Rivian Trucks R1S Tires

Rivian Trucks R1S uses four tire sizes in this range: 275/50R22 for 2022 through 2026, 275/55R21 for 2022 through 2024, 275/65R20 for 2022 through 2025, and 275/60R20 for 2025 through 2026. Those sizes correspond to three wheel diameters across the model line: 22-inch, 21-inch, and 20-inch, with two different 20-inch fitments appearing depending on year and configuration.

The practical takeaway is that year alone is not enough for every Rivian Trucks R1S. Start by checking the tire sidewall already on the vehicle and confirming the wheel diameter, then match that to the year listing. That matters most in 2025, when both 275/65R20 and 275/60R20 appear on 20-inch wheels, and in the earlier years where 20-, 21-, and 22-inch packages all exist.

On a Rivian Trucks R1S, 275/50R22 is a modern metric radial tire size. The 275 is the section width in millimeters, 50 is the aspect ratio as a percentage of that width, R means radial construction, and 22 is the wheel diameter in inches. The same decoding logic applies to the other R1S sizes in this range, including 275/55R21, 275/65R20, and 275/60R20.

Understanding the code helps you avoid choosing a tire that shares the same width but not the same wheel diameter or sidewall height. Rivian Trucks R1S uses more than one wheel package, so the final number in the size is the first check, and the middle number matters when comparing the two different 20-inch options that appear across these years.

A 2025 Rivian Trucks R1S can show three sizes because that model year spans multiple wheel-package configurations. The listed sizes are 275/50R22, 275/65R20, and 275/60R20, which means the split is driven by wheel diameter first and then by a second 20-inch specification within the same year. That is not unusual on a modern SUV offered with different intended uses and appearance packages.

For a 2025 Rivian Trucks R1S, the best way to narrow the correct fitment is to verify the wheel diameter on the vehicle and then compare the exact size on the current sidewall. If the vehicle has 20-inch wheels, do not assume both 20-inch sizes interchange just because the rim diameter matches. The aspect ratio difference changes overall tire dimensions and should be matched to the vehicle’s specific configuration.

Rivian Trucks R1S uses 20-inch, 21-inch, and 22-inch wheel diameters across the years listed here. The 20-inch fits are tied to 275/65R20 from 2022 through 2025 and 275/60R20 from 2025 through 2026, the 21-inch fit is 275/55R21 from 2022 through 2024, and the 22-inch fit is 275/50R22 from 2022 through 2026.

That spread means the wheel diameter must be confirmed before anything else, especially on used Rivian Trucks R1S vehicles where wheels may have been changed or swapped between trims. Once the wheel diameter is known, the correct tire choices become much narrower. The second step is confirming the full size code, since 2025 includes two different 20-inch options rather than one.

A 2025 Rivian Trucks R1S can use 275/50R22, 275/65R20, or 275/60R20, so the exact wheel package must be confirmed on the vehicle. Start with the tire sidewall and wheel diameter, because the 22-inch package is easy to separate from the 20-inch options. If the vehicle has 20-inch wheels, the remaining choice is between the 65-series and 60-series tire.

The safest approach is to verify the current size against the vehicle’s original specification materials or a Rivian specialist, especially if the wheels or tires may have been changed previously. Matching only the width and rim diameter is not enough on a Rivian Trucks R1S. The aspect ratio changes overall tire height, which can affect appearance, calibration, and intended use.

Within the available products listed here for Rivian Trucks R1S, BFGoodrich is the brand currently represented. The listed product is the BFG All-Terrain T/A KO2 in size 275/65R20, with radial construction and a 20-inch rim diameter. That means the current product coverage shown here is focused on one of the 20-inch R1S fitments rather than the full size range.

If your Rivian Trucks R1S uses 275/65R20, that BFGoodrich option aligns with an all-terrain style tire and includes a published rim-width range of 7.5 to 9.5 inches. If your R1S carries 21-inch or 22-inch wheels, or the later 275/60R20 fitment, the first step is confirming the exact size on the vehicle before comparing alternatives within the appropriate wheel package.

The available series listed here for Rivian Trucks R1S is All Terrain T/A KO2. That series is paired with radial construction in size 275/65R20 and is positioned as an all-terrain type tire rather than a period-style collector application. No additional series families are listed in the current product set for the other R1S sizes.

For a Rivian Trucks R1S owner, that means the key comparison on this page is less about multiple classic series options and more about matching the exact installed size and wheel diameter first. Once the fitment is confirmed, the next consideration is whether the vehicle’s use leans more toward road driving or mixed-surface use. On the listed 275/65R20 fitment, the KO2 points toward the latter.

A Rivian Trucks R1S should be stored on a clean, dry surface away from prolonged sun exposure, ozone sources, and extreme temperature swings. Tires age more gracefully when they are kept out of direct UV light and away from electric motors, compressors, and other equipment that can accelerate rubber degradation. Maintaining proper inflation during storage also helps prevent flat spotting and sidewall stress.

If a Rivian Trucks R1S will sit for extended periods, move it periodically or use storage practices that reduce concentrated load on one section of the tire. Check inflation before and after storage rather than assuming the tires held pressure. Since R1S models can use several wheel and tire packages, keep a record of the exact fitted size so rotation, replacement, and future service stay consistent.

Tires on a Rivian Trucks R1S should be visually inspected regularly and checked closely before any longer drive. Look for irregular wear, cuts, punctures, sidewall damage, embedded debris, and signs that one corner of the vehicle is wearing differently than the others. Inflation pressure should also be verified at routine intervals, since underinflation and overinflation both change wear patterns and ride behavior.

Frequent inspection matters on a Rivian Trucks R1S because the model uses different wheel diameters and, in some years, different sidewall heights even on the same rim diameter. A mismatch or wear issue is easier to catch early when you know the exact size fitted to the vehicle. Make inspection part of regular garage time rather than waiting for visible tread loss or a trip interruption.

A Rivian Trucks R1S tire should be replaced when age, cracking, structural damage, repeated pressure loss, impact injury, or abnormal wear suggests the casing is no longer trustworthy, even if the tread still looks usable. Tread depth is only one part of tire condition. Heat cycles, storage history, and service use can all age a tire beyond what the surface appearance alone suggests.

For an R1S that sees intermittent use, age can become the deciding factor before tread wear does. Have the tires evaluated whenever there is visible sidewall checking, vibration that cannot be balanced out, or evidence of uneven wear related to alignment or suspension issues. Replacing as a matched set on the correct wheel diameter and exact size helps preserve consistent ride and handling characteristics.

A tire that matches the correct Rivian Trucks R1S size, wheel diameter, and intended use can be appropriate for public-road driving, but only when the tire is in sound condition and properly fitted. The listed available product is a radial BFGoodrich All-Terrain T/A KO2 in 275/65R20, with a published maximum load capacity of 3,750 pounds at 80 psi. Safety depends on selecting the exact fitment the vehicle requires rather than a near match.

Before road use, confirm that the tire size on the vehicle matches one of the approved R1S sizes for that year and wheel package. Then inspect condition, inflation, and wear pattern, and make sure all four tires are compatible with each other. A Rivian Trucks R1S is heavy and capable, so using the wrong size or a damaged tire creates a larger penalty in stability and braking than on a lighter vehicle.

Before driving a Rivian Trucks R1S, check inflation pressure, visible tire condition, tread wear, and the exact size installed on the vehicle. Also verify that the wheel diameter and tire size agree, especially if the vehicle was acquired used or has seen seasonal wheel swaps. On the listed 275/65R20 option, published fitment details include a 20-inch rim diameter and a 7.5 to 9.5 inch rim-width range.

That pre-drive check is especially valuable on a Rivian Trucks R1S because some years carry three possible sizes and 2025 includes two different 20-inch tires. A quick sidewall inspection can prevent running the wrong replacement on one axle or discovering a damage issue after the vehicle is already on the road. Consistency across all four positions matters for stability systems and predictable handling.

A Rivian Trucks R1S should be driven at speeds appropriate to the exact tire fitted, its condition, inflation, and load, rather than by a blanket assumption tied only to the model name. The listed 275/65R20 BFGoodrich tire carries a 126S service description, and that rating should be respected together with the tire’s condition and the vehicle’s operating load. Speed capability is never separate from maintenance and proper fitment.

In practical terms, a Rivian Trucks R1S owner should treat the sidewall markings on the installed tire as the governing reference and avoid pushing aged, damaged, or unevenly worn tires at highway pace. If the vehicle has recently changed wheel packages or tire sizes, re-check that the exact fitted tire matches the intended configuration. A correctly matched set in good condition is the foundation for safe road-speed use.
