2026 RAM Trucks Tire Fitment Guide

2026 RAM Trucks vehicles use nine sizes across the 1500, 2500, and 3500 model range: 275/55R20, 275/65R18, 285/45R22, 325/65R18, 275/70R18, 285/60R20, 285/70R17, 245/70R17, and 235/80R17. The 1500 uses 275/55R20, 275/65R18, 285/45R22, 325/65R18, and 275/70R18. The 2500 uses 275/70R18, 285/60R20, 285/70R17, and 245/70R17, while the 3500 uses 275/70R18, 235/80R17, and 285/60R20.

That spread means year and make alone are not enough for a correct tire choice. Start by identifying whether your truck is a 1500, 2500, or 3500, then confirm whether it has 17-, 18-, 20-, or 22-inch wheels. Rim-width guidance is available for the sizes that currently have matching products, and those widths should be checked against the actual wheel before moving ahead.

On a 2026 RAM Trucks tire, 275/70R18 means the tire is 275 millimeters wide, the sidewall height is 70 percent of that width, the R identifies radial construction, and the tire fits an 18-inch wheel. Among 2026 RAM Trucks models, 275/70R18 is the one size shared by the 1500, 2500, and 3500, making it the broadest crossover size in the lineup.

Understanding that code helps prevent two common mistakes: confusing section width with wheel diameter, and assuming another 18-inch truck tire will interchange just because the rim size matches. Even when two tires mount on the same diameter wheel, section width, profile, and load marking still matter. For a 2026 RAM Trucks owner, the code should always be matched to the exact sidewall and wheel already on the truck.

No, 2026 RAM Trucks models do not all use the same tire size. The 1500 has five sizes of its own, the 2500 has four, and the 3500 has three, with only 275/70R18 shared across all three model lines. The heavy-duty 2500 and 3500 also share 285/60R20, while several other sizes are unique to one model family only.

That means a tire search should begin with the model designation on the truck rather than with RAM branding alone. A 1500 owner looking at a 22-inch fitment, for example, is in a different part of the range than a 3500 owner using a 17-inch work-oriented size. Once the model is confirmed, compare the tire's full sidewall code to the truck's existing setup before making a final choice.

2026 RAM Trucks tires in the currently covered sizes come with either RWL or RBL sidewall styling. 275/65R18, 275/70R18, 285/70R17, and 245/70R17 are available with raised white letters, while 235/80R17 is available with a raised black letter sidewall. All of them are modern radial truck tires rather than vintage-style reproductions.

Sidewall style changes the look of a truck more than many buyers expect, especially on full-size pickups with open wheel arches and visible tire sidewalls. Raised white letters lean toward a more traditional off-road and sport-truck appearance, while raised black letters are more subdued. If appearance matters as much as size, choose the correct tire only after confirming whether you want the sidewall to stand out or blend in.

BFGoodrich covers the currently available 2026 RAM Trucks sizes here, including 275/65R18, 275/70R18, 285/70R17, 245/70R17, and 235/80R17. The series represented is the All-Terrain T/A KO2, a radial truck tire aimed at pickup and SUV use. Coverage is concentrated in the 17- and 18-inch truck sizes rather than the entire 2026 RAM wheel range.

For a buyer, that means brand choice may be less about comparing several manufacturers and more about confirming whether your exact RAM size falls into the product-supported part of the lineup. Once the size matches, the next questions become sidewall style, load rating, speed rating, and wheel-width compatibility. Those details matter more in practice than the badge on the sidewall alone.

The two 285/70R17 choices for 2026 RAM Trucks are both BFGoodrich All-Terrain T/A KO2 radials with RWL sidewalls, but they differ in load and speed markings. One carries a 116Q rating with a 2,755-pound maximum load at 50 psi and weighs 50.3 pounds. The other carries a 121/118R rating with a 3,195-pound maximum load at 80 psi and weighs 58.2 pounds.

That difference makes the sidewall code especially important on a 2500 using this size. The Q-rated version is lighter and carries a lower load figure, while the R-rated version is built for a heavier load at a higher pressure. Before choosing between them, compare the truck's existing tire placard, wheel rating, and intended duty so the tire's service description aligns with how the truck is actually used.

Several 2026 RAM Trucks sizes have clear rim-width guidance. 275/65R18 fits rims from 7.5 to 9.5 inches wide, 275/70R18 fits 7.0 to 9.0 inches, 285/70R17 fits 7.5 to 9.5 inches, 245/70R17 fits 6.5 to 8.0 inches, and 235/80R17 fits 6.0 to 7.5 inches. Those width ranges are tied to the specific sizes rather than to RAM trucks as a whole.

Rim width matters because it affects section shape, tread profile, and the way the tire seats on the wheel. Even when the wheel diameter is correct, a wheel that is too narrow or too wide can change how the tire performs and wears. Measure or verify the actual wheel before choosing a replacement, especially on used trucks where wheels may have been changed from the original setup.

The 2026 RAM Trucks sizes covered here are modern radial truck tires, and none of the sidewall markings here identify them as tube-type products. Their fitment and construction are consistent with tubeless radial applications on the correct wheels. That said, tube use should always match the wheel design and the exact product's sidewall marking rather than being assumed from size alone.

For most late-model RAM applications, the more important setup check is wheel condition, bead-seat integrity, and valve-stem health. If a truck has aftermarket wheels, older service parts, or a wheel repair history, verify that the wheel is suitable for tubeless service before mounting new tires. That is especially worthwhile on trucks used for towing or carrying heavier loads, where air retention is critical.

A 2026 RAM Trucks should be stored on clean, properly inflated tires away from direct sunlight, standing moisture, and ozone sources such as electric motors, welders, and battery chargers. Modern radial tires generally tolerate storage better than old bias-ply designs, but long periods of inactivity can still create flat spotting, pressure loss, and sidewall aging if the truck sits in one position for too long.

Move the truck periodically if possible, or support it in a way that reduces sustained load when it will sit for an extended season. Keep the tires clean, avoid petroleum-based dressings, and check pressures before the truck goes into storage and again before it returns to service. A heavy-duty 2500 or 3500 benefits especially from stable storage practices because static load is higher.

Tires on a 2026 RAM Trucks should be judged by age and condition as much as by tread depth. A good rule is to begin close inspection around five to seven years of service and to treat about ten years from the DOT date code as a strong replacement threshold, even if the truck has low mileage. That guidance is especially relevant for trucks used seasonally or kept as secondary vehicles.

A tire can look serviceable at a glance yet still age out through internal degradation, hardening, or weather checking. Owners who tow, haul, or spend time at highway speeds should be even more conservative because heat and load accelerate tire stress. If the truck's use is irregular, write down the installation date and check the DOT code so age never becomes an afterthought.

Tires on a 2026 RAM Trucks should be inspected before every drive and again before any longer highway trip or towing run. Look for cuts, bulges, punctures, irregular wear, pressure loss, and sidewall cracking, and pay attention to whether the truck has been sitting long enough to develop temporary flat spots. Uneven wear can also point to alignment, suspension, or inflation issues rather than a tire defect.

A quick walkaround catches problems early and is especially worthwhile on full-size pickups that may alternate between unloaded commuting and heavier-duty service. Check the spare at the same time, since an aged or underinflated spare is a common weak point. If the truck has recently changed wheels, had suspension work, or spent time off-road, inspect even more carefully before putting miles on it.

Yes, 2026 RAM Trucks tires in these covered sizes are modern radial truck tires suitable for highway use when size, load rating, speed rating, inflation, and wheel compatibility are all correct. The speed ratings here include Q at 99 mph, R at 106 mph, and S at 112 mph depending on size and product. Those ceilings are well above normal U.S. highway speeds, but they do not override the truck's own load, towing, and condition limits.

For real-world safety, the more important questions are whether the tire's service description matches the truck's duty, whether pressure is correct, and whether the suspension and brakes are in sound condition. A 1500 used mainly on-road and a 3500 carrying heavier loads ask different things from a tire. Match the sidewall rating to the truck's actual use rather than assuming any tire in the right diameter is enough.

Inflation pressure on 2026 RAM Trucks tires depends on the exact size and product. Current examples include 275/65R18 at 3,415 pounds max load at 80 psi, 275/70R18 at 3,640 pounds at 80 psi, 285/70R17 in one version at 2,755 pounds at 50 psi and another at 3,195 pounds at 80 psi, 245/70R17 at 3,000 pounds at 80 psi, and 235/80R17 at 3,085 pounds at 80 psi. Those figures are tire ratings, not universal truck settings.

Use the truck's door-jamb or owner's manual guidance for the baseline vehicle recommendation, then confirm that the tire's own pressure and load capacity are appropriate for the service it will see. Never transfer one size's pressure to another just because both fit a RAM truck. When replacing only part of a set or changing wheel packages, pressure discipline becomes even more important.

Before a longer drive in a 2026 RAM Trucks, inspect all tires for cracking, punctures, cuts, exposed cords, bulges, and irregular wear, then confirm cold inflation pressures with an accurate gauge. Check that the tire size and service description match the truck's intended use, especially if it will tow or carry a heavier load. The spare should also be inspected for age, pressure, and overall condition.

A long-trip check should go beyond tires alone, because late-model trucks still depend on brakes, steering, suspension, and wheel hardware being in proper condition. If the truck has sat for a while, drive a short test loop first and listen for vibration or pull that could point to flat spotting or low pressure. Catching those issues before the main trip is easier than troubleshooting them on the roadside.
