2025 RAM Trucks continues the brand’s modern full-size pickup identity with a lineup that ranges from the lighter-duty 1500 to the heavy-duty 2500 and 3500. For buyers using these trucks for everyday driving, towing, work, or off-road travel, tire selection matters because the lineup spans multiple wheel diameters and several distinct metric radial sizes rather than one universal fitment. Across three models, nine tire sizes appear, with only 275/70R18 shared across the full range and several other sizes tied to specific trucks. The first thing to confirm on a 2025 RAM Trucks vehicle is the exact model, then the wheel diameter already on the truck, before narrowing the tire choice.
Which Tire Size Is Right for Your 2025 RAM Trucks
Nine tire sizes are used across 2025 RAM Trucks vehicles, and they vary by model rather than carrying across the entire lineup. Because these sizes span 17-inch, 18-inch, 20-inch, and 22-inch rims, the real decision starts with confirming the exact model and wheel diameter already on the truck. Understanding that distinction before choosing a product saves time and helps match the tire to the correct RAM application.
Year(s): 2025|Fit(s): 1500|Construction: Radial|Rim: 18 in
275/65R18 is a metric radial size with a 275-millimeter section width, a 65-series aspect ratio, and an 18-inch rim diameter. This 1500-specific size is available from BFGoodrich with an RWL sidewall and an R speed rating, which carries a 106 mph ceiling. It suits owners who want an 18-inch radial fitment matched to the 1500 and prefer an all-terrain style with a raised white letter appearance.
Year(s): 2025|Fit(s): 1500|Construction: Radial|Rim: 20-in rim
275/55R20 is a metric radial size that uses a 275-millimeter section width, a 55-series aspect ratio, and a 20-inch rim diameter. It is specific to the 2025 RAM Trucks 1500. This size belongs with 1500 trucks already equipped for 20-inch fitment rather than serving as a year-wide RAM size.
Year(s): 2025|Fit(s): 1500|Construction: Radial|Rim: 22-in rim
285/45R22 is a metric radial size with a 285-millimeter section width, a 45-series aspect ratio, and a 22-inch rim diameter. It is used only on the 2025 RAM Trucks 1500. This size is the most wheel-diameter-specific fitment in the 2025 RAM Trucks range, so confirming that the truck actually carries 22-inch wheels is essential before moving further.
Year(s): 2025|Fit(s): 1500|Construction: Radial|Rim: 18-in rim
325/65R18 is a metric radial size with a 325-millimeter section width, a 65-series aspect ratio, and an 18-inch rim diameter. It is specific to certain 2025 RAM Trucks 1500 applications rather than being shared with the heavy-duty models. This is the widest size in the year-and-make range, so it is best approached as a model-specific 1500 fitment that should be matched carefully to the truck’s existing wheel setup.
Year(s): 2025|Fit(s): 1500, 2500, 3500|Construction: Radial|Rim: 18 in
275/70R18 is a metric radial size with a 275-millimeter section width, a 70-series aspect ratio, and an 18-inch rim diameter. It is available from BFGoodrich with an RWL sidewall and an R speed rating, which carries a 106 mph ceiling. Because this is the only size shared by the 1500, 2500, and 3500, it is the broadest cross-model fitment in the 2025 RAM Trucks lineup.
Year(s): 2025|Fit(s): 2500, 3500|Construction: Radial|Rim: 20-in rim
285/60R20 is a metric radial size that combines a 285-millimeter section width, a 60-series aspect ratio, and a 20-inch rim diameter. This size is specific to 2025 RAM Trucks 2500 and 3500 models rather than the lighter-duty 1500. It belongs with heavy-duty trucks already on 20-inch wheels, so buyers should verify whether they have a 2500 or 3500 before treating it as interchangeable with other RAM sizes.
Year(s): 2025|Fit(s): 2500|Construction: Radial|Rim: 17 in
285/70R17 is a metric radial size with a 285-millimeter section width, a 70-series aspect ratio, and a 17-inch rim diameter. This 2500-specific size is available from BFGoodrich with an RWL sidewall, and speed rating varies by product: Q carries a 99 mph ceiling, while R carries a 106 mph ceiling. It is a useful size to compare carefully within the same series because the available versions differ in load and speed character even though both fit the same 17-inch application.
Year(s): 2025|Fit(s): 2500|Construction: Radial|Rim: 17 in
245/70R17 is a metric radial size with a 245-millimeter section width, a 70-series aspect ratio, and a 17-inch rim diameter. This 2500-specific size is available from BFGoodrich with an RWL sidewall and an S speed rating, which carries a 112 mph ceiling. It suits 2500 applications that call for a narrower 17-inch fitment than the 285/70R17.
Year(s): 2025|Fit(s): 3500|Construction: Radial|Rim: 17 in
235/80R17 is a metric radial size with a 235-millimeter section width, an 80-series aspect ratio, and a 17-inch rim diameter. This 3500-specific size is available from BFGoodrich with an RBL sidewall and an S speed rating, which carries a 112 mph ceiling. It is the narrowest size used across 2025 RAM Trucks and is tied specifically to the 3500 rather than shared across the broader model range.
Three 2025 RAM Trucks model lines are covered here: the 1500, 2500, and 3500. Tire size varies by model, so year and make alone are not enough to identify the right fitment; the truck’s series and wheel diameter matter first. Select a model below to narrow the fitment history and see the tire options that apply to that specific RAM truck.
2025 RAM Trucks 1500
The 2025 RAM Trucks 1500 is the light-duty member of the lineup, aimed at buyers who want pickup capability with more everyday comfort and broad trim variety. Its tires mount on 18-inch, 20-inch, or 22-inch wheels depending on configuration, which gives the 1500 the widest spread of fitments in the RAM family for this model year.
The 2025 RAM Trucks 2500 sits in the heavy-duty middle ground, balancing work-truck capability with the broader usability many owners want for towing, hauling, and mixed road conditions. Its tires mount on 17-inch, 18-inch, or 20-inch wheels, and the available sizes reflect that blend of heavy-duty function and configuration-specific wheel packages.
The 2025 RAM Trucks 3500 is the heaviest-duty pickup in the range, built for buyers who prioritize serious hauling and towing capacity over lighter-duty comfort priorities. Its tires mount on 17-inch, 18-inch, or 20-inch wheels, with fitments that stay distinct from the 1500 and overlap only partly with the 2500.
Six products are available across nine tire sizes for 2025 RAM Trucks vehicles. 275/65R18, 275/70R18, 245/70R17, and 235/80R17 each have one BFGoodrich radial all-terrain option with RWL or RBL sidewall styling, while 285/70R17 has two BFGoodrich radial options with RWL sidewalls and varying speed ratings.
These FAQs focus on how tire sizes change across the 2025 RAM Trucks 1500, 2500, and 3500, what the metric size codes mean, and what to confirm about rim width, sidewall style, load capacity, and long-term truck use before choosing a tire.
Size Basics & Fitment
What tire sizes fit 2025 RAM Trucks vehicles?
2025 RAM Trucks vehicles use nine sizes across the 1500, 2500, and 3500: 275/65R18, 275/55R20, 285/45R22, 325/65R18, 275/70R18, 285/60R20, 285/70R17, 245/70R17, and 235/80R17. The 1500 uses 275/65R18, 275/55R20, 285/45R22, 325/65R18, and 275/70R18; the 2500 uses 275/70R18, 285/60R20, 285/70R17, and 245/70R17; and the 3500 uses 275/70R18, 235/80R17, and 285/60R20. Rim diameters span 17, 18, 20, and 22 inches, so there is no single year-wide fitment.
That spread means buyers should identify the truck series first, then verify the wheel diameter already on the truck before narrowing to a tire. Where rim-width guidance exists, 275/65R18 fits 7.5 to 9.5-inch rims, 275/70R18 fits 7.0 to 9.0, 285/70R17 fits 7.5 to 9.5, 245/70R17 fits 6.5 to 8.0, and 235/80R17 fits 6.0 to 7.5. If your truck has been changed from factory wheel size, the wheel itself matters as much as the badge on the fender.
What does 275/70R18 mean on a 2025 RAM Trucks tire?
On a 2025 RAM Trucks tire, 275/70R18 means the tire is 275 millimeters wide, uses a 70-series aspect ratio, and mounts on an 18-inch wheel. The R in the size code means radial construction. Within the 2025 RAM Trucks lineup, 275/70R18 is especially important because it is the one size shared by the 1500, 2500, and 3500.
That does not make 275/70R18 a universal substitute for every 2025 RAM Trucks fitment, because several other model-specific sizes use different wheel diameters. It does mean that an 18-inch-equipped truck from any of the three RAM series may point you toward this size, so it is often the first one to compare when you are verifying an existing wheel-and-tire setup or replacing tires on a truck with factory 18-inch wheels.
Do all 2025 RAM Trucks models use the same tire size?
No. Only 275/70R18 is shared across all 2025 RAM Trucks model lines. The 1500 also uses 275/65R18, 275/55R20, 285/45R22, and 325/65R18; the 2500 adds 285/60R20, 285/70R17, and 245/70R17; and the 3500 adds 285/60R20 and 235/80R17.
In practical terms, that means a buyer cannot stop at year and make alone. A 1500 owner may be choosing among 18-, 20-, or 22-inch wheel fitments, while a 2500 or 3500 owner may be working with 17-, 18-, or 20-inch fitments tied to heavier-duty use. If the truck is new to you, confirm the series and read the size molded into the current tire sidewall before assuming another RAM size will interchange.
Buying the Right Tire
What sidewall styles are available for 2025 RAM Trucks tires?
2025 RAM Trucks tires here appear with two sidewall treatments: RWL and RBL. BFGoodrich 275/65R18, 275/70R18, 285/70R17, and 245/70R17 use RWL, while 235/80R17 uses RBL. All of these are radial truck tires, but the sidewall presentation changes the look noticeably even when the construction type stays the same.
For a buyer who cares about appearance, raised white letters give a more aggressive, off-road-oriented look that fits many modern truck builds, while black-letter styling reads cleaner and more understated. Sidewall style does not override basic fitment, so wheel diameter, model series, and the exact size still come first. Once those are confirmed, sidewall treatment becomes a useful final filter for matching the truck’s intended look.
What brands make tires for 2025 RAM Trucks vehicles?
BFGoodrich covers the available 2025 RAM Trucks products here, centered on the All-Terrain T/A KO2 line. BFGoodrich appears in 275/65R18, 275/70R18, 285/70R17, 245/70R17, and 235/80R17, all in radial construction. That gives current coverage across several of the 17-inch and 18-inch RAM applications, with a heavy all-terrain character.
For many RAM owners, that means the brand choice is straightforward and the real comparison happens within size, load, sidewall style, and speed rating rather than between multiple manufacturers. If your truck uses one of the uncovered year-and-make sizes, start by confirming the exact wheel and sidewall size on the truck. If it uses one of the covered sizes, compare the tire’s load and speed details against how the truck is actually used.
What is the difference between the two 285/70R17 tires for 2025 RAM Trucks?
The two 285/70R17 tires for 2025 RAM Trucks are both BFGoodrich All-Terrain T/A KO2 radials with RWL sidewalls, but they differ in load and speed specification. One carries a 116Q rating with a 2,755-pound maximum load at 50 psi and a 99 mph speed ceiling. The other carries a 121/118R rating with a 3,195-pound maximum load at 80 psi and a 106 mph speed ceiling. Both fit the same 17-inch rim diameter and the same 7.5 to 9.5-inch rim-width range.
That makes the decision less about brand or tread family and more about matching the tire’s rating to the truck’s duty cycle. A buyer using a 2025 RAM Trucks 2500 for heavier payload or towing will want to pay close attention to the higher-load version, while a lighter-use truck may not need that specification. The sidewall size alone is not enough; the service description and pressure/load pairing matter too.
Fitting & Setup
What rim width do 2025 RAM Trucks tires require?
Several 2025 RAM Trucks sizes have clear rim-width guidance. 275/65R18 fits 7.5 to 9.5-inch rims, 275/70R18 fits 7.0 to 9.0-inch rims, 285/70R17 fits 7.5 to 9.5-inch rims, 245/70R17 fits 6.5 to 8.0-inch rims, and 235/80R17 fits 6.0 to 7.5-inch rims. Those ranges are tied to the specific tire size and should not be transferred from one RAM size to another.
Rim width affects sidewall shape, tread contact behavior, and how correctly the tire seats on the wheel. Even if two sizes share the same rim diameter, that does not mean they want the same wheel width. Before choosing a replacement tire for a 2025 RAM Trucks vehicle, confirm both the sidewall size and the actual wheel dimensions already on the truck, especially if aftermarket wheels have been installed.
Do 2025 RAM Trucks tires require inner tubes?
The available 2025 RAM Trucks products here are modern radial truck tires, and none of the covered size markings use tube-type notation. Sizes such as 275/65R18, 275/70R18, 285/70R17, 245/70R17, and 235/80R17 appear as contemporary radial fitments rather than vintage tube-type constructions. On that basis, these fitments are approached as tubeless-style truck tire applications.
The important follow-up is to verify the wheel itself. A tubeless tire still depends on a sound wheel, clean bead seats, and a correct valve stem. If a 2025 RAM Trucks wheel has been damaged, heavily corroded, or replaced with a nonstandard wheel, sealing and service requirements can change. The safest habit is to inspect the specific tire sidewall marking and confirm wheel condition before mounting or replacing any tire.
Maintenance, Storage & Longevity
How should I store a 2025 RAM Trucks when the tires are fitted?
A 2025 RAM Trucks vehicle stored on its tires should be kept in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Tire pressure should be maintained during storage, and the truck should be rolled periodically so the same section of tread is not carrying the load for months at a time. Clean, dry surfaces are better than bare dirt or areas that hold moisture.
Even though these are modern radial truck tires rather than older bias-ply designs, collector-style storage habits still matter. Long static storage, low pressure, and environmental exposure age tires even when tread looks fresh. If a 2025 RAM Trucks vehicle sits for extended stretches, some owners use stands to reduce load on the tires, but that should be done with the chassis supported correctly and the suspension considered as part of the storage plan.
How long do tires on a 2025 RAM Trucks typically last?
Tires on a 2025 RAM Trucks vehicle should be evaluated by age as well as tread wear. A practical collector and specialty-use guideline is to begin close inspection around five to seven years and to treat roughly ten years as a strong replacement consideration, even if the tires still show usable tread. The DOT date code on the sidewall is the best way to identify age.
That matters because many trucks accumulate fewer miles than the tread pattern might suggest, especially second vehicles, tow rigs, or recreational builds. Rubber hardens, sidewalls can crack, and internal structure ages with time, heat cycles, and storage conditions. A 2025 RAM Trucks owner who drives only occasionally should not assume low mileage means a tire is still serviceable; age and condition deserve equal weight.
How often should tires on a 2025 RAM Trucks be inspected?
Tires on a 2025 RAM Trucks vehicle deserve a quick inspection before every drive and a more deliberate inspection before towing, hauling, or any longer trip. Check for sidewall cracking, cuts, bulges, punctures, irregular tread wear, and pressure loss. It is also wise to look at valve stems and to inspect the spare, because a neglected spare often becomes the weak link on an otherwise well-prepared truck.
Regular inspection is especially important on trucks that alternate between daily use and long idle periods. Load-carrying vehicles place more stress on tires than lightly used passenger cars, and a 2500 or 3500 can expose a marginal tire quickly when payload or trailer weight enters the picture. Catching a pressure issue or sidewall defect in the garage is far easier than discovering it after the truck is already loaded.
Safety & Road Use
Are 2025 RAM Trucks tires safe for highway driving?
The available 2025 RAM Trucks products here are modern radial truck tires with speed ratings that include Q, R, and S. Q corresponds to 99 mph, R corresponds to 106 mph, and S corresponds to 112 mph. Those ceilings are well above normal U.S. highway speeds, so for everyday road use the condition of the tire, the correct inflation pressure, and the truck’s overall mechanical state matter at least as much as the speed letter itself.
Highway safety is never only a tire question on a pickup. Load, trailer tongue weight, suspension condition, alignment, brake condition, and the age of the tire all influence how confidently a 2025 RAM Trucks vehicle will behave at speed. A healthy radial tire with the correct load rating is a strong starting point, but it should be matched to the truck’s real duty and inspected as part of a full road-readiness check.
What inflation pressure should I use for 2025 RAM Trucks tires?
Inflation pressure on 2025 RAM Trucks tires should follow the truck manufacturer’s recommendation for the specific model and use, while the tire’s own maximum-pressure marking defines the upper limit tied to its rated load. Available examples include 275/65R18 at 3,415 pounds @ 80 psi, 275/70R18 at 3,640 pounds @ 80 psi, 285/70R17 at either 2,755 pounds @ 50 psi or 3,195 pounds @ 80 psi, 245/70R17 at 3,000 pounds @ 80 psi, and 235/80R17 at 3,085 pounds @ 80 psi.
Those figures should not be used as a blanket pressure recommendation across the entire 2025 RAM Trucks range. A 1500 used as a commuter, a 2500 carrying tools, and a 3500 towing regularly may all want different operating pressures even when tire construction is similar. The right approach is to start with the truck’s door-jamb or owner’s-manual guidance, then make sure the chosen tire’s ratings support the truck’s intended load.
What should I check before taking a 2025 RAM Trucks on a longer drive?
Before a longer drive in a 2025 RAM Trucks vehicle, inspect every tire for cracking, cuts, punctures, bulges, uneven wear, and correct cold inflation pressure. Confirm that the spare is usable, the valve stems are in good condition, and the tread has not worn unevenly from alignment or suspension issues. On trucks that tow or haul, it is also worth checking for signs of past overload stress such as shoulder wear or heat-related hardening.
A longer trip is also the right time to think beyond the tires themselves. Wheel torque, brake condition, fluid levels, trailer setup, and steering or suspension play all affect how securely the truck will travel. Tires are the part touching the road, but a 2025 RAM Trucks vehicle is only as roadworthy as the rest of the system around them. A careful pre-trip inspection helps prevent surprises after the miles start adding up.
