The 2023 Rivian Trucks R1T brought all-electric capability into the pickup world with a blend of adventure-focused design, quick acceleration, and genuine off-road intent. Owners tend to approach it less like a conventional half-ton and more like a highly specialized truck built around range, traction, and terrain versatility. Tire fitment reflects that broad mission, with the R1T using three primary radial sizes: 275/50R22, 275/55R21, and 275/65R20. That means the real decision is not just size, but wheel diameter, road-versus-trail emphasis, and the visual stance you want to preserve. Before choosing a replacement, confirm which wheel package is on the truck and match the tire to how the R1T is actually used.
Which Tire Size Is Right for The 2023 Rivian Trucks R1T
The 2023 Rivian Trucks R1T uses three primary tire sizes, and the right one depends first on wheel diameter. These are all radial fitments, but they are tied to 22-inch, 21-inch, and 20-inch wheel setups rather than being interchangeable choices on the same rim. Before selecting a tire, confirm which wheel package is on the truck, then compare the available options within that exact size for intended road use, appearance, and wheel compatibility.
A 275/50R22 tire uses a 275-millimeter section width, a 50-series aspect ratio, radial construction, and a 22-inch rim diameter. On the 2023 Rivian Trucks R1T, this size represents the largest wheel fitment of the three primary setups and is part of the truck's modern metric radial sizing strategy. The low-profile format gives this size a distinctly contemporary look compared with the smaller-rim alternatives. Choosing 275/50R22 starts with confirming that the truck is actually equipped with 22-inch wheels, since rim diameter determines fitment before any other tire comparison does.
A 275/55R21 tire keeps the same 275-millimeter section width, uses radial construction, and fits a 21-inch rim, with the 55-series profile sitting between the other two R1T sizes. For the 2023 Rivian Trucks R1T, this size occupies the middle ground in wheel diameter and sidewall proportion within the factory-style fitment range. Its sizing format is straightforward for modern buyers, but the key point is that it is still specific to a 21-inch wheel package. Select this size only after verifying the actual wheel diameter on the truck and checking any tire replacement against the intended driving mix.
A 275/65R20 tire combines a 275-millimeter section width with a taller 65-series sidewall, radial construction, and a 20-inch rim diameter. On the 2023 Rivian Trucks R1T, this is the most substantial sidewall profile among the three primary sizes, and it is the size with an available BFGoodrich All-Terrain T/A KO2 option in an RBL sidewall treatment. The available product also brings its own rim-width and load specifications into the decision. This size is the one to evaluate when the truck wears 20-inch wheels and the goal leans toward a more trail-oriented replacement tire.
The covered R1T sub-model fitment is straightforward, but tire choice still depends on the exact wheel package on the truck. The Adventure trim can use all three primary sizes, so wheel diameter matters more than trim name when it is time to replace tires.

Best 2023 Rivian Trucks R1T Tires for Sale
Current product coverage centers on 275/65R20, where the BFGoodrich All-Terrain T/A KO2 provides a radial all-terrain option with an RBL sidewall and defined rim-width compatibility. For R1T owners on 20-inch wheels, the product grid is mainly about matching that size to intended use and wheel setup.
These FAQs focus on the 2023 Rivian Trucks R1T's three tire sizes, wheel-diameter-dependent fitment, radial tire selection, appearance choices, and the checks that matter before road or trail use.
Tire Size & Fitment
What tire size fits a 2023 Rivian Trucks R1T?
The 2023 Rivian Trucks R1T uses three primary tire sizes: 275/50R22, 275/55R21, and 275/65R20. All three are radial sizes, and each one corresponds to a different wheel diameter rather than representing interchangeable options on the same rim.
The practical next step is to confirm which wheels are actually on the truck before shopping for tires. An R1T with 22-inch wheels needs the 22-inch size, a 21-inch setup needs the 21-inch size, and a 20-inch setup needs the 20-inch size. That wheel check matters more than trim name because the Adventure sub-model can use all three sizes.
What size rim does a 2023 Rivian Trucks R1T use?
A 2023 Rivian Trucks R1T can use 20-inch, 21-inch, or 22-inch rims, depending on the wheel and tire package installed on the truck. The matching tire sizes are 275/65R20, 275/55R21, and 275/50R22, all in radial construction.
Rim diameter is the first fitment point to verify because it determines which tire size family applies. Checking the sidewall marking on the current tire is usually the quickest confirmation. Once the wheel diameter is known, compare replacement tires within that exact size and then review wheel width, clearance, and intended use before making a final selection.
Do all 2023 Rivian Trucks R1T sub-models use the same tire size?
No. The covered 2023 Rivian Trucks R1T Adventure sub-model can use more than one tire size: 275/50R22, 275/55R21, or 275/65R20. The variation comes from the wheel package on the truck, not from a change in basic tire construction, since all three are radial fitments.
That means trim alone does not answer the tire question. Two R1T Adventure trucks can need different replacement tires if they were equipped with different wheel diameters. Before replacing anything, check the tire sidewall or measure the wheel to confirm whether the truck has a 20-, 21-, or 22-inch setup, then choose within that exact size.
Choosing the Right Tire
What should I consider when choosing a 275/65R20 tire for a 2023 Rivian Trucks R1T?
Start with the basics: the truck must actually be on 20-inch wheels, and the tire must be 275/65R20. From there, compare the tire's construction, load specification, rim-width compatibility, sidewall style, and intended use. In this size, an available option is the BFGoodrich All-Terrain T/A KO2 with an RBL sidewall.
The available 275/65R20 product carries a 3,750-pound maximum load capacity at 80 psi and a recommended rim-width range of 7.5 to 9.5 inches. Those details matter because a tire can be the right nominal size yet still need review against the actual wheel and how the R1T is used, especially if the truck sees more trail work or carries added gear.
What sidewall styles are available for 2023 Rivian Trucks R1T tires?
Among the currently covered R1T tire products, the available sidewall style is RBL in 275/65R20. That gives the buyer a more utility-oriented sidewall presentation rather than a whitewall, redline, or raised white letter look.
Sidewall style affects appearance more than basic fitment, so it becomes a useful comparison point once the correct size is confirmed. On a modern truck like the R1T, many owners use sidewall treatment to support either a cleaner road-focused look or a more rugged all-terrain presentation. The main priority is still matching the tire to the wheel diameter and tire size already on the truck.
What brands offer tires for the 2023 Rivian Trucks R1T?
Current covered product availability for the 2023 Rivian Trucks R1T includes BFGoodrich in 275/65R20. The available tire is part of the All-Terrain T/A KO2 line and is built as a radial all-terrain option for the 20-inch wheel setup.
Brand is only one part of the decision. Once the correct size is confirmed, compare the tire's series, sidewall styling, rim-width requirement, load capacity, and overall use case. That matters on the R1T because three different primary sizes exist, and the right tire choice begins with the truck's actual wheel diameter before moving on to brand preference.
Restoration & Appearance
How does tire construction affect the appearance of a 2023 Rivian Trucks R1T?
On the 2023 Rivian Trucks R1T, construction is straightforward because the primary fitments are radial across all three sizes. Appearance is influenced more by the wheel diameter and sidewall proportion than by a bias-ply versus radial choice, since the R1T's tire options stay within modern radial sizing.
That makes 275/50R22 look noticeably different from 275/65R20 even though both are correct within their respective wheel packages. The 22-inch setup gives the truck a lower-profile, more contemporary stance, while the 20-inch size carries more sidewall and a more rugged visual balance. Preserving the truck's intended look starts with staying with the correct wheel-and-tire combination.
Does correct tire fitment matter for the appearance of a 2023 Rivian Trucks R1T?
Yes. On a 2023 Rivian Trucks R1T, correct tire fitment has a major effect on the truck's stance, sidewall shape, and overall visual balance. Because the R1T uses three distinct sizes tied to 20-inch, 21-inch, or 22-inch wheels, the wrong tire size can quickly alter the look of the truck.
Appearance and fitment are closely linked here. A taller sidewall on the 20-inch setup gives a different profile than the 21-inch or 22-inch arrangements, and sidewall treatment adds another layer of visual character. Even when the goal is mostly appearance, wheel diameter, tire size marking, and wheel-width compatibility should still be verified before mounting a replacement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Rivian Trucks R1T?
Yes. A 2023 Rivian Trucks R1T with aftermarket wheels, suspension changes, or body modifications can have different tire-clearance needs than a truck on its original setup. Even when the tire size matches one of the R1T's primary fitments, changes in wheel width, offset, or ride height can affect the result.
That is why the safest approach is to verify the actual wheel diameter first, then review wheel width and available clearance at full steering lock and suspension travel. A modified R1T may still use one of the standard sizes, but fitment should be checked against the truck as it sits now rather than assumed from model year alone.
What should I inspect before driving a 2023 Rivian Trucks R1T on new tires?
Before putting serious miles on new tires, inspect the 2023 Rivian Trucks R1T for correct tire size, proper inflation, secure wheel installation, and clearances at the fender, suspension, and steering components. It also helps to confirm that all four tires match the intended wheel package and that no sidewall or tread damage occurred during mounting.
A short road test can reveal vibration, rubbing, or handling changes before a longer trip. Recheck inflation after the tires have settled and keep an eye on uneven wear during the first several drives. On a truck with multiple possible wheel diameters, that early inspection is especially useful because it confirms the replacement tires truly match the installed wheels.
How often should tires on a 2023 Rivian Trucks R1T be inspected?
Tires on a 2023 Rivian Trucks R1T should be inspected regularly, not just when tread looks worn. A quick visual check before longer drives is a good habit, and a closer inspection should include tread condition, cuts, punctures, sidewall damage, and signs of air loss.
The truck's weight, torque, and mixed-use potential make routine checks worthwhile even when mileage is low. Look for uneven wear that could point to alignment, inflation, or suspension issues, and confirm that all tires remain the same size and construction intended for the wheel package. Periodic inspection becomes even more important after off-road use or wheel and suspension changes.
