The 2023 Rivian Trucks R1S brings electric SUV capability into a segment that still asks a lot from its tires, whether the goal is daily road use, long-distance travel, or mixed-surface driving. Its combination of weight, torque, and large-diameter wheel packages makes fitment choice more than a cosmetic decision. This R1S uses radial tires in three different primary sizes: 275/65R20, 275/55R21, and 275/50R22. That gives owners a clear split between wheel diameters and tire profiles rather than one universal setup. The right choice starts with confirming the exact wheel package on the vehicle and then matching the tire to intended use, appearance, and clearance needs.
Which Tire Size Is Right for The 2023 Rivian Trucks R1S
The 2023 Rivian Trucks R1S uses three primary tire sizes, and the correct one depends first on wheel diameter. These sizes are all radial fitments, but they are tied to different 20-inch, 21-inch, and 22-inch wheel setups rather than interchangeable versions of the same tire. Before choosing a replacement, confirm which wheel package is actually on the vehicle, then compare tire construction, intended use, and any clearance considerations if the R1S has been modified.
275/50R22 is a metric radial size in which 275 identifies the nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 22 is the wheel diameter in inches. On the 2023 Rivian Trucks R1S, this size is part of the larger-wheel fitment path and pairs a lower-profile sidewall with a 22-inch rim. The format will be familiar to modern SUV owners, even though the wheel diameter makes it more specialized than a common replacement size. Use this size when the R1S is equipped with the matching 22-inch wheels and keep wheel and suspension changes in mind before replacing tires.
275/55R21 follows the same modern metric radial format, with a 275-millimeter nominal width, a 55-series profile, radial construction, and a 21-inch rim diameter. For the 2023 Rivian Trucks R1S, this size serves as a distinct primary fitment tied to a 21-inch wheel package rather than an alternate description of another tire. Its dimensions place it between the 20-inch and 22-inch setups in profile and wheel size. This is the size to evaluate when the vehicle carries 21-inch wheels, and replacement selection should begin with wheel confirmation before comparing tire type or intended road use.
275/65R20 is a metric radial tire size that uses a 275-millimeter nominal section width, a 65-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2023 Rivian Trucks R1S, it represents the 20-inch wheel fitment and carries a taller sidewall than the 21-inch and 22-inch alternatives. Available choices in this size include the BFGoodrich All-Terrain T/A KO2 with an RBL sidewall and a 7.5- to 9.5-inch rim-width range. This size is the right place to focus when the R1S has 20-inch wheels and the owner wants a replacement matched to that wheel package and intended use.
Fitment is straightforward across the covered 2023 Rivian Trucks R1S sub-models because both use the same three primary tire sizes. The key step is still confirming the actual wheel diameter on the vehicle, since 20-inch, 21-inch, and 22-inch setups each require their own tire size.

2023 Rivian Trucks R1S Adventure
The 2023 Rivian Trucks R1S Adventure uses the same three radial tire sizes found across the broader R1S fitment range. Tire selection comes down to confirming whether the vehicle has 20-inch, 21-inch, or 22-inch wheels and then choosing a replacement that matches intended road or mixed-use driving.
The 2023 Rivian Trucks R1S Launch Edition also uses the same three radial tire sizes as the other covered R1S sub-model. That means the main fitment decision is not trim level but the wheel package currently on the vehicle, especially if wheels or tires have been changed since delivery.
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.

Tire Size & Fitment
What tire size fits a 2023 Rivian Trucks R1S?
The 2023 Rivian Trucks R1S uses three primary tire sizes: 275/65R20, 275/55R21, and 275/50R22. All three are radial fitments, and each one corresponds to a different wheel diameter rather than a universal one-size-fits-all setup for every R1S on the road.
The most important step is confirming whether the vehicle has 20-inch, 21-inch, or 22-inch wheels before ordering tires. A replacement should match the wheel diameter first, then be checked for wheel width, clearance, and intended use, especially if the R1S has aftermarket wheels, suspension changes, or a different tire setup than it left with.
What size rim does a 2023 Rivian Trucks R1S use?
A 2023 Rivian Trucks R1S can use 20-inch, 21-inch, or 22-inch rims, depending on which tire size is on the vehicle. The corresponding tire sizes are 275/65R20 for 20-inch wheels, 275/55R21 for 21-inch wheels, and 275/50R22 for 22-inch wheels.
Rim diameter should be verified at the wheel itself, not assumed from trim level alone. Once the wheel diameter is confirmed, it also helps to check wheel width and any changes in wheel offset, since those factors can affect clearance, steering behavior, and which replacement tires are appropriate for the R1S's current setup.
Do all 2023 Rivian Trucks R1S sub-models use the same tire size?
The covered 2023 Rivian Trucks R1S sub-models share the same three primary tire sizes. Both the Adventure and Launch Edition can use 275/65R20, 275/55R21, or 275/50R22, all in radial construction.
That means tire choice is driven more by the wheel package on the individual vehicle than by sub-model name. An owner should confirm the wheel diameter currently installed and avoid assuming that every Adventure or Launch Edition still has its original wheel-and-tire combination, especially if the vehicle has already seen upgrades or replacements.
Choosing the Right Tire
What should I consider when choosing a tire for a 2023 Rivian Trucks R1S?
Start with the correct size for the wheel package on the vehicle: 275/65R20, 275/55R21, or 275/50R22. From there, compare construction details, intended use, load-carrying specification, and whether the tire's character matches how the R1S is actually driven.
A road-focused replacement and an all-terrain replacement can serve very different needs even when the size is correct. It also helps to confirm wheel width, check for any modifications, and think about ride profile and clearance before choosing, since the R1S uses multiple wheel diameters and a replacement should suit the vehicle as it sits today.
What brands offer tires for the 2023 Rivian Trucks R1S?
For the current product coverage shown here, BFGoodrich is available in 275/65R20 for the 2023 Rivian Trucks R1S. The tire offered in that size is the All-Terrain T/A KO2, a radial design built around a 20-inch wheel fitment.
Brand comparison only matters after the correct wheel diameter and tire size are confirmed. Once that is settled, the real question becomes whether the available tire's construction, sidewall style, rim-width compatibility, and intended use line up with how the R1S is driven, particularly for owners balancing pavement use with rougher surfaces.
What sidewall styles are available for 2023 Rivian Trucks R1S tires?
Among the currently covered products for the 2023 Rivian Trucks R1S, the available 275/65R20 option uses an RBL sidewall. That means sidewall appearance can be part of the selection process, but the first priority remains matching the tire to the correct 20-inch, 21-inch, or 22-inch wheel setup.
Sidewall style can affect the overall look of the vehicle, especially on a modern SUV with large exposed wheel diameters. Appearance should still come after fitment basics such as size, construction, load capacity, and wheel compatibility, since an attractive sidewall treatment does not override the need for the right tire for the R1S's actual wheel package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Rivian Trucks R1S?
Yes, modifications can change what works on a 2023 Rivian Trucks R1S even when the tire size looks close on paper. Aftermarket wheels, changes in wheel offset, suspension alterations, or body changes can all affect clearance at the fenders, suspension components, and steering range.
That is especially important on a vehicle with three different factory wheel diameters and large overall tire dimensions. Any modified R1S should be checked for actual wheel size, wheel width, and available clearance before a replacement is selected, because a tire that suits one setup may create rubbing or compatibility issues on another.
What should I inspect before driving a 2023 Rivian Trucks R1S on new tires?
Before road use, confirm that the new tires match the wheel diameter and are mounted on wheels within the tire's approved width range when that specification is available. It also makes sense to inspect inflation pressure, lug torque, tread condition, sidewalls, and any signs of interference during full steering travel.
A short, careful test drive can reveal rubbing, vibration, or balance issues before the vehicle is used normally. After that initial drive, recheck pressures and look again for clearance concerns, especially if the R1S has 20-inch all-terrain tires, aftermarket wheels, or suspension changes that could alter how the tire sits in the wheelwell.
How often should tires on a 2023 Rivian Trucks R1S be inspected?
Tires on a 2023 Rivian Trucks R1S should be inspected regularly, not just when tread looks worn. A visual check for cuts, punctures, uneven wear, bulges, cracking, and pressure loss helps catch problems early, particularly on a heavy SUV that can place significant demand on its tires.
Monthly pressure checks are a smart baseline, and another inspection is worthwhile before longer trips or after driving on rough surfaces. Owners should also take a closer look any time ride quality changes, steering feels different, or a wheel or tire has been damaged, since early signs of a problem are easier to address than a roadside failure.
