The 2017 RAM Trucks 2500 sits in the heavy-duty pickup segment where towing, payload, and real-world durability matter as much as day-to-day ride quality. Buyers often choose this truck for work use, long-distance hauling, or off-pavement confidence, so tire selection has a direct effect on stance, load support, and clearance. Tire fitment on the 2017 RAM Trucks 2500 is entirely radial, but the exact size changes by sub-model and wheel package, spanning 17-, 18-, and 20-inch rims. Available choices here lean toward BFGoodrich All-Terrain T/A KO2 products with raised white letter sidewalls. The key is matching the truck's exact trim and wheel setup before comparing tire details.
Which Tire Size Is Right for The 2017 RAM Trucks 2500
The 2017 RAM Trucks 2500 uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All of these fitments are radial, but they span 17-, 18-, and 20-inch rims, so the first step is confirming both the trim and the truck's actual wheel setup before selecting a tire.
Fit(s): Big Horn, Laramie, Laramie Longhorn, SLT, and Tradesman
Construction: Radial|Rim: 18 in
A 275/70R18 tire uses a 275-millimeter nominal section width, a 70-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2017 RAM Trucks 2500, this is one of the core heavy-duty fitments and appears across several sub-models that use 18-inch wheels. Available choices in this size include BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls and a 7.0- to 9.0-inch rim-width range. This size is worth choosing when the truck is already equipped with the correct 18-inch wheel package and the goal is to stay with the intended overall fitment profile.
Fit(s): Big Horn, Laramie, Laramie Longhorn, Limited, and SLT
Construction: Radial|Rim: 20 in
A 285/60R20 tire combines a 285-millimeter section width with a 60-series profile, radial construction, and a 20-inch rim. On the 2017 RAM Trucks 2500, this size serves trims that carry the larger 20-inch wheel setup rather than the 17- or 18-inch alternatives. The lower profile and larger rim diameter make wheel confirmation especially important before moving ahead with any replacement. This is the size to evaluate when the truck already wears the factory-style 20-inch arrangement and you want to preserve the same basic fitment format.
A 285/70R17 tire is a metric radial with a 285-millimeter nominal section width, a 70-series aspect ratio, and a 17-inch rim diameter. For the 2017 RAM Trucks 2500, this size is tied to the Power Wagon and reflects a distinct 17-inch wheel fitment from the truck's other trims. Available BFGoodrich All-Terrain T/A KO2 options use raised white letter sidewalls and share a 7.5- to 9.5-inch rim-width range, with different load-capacity versions available. This size deserves close attention when replacing tires on a Power Wagon, since it is not interchangeable with the truck's 18- or 20-inch fitments.
A 245/70R17 tire uses a 245-millimeter section width, a 70-series profile, radial construction, and a 17-inch rim. On the 2017 RAM Trucks 2500, this is a narrower 17-inch fitment associated with certain Tradesman configurations rather than the broader 17-inch Power Wagon size. BFGoodrich All-Terrain T/A KO2 is available here with a raised white letter sidewall and a 6.5- to 8.0-inch rim-width range. This size should be matched carefully to the truck's existing wheel package, especially if the vehicle has seen wheel swaps or trim-based equipment changes over time.
Fitment across the 2017 RAM Trucks 2500 lineup is not one-size-fits-all, because several trims can use different wheel and tire combinations. Checking the exact sub-model matters before comparing products, especially where 17-, 18-, and 20-inch setups overlap within the same model year.

2017 RAM Trucks 2500 Big Horn
The 2017 RAM Trucks 2500 Big Horn uses either an 18-inch or 20-inch radial tire setup, so replacement choice begins with confirming which wheel package is on the truck. That makes wheel-diameter verification just as important as the trim name before selecting a tire.
The 2017 RAM Trucks 2500 Laramie also spans both 18-inch and 20-inch radial fitments rather than one universal size. Tire selection depends on matching the truck's actual wheel setup first, then comparing the appropriate options within that size.
The 2017 RAM Trucks 2500 Laramie Longhorn can use either of two radial sizes tied to different wheel diameters. The practical takeaway is to confirm the wheel package on the truck before treating another Longhorn's tire size as a safe guide.
The 2017 RAM Trucks 2500 Limited uses the 20-inch radial fitment rather than the 17-inch or 18-inch alternatives seen elsewhere in the lineup. That keeps selection more straightforward, with the main focus shifting to matching the existing wheel setup and intended use.
The 2017 RAM Trucks 2500 Power Wagon uses a dedicated 17-inch radial size that differs from the truck's 18-inch and 20-inch fitments. Choosing tires here means staying focused on the Power Wagon's specific setup instead of assuming another 2500 trim shares the same dimensions.
The 2017 RAM Trucks 2500 SLT uses either an 18-inch or 20-inch radial tire size depending on the wheel configuration. That makes visual wheel confirmation important before replacement, even when the trim name is already known.
The 2017 RAM Trucks 2500 Tradesman can use either a 17-inch or 18-inch radial fitment, which creates more variation than a single-size trim. Tire selection should start by confirming the wheel diameter on the truck and then narrowing choices within the correct size.
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.
Best 2017 RAM Trucks 2500 Tires for Sale
Available 2017 RAM Trucks 2500 tire choices center on BFGoodrich All-Terrain T/A KO2 products in the supported 17-inch and 18-inch sizes. The main comparison points are size, load-capacity version, rim-width compatibility, and the shared raised white letter sidewall presentation.
Owners of a 2017 RAM Trucks 2500 usually need to sort out trim-specific tire size, wheel diameter, and product differences before replacing a set. The questions below focus on fitment, radial tire selection, appearance, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2017 RAM Trucks 2500?
The 2017 RAM Trucks 2500 uses four primary tire sizes: 275/70R18, 285/60R20, 285/70R17, and 245/70R17. All are radial sizes, but they do not apply across the lineup in the same way, because different sub-models and wheel packages use different combinations.
The most important step is identifying the exact trim and confirming the truck's current wheel diameter. A Power Wagon, for example, does not share the same fitment path as a Limited, and a Tradesman may use either a 17-inch or 18-inch setup depending on configuration.
What size rim does a 2017 RAM Trucks 2500 use?
A 2017 RAM Trucks 2500 can use 17-inch, 18-inch, or 20-inch rims, depending on the tire size and sub-model. The supported tire sizes pair with those wheel diameters as follows: 245/70R17 and 285/70R17 on 17-inch rims, 275/70R18 on 18-inch rims, and 285/60R20 on 20-inch rims.
That means rim diameter has to be confirmed before any replacement tire is chosen. Reading the sidewall size on the current tire and checking the wheel itself can prevent ordering the right tire size for the wrong wheel package, especially on trims that offered more than one setup.
Do all 2017 RAM Trucks 2500 sub-models use the same tire size?
No, the 2017 RAM Trucks 2500 does not use one universal tire size across all sub-models. Big Horn, Laramie, Laramie Longhorn, and SLT can use either 275/70R18 or 285/60R20, the Limited uses 285/60R20, the Power Wagon uses 285/70R17, and the Tradesman can use 245/70R17 or 275/70R18.
That variation matters because tire choice is tied to both trim and wheel diameter. Even within the same model year, two 2500 trucks parked side by side may require different sizes, so the safest approach is to verify the exact sub-model and the wheels currently on the truck.
Choosing the Right Tire
What should I consider when choosing a 2017 RAM Trucks 2500 tire?
Start with the correct size for the truck's trim and wheel diameter, since the 2017 RAM Trucks 2500 spans four different primary sizes. From there, compare construction details that matter within the correct size, such as load-capacity version, rim-width range, and whether the tire matches the truck's intended work, towing, or off-road use.
Product selection also benefits from looking at the tire's overall character rather than size alone. A truck that sees regular hauling or rough-surface use may call for a different emphasis than one used mostly for general road driving, and wheel compatibility should still be checked before finalizing any choice.
What sidewall styles are available for 2017 RAM Trucks 2500 tires?
The available products for the supported 2017 RAM Trucks 2500 sizes shown here use RWL sidewalls, which means raised white letter styling. That gives the truck a more assertive, truck-oriented presentation than a plain blackwall and is a familiar look for all-terrain applications.
Sidewall appearance should still be considered alongside fitment and use, not ahead of them. The right size and wheel match come first, and then the sidewall treatment becomes part of the visual decision, especially if the truck is being kept close to a particular period of ownership or style.
What brands offer tires for the 2017 RAM Trucks 2500?
BFGoodrich is the brand represented across the currently available 2017 RAM Trucks 2500 products in these supported sizes. The featured tires are centered on the All-Terrain T/A KO2 line, including options for 245/70R17, 275/70R18, and 285/70R17 fitments.
That makes comparison less about brand switching and more about selecting the correct size, load-capacity version, and wheel compatibility within the BFGoodrich lineup. On a truck like the 2500, those details can matter more than the badge on the sidewall when matching the tire to the vehicle's setup.
Restoration & Appearance
Which tire should I choose for a period-style 2017 RAM Trucks 2500?
A period-style choice for a 2017 RAM Trucks 2500 starts with keeping the truck in its correct original size category for the trim and wheel package already on it. Since these fitments are all radial and the visible product line centers on BFGoodrich All-Terrain T/A KO2, the period-style question is more about preserving the truck's factory-era stance than chasing an older tire construction.
Appearance should follow fitment, not replace it. Matching the existing 17-, 18-, or 20-inch setup helps maintain the truck's intended proportions, and the final visual decision can then focus on whether the all-terrain look and raised white letter sidewall suit the way the truck is being presented.
How does tire construction affect the appearance of a restored 2017 RAM Trucks 2500?
On a 2017 RAM Trucks 2500, construction changes are not a bias-ply-versus-radial debate because the primary fitments are radial. The visual difference comes more from tire size, sidewall profile, wheel diameter, and sidewall treatment than from switching between vintage construction types.
That means a restoration-oriented or preservation-minded owner should pay close attention to keeping the truck in the right 17-, 18-, or 20-inch fitment family for its trim. The wrong wheel-and-tire combination can change the truck's look more dramatically than the choice between two radial tires in the correct size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 RAM Trucks 2500?
Yes, modifications can affect tire fitment on a 2017 RAM Trucks 2500 even when the tire size itself is one of the supported sizes. Aftermarket wheels, changes in wheel width or offset, suspension lifts or lowering, and body or steering components can all influence clearance and how the tire sits on the truck.
A modified truck should be checked as it actually sits, not just by trim name. Wheel diameter, rim width, tire-to-fender clearance, and steering clearance all deserve inspection before replacement, particularly on 17-inch applications where two different primary sizes appear elsewhere in the same model line.
What should I inspect before driving a 2017 RAM Trucks 2500 on new tires?
Before putting a 2017 RAM Trucks 2500 into regular use on new tires, inspect wheel condition, confirm the size matches the truck's wheel diameter, and make sure inflation is set appropriately for the tire and intended load. It also helps to verify there is no interference at full steering lock or through normal suspension movement.
A heavy-duty pickup places real demands on its tires, so it is worth checking for even bead seating, secure valve stems, and any signs of rubbing once the truck is back on the ground. A short, careful test drive can reveal vibration, pull, or clearance concerns before longer use.
How often should tires on a 2017 RAM Trucks 2500 be inspected?
Tires on a 2017 RAM Trucks 2500 should be inspected regularly, especially before towing, hauling, or taking a longer drive. Look at tread wear, sidewall condition, air pressure, and any signs of cuts, bulges, punctures, or irregular wear that could point to alignment or suspension issues.
Heavy-duty trucks can hide tire problems until they become more serious, so routine checks are part of basic ownership. Trucks that sit for stretches between uses also deserve extra attention, since low pressure, weather exposure, and unnoticed damage can affect road readiness even when tread depth still looks acceptable.
