RAM Trucks 3500 Tires

RAM Trucks 3500 uses three tire sizes across the 2017 through 2026 range shown here: 235/80R17 on 17-inch wheels, 275/70R18 on 18-inch wheels, and 285/60R20 on 20-inch wheels. All three sizes appear throughout the full year span, so there is not a single year break where one size replaces another for the whole model line.

That means the correct choice depends on the specific wheel package on the truck, not the year alone. Check the tire sidewall currently on the truck, confirm the wheel diameter, and compare that to the listed fitments before selecting a replacement.

A 2020 RAM Trucks 3500 can have 235/80R17, 275/70R18, or 285/60R20 because the model range uses different wheel diameters within the same year. That is a rim-diameter split, not a case where one tire fits all 2020 trucks.

The practical takeaway is that trim, wheel package, or equipment level can change the correct tire even when the model year stays the same. Treat the year as a starting point, then verify the actual wheel size on the truck before moving forward.

RAM Trucks 3500 uses three rim diameters in the range covered here: 17 inches with 235/80R17, 18 inches with 275/70R18, and 20 inches with 285/60R20. Those diameters run across the full 2017 to 2026 span rather than appearing as a simple early-versus-late production change.

Rim diameter is the non-negotiable fitment check, because a tire built for one wheel diameter cannot be installed on another. If the truck has aftermarket wheels, confirm the actual wheel measurement rather than relying only on model year assumptions.

On RAM Trucks 3500, 235/80R17 is a modern metric radial size. The 235 is the section width in millimeters, 80 is the aspect ratio, R means radial construction, and 17 is the wheel diameter in inches.

That sizing format helps you compare profile and width against the other RAM Trucks 3500 fitments on this page. A truck using 235/80R17 has a 17-inch wheel and a relatively tall sidewall, so the replacement tire needs to match both the diameter and the intended load use.

A 2022 RAM Trucks 3500 can use 235/80R17, 275/70R18, or 285/60R20, so the correct tire size is confirmed by the wheel diameter and the size already fitted to the truck. The year alone is not enough because all three sizes are used in that same model year.

Start with the size molded into the current tire sidewall, then verify that it matches the wheel diameter on the truck. If the truck has changed hands or wears aftermarket wheels, checking the wheel and existing tire together is the safest way to avoid choosing the wrong fitment.

The RAM Trucks 3500 products listed here show two sidewall styles: RWL on the 275/70R18 BFGoodrich All-Terrain T/A KO2 and RBL on the 235/80R17 BFGoodrich All-Terrain T/A KO2. RWL means raised white letters, while RBL means raised black letters.

Sidewall style affects appearance more than core fitment, but it can matter if you want the truck to keep a certain look. Once the correct tire size and wheel diameter are confirmed, sidewall style becomes a secondary choice tied to how original, understated, or aggressive you want the truck to appear.

The RAM Trucks 3500 products listed here are from BFGoodrich. The available products shown for the listed sizes are part of the All-Terrain T/A KO2 series.

Brand is only one part of the decision on a heavy-duty truck like RAM Trucks 3500. The more important checks are matching the correct size, confirming the wheel diameter, and making sure the tire's intended use suits how the truck will actually be driven and loaded.

A RAM Trucks 3500 should be stored on a clean, dry surface away from prolonged sunlight, ozone sources, and major temperature swings. Keeping the tires properly inflated during storage helps the casing hold its shape, especially on a heavy-duty truck that carries substantial vehicle weight.

If the truck sits for long periods, move it occasionally or place it so one spot on the tire is not carrying the load for months at a time. Long stationary periods can encourage flat-spotting and uneven stress, even on modern radial truck tires.

Tires on a RAM Trucks 3500 should be inspected regularly for air pressure, tread wear, cracking, punctures, and impact damage. A heavy-duty pickup places real demands on its tires, so routine checks matter whether the truck is used for towing, hauling, or occasional driving.

A practical routine is to inspect the tires before longer trips, after carrying heavy loads, and anytime the truck feels different on the road. Catching irregular wear early can also reveal alignment, suspension, or inflation issues before they shorten tire life.

Tires on a RAM Trucks 3500 should be replaced when age, cracking, weathering, bulges, puncture history, or structural concerns make them questionable, even if visible tread still looks usable. Tread depth alone is not the full measure of a tire's serviceability on a heavy-duty truck.

Collector vehicles, work trucks that sit, and lightly used tow rigs often age out tires before they wear them out. If a RAM Trucks 3500 has older tires with little tread wear but visible age-related deterioration, replacement is the more sensible path than relying on appearance alone.

A RAM Trucks 3500 can be driven on public roads when the tires are the correct size for the wheel diameter, are in sound condition, and are suitable for the truck's intended load use. The listed products here are modern radial truck tires, which are appropriate for real road use when properly matched and maintained.

Safety depends on the whole combination rather than the size code alone. Before regular road use, check inflation, tread condition, age, visible damage, and whether the truck's actual wheel diameter matches the tire fitted to it.

Before driving a RAM Trucks 3500, check tire pressure, visible sidewall condition, tread wear, and any signs of puncture or impact damage. On a heavy-duty truck, it also makes sense to verify that the tire size on the vehicle matches the wheel diameter and the truck's working role.

That pre-drive check becomes even more important if the truck tows, carries a bed load, or spends long periods parked between uses. A few minutes spent checking the tires can prevent poor handling, uneven wear, and avoidable roadside trouble.

Appropriate speed for a RAM Trucks 3500 depends on the exact tire fitted, its condition, inflation, and the truck's load at the time. Even with modern radial truck tires, heavy-duty pickups should be driven in a way that respects the tire's intended service and the added demands of towing or payload.

In practical terms, avoid treating a loaded RAM Trucks 3500 like a lightly equipped passenger vehicle. Keep speed in line with the truck's weight, cargo, road conditions, and overall condition, especially if the truck is being used for the kind of work these models were built to handle.
