2013 RAM Trucks Tire Fitment Guide

2013 RAM Trucks vehicles use eight sizes across nine model groups: 275/60R20, 265/70R17, and 285/45R22 on the 1500; 265/70R17, 285/70R17, and 245/70R17 on the 2500; and 275/70R18, 285/60R20, and 235/80R17 across the 3500 range, with ST and Tradesman using the 18-inch and 17-inch sizes only. Rim diameters therefore span 17, 18, 20, and 22 inches depending on the truck.

That means year and make alone are not enough for a correct choice on 2013 RAM Trucks. Start by identifying whether your truck is a 1500, 2500, or 3500, then confirm the actual wheel diameter on the vehicle. When product details are available, rim width ranges vary by size as well: for example, 235/80R17 uses 6.0 to 7.5-inch rims, 245/70R17 uses 6.5 to 8.0, 265/70R17 and 275/70R18 use 7.0 to 9.0, and 285/70R17 uses 7.5 to 9.5.

On a 2013 RAM Trucks tire, 265/70R17 means the tire has a nominal section width of 265 millimeters, a 70-series aspect ratio, radial construction, and fitment for a 17-inch wheel. That size appears on both the 2013 RAM Trucks 1500 and 2500, so it is one of the few sizes shared across two different truck lines in the range.

The important takeaway is that the code tells you both dimensions and wheel fitment, but it does not automatically tell you the service level you need. Within 265/70R17, there are versions with different load capacities and pressures, including 2,470 pounds at 50 psi and 3,195 pounds at 80 psi. A 1500 owner and a 2500 owner should therefore verify not only the size on the sidewall, but also the tire's load range and intended use before choosing.

No, 2013 RAM Trucks models do not all use the same tire size. The 1500 uses three sizes tied to 17-inch, 20-inch, and 22-inch wheel packages; the 2500 uses three different 17-inch sizes; and the 3500 family uses combinations of 17-inch, 18-inch, and 20-inch sizes depending on trim and equipment. Even within the 3500 range, not every trim uses the same full set of sizes.

That variation matters because the right tire choice starts with model identification, not with the brand name on the tailgate alone. A 3500 ST or Tradesman owner, for example, is looking at a different size path than a 3500 Laramie equipped with 20-inch wheels. Reading the current tire sidewall and confirming the wheel diameter are the fastest ways to avoid crossing over into a neighboring RAM model's fitment.

Sidewall styling for 2013 RAM Trucks tires includes both RWL and RBL depending on size. The 265/70R17, 285/70R17, 245/70R17, and 275/70R18 are available with raised white letters, while the 235/80R17 appears with a raised black letter sidewall. Those are visual differences, but they also matter to owners who want the truck's tire appearance to match its intended look.

On a 2013 RAM Trucks build, RWL tends to suit an off-road or period SUV-and-pickup accessory look that many truck owners still prefer, especially on all-terrain patterns. RBL gives a more understated appearance that often fits a fleet, towing, or work-focused presentation. If appearance matters as much as fitment, compare the sidewall style to your truck's trim level, wheel design, and the look you want before settling on a size-specific option.

BFGoodrich covers the available 2013 RAM Trucks fitments shown here, specifically through the All-Terrain T/A KO2 line in 265/70R17, 285/70R17, 245/70R17, 275/70R18, and 235/80R17. Those are all radial truck tires, and the sidewall finish varies by size, with raised white letters on most and raised black letters on the 235/80R17.

That concentration around one established truck-tire brand means the real comparison is often within the same series rather than between unrelated brands. For a 2013 RAM Trucks owner, the practical checkpoints become exact size, wheel diameter, speed symbol, and load capacity. Once those match the truck's application, then appearance details such as RWL versus RBL become the finishing decision rather than the starting point.

The two 265/70R17 options for 2013 RAM Trucks share the same BFGoodrich All-Terrain T/A KO2 series, the same 17-inch rim diameter, the same 7.0 to 9.0-inch approved rim width range, the same RWL sidewall style, and the same S speed symbol. Their key differences are service level and mass: one carries 2,470 pounds at 50 psi and weighs 45.7 pounds, while the other carries 3,195 pounds at 80 psi and weighs 53.5 pounds.

That makes the choice less about appearance and more about matching the truck's duty cycle. A lightly equipped 1500 and a work-oriented 2500 may both wear 265/70R17, but they do not necessarily ask the same thing from the tire. Before choosing between them, compare your door-jamb tire information, current load range, and how the truck is actually used for towing, payload, and highway driving.

Several 2013 RAM Trucks sizes have clear approved rim width ranges. The 235/80R17 fits 6.0 to 7.5-inch rims, the 245/70R17 fits 6.5 to 8.0-inch rims, the 265/70R17 and 275/70R18 fit 7.0 to 9.0-inch rims, and the 285/70R17 fits 7.5 to 9.5-inch rims. Those ranges are specific to each size and should not be transferred from one tire size to another.

Rim width matters because it influences section shape, tread profile, and how the tire sits on the wheel. A size that matches the wheel diameter can still be wrong if the wheel is too narrow or too wide for the tire's approved range. Before changing from one 2013 RAM Trucks size to another, verify the wheel width on the truck or confirm it with the wheel manufacturer so the tire stays within its intended fitment envelope.

The available 2013 RAM Trucks tire offerings shown here do not use tube-type markings, and the radial truck sizes covered are presented as modern tubeless-style applications rather than tube-type fitments. That aligns with the way 2013 RAM Trucks pickups were built, using modern wheel and tire standards rather than vintage tube-required construction.

Even so, the wheel itself still needs to be in proper condition. Confirm that the bead seats are clean, the valve stem is correct for the wheel and pressure range, and any older or damaged wheel has no sealing issues before mounting a new tire. On a truck that sees towing or heavy hauling, small air-loss issues become more important because pressure stability directly affects load carrying and handling.

Original 2013 RAM Trucks wheels can be used only with the tire sizes that match their wheel diameter and approved width range. A 17-inch wheel can take the 17-inch sizes used on certain 1500, 2500, and 3500 models, an 18-inch wheel is for the 275/70R18, a 20-inch wheel is for sizes such as 275/60R20 or 285/60R20, and a 22-inch wheel is for the 285/45R22.

The practical point is that wheel diameter is the first filter, but it is not the only one. Within the 17-inch group alone, 2013 RAM Trucks uses several different widths and aspect ratios, and they do not all share the same approved rim width range or load profile. If you are reusing factory wheels, verify both wheel diameter and wheel width before moving from one original RAM size to another.

A 2013 RAM Trucks should be stored away from direct sunlight, standing moisture, and ozone-producing equipment such as electric motors, battery chargers, and welders. Inflate the tires to the vehicle's recommended pressure, keep the truck on a clean surface, and move it periodically if it sits for long stretches. Radial tires generally tolerate storage well, but any tire can develop issues from long-term underinflation or static loading.

Owners who park a 2013 RAM Trucks seasonally should also think about the truck's weight and how it rests on the tires. If storage will be extended, rolling the truck occasionally or supporting it correctly can reduce the chance of temporary flat spotting and stress on the carcass. A quick visual check before the truck goes into storage and again before it returns to the road helps catch cracks, punctures, and pressure loss early.

Tires on a 2013 RAM Trucks should be judged by age as much as by tread depth, especially on trucks that are driven irregularly. A sensible rule is to begin evaluating them closely once they are around five to seven years old and to treat ten years as a strong point for replacement consideration regardless of remaining tread. The DOT date code on the sidewall is the quickest way to confirm the tire's true age.

That approach matters because many RAM trucks accumulate miles unevenly. A truck used for seasonal towing, hobby hauling, or occasional home-improvement duty may still have plenty of tread while the rubber itself has aged past its best years. For a 2013 RAM Trucks owner, age, cracking, hardening, and air retention often tell a more important story than tread wear alone when deciding whether a tire is still serviceable.

Tires on a 2013 RAM Trucks should be inspected before every drive and again before any longer trip or towing run. Check for visible cracking, cuts, punctures, bulges, uneven wear, embedded debris, and air-pressure loss. On heavier-duty 2500 and 3500 applications, pressure consistency is especially important because load-carrying demands can change quickly with cargo or trailer use.

A more thorough inspection every month is a good habit, even if the truck is driven only occasionally. Look across the full tread face for shoulder wear or center wear that might point to alignment or inflation issues, and make sure the valve stems remain sound. Catching a small problem in the driveway is far easier than dealing with a failed tire after the truck is loaded and headed down the highway.

Yes, 2013 RAM Trucks tires in these sizes are suitable for highway driving when they are in good condition, properly inflated, and matched to the truck's intended load. The available speed ratings here include Q at 99 mph, R at 106 mph, and S at 112 mph depending on size and version. Those ceilings are well above normal U.S. highway speeds, although a loaded heavy-duty pickup places very different demands on a tire than an unloaded commuter truck.

For a 2013 RAM Trucks owner, safety on the highway is usually about overall condition and proper service rating more than outright top-speed capability. Tread depth, age, pressure, alignment, suspension wear, and trailer weight all affect real-world confidence. On older or heavily used pickups, the truck's brakes, steering components, and load balance are often just as important as the tire's speed symbol when preparing for sustained highway use.

Inflation pressure for 2013 RAM Trucks tires should follow the truck's original placard or owner's manual for the exact model and use condition, then be checked against the tire's own service limits. Available examples include 265/70R17 at 2,470 pounds at 50 psi or 3,195 pounds at 80 psi, 285/70R17 at 2,755 pounds at 50 psi or 3,195 pounds at 80 psi, 245/70R17 at 3,000 pounds at 80 psi, 275/70R18 at 3,640 pounds at 80 psi, and 235/80R17 at 3,085 pounds at 80 psi.

Those figures are load-and-pressure capacities, not universal instructions to run every 2013 RAM Trucks tire at the same pressure. A half-ton 1500 and a one-ton 3500 can require very different pressures even if the tire dimensions look similar at a glance. Use the truck's factory recommendation as the baseline, then make sure the tire itself is appropriate for that requirement rather than borrowing a pressure figure from another RAM size.

Before taking a 2013 RAM Trucks on a longer drive, inspect every tire for cracking, cuts, bulges, punctures, exposed cords, and uneven wear, then confirm cold inflation pressures and check the spare as well. A heavy-duty RAM that may tow or carry substantial payload should also have its tire load capacity matched to the trip's expected use. If the truck has been sitting, pay extra attention to pressure loss and any vibration during the first miles.

Tires are only one part of the pre-drive checklist on a full-size pickup, especially a working 2500 or 3500. Wheel-nut torque, brakes, steering response, shocks, trailer connections, and lighting all matter on a longer run. Treat the tires as the foundation of the inspection: if they are the wrong size, underinflated, aged out, or damaged, the rest of the truck's capability cannot make up for that weakness.
