The 2025 RAM Trucks 3500 is built for serious work, whether it is set up for towing, hauling, or heavy-duty fleet use. In this part of the truck market, tire selection is tied closely to the exact trim and wheel package, because the 3500 spans single-rear-wheel and dual-rear-wheel configurations with different rim diameters. Primary fitment centers on radial sizes 275/70R18, 235/80R17, and 285/60R20. That makes this page less about broad tire theory and more about confirming the exact sub-model first, then choosing the right construction, sidewall presentation, and load-capable product for the way the truck is actually equipped and used.
Which Tire Size Is Right for The 2025 RAM Trucks 3500
The 2025 RAM Trucks 3500 uses three primary tire sizes, and they do not all share the same rim diameter. Tire choice depends first on confirming the exact sub-model and wheel setup, especially because DRW and non-DRW versions use different sizes. Once that is established, the next step is comparing radial tire options that match the truck's intended work use, wheel dimensions, and overall appearance.
275/70R18 is a metric radial size in which 275 represents section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2025 RAM Trucks 3500, this size serves as a primary fitment for certain single-rear-wheel sub-models and keeps the truck in a modern heavy-duty radial format. Available choices include a BFGoodrich All Terrain TA KO2 with raised white letter sidewall styling. This size is worth considering when your truck is equipped with the correct 18-inch wheels and you want a tire suited to heavy-duty use without stepping outside the original fitment category.
Fit(s): Big Horn (DRW), Big Horn (DRW) w/Night Edition, Laramie (DRW), Laramie (DRW) w/Night Edition, Limited (DRW), Limited Longhorn (DRW), Tradesman (DRW), and Tradesman 4x4 (DRW)
Construction: Radial|Rim: 17 in
235/80R17 is a metric radial size with a 235-millimeter nominal width, an 80-series profile, radial construction, and a 17-inch rim requirement. On the 2025 RAM Trucks 3500, this size is tied to dual-rear-wheel configurations, making it an important fitment distinction rather than just an alternate size. BFGoodrich offers this fitment in the All Terrain TA KO2 series, here with an RBL sidewall treatment. Choosing this size starts with confirming that the truck is a DRW model and that the wheel setup remains correct for the narrower 17-inch fitment.
Fit(s): Big Horn w/Night Edition, Laramie w/Night/Sport Pkg., Limited, and Limited Longhorn
Construction: Radial|Rim: 20 in
285/60R20 is a metric radial size that uses a 285-millimeter nominal width, a 60-series profile, and a 20-inch rim diameter. On the 2025 RAM Trucks 3500, it appears on specific higher-trim or appearance-package single-rear-wheel configurations, so it should not be treated as a universal size across the model line. Its lower-profile format gives it a different fitment role than the 17-inch and 18-inch options used elsewhere in the 3500 range. This is the size to evaluate only after confirming that the truck is equipped with the correct 20-inch wheel package and matching sub-model configuration.
Sub-model fitment matters on the 2025 RAM Trucks 3500 because tire size changes across trim levels, wheel packages, and DRW versus non-DRW configurations. The first step is matching the tire to the exact sub-model, since the truck line spans 17-inch, 18-inch, and 20-inch rim fitments.

Owners of a 2025 RAM Trucks 3500 usually need to sort out exact tire size by sub-model, DRW versus non-DRW fitment, and wheel diameter before comparing products. These FAQs also cover rim fitment, sidewall presentation, tire selection, and practical inspection points before road use.
Tire Size & Fitment
What tire size fits a 2025 RAM Trucks 3500?
The 2025 RAM Trucks 3500 uses three primary radial tire sizes: 275/70R18, 235/80R17, and 285/60R20. The correct size depends on the exact sub-model and wheel package, with dual-rear-wheel versions using 235/80R17 and certain single-rear-wheel trims using either 275/70R18 or 285/60R20.
The practical step is to identify the truck's exact trim and confirm its current wheel diameter before choosing a replacement tire. A 3500 can look similar across trims while using very different rim sizes, so checking the sidewall marking on the current tire and verifying whether the truck is DRW or non-DRW helps prevent ordering the wrong fitment.
What size rim does a 2025 RAM Trucks 3500 use?
A 2025 RAM Trucks 3500 can use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model. 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 thing to verify because none of these tire sizes cross over to a different wheel size. After that, it is smart to confirm the wheel width as well, especially on trucks with aftermarket wheels or replacement rims, since a heavy-duty truck's tire choice needs to match both the wheel and the vehicle's working setup.
Do all 2025 RAM Trucks 3500 sub-models use the same tire size?
No, 2025 RAM Trucks 3500 sub-models do not all use the same tire size. Fitment varies across the range, with 275/70R18 used on some single-rear-wheel trims, 285/60R20 used on certain higher-trim or appearance-package versions, and 235/80R17 used on dual-rear-wheel configurations.
That difference matters because the correct tire is tied to both the truck's trim and its wheel hardware. A DRW truck should be treated differently from a single-rear-wheel truck, and a Night Edition or upper-trim model may carry a different rim diameter than a standard version. Confirming the exact sub-model keeps the search focused on the correct fitment category.
Choosing the Right Tire
What should I consider when choosing a 2025 RAM Trucks 3500 tire?
Start with the correct primary size for the exact 2025 RAM Trucks 3500 sub-model, then compare the tire's construction, load capacity, and wheel compatibility. On this truck, that means paying close attention to whether the fitment is 235/80R17, 275/70R18, or 285/60R20 and whether the truck is dual rear wheel or single rear wheel.
After the fitment is confirmed, the next decision is matching the tire to the truck's real use. A work-oriented truck, tow rig, or mixed on-road and off-pavement setup may call for a different tread character than a highway-focused truck. Rim width, sidewall style, and tire weight are also useful comparison points when narrowing the final choice.
What sidewall styles are available for 2025 RAM Trucks 3500 tires?
Available sidewall styles for the 2025 RAM Trucks 3500 include RWL and RBL, depending on the tire size. The 275/70R18 BFGoodrich All Terrain TA KO2 uses an RWL sidewall, while the 235/80R17 version appears with an RBL sidewall treatment.
Sidewall styling mainly affects appearance, but it can still matter on a truck that balances work duty with a specific visual presentation. The important thing is to choose the sidewall style within the correct tire size rather than treating it as a separate fitment issue. Once the proper size is confirmed, the sidewall treatment becomes part of the final product-selection decision.
What brands offer tires for the 2025 RAM Trucks 3500?
BFGoodrich appears in the available product selection for the 2025 RAM Trucks 3500, specifically in the All Terrain TA KO2 series for 275/70R18 and 235/80R17 fitments. That gives buyers a recognizable heavy-duty radial option within two of the truck's primary tire sizes.
Brand is only one part of the decision on a heavy-duty truck like the 3500. It still makes sense to compare the available size, rim-width range, sidewall style, load figure, and the truck's intended use before settling on a specific tire. The right product is the one that matches the exact wheel setup and how the truck is actually driven or worked.
Restoration & Appearance
Which tire should I choose for a period-style 2025 RAM Trucks 3500?
A period-style question matters less on a 2025 RAM Trucks 3500 than on an older collector truck, but visual consistency still starts with the correct original fitment category for the exact sub-model. That means staying with the proper 17-inch, 18-inch, or 20-inch radial size rather than treating another 3500 size as close enough.
Appearance on a newer heavy-duty truck usually comes down to wheel package and sidewall presentation more than vintage-style construction choices. A truck with 20-inch wheels presents differently than one on 18s or a DRW setup on 17s, so matching the tire to the truck's factory-style wheel configuration is the cleanest way to preserve the intended look.
How does tire construction affect the appearance of a restored 2025 RAM Trucks 3500?
Tire construction is straightforward on the 2025 RAM Trucks 3500 because the primary fitments are radial across the model range. The visual difference is less about bias-ply versus radial and more about choosing the correct size, sidewall treatment, and tread style so the truck looks appropriate for its trim level and wheel package.
Raised white letter and black sidewall presentations can change the character of the truck even when the fitment remains correct. On a newer heavy-duty model, preserving the intended appearance usually means avoiding wheel-and-tire combinations that alter the truck's stance or proportions more than selecting among period-era construction types.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 RAM Trucks 3500?
Yes, modifications can affect tire fitment on a 2025 RAM Trucks 3500. Aftermarket wheels, suspension changes, lift or leveling kits, and conversions between stock and custom wheel packages can all change the space available for the original tire size and may alter the wheel width the tire is mounted on.
Even when the sidewall size matches one of the truck's original fitments, the actual setup still needs to be checked. Wheel diameter, width, offset, rear-wheel configuration, and clearance at full steering lock all matter. A quick inspection before replacement helps confirm that the truck still matches the fitment category associated with its current sub-model and wheel package.
What should I inspect before driving a 2025 RAM Trucks 3500 on new tires?
Before driving a 2025 RAM Trucks 3500 on new tires, inspect the wheel condition, valve stems, lug hardware, and the tire's mounted size against the truck's actual sub-model and wheel setup. It also helps to confirm inflation pressure, check for proper bead seating, and make sure there is no visible interference at the fenders or suspension.
A heavy-duty truck benefits from a careful walkaround after installation and again after the first short drive. Watch for uneven stance, rubbing during turns, or signs of air loss. On DRW models especially, maintaining the correct fitment and inflation is important to keep the tire setup working as intended under load and over distance.
How often should tires on a 2025 RAM Trucks 3500 be inspected?
Tires on a 2025 RAM Trucks 3500 should be inspected regularly, with a quick visual check before normal use and a closer inspection before towing, hauling, or a longer trip. Look for cuts, punctures, sidewall damage, irregular wear, and any loss of air pressure that could affect a heavy-duty truck's stability and carrying ability.
The inspection interval matters even more when the truck sees seasonal use, jobsite duty, or long periods parked between trips. A tire can have adequate tread and still develop age-related cracking or damage from impacts and curbing. Checking condition, pressure, and tread wear pattern routinely helps catch problems before they turn into a fitment or road-use issue.
