2024 Rivian Trucks Tire Fitment Guide

2024 Rivian Trucks use three radial sizes: 275/65R20, 275/55R21, and 275/50R22. Both the 2024 Rivian Trucks R1S and 2024 Rivian Trucks R1T use all three sizes, so the fitment difference is not between models but between wheel packages. The available rim diameter for each size is built into the code itself: 20 inches, 21 inches, or 22 inches.

That means the first thing to confirm on a 2024 Rivian Trucks vehicle is the wheel diameter already on the truck. A 20-inch tire does not substitute directly for a 21-inch or 22-inch wheel, even though the section width stays at 275 millimeters across all three sizes. Once the wheel package is confirmed, you can narrow the choice by tread style, intended road use, and sidewall appearance.

On a 2024 Rivian Trucks tire, 275/65R20 is a metric radial size. The 275 is the nominal section width in millimeters, 65 is the aspect ratio, the R identifies radial construction, and 20 is the wheel diameter in inches. This size is used on both the 2024 Rivian Trucks R1S and the 2024 Rivian Trucks R1T.

For a Rivian owner, that code matters because it ties the tire to a specific 20-inch wheel package. It also signals the overall tire profile relative to the 21-inch and 22-inch options used elsewhere in the lineup. If your truck has 20-inch wheels and you want to stay within the correct size family, 275/65R20 is the place to start before comparing tread pattern, sidewall styling, or load and speed details.

Yes, the 2024 Rivian Trucks R1S and 2024 Rivian Trucks R1T share the same three tire sizes: 275/65R20, 275/55R21, and 275/50R22. Rivian uses the same basic sizing family across both models, so there is no separate R1S-only or R1T-only fitment among these three sizes. The difference comes from which wheel package is installed on a particular truck.

That shared sizing approach simplifies year-and-make research, but it does not eliminate the need to verify the actual wheel on your vehicle. A buyer who knows only that the truck is a 2024 Rivian still needs to check whether it rides on 20-inch, 21-inch, or 22-inch wheels. Matching the tire to the wheel package is more important here than choosing between the R1S and R1T nameplates.

Among the currently covered 2024 Rivian Trucks products, the 275/65R20 is available with an RBL sidewall from BFGoodrich. That means raised black lettering is part of the visible look for that specific 20-inch all-terrain option. Sidewall appearance can vary by size and product, so the sidewall style should be checked on the exact tire rather than assumed across the whole Rivian range.

Sidewall style matters most when you want the truck’s tire appearance to match its intended character. An RBL sidewall gives the 20-inch all-terrain setup a more purposeful, off-road-oriented visual tone than a plain blackwall would. If appearance is part of the decision, confirm the sidewall treatment alongside the size code so the tire fits both the wheel package and the look you want.

BFGoodrich currently covers the 275/65R20 size for 2024 Rivian Trucks with the All-Terrain T/A KO2. That tire fits both the 2024 Rivian Trucks R1S and the 2024 Rivian Trucks R1T when they are equipped with 20-inch wheels. Brand coverage can differ by size, so a truck on 21-inch or 22-inch wheels should be matched by size first and brand second.

For buyers, the practical takeaway is that brand choice begins with the wheel package already on the truck. If your 2024 Rivian Trucks vehicle uses 275/65R20, BFGoodrich is the confirmed option in that fitment family here. If your truck uses 275/55R21 or 275/50R22, start by confirming that exact size so you can compare products built for that specific wheel diameter.

For 2024 Rivian Trucks, the BFGoodrich All-Terrain T/A KO2 is the covered option in 275/65R20. It is a radial tire with an RBL sidewall, a 3,750-pound maximum load at 80 psi, an S speed rating, and a recommended rim-width range of 7.5 to 9.5 inches. The other Rivian sizes in this year-and-make family are 275/55R21 and 275/50R22, which belong to different wheel packages rather than being direct same-wheel substitutes.

That means the KO2 is not simply an alternate tread for every 2024 Rivian Trucks setup; it is a tire built around the 20-inch package. If your truck already wears 20-inch wheels and you want an all-terrain style radial, it is the relevant comparison point. If your truck has 21-inch or 22-inch wheels, the first decision is not between tire models but between staying with the correct wheel-specific size.

For the 2024 Rivian Trucks 275/65R20 size, the covered BFGoodrich tire fits a rim-width range of 7.5 to 9.5 inches on a 20-inch wheel. The 275/55R21 and 275/50R22 sizes belong to 21-inch and 22-inch wheel packages respectively, though a rim-width range is not included here for those two sizes. Rim diameter still remains fixed by the tire code itself.

Rim width matters because it affects how the tire sits on the wheel and how the tread presents on the road. Even when the diameter is correct, the wheel should still fall within the tire maker’s approved range for that specific product. On a 2024 Rivian Trucks vehicle, confirm both the wheel diameter and the actual wheel width before mounting a replacement tire.

The covered 275/65R20 tire for 2024 Rivian Trucks does not carry a tube-type marking, and it is presented as a modern radial product rather than a tube-type specialty fitment. Tube requirements can vary by product design and by wheel construction, so the exact sidewall marking and the wheel itself should be checked together. That is especially important when a buyer is replacing one tire rather than a full set.

Modern Rivian applications are generally approached as tubeless wheel-and-tire assemblies, but the safe habit is still to verify the product and the wheel before installation. A damaged bead seat, prior repair history, or an unusual wheel condition can change the setup conversation. If there is any doubt, use the tire’s sidewall marking and the wheel manufacturer’s guidance as the final reference.

A 2024 Rivian Trucks vehicle should be stored away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber more quickly. Keep the truck on a clean, dry surface and maintain proper inflation during storage. If it will sit for extended periods, moving it occasionally helps prevent prolonged loading in one contact patch.

That approach protects both appearance and long-term service life, especially on a heavier electric truck where static load can be substantial. Owners who store a 2024 Rivian Trucks vehicle seasonally often benefit from checking pressure monthly and rolling the truck slightly to vary the footprint. If storage will be very long, consult a trusted service source about support methods that avoid stressing the tires.

Tire age on a 2024 Rivian Trucks vehicle should be judged by time and condition, not just mileage. A good rule is to begin more careful age-based evaluation around five to seven years and to consider replacement as tires approach roughly ten years, even if tread remains. The DOT date code on the sidewall is the standard way to verify the tire’s build age.

That matters because many premium or specialty vehicles accumulate miles slowly while the rubber still hardens with time. A 2024 Rivian Trucks owner should treat visible cracking, repeated air loss, impact damage, or abnormal wear as reasons to inspect sooner rather than later. Tire longevity is always tied to storage conditions, inflation habits, driving style, and the weight the tire carries.

Tires on a 2024 Rivian Trucks vehicle should be inspected before every drive and again before any longer trip. Look for cuts, sidewall bulges, embedded objects, uneven wear, and pressure loss, and confirm that the tread is wearing evenly across the tire. A quick visual inspection catches many problems before they become vibration, handling, or durability issues.

A more thorough check every few weeks is wise if the truck sees regular road use, towing, or rough-surface driving. On a 2024 Rivian Trucks application, attention to pressure is especially important because load, range, and road feel are all affected by inflation. If one tire repeatedly loses air or shows unusual wear compared with the others, inspect the wheel and valve area as well as the tire itself.

2024 Rivian Trucks use modern radial tire sizes, and the covered 275/65R20 BFGoodrich tire carries an S speed rating, which corresponds to a 112 mph maximum rating under the tire maker’s test conditions. That is well above normal U.S. highway speeds. For everyday road use, the condition, inflation, and load carried by the tire matter as much as the speed symbol itself.

Real-world safety on a 2024 Rivian Trucks vehicle also depends on the truck’s weight, alignment, suspension condition, and how it is being used. An all-terrain tire may feel different from a road-focused tire even when both are highway-capable. Before longer high-speed travel, make sure the tires are correctly inflated, free of damage, and appropriate for the actual wheel package on the truck.

For the covered 275/65R20 tire on 2024 Rivian Trucks, the maximum load figure is 3,750 pounds at 80 psi. That number is the tire’s rated maximum for load and pressure, not automatically the day-to-day pressure every Rivian should run. The correct operating pressure for your truck should be confirmed against Rivian’s factory guidance and the specifications for the exact tire you are using.

Pressure should never be transferred from one size to another just because all three fit the same year and make. A 275/65R20, 275/55R21, and 275/50R22 are different fitment packages with different operating needs. Check pressures when the tires are cold, adjust for the wheel-and-tire package actually installed, and revisit them any time the truck’s load or use pattern changes significantly.

Before a longer drive in a 2024 Rivian Trucks vehicle, inspect all four tires for cracking, punctures, bulges, irregular wear, and correct cold inflation pressure. Confirm that the tire size on the truck matches the wheel package, and inspect the spare or emergency tire solution if the vehicle is equipped with one. A quick walkaround should also include valve stems and wheel condition.

Tires are only one part of trip preparation on a modern electric truck, but they are among the most important. A 2024 Rivian Trucks owner should also think about alignment symptoms, vibration, recent curb impacts, and whether the truck will carry passengers, cargo, or towing load on the trip. Catching a tire issue in the driveway is far easier than managing it after hours on the road.
