The 2026 RAM Trucks 3500 sits in the heavy-duty pickup world where payload, towing confidence, and trim-specific equipment have a direct effect on tire selection. Single-rear-wheel and dual-rear-wheel versions serve very different jobs, and that shows up clearly in the factory tire sizing. This truck uses three primary radial sizes: 235/80R17, 275/70R18, and 285/60R20, depending on the exact sub-model. That means the main decision is not simply choosing a tire brand, but first confirming whether the truck is DRW, standard SRW, or a Night Edition or upper-trim setup with 20-inch wheels. Getting that right keeps load capacity, wheel fitment, and overall stance aligned with the truck’s intended use.
Which Tire Size Is Right for The 2026 RAM Trucks 3500
The 2026 RAM Trucks 3500 uses three different tire sizes, and they vary by sub-model and wheel diameter. Before choosing a tire, confirm the exact trim and whether the truck is a dual-rear-wheel configuration, because this lineup spans 17-inch, 18-inch, and 20-inch rims. Once that is settled, the decision shifts to selecting the right radial tire for the truck’s load demands, wheel width, and intended use.
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 wheel diameter in inches. On the 2026 RAM Trucks 3500, this size serves certain single-rear-wheel trims and keeps the truck on an 18-inch rim. Available choices in this size include a BFGoodrich All-Terrain T/A KO2 with raised white letter styling. It is a useful fitment to evaluate when the truck retains its original 18-inch wheel setup and needs a tire matched to that specific rim diameter and width range.
Fit(s): Big Horn (DRW), Big Horn (DRW) w/Night Edition, Laramie (DRW), Laramie (DRW) w/Night/Sport Pkg., Limited (DRW), Limited Longhorn (DRW), and Tradesman (DRW)
Construction: Radial|Rim: 17 in
235/80R17 is a metric radial size that uses a 235-millimeter nominal section width, an 80-series profile, radial construction, and a 17-inch wheel diameter. This size is tied to the dual-rear-wheel versions of the 2026 RAM Trucks 3500, making it especially important to identify a DRW truck before selecting a replacement tire. In the available product range, this size appears as a BFGoodrich All-Terrain T/A KO2 with a black sidewall treatment. It should be chosen only after confirming the truck’s dually wheel package and the wheel width used on that 17-inch setup.
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 where 285 gives the nominal section width in millimeters, 60 indicates the profile, R marks radial construction, and 20 refers to the wheel diameter in inches. On the 2026 RAM Trucks 3500, this size appears on certain Night Edition and upper-trim single-rear-wheel configurations that use 20-inch wheels. The practical focus here is confirming that the truck actually has the 20-inch wheel package, since it does not share rim diameter with the other primary fitments. That makes this size a trim-specific choice rather than a general replacement across the full 3500 lineup.
Tire fitment on the 2026 RAM Trucks 3500 changes across the sub-model range, with different trims using different rim diameters and tire sizes. Checking the exact sub-model matters because DRW trucks, standard single-rear-wheel trucks, and Night Edition or premium trims do not all use the same fitment.

2026 RAM Trucks 3500 Big Horn
The 2026 RAM Trucks 3500 Big Horn uses the 275/70R18 radial fitment. Tire selection here centers on choosing an 18-inch radial that matches the truck’s wheel setup and intended use without drifting into the DRW or 20-inch trim fitments.
The 2026 RAM Trucks 3500 Big Horn (DRW) uses the 235/80R17 radial size. That makes dually identification the key first step, followed by confirming the 17-inch wheel package before choosing a replacement tire.
2026 RAM Trucks 3500 Big Horn (DRW) w/Night Edition
The 2026 RAM Trucks 3500 Big Horn (DRW) w/Night Edition also uses the 235/80R17 radial fitment. Even with the Night Edition designation, tire selection still needs to follow the dually-specific 17-inch setup rather than the larger-wheel SRW packages.
The 2026 RAM Trucks 3500 Big Horn w/Night Edition uses the 285/60R20 radial size. Choosing tires for this sub-model starts with confirming the 20-inch wheel package, since that fitment differs from both the standard Big Horn and the DRW versions.

Tire Size & Fitment
What tire size fits a 2026 RAM Trucks 3500?
The 2026 RAM Trucks 3500 uses three primary tire sizes: 235/80R17, 275/70R18, and 285/60R20. All three are radial fitments, and the correct size depends on the exact sub-model rather than applying across every 3500 configuration.
The first thing to confirm is whether the truck is a dual-rear-wheel model, a standard single-rear-wheel trim, or a version equipped with 20-inch wheels such as certain Night Edition or upper-trim packages. Matching the tire to the truck’s actual wheel diameter is just as important as matching the size code itself.
What size rim does a 2026 RAM Trucks 3500 use?
A 2026 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.
Because this truck family spans three wheel diameters, checking the wheel itself before ordering tires is essential. A trim name, package, or DRW designation matters here, and any truck that has had wheel changes over time should be measured and verified rather than assumed from appearance alone.
Why does the 2026 RAM Trucks 3500 have more than one tire size?
The 2026 RAM Trucks 3500 has more than one tire size because the lineup includes different trims and both single-rear-wheel and dual-rear-wheel configurations. Those equipment differences lead to three separate radial fitments: 235/80R17, 275/70R18, and 285/60R20.
That means tire selection starts with identifying the truck’s exact configuration, not just the model name on the badge. A dually setup points toward the 17-inch fitment, while certain SRW trims use 18-inch or 20-inch wheels, so confirming the actual wheel package prevents an expensive mismatch.
Choosing the Right Tire
What should I consider when choosing a tire for a 2026 RAM Trucks 3500?
Start with the correct size for the truck’s exact sub-model, since the 2026 RAM Trucks 3500 may use 235/80R17, 275/70R18, or 285/60R20. After that, compare construction, load capacity, rim-width compatibility, and the type of use the truck sees, whether that is towing, hauling, or mixed on-road and off-road driving.
The available products also show that sidewall style and tire series can matter. A tire should match the wheel diameter first, then the wheel width and expected duty, especially on a heavy-duty truck where the wrong size or a mismatched specification can create clearance or load-related concerns.
What sidewall styles are available for 2026 RAM Trucks 3500 tires?
The available 2026 RAM Trucks 3500 tire options include both raised white letter and black sidewall presentations. In the current product range, the 275/70R18 BFGoodrich All-Terrain T/A KO2 uses RWL styling, while the 235/80R17 version appears with an RBL sidewall treatment.
Sidewall style is mainly an appearance choice, but it can still help narrow the right product once the correct size is confirmed. It should never be used in place of fitment details, since the truck’s sub-model, wheel diameter, and load-related requirements still determine which tire belongs on the vehicle.
What brands offer tires for the 2026 RAM Trucks 3500?
BFGoodrich is represented in the current tire selection for the 2026 RAM Trucks 3500. The available products shown for applicable sizes are from the BFGoodrich All-Terrain T/A KO2 line in radial construction.
Brand is only one part of the decision on a heavy-duty truck like this. It still makes sense to compare the exact size, sidewall style, load figure, rim-width specification, and whether the tire matches the truck’s 17-inch, 18-inch, or 20-inch wheel package before making a final choice.
Restoration & Appearance
Does correct tire fitment matter for a 2026 RAM Trucks 3500 build?
Correct tire fitment matters on a 2026 RAM Trucks 3500 because the truck uses multiple wheel diameters and trim-specific tire sizes. A 235/80R17 dually setup, a 275/70R18 SRW setup, and a 285/60R20 upper-trim fitment do not serve the same wheel package or visual stance.
Appearance is part of the equation, but proper fitment comes first. Choosing a tire that matches the intended look while staying true to the truck’s actual sub-model helps preserve proportion, wheel-to-tire balance, and safe clearance, especially if the truck has appearance packages or aftermarket wheel changes.
How does tire construction affect the appearance of a 2026 RAM Trucks 3500?
The primary fitments for the 2026 RAM Trucks 3500 are radial tires, so the appearance question is less about bias-ply versus radial and more about profile, wheel diameter, and sidewall presentation. A 17-inch, 18-inch, or 20-inch setup changes the truck’s visual character more than construction type alone.
Sidewall treatment also contributes to the final look. Raised white letter and black sidewall options create different visual impressions, but they still need to be chosen within the correct size for the truck’s actual trim and wheel package so the appearance stays aligned with proper fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2026 RAM Trucks 3500?
Yes, modifications can affect tire fitment on a 2026 RAM Trucks 3500. Aftermarket wheels, suspension changes, leveling or lowering kits, and body alterations can change clearance, wheel-width requirements, and the way a 235/80R17, 275/70R18, or 285/60R20 tire sits on the truck.
Any truck that has been changed from its original wheel or suspension setup should be checked carefully before replacement tires are chosen. Wheel diameter is only part of the picture, since width, offset, steering clearance, and rear dual-wheel spacing can all influence whether the selected tire is appropriate.
What should I inspect before driving a 2026 RAM Trucks 3500 on new tires?
Before driving a 2026 RAM Trucks 3500 on new tires, inspect wheel condition, verify tire pressure, and make sure the installed size matches the truck’s actual wheel diameter and configuration. It also helps to confirm there is no rubbing at full steering lock and no visible interference around suspension or body components.
A heavy-duty truck places real demand on its tires, so a quick check for proper inflation, secure valve stems, and even seating on the rim is worthwhile before regular road use. On DRW trucks, rear spacing and clearance between duals should also be reviewed after installation.
How often should tires on a 2026 RAM Trucks 3500 be inspected?
Tires on a 2026 RAM Trucks 3500 should be inspected regularly, especially before towing, hauling, or longer highway trips. Frequent visual checks for uneven wear, cuts, punctures, cracking, bulges, and air loss are important on a truck that may carry substantial load or spend time under heavy use.
Inspection becomes even more important when the truck is used seasonally or sits for periods between jobs. Looking over tread condition, sidewalls, and inflation on a routine basis helps catch problems early and confirms that the tires are still appropriate for the wheel setup currently on the truck.
