The 2022 RAM Trucks 2500 sits firmly in the modern heavy-duty pickup world, where towing, payload, and off-pavement capability all influence tire choice as much as appearance. Unlike many collector-era vehicles, this truck can wear several different factory-style metric radial sizes depending on trim and wheel package. That makes the first decision less about bias-ply versus radial and more about confirming whether your truck uses 17-, 18-, or 20-inch wheels with sizes such as 245/70R17, 275/70R18, 285/70R17, or 285/60R20. From there, the focus shifts to matching the correct size to the exact sub-model, intended use, and wheel setup before choosing among the available tire options.
Which Tire Size Is Right for The 2022 RAM Trucks 2500
The 2022 RAM Trucks 2500 uses four primary tire sizes, and the correct one depends on the specific sub-model and wheel diameter. All of them are metric radial sizes, but they span 17-, 18-, and 20-inch rims, so confirming the exact wheel on your truck comes first. Once that is settled, the real comparison becomes load-oriented tire choice, rim-width compatibility, and whether the available product options match how the truck is actually used.
Fit(s): Big Horn, Laramie, Limited Longhorn, Lone Star, and Tradesman
Construction: Radial|Rim: 18 in
The 275/70R18 size uses modern metric radial sizing, with a 275-millimeter section width, a 70-series aspect ratio, radial construction, and fitment on an 18-inch rim. On the 2022 RAM Trucks 2500, this size serves several trim levels and reflects a heavy-duty pickup setup that balances sidewall height with substantial wheel diameter. Available options in this size include BFGoodrich All-Terrain T/A KO2 with raised white letter styling. This is the size to evaluate when your truck is equipped with 18-inch wheels and you want to compare tire specifications without moving away from the intended rim diameter.

The 285/60R20 size is also a modern metric radial, pairing a 285-millimeter section width with a 60-series profile on a 20-inch rim. For the 2022 RAM Trucks 2500, it represents one of the larger wheel-package fitments, so wheel diameter confirmation is especially important before selection. This size changes both the wheel and tire relationship compared with the 17- and 18-inch fitments used elsewhere in the lineup. It should be considered only for trucks already set up for the 20-inch package, with attention to maintaining proper clearance and overall compatibility if wheels have ever been changed.
The 285/70R17 designation means a 285-millimeter-wide metric radial tire with a 70-series profile built for a 17-inch rim. On the 2022 RAM Trucks 2500, this size is tied to the Power Wagon and carries a distinctly different fitment role from the truck's 18- and 20-inch options. BFGoodrich All-Terrain T/A KO2 is available here in raised white letter form, with more than one load-oriented specification in the same basic size. This is the size to review when the truck has the 17-inch Power Wagon wheel package and the goal is matching both the size and the tire's intended duty level.
The 245/70R17 size is a metric radial with a 245-millimeter section width, a 70-series aspect ratio, and fitment on a 17-inch rim. Within the 2022 RAM Trucks 2500 range, this size is associated with Tradesman applications and differs noticeably from the truck's wider 275- and 285-section alternatives. BFGoodrich All-Terrain T/A KO2 is available in this size with raised white letter sidewall treatment and heavy-duty load capability. It makes sense to focus on this size when the truck is equipped with the narrower 17-inch setup and the aim is to preserve the original wheel-to-tire relationship for that configuration.
Tire fitment on the 2022 RAM Trucks 2500 varies by sub-model, and several trims can use more than one wheel-and-tire package. Checking the exact trim matters because the truck range spans three rim diameters and four primary metric radial sizes.

2022 RAM Trucks 2500 Big Horn
The 2022 RAM Trucks 2500 Big Horn uses either a 275/70R18 or 285/60R20 radial fitment, depending on the wheel package. Tire selection starts with confirming whether the truck has 18-inch or 20-inch wheels, then choosing a tire that matches that setup and the truck's working or all-terrain use.
The 2022 RAM Trucks 2500 Laramie can be fitted with either 275/70R18 or 285/60R20 radial tires. That means the correct choice depends on the actual wheel diameter on the truck rather than the model name alone, especially if the wheels have been changed since new.
The 2022 RAM Trucks 2500 Limited uses the 285/60R20 radial size. Selection is more straightforward here, but it still helps to verify the truck remains on its correct 20-inch wheel setup before comparing tire specifications or replacing a full set.
The 2022 RAM Trucks 2500 Limited Longhorn uses either 275/70R18 or 285/60R20 radial tires. The practical decision is confirming which wheel package the truck actually carries, then comparing tire characteristics within that exact size instead of treating all Longhorn trucks the same.
The 2022 RAM Trucks 2500 Lone Star can use 275/70R18 or 285/60R20 radial tires. That makes wheel confirmation the key first step, followed by choosing a tire that suits the truck's intended mix of daily driving, towing, or rough-surface use.
The 2022 RAM Trucks 2500 Power Wagon uses the 285/70R17 radial size. Because that fitment is distinct within the 2500 lineup, tire selection should stay centered on the 17-inch wheel package and the specific load and use characteristics of the available tires in that size.
The 2022 RAM Trucks 2500 Tradesman uses either 245/70R17 or 275/70R18 radial tires. Choosing correctly starts with confirming whether the truck is on the 17-inch or 18-inch wheel setup, since those sizes are not interchangeable simply because they appear on the same trim family.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2022 RAM Trucks 2500?
The 2022 RAM Trucks 2500 uses four primary tire sizes: 245/70R17, 275/70R18, 285/70R17, and 285/60R20. All are radial metric sizes, but they do not apply universally across the lineup because different sub-models and wheel packages use different combinations.
The best starting point is the exact trim and the actual wheel diameter on the truck. A Tradesman, Power Wagon, Big Horn, or Limited may not share the same setup, and some trims can use more than one size, so reading the sidewall and confirming the installed wheel is the safest way to narrow the correct fitment.
What size rim does a 2022 RAM Trucks 2500 use?
A 2022 RAM Trucks 2500 can use 17-inch, 18-inch, or 20-inch rims depending on the sub-model and tire package. The 245/70R17 and 285/70R17 fitments use 17-inch rims, 275/70R18 uses an 18-inch rim, and 285/60R20 uses a 20-inch rim.
That rim diameter is the first thing to verify before replacing tires. Even when two trims share the same model name, the correct tire must match the wheel already on the truck, and any aftermarket wheel change should also be checked for proper width and clearance before choosing a replacement size.
Why does the 2022 RAM Trucks 2500 have more than one tire size?
The 2022 RAM Trucks 2500 spans several trims and wheel packages, so it uses more than one primary tire size. Some versions are set up with 17-inch wheels, others with 18-inch wheels, and others with 20-inch wheels, which naturally changes the tire size that belongs on the truck.
That variation means tire selection is tied to configuration, not just year and model name. Power Wagon fitment differs from Limited fitment, and trims such as Big Horn or Laramie may use one of two sizes, so identifying the truck's exact sub-model and current wheel setup prevents ordering the wrong diameter.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 RAM Trucks 2500?
Start with the exact size already assigned to the truck, then compare the tire's construction, load specification, rim-width range, and intended use. On the 2022 RAM Trucks 2500, that matters because the lineup includes several sizes and wheel diameters, not one universal fitment.
A truck used for work, towing, or rough surfaces may call for different priorities than one used mainly on pavement. It also helps to confirm whether the vehicle still has its original-style wheel package, since choosing within the correct size is very different from trying to substitute between 17-, 18-, and 20-inch setups.
What sidewall styles are available for 2022 RAM Trucks 2500 tires?
The available products shown for the 2022 RAM Trucks 2500 use RWL sidewalls, which is the raised white letter style. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options available in the supported 17-inch and 18-inch sizes shown here.
Sidewall appearance is worth considering if the truck's look matters as much as its use. Raised white letters create a more traditional all-terrain presentation, but the more important step is still choosing the correct tire size and wheel diameter first, then selecting the sidewall style available within that proper fitment.
What tire series are available for the 2022 RAM Trucks 2500?
The tire series shown for the 2022 RAM Trucks 2500 is BFGoodrich All-Terrain T/A KO2. It appears in the available 245/70R17, 275/70R18, and 285/70R17 product selections, giving the truck a consistent all-terrain style across those supported sizes.
That means the main comparison may come down to exact size, load specification, and rim-width compatibility rather than switching between several different series names. For a heavy-duty pickup, the right approach is to match the tire series to the truck's actual use only after confirming the correct wheel diameter and fitment for the trim.
Restoration & Appearance
Does correct tire fitment matter for a 2022 RAM Trucks 2500 restoration?
Correct tire fitment still matters even on a modern heavy-duty truck like the 2022 RAM Trucks 2500. Using the proper size for the trim and wheel package helps preserve the truck's intended stance, wheel-to-tire proportion, and overall presentation while keeping the fitment aligned with its original configuration style.
Appearance is only part of the equation, though. A truck restored or refreshed for show, collection, or careful road use should still have the wheel diameter, tire size, and load-oriented specifications checked closely, especially if replacement wheels or suspension changes entered the picture at any point in the truck's life.
How does tire construction affect the appearance of a restored 2022 RAM Trucks 2500?
On the 2022 RAM Trucks 2500, the primary fitments are radial tires, so construction is less about choosing between vintage bias-ply and radial looks and more about selecting a tire that keeps the truck's modern heavy-duty character intact. Sidewall treatment and overall tire profile do more to shape the appearance here.
A raised white letter all-terrain tire gives the truck a bolder visual statement than a plainer sidewall would. For an appearance-focused build, it helps to keep the correct size and rim diameter in place first, then choose the sidewall style and tire presentation that suits the truck's intended finish without distorting fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 RAM Trucks 2500?
Yes, modifications can affect tire fitment on a 2022 RAM Trucks 2500 even when the tire size itself is one of the original options. Changes such as aftermarket wheels, altered wheel width, different offset, suspension lifts, lowering, or body modifications can all influence how the tire sits and clears the truck.
A truck that has been modified should be checked more carefully than one still on its original-style setup. Wheel diameter, steering clearance, suspension travel, and fender space all matter, especially when moving between 17-, 18-, and 20-inch combinations or when using a wider size such as 285-section tires.
What should I inspect before driving a 2022 RAM Trucks 2500 on new tires?
Before driving a 2022 RAM Trucks 2500 on new tires, inspect the wheel diameter and width, confirm the tires are mounted in the correct size, and check inflation pressure, valve condition, and lug torque. A quick visual look for clearance at full steering lock is also worthwhile on a heavy-duty pickup.
The truck should then be watched for any rubbing, vibration, or uneven stance during the first miles of use. It also helps to keep an eye on air retention and tread wear as the tires settle in, particularly if the vehicle tows, carries heavy loads, or has aftermarket wheels or suspension changes.
How should tires on a 2022 RAM Trucks 2500 be inspected and maintained?
Tires on a 2022 RAM Trucks 2500 should be inspected regularly for tread wear, sidewall damage, cuts, punctures, bulges, and signs of air loss. Pressure should be checked consistently, and any uneven wear pattern should be addressed early because it can point to alignment, load, or suspension issues.
Heavy-duty trucks benefit from routine checks even when they are not driven every day. Looking over the tires before towing, hauling, or taking a longer trip helps catch problems sooner, and trucks that sit for stretches should still have their tires monitored for aging, flat spotting, and pressure loss between uses.
