The 2013 RAM Trucks 2500 sits in the heavy-duty pickup market where towing, payload, and four-wheel-drive capability matter just as much as day-to-day road manners. Buyers looking at this truck usually need tire fitment that matches the exact trim and intended use, because RAM gave the 2500 more than one 17-inch tire size across the lineup. Most sub-models use 265/70R17 radials, while ST and Tradesman models use 245/70R17 and the Power Wagon steps up to 285/70R17. Available choices stay focused on rugged radial construction with raised white letter styling, so the real job is matching the truck's exact sub-model, wheel setup, and load needs before choosing a tire.
Which Tire Size Is Right for The 2013 RAM Trucks 2500
The 2013 RAM Trucks 2500 uses three primary tire sizes, and the right one depends on the exact sub-model rather than a change in wheel diameter. All three fitments are radial tires for 17-inch rims. The first step is identifying whether the truck is an ST or Tradesman, a standard 2500 trim such as Big Horn or Laramie, or a Power Wagon, then comparing load specification, wheel width, and intended use within that correct size.
Fit(s): Big Horn 4x2, Big Horn 4x4, Laramie 4x2, Laramie 4x4, Laramie Longhorn 4x2, Laramie Longhorn 4x4, Lone Star 4x2, Lone Star 4x4, Outdoorsman, SLT 4x2, and SLT 4x4
Construction: Radial|Rim: 17 in
A 265/70R17 uses a 265-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 17-inch rim. On the 2013 RAM Trucks 2500, this is the common fitment used across many sub-models, making it the size most owners will be shopping for. Available choices include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls and more than one load specification. This size makes sense when the truck falls into the broad middle of the 2500 lineup and the goal is to stay with the original fitment category while checking wheel width and working load requirements carefully.
A 285/70R17 is a metric radial with a 285-millimeter nominal width, a 70-series profile, and a 17-inch rim diameter. On this 2013 RAM Trucks 2500 lineup, it is the larger primary fitment tied to the Power Wagon rather than the full range of sub-models. BFGoodrich All-Terrain T/A KO2 options are available in this size with raised white letter styling and differing load specifications. This size should be evaluated as a Power Wagon fitment first, with close attention to wheel-width range and the truck's actual wheel setup before treating it as the right choice.
Fit(s): ST 4x2, ST 4x4, Tradesman 4x2, and Tradesman 4x4
Construction: Radial|Rim: 17 in
A 245/70R17 is a metric radial tire with a 245-millimeter nominal width, a 70-series aspect ratio, and a 17-inch wheel diameter. For the 2013 RAM Trucks 2500, this size belongs to ST and Tradesman configurations rather than the higher trims or the Power Wagon. The available BFGoodrich All-Terrain T/A KO2 option uses raised white letter sidewalls and a load-focused LT-format construction approach. This size is the one to compare when the truck is equipped as a work-oriented ST or Tradesman and the priority is preserving the correct basic fitment before comparing load capacity and wheel-width compatibility.
Sub-model fitment matters on the 2013 RAM Trucks 2500 because tire size changes across the lineup even though all three sizes use 17-inch rims. Identifying the exact trim is the key step before comparing products, load specifications, or wheel-width requirements.

Tire Size & Fitment
What tire size fits a 2013 RAM Trucks 2500?
A 2013 RAM Trucks 2500 uses one of three radial tire sizes: 245/70R17, 265/70R17, or 285/70R17. The correct size depends on the sub-model. ST and Tradesman models use 245/70R17, most Big Horn, Laramie, Laramie Longhorn, Lone Star, Outdoorsman, and SLT models use 265/70R17, and the Power Wagon uses 285/70R17.
The key is identifying the exact trim before choosing a tire, because all three sizes use 17-inch rims and can look similar at a glance. Checking the truck's current tire placard, wheel setup, and any past modifications helps prevent choosing a size that belongs to a different 2500 configuration.
What size rim does a 2013 RAM Trucks 2500 use?
The tire fitments covered for the 2013 RAM Trucks 2500 all use a 17-inch rim diameter. That applies to 245/70R17, 265/70R17, and 285/70R17, so the wheel diameter stays consistent even though the tire width and overall proportions vary by sub-model.
Wheel diameter is only part of the fitment picture on a heavy-duty truck. Rim width also matters, especially when comparing 245-, 265-, and 285-width tires, so it is worth confirming the actual wheel dimensions before changing tire size or replacing wheels that may have been swapped by a prior owner.
Why does the 2013 RAM Trucks 2500 have more than one tire size?
The 2013 RAM Trucks 2500 has more than one tire size because different sub-models were equipped for different roles within the lineup. ST and Tradesman models use 245/70R17, the majority of trims use 265/70R17, and the Power Wagon uses 285/70R17, all in radial construction on 17-inch rims.
That means the correct tire is tied to the truck's exact configuration, not just the model name. A buyer should verify the trim, current wheel setup, and whether the truck still carries its intended suspension and wheel package before selecting a replacement tire from a different size group.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 RAM Trucks 2500?
Start with the correct size for the exact sub-model, since the 2013 RAM Trucks 2500 uses 245/70R17, 265/70R17, or 285/70R17 depending on trim. From there, compare radial tire specifications such as load capacity, wheel-width range, and whether the tire suits the truck's real use, whether that is commuting, towing, work duty, or mixed off-road driving.
A heavy-duty pickup places more importance on matching the tire to actual carrying demands than simply matching the sidewall size. It also helps to confirm whether the truck still has stock wheels, because an aftermarket wheel can change the right range of tire widths even when the rim diameter remains 17 inches.
What sidewall styles are available for 2013 RAM Trucks 2500 tires?
The available tires for the 2013 RAM Trucks 2500 use an RWL sidewall, which means raised white letter styling. That appearance is offered across the BFGoodrich All-Terrain T/A KO2 options in the applicable 245/70R17, 265/70R17, and 285/70R17 sizes.
Sidewall style affects the truck's visual character more than its core fitment, so the first priority remains choosing the correct size and load specification for the trim. Once those basics are right, raised white letters can be part of the decision if the goal is a more aggressive, traditional light-truck look.
What brands offer tires for the 2013 RAM Trucks 2500?
The available tire options for the 2013 RAM Trucks 2500 are from BFGoodrich. The applicable products are in the All-Terrain T/A KO2 line across the covered 17-inch sizes, with different specifications depending on the exact tire size and intended load range.
Since brand choice is narrow here, the more useful comparison is within the available BFGoodrich options. Owners should focus on the exact size for the truck's trim, then compare load capacity, wheel-width range, and the truck's intended work or recreational use before settling on a specific tire.
Restoration & Appearance
Does correct tire fitment matter for a 2013 RAM Trucks 2500 restoration?
Correct tire fitment still matters on a 2013 RAM Trucks 2500 even though it is newer than traditional collector-era vehicles. Using the proper trim-based size preserves the truck's intended stance and keeps the wheel-and-tire presentation consistent with the way that particular 2500 configuration was equipped.
Appearance is only one reason to stay with the right fitment. A truck restored or refreshed with the wrong width or profile can also create avoidable clearance and wheel-compatibility issues, so confirming the exact sub-model and the actual 17-inch wheel setup is a smart step before choosing replacement tires.
How does tire construction affect the appearance of a restored 2013 RAM Trucks 2500?
On the 2013 RAM Trucks 2500, the primary fitments are radial tires, so construction choice is less about switching between vintage bias-ply and radial looks and more about selecting the right modern truck tire presentation. The available options also use raised white letter sidewalls, which give the truck a more assertive, off-road-oriented visual character.
For a restoration-minded owner, the better question is whether the tire's size, sidewall treatment, and overall character suit the trim being recreated. A Power Wagon, for example, should not be approached the same way as an ST or Tradesman, so matching the truck's correct fitment group remains the foundation of a convincing result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 RAM Trucks 2500?
Yes, modifications can affect tire fitment on a 2013 RAM Trucks 2500 even when the replacement tire matches one of the original 17-inch sizes. Wheel-width changes, different offsets, suspension lifts or leveling kits, and prior tire-size changes can all alter how a 245/70R17, 265/70R17, or 285/70R17 sits in the wheel opening.
A truck that has been modified should be checked for steering clearance, fender clearance, and actual wheel dimensions before a new set goes on. That matters most when moving between width classes, because a size that is correct for one 2500 sub-model may not be the right choice for another setup.
What should I inspect before driving a 2013 RAM Trucks 2500 on new tires?
Before driving a 2013 RAM Trucks 2500 on new tires, inspect the wheels for correct diameter and condition, confirm lug hardware is appropriate, and make sure the tire size matches the truck's exact trim. It is also wise to check suspension wear, steering components, and brake condition on a heavy-duty truck that may see towing or hauling duty.
After installation, pay attention to inflation pressure, sidewall clearance, and any rubbing at full steering lock or under suspension movement. A short road test can reveal vibration, pull, or contact issues early, and those are easier to address before the truck goes back into regular work or longer highway use.
How often should tires on a 2013 RAM Trucks 2500 be inspected?
Tires on a 2013 RAM Trucks 2500 should be inspected regularly, especially if the truck tows, hauls, or spends time off pavement. Frequent visual checks for uneven wear, cuts, cracking, punctures, and air loss are important, and a closer inspection is worthwhile before long trips or any period of heavier-duty use.
Heavy-duty trucks can hide tire problems until the load goes up, so condition matters as much as tread depth. Looking over the sidewalls, checking pressure when the tires are cold, and watching for irregular wear patterns can help catch alignment, suspension, or wheel issues before they become bigger fitment or safety concerns.
