The 2022 Rivian Trucks R1S arrived as a modern electric SUV with serious off-road intent, three-row utility, and the kind of curb presence that makes wheel and tire choice part of the vehicle’s character. Because this is such a new-platform vehicle, the first tire question is less about vintage-style construction and more about confirming the exact wheel package on the truck. The 2022 Rivian Trucks R1S uses radial tires in three primary sizes: 275/65R20, 275/55R21, and 275/50R22. That makes wheel diameter central to the decision, especially when balancing all-terrain use, factory-style appearance, and everyday road manners.
Which Tire Size Is Right for The 2022 Rivian Trucks R1S
The 2022 Rivian Trucks R1S uses three primary tire sizes, and the right one depends first on the wheel diameter currently on the vehicle. All three are radial metric sizes, but they are tied to different 20-inch, 21-inch, and 22-inch wheel setups, so confirming the actual wheel package matters before comparing tread style, road use, or replacement options.
A 275/50R22 tire is a metric radial size with a 275-millimeter section width, a 50-series aspect ratio, and fitment for a 22-inch wheel. On the 2022 Rivian Trucks R1S, this size represents the largest rim-diameter setup among the primary fitments and keeps the focus on matching the vehicle’s existing wheel package. The lower-profile format gives this size a different visual character from the 20-inch and 21-inch alternatives, even though the section width remains the same. It is the size to evaluate when the R1S already wears 22-inch wheels and the replacement decision starts with wheel confirmation.
A 275/55R21 tire is a metric radial with a 275-millimeter section width, a 55-series profile, and a 21-inch rim diameter. For the 2022 Rivian Trucks R1S, this size sits between the 20-inch and 22-inch fitments, so it should be viewed as its own wheel-specific setup rather than as a simple variation of the others. The shared 275 width means the tire family stays consistent in section width while the sidewall profile changes with wheel diameter. This is the size to pursue when the vehicle is already equipped with 21-inch wheels and the goal is staying within that original wheel format.
A 275/65R20 tire is a metric radial size with a 275-millimeter section width, a 65-series profile, and fitment for a 20-inch wheel. On the 2022 Rivian Trucks R1S, it is the 20-inch primary fitment and is represented here by the BFGoodrich All-Terrain T/A KO2, an all-terrain radial with an RBL sidewall and a 7.5 to 9.5 inch rim-width range. Compared with the other primary sizes, this fitment carries the most off-road-oriented product character in the available selection. It deserves a closer look when the R1S has 20-inch wheels and the intended use includes rougher surfaces or a more rugged visual presentation.
Tire fitment is straightforward across the covered 2022 Rivian Trucks R1S sub-models because Adventure and Launch Edition both use the same three primary tire sizes. The key step is confirming which wheel diameter is actually on the vehicle rather than separating one sub-model from another.

2022 Rivian Trucks R1S Adventure
The 2022 Rivian Trucks R1S Adventure can use 275/50R22, 275/55R21, or 275/65R20 radial tires depending on its wheel package. Tire selection starts with confirming whether the SUV has 20-inch, 21-inch, or 22-inch wheels, then narrowing the choice by tread style and intended use.
The 2022 Rivian Trucks R1S Launch Edition follows the same fitment pattern, with 275/50R22, 275/55R21, and 275/65R20 all used on different wheel setups. That means replacement planning is centered on the actual wheel diameter on the vehicle, not on the Launch Edition name alone.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

These FAQs focus on the fitment questions that matter most for a 2022 Rivian Trucks R1S, including wheel-specific tire sizing, radial construction, available product choices, and the checks worth making before regular road use or trail duty.
Tire Size & Fitment
What tire size fits a 2022 Rivian Trucks R1S?
The 2022 Rivian Trucks R1S uses three primary tire sizes: 275/65R20, 275/55R21, and 275/50R22. All three are radial sizes, and each one matches a different wheel diameter, so there is not one universal size for every R1S.
The practical next step is to confirm the wheel diameter currently on the vehicle before choosing a replacement tire. A 20-inch wheel takes 275/65R20, a 21-inch wheel takes 275/55R21, and a 22-inch wheel takes 275/50R22, so the correct fitment starts with the actual wheel package rather than the model name alone.
What size rim does a 2022 Rivian Trucks R1S use?
The 2022 Rivian Trucks R1S uses 20-inch, 21-inch, and 22-inch rim diameters, depending on the tire and wheel package on the vehicle. Those rim diameters correspond to 275/65R20, 275/55R21, and 275/50R22 tire sizes.
Checking the wheel itself is important because two R1S vehicles can share the same year and sub-model yet still wear different rim diameters. Before replacing tires, verify the wheel marking or measure the wheel, then compare that diameter with the tire size already installed so the new tire matches the wheel correctly.
Do all 2022 Rivian Trucks R1S sub-models use the same tire size?
Adventure and Launch Edition versions of the 2022 Rivian Trucks R1S share the same overall fitment pattern, with 275/65R20, 275/55R21, and 275/50R22 all used across the covered sub-models. The sub-model alone does not narrow the tire size to one option.
That means the real fitment check is the wheel package currently on the SUV. Looking only at the badge is not enough, especially if wheels were changed after delivery, so the safest approach is to confirm the tire size on the vehicle and verify that it matches the wheel diameter before selecting a replacement.
Choosing the Right Tire
What should I consider when choosing a 275/65R20 tire for a 2022 Rivian Trucks R1S?
A 275/65R20 tire for the 2022 Rivian Trucks R1S should first match the vehicle’s 20-inch wheel setup. From there, the main considerations are construction, intended road or trail use, rim-width compatibility, and whether the tire’s load specification suits how the vehicle is driven and loaded.
The available 275/65R20 product shown here is the BFGoodrich All-Terrain T/A KO2 radial with an RBL sidewall and a 7.5 to 9.5 inch rim-width range. That makes it useful for buyers comparing a more rugged all-terrain style against the wheel width already on the R1S and the kind of use the vehicle actually sees.
What brands offer tires for the 2022 Rivian Trucks R1S?
BFGoodrich is represented in the available product selection for the 2022 Rivian Trucks R1S, specifically in the 275/65R20 size. The product offered in that fitment is the All-Terrain T/A KO2 radial, which gives the 20-inch setup an off-road-oriented replacement option.
Brand choice should still come after confirming the correct tire size and wheel diameter on the vehicle. Since the current selection shown here is tied to the 20-inch package, an R1S running 21-inch or 22-inch wheels needs the tire size matched first, then the buyer can compare the options available within that specific fitment.
What sidewall styles are available for 2022 Rivian Trucks R1S tires?
The available 275/65R20 product for the 2022 Rivian Trucks R1S uses an RBL sidewall. That gives the 20-inch all-terrain fitment a restrained, utility-focused appearance rather than a whitewall, raised white letter, or stripe-style presentation.
Sidewall style matters because it changes the visual character of the R1S even when the tire size remains correct. Once wheel diameter and tire size are confirmed, the sidewall treatment becomes part of the final decision, especially for owners trying to balance a clean modern look with a more trail-ready tire design.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Rivian Trucks R1S?
Modifications can affect tire fitment on a 2022 Rivian Trucks R1S, especially if the vehicle has aftermarket wheels, a non-standard offset, suspension changes, or body modifications. Even when the tire size looks close on paper, wheel width, wheel diameter, and clearance at steering lock still need to be checked.
That matters even more on a vehicle with multiple factory wheel diameters like the R1S. A tire that suits one wheel package may not suit another, so any change in wheels or ride height should be reviewed for fender clearance, suspension clearance, and load suitability before putting the vehicle back into regular use.
What should I inspect before driving a 2022 Rivian Trucks R1S on new tires?
Before driving a 2022 Rivian Trucks R1S on new tires, inspect tire pressure, wheel fastener torque, visible sidewall condition, and tread seating across all four corners. It also helps to confirm that the tire size matches the wheel diameter and that there is no contact with suspension components or bodywork.
A short initial road check is worthwhile after installation. Listen for rubbing, watch for steering pull or vibration, and recheck pressures once the tires have settled into service, especially on an R1S that may see a mix of highway travel, cargo use, and rough-surface driving.
How often should tires on a 2022 Rivian Trucks R1S be inspected?
Tires on a 2022 Rivian Trucks R1S should be inspected regularly, not just when tread looks worn. Frequent visual checks for cuts, punctures, sidewall damage, uneven wear, and air loss are smart practice, particularly on a heavy SUV that may alternate between pavement and off-road conditions.
Inspection is especially important after trail use, pothole impacts, or wheel changes. A quick routine of checking pressures, tread condition, and any new rubbing marks can catch fitment or wear problems early, which helps preserve tire life and keeps the vehicle ready for normal driving and longer trips.
