The 2023 RAM Trucks 3500 sits in the heavy-duty pickup world where towing, payload, and long-haul work matter as much as day-to-day road manners. Buyers looking at this exact truck usually are not asking whether it needs a modern radial tire, but which of its three radial sizes applies to the specific trim and wheel setup. This model uses 275/70R18, 285/60R20, or 235/80R17 depending on sub-model, with single-rear-wheel and dually configurations following different fitment paths. Available choices here also reflect practical differences in sidewall presentation and wheel-width compatibility. The key is matching the tire to the truck's exact sub-model, rim diameter, and intended use before comparing options.
Which Tire Size Is Right for The 2023 RAM Trucks 3500
Three tire sizes apply to the 2023 RAM Trucks 3500, and the right one depends first on the exact sub-model and wheel diameter. All three are radial fitments, but they span 17-inch, 18-inch, and 20-inch rims, so confirming the truck's actual wheel setup is the first step before comparing tire style, load capability, or product details.
Fit(s): Big Horn, Laramie, Limited Longhorn, and Tradesman
Construction: Radial|Rim: 18 in
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 2023 RAM Trucks 3500, this size serves certain single-rear-wheel configurations and keeps the buyer in an 18-inch wheel fitment. Available choices in this size include BFGoodrich's All-Terrain T/A KO2 with a raised white letter sidewall treatment. This size is worth choosing when the truck already carries 18-inch wheels and the sub-model calls for this specific fitment.
Fit(s): Big Horn, Laramie, Limited, and Limited Longhorn
Construction: Radial|Rim: 20 in
285/60R20 is a metric radial size that uses a 285-millimeter nominal section width, a 60-series profile, and a 20-inch rim diameter. For the 2023 RAM Trucks 3500, this size belongs to specific trims that use 20-inch wheels, so it should not be treated as interchangeable with the 17-inch or 18-inch fitments. Its lower-profile format gives it a different sizing character than the other primary options on this page. This is the size to evaluate when the truck's trim and wheel package place it on 20-inch rims from the start.
235/80R17 is a metric radial size where 235 is the nominal section width in millimeters, 80 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter. On the 2023 RAM Trucks 3500, this size is tied to dually configurations, making it a fitment that needs to stay matched to the truck's DRW setup and 17-inch wheels. Available product coverage includes the BFGoodrich All-Terrain T/A KO2 with a black sidewall presentation and a defined rim-width range. This size should be evaluated with wheel setup and heavy-duty use in mind rather than appearance alone.
Sub-model fitment varies across the 2023 RAM Trucks 3500 lineup, and wheel diameter changes with it. Checking the exact trim and whether the truck is a dually is essential before selecting a tire, because the 17-inch, 18-inch, and 20-inch sizes are tied to different configurations.

Tire Size & Fitment
What tire size fits a 2023 RAM Trucks 3500?
The 2023 RAM Trucks 3500 uses three primary tire sizes: 275/70R18, 285/60R20, and 235/80R17. All are radial sizes, but they do not apply across the lineup in the same way, because certain trims use either 18-inch or 20-inch wheels while dually configurations use the 17-inch fitment.
The practical first step is identifying the exact sub-model and confirming the actual wheel diameter on the truck. A Big Horn, Laramie, or Limited Longhorn may use more than one size, while DRW versions follow a different path, so replacement shopping should start with the truck's specific configuration rather than the model name alone.
What size rim does a 2023 RAM Trucks 3500 use?
Rim diameter on the 2023 RAM Trucks 3500 depends on the tire size and sub-model. The truck uses 17-inch rims with 235/80R17, 18-inch rims with 275/70R18, and 20-inch rims with 285/60R20. That means the 3500 does not have one universal wheel diameter across the entire model range.
Checking the wheel size before ordering tires is especially important on this truck because each primary size belongs to a different rim diameter. The sidewall lettering on the current tire can help confirm size, but the wheel itself and the exact trim or dually setup should also be verified if the truck has had wheel changes or aftermarket upgrades.
Why does the 2023 RAM Trucks 3500 have more than one tire size?
The 2023 RAM Trucks 3500 spans several trims and includes both single-rear-wheel and dual-rear-wheel configurations, so it uses more than one tire size. Single-rear-wheel versions may use 275/70R18 or 285/60R20 depending on trim and wheel package, while DRW models use 235/80R17.
That variation means the correct tire is tied to the truck's exact setup, not just the 3500 badge. Buyers should confirm whether the truck is a dually, then match the tire to the installed wheel diameter. This avoids cross-shopping sizes that belong to other trims or wheel packages and keeps the replacement process much more accurate.
Choosing the Right Tire
What should I consider when choosing a 2023 RAM Trucks 3500 tire?
Start with the exact tire size that belongs to the truck's sub-model and wheel diameter, because the 2023 RAM Trucks 3500 uses three different radial fitments. After that, compare the tire's construction, rim-width compatibility, load figure, and sidewall style so the replacement matches how the truck is actually used.
A working 3500 used for towing or hauling may put more emphasis on load-related specifications, while another owner may care more about wheel package and appearance. It also helps to confirm whether the truck is single-rear-wheel or dually, since that changes the fitment path immediately and affects which products are relevant.
What sidewall styles are available for 2023 RAM Trucks 3500 tires?
Sidewall style varies by the available tire and size. In the current product mix for the 2023 RAM Trucks 3500, 275/70R18 is available with an RWL sidewall, while 235/80R17 appears with an RBL sidewall. Those details affect the truck's visual presentation even when the tire remains within the correct size.
That makes sidewall choice part of the buying decision once size and wheel diameter are confirmed. Owners who want a more aggressive or more understated look should compare the available sidewall treatment in the exact fitment they need, since appearance options do not necessarily carry across every RAM 3500 size.
What tire series are available for the 2023 RAM Trucks 3500?
The available product range shown here centers on the BFGoodrich All-Terrain T/A KO2 series for the 2023 RAM Trucks 3500. It appears in both 275/70R18 and 235/80R17, giving those fitments a consistent all-terrain style while still preserving size-specific differences in wheel compatibility and load figures.
Even within one tire series, the details still matter. Buyers should compare the exact size, rim-width range, sidewall presentation, and load specification tied to the tire they are considering, because a series name alone does not make one 3500 fitment interchangeable with another.
Restoration & Appearance
Does correct tire fitment matter for a 2023 RAM Trucks 3500 restoration or appearance build?
Yes, correct tire fitment still matters on a 2023 RAM Trucks 3500 even when the goal is mainly appearance. The truck uses different wheel diameters and tire sizes across the lineup, so keeping the size matched to the sub-model and wheel package is the foundation before looking at sidewall style or tread character.
Appearance choices make more sense once the fitment is settled. A raised white letter sidewall creates a different look than a black sidewall, but either one should be evaluated within the right size for the truck. If originality or build accuracy matters closely, vehicle-specific build references and wheel details are worth checking first.
Which sidewall style suits a period-style or custom 2023 RAM Trucks 3500?
That depends on the look the truck is meant to carry. A raised white letter presentation can give a 2023 RAM Trucks 3500 a more assertive, off-road-influenced appearance, while a black sidewall keeps the look more restrained and work-truck oriented. Both approaches can suit the truck when they stay within the correct tire size.
The best approach is to choose the sidewall style after the fitment is confirmed for the trim and wheel diameter. A visual preference should not override correct sizing, especially on a heavy-duty truck where wheel compatibility and intended use still matter more than the cosmetic finish on the sidewall.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 RAM Trucks 3500?
Yes, modifications can change tire fitment on a 2023 RAM Trucks 3500. Aftermarket wheels, offset changes, suspension lifts, lowering kits, or other chassis changes can alter clearance and may affect whether the original tire size remains appropriate for the truck's current setup.
That is why the installed wheel diameter and width should be checked before replacing tires on a modified truck. Steering clearance, fender space, and rear dual-wheel spacing also deserve attention where applicable, especially if the truck no longer matches its original trim-level wheel package or has been set up for a specific type of work.
What should I inspect before driving a 2023 RAM Trucks 3500 on new tires?
Before road use, inspect tire pressure, wheel fastener security, valve stems, and basic clearance at the fenders and suspension. It also helps to verify that all tires match the intended size for the truck's exact configuration, especially on a 2023 RAM Trucks 3500 where single-rear-wheel and dually setups follow different fitment paths.
A short initial drive is useful for checking vibration, pull, or rubbing that may point to wheel or fitment issues. Rechecking pressure after installation and confirming that the tires seat properly on the correct rim width are smart steps, particularly on a heavy-duty truck that may see towing, hauling, or extended highway use.
How often should tires on a 2023 RAM Trucks 3500 be inspected?
Tires on a 2023 RAM Trucks 3500 should be inspected regularly rather than only when tread appears worn. Heavy-duty trucks benefit from routine checks for pressure loss, uneven wear, cuts, bulges, and sidewall damage, because load and road use can expose problems before they become obvious at a glance.
Monthly visual checks are a sensible habit, and inspections before towing, hauling, or longer highway trips are especially important. Trucks that sit for stretches should still have their tires reviewed for air loss and aging, while any change in ride feel, steering response, or vibration should prompt a closer look right away.
