2023 RAM Trucks Tire Fitment Guide

2023 RAM Trucks vehicles use 11 sizes across four pickup models: 275/55R20, 275/65R18, 285/45R22, 275/70R18, 325/65R18, 265/70R17, 275/60R20, 285/60R20, 285/70R17, 245/70R17, and 235/80R17. The 1500 uses five of those sizes, the 1500 Classic uses two, the 2500 uses four, and the 3500 uses three. Only 275/70R18 is shared across the 1500, 2500, and 3500, while 285/60R20 is shared by the 2500 and 3500.

That means year and make alone are not enough for a confident tire choice on 2023 RAM Trucks. Start by identifying whether you have a 1500, 1500 Classic, 2500, or 3500, then confirm whether your truck carries 17-, 18-, 20-, or 22-inch wheels. Once those two details are nailed down, the correct size usually becomes much easier to pinpoint.

On a 2023 RAM Trucks tire, a size such as 275/70R18 breaks down into three main dimensions plus construction. The 275 is the section width in millimeters, the 70 is the aspect ratio, meaning the sidewall height is 70 percent of the section width, the R means radial construction, and the 18 is the wheel diameter in inches. The same decoding logic applies to the other RAM sizes such as 265/70R17, 285/60R20, and 285/45R22.

Understanding that code helps you compare two RAM tires that may share a wheel diameter but differ in width or sidewall height. A 17-inch, 18-inch, 20-inch, or 22-inch tire cannot be mixed across wheel diameters, and a wider or lower-profile metric size can change the truck's stance and overall proportions. The size molded into your current tire sidewall is the fastest starting point when confirming fitment.

No, 2023 RAM Trucks models do not all use the same tire size. The 1500 alone spans five sizes, the 1500 Classic has its own two-size range, the 2500 adds four more heavy-duty fitments, and the 3500 uses three sizes with one unique 17-inch option. Even when two trucks share a size, such as 275/70R18 or 285/60R20, that does not mean every RAM pickup in the lineup does.

This matters most when a buyer knows the truck is a 2023 RAM but has not yet narrowed down the exact model or wheel package. A 1500 Classic and a 1500 are both half-ton RAM trucks, yet their size ranges are not the same. Checking the model badge, wheel diameter, and the existing sidewall marking will keep you from comparing products intended for the wrong part of the RAM family.

2023 RAM Trucks tires on this page appear in two sidewall styles: RWL and RBL. The BFGoodrich KO2 products for 275/65R18, 275/70R18, 265/70R17, 285/70R17, and 245/70R17 use raised white letters, while 235/80R17 appears with a raised black letter sidewall. Those sidewall treatments are cosmetic, but they can change the truck's overall look quite a bit.

For a modern RAM pickup, the sidewall decision usually comes down to appearance rather than authenticity in the vintage-car sense. Raised white letters suit an all-terrain, off-road-inspired look, while black-letter sidewalls read more subdued and workmanlike. If your truck already has one style and you want a consistent look, confirm the sidewall style before making the final product choice.

BFGoodrich covers the 2023 RAM Trucks sizes that currently have product coverage here, including 275/65R18, 275/70R18, 265/70R17, 285/70R17, 245/70R17, and 235/80R17. Those products are all radial all-terrain designs from the All-Terrain T/A KO2 family. The emphasis is on light-truck and heavy-duty pickup use rather than vintage-style sidewall treatments or classic bias-ply construction.

That makes brand comparison simple for the RAM sizes covered here, but size confirmation still matters because not every RAM size has the same load index, speed rating, or rim-width range. Even within the same BFGoodrich family, a 265/70R17 and a 285/70R17 are aimed at different wheel diameters and truck applications. Once the correct size is confirmed, then the product details become the deciding factor.

The two 265/70R17 BFGoodrich KO2 options for 2023 RAM Trucks 1500 Classic share the same radial construction, 17-inch rim diameter, RWL sidewall style, S speed rating, and 7.0-to-9.0-inch rim-width range. Where they differ is load capacity and inflation rating: 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 points to two distinct duty levels within the same nominal size.

For the buyer, the key is matching the tire's load range to how the truck is equipped and used rather than assuming every 265/70R17 is interchangeable in practice. A half-ton RAM used lightly may not need the heavier-duty version, while a truck that sees more cargo, towing, or firmer tire pressures may call for it. Checking the current tire's service description and the door-jamb specification is the smartest next step.

Several 2023 RAM Trucks sizes have clear rim-width ranges. The 275/65R18 fits 7.5 to 9.5 inches wide, the 275/70R18 fits 7.0 to 9.0 inches, the 265/70R17 fits 7.0 to 9.0 inches, the 285/70R17 fits 7.5 to 9.5 inches, the 245/70R17 fits 6.5 to 8.0 inches, and the 235/80R17 fits 6.0 to 7.5 inches. Those ranges apply to the tire size itself, not automatically to every wheel ever installed on a RAM truck.

That is why wheel diameter alone is only the first checkpoint. Two tires may both fit a 17-inch wheel, yet one can prefer a wider rim than another. Before choosing a product, compare your actual wheel width against the tire's approved range so the tire maintains its intended shape, load support, and road manners.

The 2023 RAM Trucks products covered here are modern radial light-truck tires, and none of the size markings indicate tube-type construction. Sizes such as 275/65R18, 275/70R18, 265/70R17, 285/70R17, 245/70R17, and 235/80R17 appear in standard radial form rather than with a tube-type designation. That points buyers toward tubeless use on the correct modern wheel.

Even so, wheel condition still matters. A bent, corroded, or damaged rim can create sealing problems regardless of whether the tire itself is tubeless. If you are reusing factory wheels on a work truck or older truck within the lineup, inspect bead seats and valve stems carefully before mounting new rubber.

A 2023 RAM Trucks pickup stores best in a cool, dry garage away from direct sunlight, electric motors, battery chargers, welders, or other ozone-producing equipment that can age rubber prematurely. Keep the tires properly inflated, avoid parking for long periods on wet ground, and move the truck periodically so one section of the tread is not carrying the load month after month. These are all radial tires, so long-term flat-spotting is usually less pronounced than with older bias-ply designs, but it can still happen.

For seasonal or collector-style use, many owners either roll the truck a short distance every few weeks or support it in a way that reduces static loading during long storage. Clean, dry sidewalls also make inspections easier when the truck comes back into service. A stored spare deserves the same protection from sun, moisture, and ozone as the four tires on the ground.

On a 2023 RAM Trucks pickup, tire age is usually a more useful guide than mileage alone, especially if the truck sees mixed seasonal use or spends long periods parked. A good rule is to begin evaluating tires closely once they reach about five to seven years of age and to treat around ten years as a serious replacement threshold regardless of remaining tread. The DOT date code on the sidewall gives the tire's week and year of manufacture.

Heavy-duty truck use can shorten practical life if the tires spend time under high loads, tow regularly, or run at sustained highway speeds in heat. By contrast, a low-mileage truck can still age out on tires that look cosmetically decent at first glance. Tread depth matters, but age cracking, hardening, and loss of flexibility are often the deciding factors on a lightly used RAM.

Tires on a 2023 RAM Trucks pickup should be inspected before every drive and again before any longer highway trip or towing run. Look for sidewall cracking, cuts, punctures, bulges, uneven tread wear, embedded debris, and any sign that a tire is losing pressure. Because these are modern radial truck tires, pressure retention and shoulder wear are especially important clues to alignment, loading, or inflation issues.

A quick walk-around takes only a minute and can catch problems before they become expensive or dangerous. For trucks that sit for stretches, include the spare in the inspection routine and verify the valve stems are in good condition. If one tire shows a wear pattern the others do not, treat that as a sign to check suspension, alignment, or loading habits rather than simply replacing one tire and moving on.

Yes, the 2023 RAM Trucks tires covered here are modern radial light-truck designs suitable for normal highway use when matched to the correct size, load range, and condition. The speed ratings visible here include S at 112 mph, R at 106 mph, and Q at 99 mph depending on size and version. Those ceilings are well above ordinary highway speeds, and on a RAM pickup the truck's load, suspension setup, braking condition, and towing demands often matter more in real-world use than outright tire speed capability.

The practical takeaway is that highway suitability depends on the whole setup being correct, not just the tire size molded into the sidewall. A 2500 or 3500 carrying weight should have a tire whose service description and inflation support that use, while a lightly used 1500 still needs healthy rubber and proper pressure. If the tires are aged, damaged, or mismatched, fix that before planning longer interstate miles.

Inflation pressure for 2023 RAM Trucks tires depends on the exact size and service description. Among the products covered here, 275/65R18 reaches 3,415 pounds at 80 psi, 275/70R18 reaches 3,640 pounds at 80 psi, 265/70R17 appears in both 50-psi and 80-psi versions, 285/70R17 also appears in both 50-psi and 80-psi versions, 245/70R17 reaches 3,000 pounds at 80 psi, and 235/80R17 reaches 3,085 pounds at 80 psi. Those figures are tire ratings, not a blanket instruction to run every truck at the maximum sidewall pressure.

Use the truck's door-jamb placard or owner's manual as the starting point for everyday inflation, then make sure the tire you choose is compatible with that application. If you are comparing two versions of the same nominal size, the service description can change the correct pressure strategy significantly. Pressure should be checked cold and adjusted for the truck's actual use, especially if towing or hauling is involved.

Before taking a 2023 RAM Trucks pickup on a longer drive, inspect each tire for cracking, cuts, punctures, bulges, uneven wear, and proper cold inflation pressure. Confirm that the tire size matches the wheel and truck, and make sure the spare is usable and inflated as well. On trucks that may tow or carry weight, also look closely for sidewall stress or shoulder wear that can suggest chronic underinflation or overload.

Tires are only one part of the preparation, but they are one of the easiest items to verify before the trip begins. A few minutes spent checking the four road tires, spare, and valve stems can prevent a roadside issue that strains the truck's brakes, suspension, or drivetrain. If anything looks questionable, resolve it before adding highway speed, heat, cargo, or trailer weight to the equation.
