2023 Rivian Trucks Tire Fitment Guide

2023 Rivian Trucks vehicles use three tire sizes: 275/50R22, 275/55R21, and 275/65R20. Both the 2023 Rivian Trucks R1S and 2023 Rivian Trucks R1T use all three sizes, and each size corresponds to a different wheel diameter: 22 inches, 21 inches, or 20 inches. For the currently shown 275/65R20 option, rim width coverage runs from 7.5 to 9.5 inches.

That means the first thing to verify on a 2023 Rivian Trucks vehicle is the wheel diameter already installed, not just the model name. Since the R1S and R1T share the same size families, the correct tire choice usually comes down to whether your truck or SUV is on 20s, 21s, or 22s. A quick check of the sidewall on the tire already fitted is often the fastest way to confirm it.

On a 2023 Rivian Trucks tire, 275/50R22 means the tire is 275 millimeters wide, the sidewall height is 50 percent of that width, the R indicates radial construction, and the tire fits a 22-inch wheel. This is a modern metric radial format, so each part of the code has a direct dimensional meaning rather than the older naming conventions seen on vintage collector tires.

For a 2023 Rivian Trucks vehicle, that code matters because the 22-inch rim diameter is not interchangeable with the 20-inch or 21-inch sizes used elsewhere in the lineup. Even though the R1S and R1T can both use 275/50R22, the tire still must match the wheel on your specific vehicle. If you are replacing only one or two tires, confirm the exact size already mounted before mixing anything.

Yes and no: both 2023 Rivian Trucks models, the R1S and R1T, use the same three size families, but they do not use one single universal size. Each model can be found with 275/50R22, 275/55R21, or 275/65R20 depending on wheel package. All three are radial sizes, but each one fits a different rim diameter.

That shared sizing strategy simplifies research because you do not need separate size families for the pickup and SUV. The practical takeaway is that identifying the installed wheel diameter is more important than choosing between R1S and R1T at the year-make level. Once you know whether your 2023 Rivian Trucks vehicle is on 20-, 21-, or 22-inch wheels, the correct size path becomes much clearer.

BFGoodrich makes a tire for 2023 Rivian Trucks in 275/65R20, specifically the All-Terrain T/A KO2. That tire is a radial with an RBL sidewall and carries a 126S service description, which corresponds to an S speed rating. Brand coverage shown here is tied to that 20-inch size rather than the full Rivian wheel-diameter range.

For a 2023 Rivian Trucks owner, the brand question should come after the size question. Start by confirming whether your R1S or R1T is on 20-, 21-, or 22-inch wheels, then compare the products that match that exact fitment. If you are specifically interested in a more rugged all-terrain character, the BFGoodrich 275/65R20 is the clearest match among the options shown here.

2023 Rivian Trucks tires shown here include an RBL sidewall in 275/65R20. RBL stands for raised black letters, a style often chosen when owners want a more purposeful truck or SUV look rather than a plain blackwall appearance. Sidewall style details for the 21-inch and 22-inch Rivian sizes are not expanded here.

On a modern electric truck or SUV like a 2023 Rivian Trucks R1T or R1S, sidewall style is mostly an appearance decision unless you are trying to match an existing set. If your vehicle already has a certain visual theme, especially with off-road-oriented wheels or accessories, sidewall treatment can make a noticeable difference. It is worth checking how the spare or the remaining tires are finished before replacing only part of a set.

For 2023 Rivian Trucks, the BFGoodrich All-Terrain T/A KO2 appears in 275/65R20 as a radial tire with an RBL sidewall, a 126S service description, a maximum load of 3,750 pounds at 80 psi, and a recommended rim-width range of 7.5 to 9.5 inches. That gives it a clearly truck-focused specification within the 20-inch Rivian fitment family.

The main difference for a 2023 Rivian Trucks owner is that this product is tied to the 20-inch wheel package and carries an all-terrain identity, which will appeal to drivers using their R1T or R1S beyond pavement. It should not be treated as a substitute for the 21-inch or 22-inch tire sizes, even though the models share the same broader fitment family. Wheel diameter still has to match exactly.

Rim-width guidance shown here is available for the 275/65R20 used on 2023 Rivian Trucks. In that size, the BFGoodrich All-Terrain T/A KO2 fits rims from 7.5 to 9.5 inches wide. That specification applies to the tire product itself and works alongside the 20-inch rim diameter requirement for that size.

For a 2023 Rivian Trucks owner, rim width matters because the tire can physically mount only within the manufacturer’s approved wheel-width range. If your R1S or R1T has aftermarket wheels, confirm both the 20-inch diameter and the actual measured width before selecting the 275/65R20. The 21-inch and 22-inch sizes should be checked against the specifications of the exact tire chosen in those fitments.

The 275/65R20 product shown for 2023 Rivian Trucks does not carry a tube-type marking, and modern metric radial truck tires of this kind are typically used in tubeless service on the correct wheel. No inner-tube requirement is indicated for that BFGoodrich fitment. Tube information for the 21-inch and 22-inch sizes is not expanded here.

Most 2023 Rivian Trucks owners will be dealing with tubeless radial fitments, but it is still smart to confirm the exact sidewall markings of the tire you choose and the condition of the wheel itself. If a wheel has damage, corrosion, or an unusual aftermarket profile, sealing performance can be affected even when the tire is intended for tubeless use. Matching the tire to a sound, correct wheel is part of the setup.

Original 2023 Rivian Trucks wheels can be used only with the tire size that matches their diameter. A 20-inch Rivian wheel takes 275/65R20, a 21-inch wheel takes 275/55R21, and a 22-inch wheel takes 275/50R22. The R1S and R1T share those same size families, but the diameters are not interchangeable.

That means a 2023 Rivian Trucks owner cannot move between all three sizes without changing wheels as well. If you are considering a different look or a more off-road-oriented setup, verify both wheel diameter and wheel width before making the switch. Treat the existing tire sidewall and the wheel stampings as the first checkpoints, especially if the truck or SUV has been modified since new.

A 2023 Rivian Trucks vehicle should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Radial tires generally tolerate storage better than older bias-ply designs, but long periods of standing can still encourage flat spotting and cosmetic aging if the vehicle never moves.

For an R1S or R1T that sits through part of the year, roll the vehicle periodically or use stands if it will remain parked for an extended period. Keeping the tires clean and the storage area stable does more for longevity than dressing the sidewalls. It is also wise to check pressure before and after storage, since a heavy EV places meaningful static load on the tires.

Tires on a 2023 Rivian Trucks vehicle should be evaluated by age as well as tread wear. A sound rule for collector, specialty, or low-use vehicles is to begin paying close attention around five to seven years and to consider replacement around ten years regardless of remaining tread, using the DOT date code and the tire’s overall condition as the guide.

That age-based approach matters on a 2023 Rivian Trucks because many owners drive fewer miles than a typical daily-use truck or SUV would accumulate. A tire can look acceptable at a glance but still age out from heat cycles, time, and environmental exposure. Regular inspection and honest date-code review are more useful than relying only on tread depth when deciding whether to keep using an older set.

Tires on a 2023 Rivian Trucks should be inspected before every drive and again before any longer trip. Look for cuts, punctures, sidewall cracking, bulges, uneven wear, and any loss of pressure. Because these trucks and SUVs are substantial vehicles, even a small issue can become more serious quickly once speed and load are added.

A short walk-around is usually enough to catch the most common problems before they become roadside problems. For a 2023 Rivian Trucks owner, that should include checking tread depth across the tire face and making sure valve stems appear sound and seated correctly. If the vehicle has spent time parked, inspect more carefully, since age-related issues often show up after long static periods rather than during frequent use.

2023 Rivian Trucks tires can be suitable for highway driving when the correct size is matched to the correct wheel and the tire is in proper condition. The 275/65R20 BFGoodrich All-Terrain T/A KO2 carries an S speed rating, which corresponds to a 112 mph ceiling. In normal real-world use, the condition of the tire, inflation pressure, alignment, and the vehicle’s overall mechanical state matter more than chasing the upper edge of the speed symbol.

For a Rivian R1S or R1T, highway safety starts with confirming that all four tires match in size and type and that no tire is aged, damaged, or underinflated. Owners should also remember that a tire’s speed rating is not a target speed. Long trips, heavy loads, rough surfaces, and ambient heat all affect how comfortably and safely a tire operates on the road.

Inflation pressure for 2023 Rivian Trucks should follow the vehicle placard or owner’s manual for day-to-day service, while the tire manufacturer’s maximum-pressure figure helps describe the tire’s rated load capacity rather than serving as a universal operating recommendation. For the 275/65R20 BFGoodrich All-Terrain T/A KO2, maximum load is 3,750 pounds at 80 psi. That figure belongs to that exact size and tire.

A 2023 Rivian Trucks owner should not transfer that 80 psi figure to the 21-inch or 22-inch sizes, or even to every other 20-inch tire, because operating pressure depends on the exact tire and the vehicle’s intended use. Start with the factory vehicle recommendation, then fine-tune only within the tire maker’s guidance. Pressure should always be checked cold, especially before a trip or after seasonal temperature changes.

Before a longer drive in a 2023 Rivian Trucks vehicle, inspect each tire for cracking, cuts, bulges, embedded objects, uneven wear, and proper cold inflation pressure. Confirm that the spare, if equipped, is usable and correctly inflated, and make sure valve stems are intact and not leaking. Tire inspection should be one part of a broader pre-trip check on any modern truck or SUV.

For an R1S or R1T, it is smart to combine that tire inspection with a general look at brakes, suspension condition, wheel fastener security, and the condition of any recovery or roadside equipment you carry. Even when tread looks strong, a mismatched size or neglected pressure can compromise the trip. A few careful minutes in the driveway are far easier than sorting out a problem on the shoulder.
