
In 275/70R18, the 275 is the nominal section width in millimeters, the 70 is the aspect ratio, the R identifies radial construction, and the 18 is the wheel diameter in inches. This is a modern radial fitment used on certain 2025 RAM Trucks 2500 sub-models with 18-inch wheels. Available choices in this size include a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. It is the size to focus on when the truck already has the correct 18-inch wheel setup and the goal is to stay with the intended overall fitment category.
Fit(s): Big Horn w/Night Edition, Laramie w/Sport/Night Pkg., Limited, Limited Longhorn, and Rebel
Construction: Radial|Rim: 20 in
In 285/60R20, the 285 is the nominal tire width in millimeters, the 60 is the aspect ratio, the R marks radial construction, and the 20 identifies a 20-inch rim. This size belongs to specific 2025 RAM Trucks 2500 trims equipped with 20-inch wheels, so it should not be treated as interchangeable with the 17-inch or 18-inch fitments. Its shorter sidewall profile relative to the other listed sizes is part of the trim-specific setup. Choosing this size starts with verifying that the truck is one of the 20-inch wheel configurations rather than a different package or wheel swap.
In 285/70R17, the 285 is the nominal section width in millimeters, the 70 is the aspect ratio, the R means radial, and the 17 indicates a 17-inch wheel. This size is used on the 2025 RAM Trucks 2500 Power Wagon and carries a taller sidewall on a 17-inch rim than the 20-inch fitment. BFGoodrich All-Terrain T/A KO2 options are available in this size with raised white letter sidewalls, including versions with different load and pressure figures. It is the right place to compare products when the truck is a Power Wagon or already verified to use this exact 17-inch wheel and tire package.
In 245/70R17, the 245 is the nominal width in millimeters, the 70 is the aspect ratio, the R identifies radial construction, and the 17 is the wheel diameter in inches. This is another 17-inch fitment, but it is narrower and shorter overall than the 285/70R17 option, so it serves a different role within the 2025 RAM Trucks 2500 range. A BFGoodrich All-Terrain T/A KO2 is available in this size with raised white letter sidewalls. It should be selected only after confirming the truck’s exact Tradesman configuration and making sure the wheel width matches the tire’s supported range.
Tire fitment on the 2025 RAM Trucks 2500 depends heavily on trim and package, with four different primary sizes spread across 17-inch, 18-inch, and 20-inch wheel setups. Checking the exact sub-model matters because the correct tire choice starts with the wheel diameter and trim-specific fitment rather than appearance alone.

2025 RAM Trucks 2500 Big Horn
The 2025 RAM Trucks 2500 Big Horn uses the 275/70R18 radial size. Tire selection here is mainly about staying with the proper 18-inch fitment and then comparing the available product style and specification details within that size.
The 2025 RAM Trucks 2500 Big Horn w/Night Edition uses the 285/60R20 radial size. That makes wheel confirmation especially important, since this trim-specific 20-inch fitment is different from the 17-inch and 18-inch setups used elsewhere in the 2500 lineup.
The 2025 RAM Trucks 2500 Laramie uses the 275/70R18 radial size. For this sub-model, the main task is choosing an 18-inch tire that matches the truck’s current wheel setup and intended use without drifting into another trim’s tire dimensions.
The 2025 RAM Trucks 2500 Laramie w/Sport/Night Pkg. uses the 285/60R20 radial size. Tire selection should begin by confirming that the truck still carries its 20-inch wheel package, since that size is specific to this configuration and not shared with every Laramie.
The 2025 RAM Trucks 2500 Limited uses the 285/60R20 radial size. That points the buyer toward the 20-inch fitment path first, with the practical focus on matching the existing wheel diameter before comparing tire choices.
The 2025 RAM Trucks 2500 Limited Longhorn uses the 285/60R20 radial size. The important fitment step is verifying the 20-inch wheel setup, then selecting a tire that stays within the intended size category for this sub-model.
The 2025 RAM Trucks 2500 Power Wagon uses the 285/70R17 radial size. That gives this sub-model its own 17-inch fitment path, so tire selection centers on the correct wheel diameter and the available product specifications within that size.
The 2025 RAM Trucks 2500 Rebel uses the 285/60R20 radial size. Choosing tires for this configuration starts with keeping the 20-inch wheel and tire relationship in view rather than assuming a different 2500 trim uses the same dimensions.
The 2025 RAM Trucks 2500 Tradesman is the one sub-model here with two primary tire-size paths: 245/70R17 or 275/70R18, both radial. Selecting the right tire means confirming which wheel package the truck actually has before comparing product details or considering any alternate setup.
The 2025 RAM Trucks 2500 Tradesman w/Chrome Pkg. uses the 275/70R18 radial size. That keeps the decision straightforward once the package is confirmed, with attention shifting to the proper 18-inch tire and the available product characteristics in that 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.
Best 2025 RAM Trucks 2500 Tires for Sale
Available tire choices for the 2025 RAM Trucks 2500 center on BFGoodrich All-Terrain T/A KO2 radial products in supported 17-inch and 18-inch sizes. Across these options, the main comparison points are size, load-and-pressure specification, rim-width compatibility, and raised white letter sidewall presentation.
Owners of a 2025 RAM Trucks 2500 usually need to sort out trim-specific tire size first, then compare wheel diameter, radial tire options, sidewall style, and practical fitment checks before putting the truck back into regular road or work use.
Tire Size & Fitment
What tire size fits a 2025 RAM Trucks 2500?
The 2025 RAM Trucks 2500 uses four primary tire sizes: 245/70R17, 285/70R17, 275/70R18, and 285/60R20. All of them are radial sizes, and the correct one depends on the truck’s exact sub-model and wheel package rather than the model name alone.
The most important next step is confirming the trim and the wheel diameter currently on the truck. A Tradesman can use either a 17-inch or 18-inch setup, while other trims are tied to one size path, so checking the tire sidewall and wheel before ordering avoids choosing the wrong fitment category.
What size rim does a 2025 RAM Trucks 2500 use?
A 2025 RAM Trucks 2500 can use 17-inch, 18-inch, or 20-inch rims depending on sub-model. The 245/70R17 and 285/70R17 sizes mount on 17-inch wheels, 275/70R18 uses an 18-inch wheel, and 285/60R20 uses a 20-inch wheel.
Rim diameter needs to match the tire size exactly, so this is the first fitment check on any 2500. After that, wheel width still matters, especially on trucks with aftermarket wheels, because a tire can have the right diameter but still fall outside the wheel’s supported width range.
Why does the 2025 RAM Trucks 2500 have more than one tire size?
The 2025 RAM Trucks 2500 has more than one tire size because its trim levels and packages use different wheel-and-tire combinations. Big Horn, Laramie, Limited, Power Wagon, Rebel, and Tradesman configurations do not all share the same wheel diameter or tire dimensions.
That means tire selection starts with the truck’s exact configuration, not just the year, make, and model. Package differences such as 17-inch, 18-inch, or 20-inch wheels change the correct tire size immediately, and any truck that has already been modified should be checked against the wheel and tire actually installed.
Choosing the Right Tire
What should I consider when choosing a 2025 RAM Trucks 2500 tire?
Start with the exact tire size and wheel diameter used by the truck’s sub-model. On a 2025 RAM Trucks 2500, that means choosing among 245/70R17, 285/70R17, 275/70R18, or 285/60R20, then staying with the correct radial construction and checking the wheel width the tire is designed to support.
After size is settled, compare how the truck will be used. Load-and-pressure figures, tire weight, and the overall character of an all-terrain design matter on a heavy-duty pickup, especially if it sees towing, jobsite use, or regular highway miles instead of occasional light-duty driving.
What sidewall styles are available for 2025 RAM Trucks 2500 tires?
The supported products available here for the 2025 RAM Trucks 2500 use an RWL sidewall, meaning raised white letters. That styling appears on the BFGoodrich All-Terrain T/A KO2 options offered in the applicable 17-inch and 18-inch sizes.
Sidewall style affects the truck’s presentation more than its base fitment, but it still matters to many owners. A raised white letter sidewall gives the tire a more traditional all-terrain look, so the practical decision becomes matching that appearance with the correct size, wheel setup, and load-oriented product specification.
What brands offer tires for the 2025 RAM Trucks 2500?
The available products here for the 2025 RAM Trucks 2500 come from BFGoodrich. The offered tires are from the All-Terrain T/A KO2 line in the supported 245/70R17, 275/70R18, and 285/70R17 fitments.
Brand choice is only part of the decision on this truck because the correct size still depends on trim and wheel diameter first. Once that is verified, compare the available BFGoodrich options by size, rim-width specification, load-and-pressure figure, and whether the truck’s use leans more toward work duty, highway driving, or mixed terrain.
Restoration & Appearance
Which tire should I choose for a period-style 2025 RAM Trucks 2500?
A period-style approach on a 2025 RAM Trucks 2500 still starts with the exact original fitment category for the truck’s trim, whether that is 245/70R17, 285/70R17, 275/70R18, or 285/60R20. Because this is a current heavy-duty pickup, the appearance decision is usually less about vintage authenticity and more about staying true to the truck’s factory-era stance.
Keeping the correct wheel diameter and overall tire profile for the sub-model preserves the truck’s intended visual balance better than mixing trim-specific sizes. An all-terrain radial with raised white letters can also shape the truck’s look, but appearance should always be considered after confirming the proper fitment path.
How does tire construction affect the appearance of a restored 2025 RAM Trucks 2500?
Tire construction is straightforward on the 2025 RAM Trucks 2500 because the primary fitments here are all radial. That means appearance differences are shaped more by tire size, sidewall height, wheel diameter, and sidewall treatment than by a bias-ply-versus-radial decision.
A 17-inch all-terrain setup presents differently from an 18-inch or 20-inch package even when all are radials, so matching the trim-specific size matters visually. Owners aiming for a stock-era look should preserve the truck’s correct wheel-and-tire relationship first, then refine the final presentation through the available sidewall style and tire line.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 RAM Trucks 2500?
Yes, modifications can affect tire fitment on a 2025 RAM Trucks 2500 even when the tire size is correct for the original sub-model. Aftermarket wheels, altered wheel width, suspension changes, ride-height adjustments, and body modifications can all change how a 17-inch, 18-inch, or 20-inch tire sits on the truck.
That is especially important on a model with several factory size paths already in play. A tire that matches the trim on paper still needs to be checked against the wheel actually installed, along with steering clearance, fender clearance, and suspension travel before assuming the setup remains appropriate.
What should I inspect before driving a 2025 RAM Trucks 2500 on new tires?
Before putting a 2025 RAM Trucks 2500 into service on new tires, inspect wheel condition, confirm the tire size matches the truck’s trim and rim diameter, and verify inflation is appropriate for the installed tire. It is also wise to look for uneven suspension wear, alignment issues, and any interference at full steering lock.
A heavy-duty truck places real demands on its tires, so a quick visual check is not enough. Look over the tread and sidewalls after installation, recheck air pressure once the tires have settled, and make sure there is no rubbing under load or while turning before heading into regular work or highway use.
How often should tires on a 2025 RAM Trucks 2500 be inspected?
Tires on a 2025 RAM Trucks 2500 should be inspected regularly, especially before towing, hauling, or longer highway drives. Frequent checks for air loss, cuts, punctures, uneven wear, sidewall damage, and tread condition are important because this truck’s tire loads can be substantial in everyday use.
A practical routine is to inspect the tires visually and check pressure before major trips, then look more closely any time the truck begins to pull, vibrate, or wear tires unevenly. Trucks that spend time off pavement or on rough worksites deserve even closer attention because wheel damage and sidewall injuries are easier to miss.
