2013 RAM Trucks 3500 SLT Tires

The 2013 RAM Trucks 3500 SLT uses 235/80R17, 275/70R18, or 285/60R20 tires, depending on the exact sub-model. Dual rear wheel versions use 235/80R17, regular cab single-rear-wheel versions use 275/70R18, and some Crew Cab and Mega Cab trucks use either 275/70R18 or 285/60R20.

That means the correct starting point is the truck's exact configuration, not the model name alone. Verify whether it is 4x2 or 4x4, DRW or single rear wheel, and whether it carries 17-inch, 18-inch, or 20-inch wheels before replacing a full set or even one tire.

A 2013 RAM Trucks 3500 SLT can use 17-inch, 18-inch, or 20-inch rims, depending on the tire size fitted to the truck. The 235/80R17 size uses a 17-inch rim, 275/70R18 uses an 18-inch rim, and 285/60R20 uses a 20-inch rim.

Wheel diameter is the first thing to confirm because these tire sizes are not interchangeable across different rim diameters. Checking the current wheel size on the truck is especially important on used heavy-duty pickups, where aftermarket wheels or trim-level changes may have altered the original setup.

The 2013 RAM Trucks 3500 SLT covers several body and wheel configurations, so tire fitment changes with the sub-model. Dual rear wheel trucks use a different size from single-rear-wheel versions, and some Crew Cab and Mega Cab models can be equipped with either 18-inch or 20-inch wheel packages.

That variation is normal for a heavy-duty pickup with multiple cab styles and working roles. The practical takeaway is to identify the exact sub-model and physically confirm wheel diameter before choosing tires, especially if the truck has been modified or if only part of the existing set is being replaced.

Start with the correct size for the truck's exact sub-model: 235/80R17, 275/70R18, or 285/60R20. After size is confirmed, compare construction, tread type, sidewall treatment, rim-width compatibility, load capacity, and how the truck is actually used for towing, hauling, highway driving, or mixed-surface travel.

A 3500 SLT often works harder than a light-duty pickup, so the wrong size or wheel match can create more problems than the wrong tread preference. It also helps to compare the existing tire setup across all positions so replacement does not leave the truck with mismatched diameters, wheel sizes, or use characteristics.

The available sidewall styles in the covered products include RBL on the 235/80R17 BFGoodrich All-Terrain T/A KO2 and RWL on the 275/70R18 version. Those markings describe the visual sidewall treatment rather than a change in the truck's core fitment requirements.

Sidewall appearance can matter on a heavy-duty truck because it changes the overall look without changing the required size. Once the correct tire size is established, sidewall style becomes a secondary choice based on whether the truck is used as a work pickup, a cleaner street-driven truck, or a mixed-use build.

The covered product selection for the 2013 RAM Trucks 3500 SLT includes BFGoodrich. In the sizes shown here, the available tires are from the All-Terrain T/A KO2 line, giving this truck an all-terrain radial option in both 17-inch and 18-inch fitments.

Brand choice only matters after the correct size and wheel package are pinned down. On a 3500 SLT, it also makes sense to compare the product's load figure, approved rim-width range, and tread character so the tire suits the truck's real job instead of being chosen on name recognition alone.

Yes, correct tire fitment still matters on a 2013 RAM Trucks 3500 SLT, even though it is newer than a traditional collector truck. The right size preserves the intended relationship between wheel diameter, tire profile, and the truck's stance, while the wrong size can change both appearance and practical usability.

A restoration-minded owner should begin with the truck's exact sub-model and wheel package, then decide whether the goal is stock-style presentation or a more personalized look. That approach helps avoid a finished truck that looks visually off because the tire sidewall height or wheel diameter no longer matches the setup.

On the 2013 RAM Trucks 3500 SLT, the primary fitments are radial, so the appearance difference is less about bias-ply versus radial and more about the exact size and sidewall treatment selected. A 17-inch DRW tire presents differently from an 18-inch or 20-inch single-rear-wheel setup, even within the same model line.

Sidewall details such as RBL or raised white letter styling can also shift the truck's visual character. For a restoration-oriented result, the cleaner path is to match the tire to the truck's proper wheel diameter first, then decide whether the sidewall should look more understated or more overtly truck-performance inspired.

Yes, modifications can affect tire fitment on a 2013 RAM Trucks 3500 SLT. Aftermarket wheels, suspension changes, leveling kits, lowering, and body alterations can all change the space available for the tire and may also alter the wheel width or diameter needed for a proper match.

A truck that now wears different wheels from its original setup should be checked carefully before ordering replacement tires in the same size shown on the sidewall. Measuring actual wheel diameter and width, then checking steering and body clearance, is a smarter approach than assuming the current combination is automatically correct.

Before road use, inspect wheel condition, lug hardware, valve stems, tire pressure, and the overall age and condition of any remaining tires that will stay on the truck. It also helps to look for suspension wear, alignment issues, and any signs of rubbing that may have been hidden by the old tires.

A heavy-duty pickup puts real demands on its tires, especially when towing or carrying weight, so early checks matter. After installation, confirm that all positions match the intended setup and watch for vibration, pull, unusual wear, or clearance issues during the first miles instead of waiting for a longer trip.

Tires on a 2013 RAM Trucks 3500 SLT should be inspected regularly, not just at replacement time. Pressure, tread wear, cuts, punctures, sidewall damage, and irregular wear patterns are all worth checking often, particularly on a truck that tows, hauls, sits for long periods, or sees rougher surfaces.

Frequent visual inspections help catch slow air loss or uneven wear before they become expensive or inconvenient problems. A truck used intermittently can age its tires without wearing them out, so condition matters as much as tread depth, especially before highway travel, seasonal use, or putting the truck back into work duty.
