2020 RAM Trucks 1500 Tires

The 2020 RAM Trucks 1500 uses four primary tire sizes: 275/65R18, 275/70R18, 275/55R20, and 285/45R22. All four are radial sizes, but they do not apply across the entire model range equally, because trim and wheel package determine which one belongs on a specific truck.

The important next step is confirming the exact sub-model and the actual wheel diameter on the truck. A Rebel follows a different fitment path than a Limited or Big Horn, and some trims were offered with more than one size, so checking the wheel before ordering avoids crossing 18-inch, 20-inch, and 22-inch applications.

A 2020 RAM Trucks 1500 can use 18-inch, 20-inch, or 22-inch rims depending on sub-model and tire size. The 275/65R18 and 275/70R18 sizes use 18-inch rims, 275/55R20 uses a 20-inch rim, and 285/45R22 uses a 22-inch rim.

That makes wheel confirmation the most important fitment check before selecting tires. Looking only at the truck model name is not enough, because several trims were available with multiple wheel packages. Matching the tire to the installed rim diameter should come before comparing tread style, sidewall appearance, or brand.

The 2020 RAM Trucks 1500 has more than one tire size because the model range spans different trims, wheel packages, and intended uses. Some versions use practical 18-inch or 20-inch fitments, while others step up to a 22-inch setup, and the Rebel uses its own 275/70R18 size.

That variation means tire selection starts with configuration, not just year and model. A truck with factory-style 22-inch wheels needs a completely different tire than one on 18-inch wheels, and a changed wheel package can alter fitment again. Verifying the exact sub-model and measuring the current wheel setup keeps the search accurate.

Start with the correct tire size for the exact 2020 RAM Trucks 1500 sub-model and wheel diameter, since this truck can use 18-inch, 20-inch, or 22-inch fitments. Construction is straightforward because the primary sizes on this page are all radial, so the main variables become size, wheel compatibility, and intended use.

After size is confirmed, compare tire character against how the truck is driven. A buyer may prioritize all-terrain capability, sidewall appearance, load capacity, or rim-width compatibility depending on the application. Trucks used for highway driving, mixed-duty use, or a more aggressive stance often call for different priorities even within the correct fitment.

Among the available products shown for this 2020 RAM Trucks 1500 fitment, the sidewall style is RWL, or raised white letter. That style appears on the BFGoodrich All-Terrain T/A KO2 options offered in the covered 18-inch sizes, giving the truck a more traditional off-road and light-truck presentation.

Sidewall style is mainly an appearance decision once the correct tire size has been confirmed. It can change the truck’s visual character noticeably, especially on a Rebel or other 18-inch setup, but it should still be balanced against size, rim-width compatibility, and how the tire will actually be used on the road or trail.

The available products shown here for applicable 2020 RAM Trucks 1500 fitments come from BFGoodrich. The covered 18-inch sizes, 275/65R18 and 275/70R18, are represented by the All-Terrain T/A KO2 series in radial construction with raised white letter sidewalls.

Brand matters most after the truck’s exact tire size is settled, since several RAM 1500 trims use different wheel diameters. It also helps to compare the rest of the specification, including rim-width range and load capacity, rather than focusing on brand name alone. That keeps the selection tied to the truck’s real fitment and use.

On the 2020 RAM Trucks 1500, the primary fitments on this page are all radial, so construction change is not the appearance issue it can be on older collector vehicles. The visual effect comes more from size, wheel diameter, and sidewall treatment, especially when comparing an 18-inch all-terrain look with larger 20-inch or 22-inch wheel packages.

That means appearance-focused buyers should pay close attention to the truck’s existing wheel setup and the style of tire being considered. A raised white letter all-terrain tire presents the truck very differently than a lower-profile street-oriented fitment, even when both are correct for different RAM 1500 configurations.

Yes, correct tire fitment matters if the goal is to keep a 2020 RAM Trucks 1500 looking true to its original configuration. Because this truck was offered with several wheel and tire combinations, the right visual result depends on matching the correct size to the actual trim and wheel package rather than choosing by appearance alone.

A factory-style presentation starts with the proper 18-inch, 20-inch, or 22-inch fitment, then moves to details such as sidewall style and tire character. Trucks that have been modified with aftermarket wheels or suspension changes may no longer reflect their original setup, so checking what is physically on the vehicle is an important first step.

Yes, modifications can affect tire fitment on a 2020 RAM Trucks 1500 even when the tire size matches a known factory application. Aftermarket wheels, offset changes, leveling kits, lowering, suspension changes, or body modifications can alter clearance and may change which tire size works properly on the truck.

That is especially important on a model range that already spans 18-inch, 20-inch, and 22-inch fitments. A truck that left the factory with one setup may now carry a different wheel package altogether. Measuring the installed wheel diameter and width, then checking clearance at full steering lock and suspension travel, helps avoid surprises.

Before driving a 2020 RAM Trucks 1500 on new tires, inspect the wheels for the correct diameter and sound condition, confirm that the tires are inflated properly, and look over the suspension and steering components for obvious wear or looseness. Lug torque and general wheel mounting condition also deserve attention before road use.

A short initial drive should include listening for rubbing and checking that the truck tracks normally through turns and over bumps. It also helps to recheck pressure and visually inspect the sidewalls after the first miles. Those simple steps are useful on any RAM 1500, especially one with recent wheel changes or mixed-use duty.

Before a longer drive, check tread condition, inflation pressure, visible damage, and any signs of air loss on the tires fitted to the 2020 RAM Trucks 1500. It is also wise to look for sidewall cuts, bulges, uneven wear, or cracking, since trucks can sit for periods and still appear fine at a glance.

Longer trips also make it worthwhile to verify that the spare, if carried, is serviceable and properly inflated. A truck used for towing, hauling, or rougher secondary roads benefits from an extra look at wheel condition and suspension health as well. Catching a pressure or wear issue early is far easier than dealing with it on the road.
