2025 Rivian Trucks Tire Fitment Guide

2025 Rivian Trucks vehicles use three tire sizes across the full R1S and R1T range: 275/50R22, 275/60R20, and 275/65R20. Both models share all three sizes, so there is no model-exclusive fitment split between the R1S and R1T. The 275/50R22 mounts on a 22-inch wheel, while the 275/60R20 and 275/65R20 mount on 20-inch wheels. For 275/65R20, the supported rim width runs from 7.5 to 9.5 inches.

That means the first fitment check on a 2025 Rivian Trucks vehicle is wheel diameter, not whether you own the pickup or the SUV. Once you confirm 20-inch versus 22-inch wheels, you can narrow the choice to the exact size already on the vehicle or the size approved for your wheel setup. If you are considering a move between the two 20-inch sizes, verify wheel width and clearance before making the change.

On a 2025 Rivian Trucks tire, 275/50R22 is a metric radial size. The 275 is the tire's nominal section width in millimeters, 50 is the aspect ratio, meaning the sidewall height is 50 percent of the section width, R identifies radial construction, and 22 is the wheel diameter in inches. On 2025 Rivian Trucks, this size is used on both the R1S and R1T.

The practical takeaway is that 275/50R22 is tied to a 22-inch wheel package, so it cannot be interchanged with 20-inch sizes unless the wheels themselves change. When comparing products, keep the code intact and then look at sidewall style, load rating, and speed rating on the exact tire. That approach prevents mixing up a similar-width tire that fits an entirely different wheel diameter.

Yes, 2025 Rivian Trucks models share the same three tire sizes. Both the R1S and the R1T use 275/50R22, 275/60R20, and 275/65R20, and all are radial sizes. The difference is not a separate R1S-only or R1T-only tire size, but which wheel and tire package a particular vehicle was equipped with.

That shared fitment simplifies research because you do not need to start by separating the SUV from the pickup. Instead, inspect the tire sidewall already on the vehicle or confirm the wheel diameter first. After that, compare the exact size and tire type you want, especially if your Rivian is used for more trail-oriented driving or if you are trying to keep the same wheel appearance and stance.

For a 2025 Rivian Trucks vehicle, the 275/60R20 and 275/65R20 are both 20-inch radial sizes used on the R1S and R1T, but they are not the same dimensions. The 275/65R20 example available here is a BFGoodrich All-Terrain T/A KO2 with an RBL sidewall, an S speed rating, and a 3,750-pound maximum load at 80 psi. That makes it a clearly defined 20-inch option with an all-terrain character.

The right choice depends on matching the exact size approved for your wheel and vehicle setup, not simply choosing either 20-inch size interchangeably. If your Rivian already wears 275/60R20, stay with that size unless you have confirmed wheel width, clearance, and any calibration considerations. If it wears 275/65R20, compare products within that size and keep the tire's load and speed markings aligned with how the vehicle is used.

Sidewall style can vary by exact tire, and the 275/65R20 option currently covered for 2025 Rivian Trucks uses an RBL sidewall, meaning raised black letters. The 2025 Rivian Trucks range as a whole uses radial metric sizes, so sidewall appearance is more about the character of the specific tire than about vintage-era authenticity. On modern electric trucks and SUVs, blackwall and lettered off-road sidewall treatments are the most common visual directions.

For buyers, sidewall style matters both visually and functionally. A more aggressive all-terrain tire often carries styling cues that fit the adventure-oriented personality of the R1T and R1S, while a plainer sidewall may better suit a road-focused look. If appearance matters as much as fitment, check the exact sidewall marking on the tire you are considering rather than assuming every tire in the same size will look the same.

BFGoodrich is represented for 2025 Rivian Trucks in 275/65R20 with the All-Terrain T/A KO2. That tire is a radial all-terrain design with an RBL sidewall, an S speed rating, and a 20-inch rim diameter. Brand coverage can differ by exact size, so the 22-inch and alternate 20-inch fitments should be matched to the tire size on the vehicle before narrowing down brand preference.

Brand choice on a modern Rivian usually comes down to intended use, sidewall appearance, and the exact load and speed markings on the tire. If your vehicle is equipped with 275/65R20, BFGoodrich is a direct option in that size. If it uses 275/50R22 or 275/60R20, start with the size first and then compare the available product family that matches that wheel package.

Rim width guidance is available for 2025 Rivian Trucks in 275/65R20, where the supported wheel width range is 7.5 to 9.5 inches on a 20-inch rim. That figure applies to the tire product in that size, not automatically to every other 20-inch or 22-inch option across the Rivian range. The other two Rivian sizes still need to be matched to the actual wheel and tire specification being used.

Rim width matters because it affects sidewall shape, tread support, and overall fit on the wheel. Even when two tires share the same 20-inch diameter, the approved wheel-width range may differ from one size or product to another. Before changing from one 20-inch size to another on a 2025 Rivian Trucks vehicle, confirm that the exact wheel width falls within the tire maker's approved range.

The 2025 Rivian Trucks sizes are modern radial metric fitments, and the 275/65R20 example covered here appears as a tubeless-style radial with no tube-type marking. That points buyers toward modern tubeless fitment rather than vintage tube-type construction. Tube requirements can still depend on the exact wheel and tire combination, so the sidewall marking on the specific tire should be checked before installation.

For most buyers, the practical concern is not adding a tube by default, but making sure the wheel condition, valve hardware, and tire marking all align. If your Rivian uses factory-style modern wheels, the setup will typically center on tubeless operation. When replacing tires, confirm the exact product marking and inspect the wheel bead area so the installation matches the tire's intended design.

Original 2025 Rivian Trucks wheels can only be shared among tire sizes that use the same rim diameter. The 275/50R22 requires a 22-inch wheel, while the 275/60R20 and 275/65R20 both require 20-inch wheels. That means a 22-inch Rivian wheel cannot take the 20-inch sizes, and a 20-inch Rivian wheel cannot take the 22-inch size.

Within the 20-inch group, a change between 275/60R20 and 275/65R20 still needs a careful check of wheel width and vehicle clearance before assuming interchangeability. Diameter matching is only the first step. If you are staying with the wheel that is already on the vehicle, verify the exact tire code on the sidewall and keep the replacement within the approved range for that wheel.

A 2025 Rivian Trucks vehicle should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Modern radial tires tolerate storage better than older bias-ply designs, but they still age from heat, UV exposure, and long periods of static load. Moving the vehicle occasionally or using stands for very long storage can help reduce flat spotting and stress at one contact patch.

That matters on an R1S or R1T because many owners rotate between daily use, seasonal travel, and long parked periods. Keep the tires off wet ground, maintain recommended pressure, and inspect sidewalls before the vehicle returns to regular service. If the vehicle sits for extended stretches, check the spare as well, since an emergency tire that has aged in silence is easy to overlook.

Tires on a 2025 Rivian Trucks vehicle should be judged as much by age as by tread depth. A good collector and specialty-vehicle rule is to begin evaluating tires closely at around five to seven years of service and to treat ten years as a serious replacement threshold, even if the tread still looks usable. The DOT date code on the sidewall gives the tire's week and year of manufacture.

Electric trucks and SUVs can place substantial weight and torque through the tires, so age-related hardening or cracking deserves attention even when mileage seems low. Regular use, climate, storage conditions, and inflation history all influence longevity. If a Rivian tire shows sidewall cracking, impact damage, or abnormal wear before it reaches those age markers, condition matters more than the calendar target.

Tires on a 2025 Rivian Trucks vehicle should be inspected before every drive and again before any extended highway or off-pavement trip. Check for cuts, bulges, embedded objects, uneven wear, and pressure loss, and make sure the tread and sidewall remain free from cracking or impact damage. Because these are modern radial sizes, steady pressure retention and clean bead sealing are especially important signs of a healthy setup.

Frequent inspection helps catch problems early on vehicles that may alternate between heavy use and parked intervals. Pay special attention after trail use, pothole strikes, or curb contact, since those conditions can damage a tire without immediately causing a flat. A quick walkaround and pressure check takes only a few minutes and is one of the best habits for keeping a 2025 Rivian Trucks vehicle ready for dependable use.

2025 Rivian Trucks tires can be entirely appropriate for highway driving when the exact tire size, load rating, inflation pressure, and speed rating match the vehicle's needs. The 275/65R20 BFGoodrich option carries an S speed rating, which corresponds to a 112 mph ceiling. That is comfortably above normal U.S. highway speeds, provided the tire is in good condition and used within its rated load and pressure limits.

The larger safety picture on a modern electric truck or SUV also includes weight, braking condition, alignment, and the kind of driving the vehicle sees. A tire with a suitable speed symbol is only one part of the equation. Before long highway use, confirm that all four tires match in size and service character, and avoid treating a maximum speed symbol as a target rather than a tested upper limit.

Inflation pressure for a 2025 Rivian Trucks tire should follow the vehicle placard or owner's literature for normal service, then be checked against the exact tire's own maximum rating. For the 275/65R20 BFGoodrich All-Terrain T/A KO2, the tire's maximum load is 3,750 pounds at 80 psi. That figure is the tire's rated upper condition, not a universal operating pressure for every 2025 Rivian Trucks tire size.

Use the factory vehicle recommendation as your baseline for everyday driving, because it accounts for the Rivian's weight distribution, suspension tuning, and intended load use. If you change to a different size or tire type, read the sidewall and manufacturer guidance for that exact product rather than carrying over a pressure figure from another size. Pressure should always be checked cold for an accurate reading.

Before a longer drive in a 2025 Rivian Trucks vehicle, inspect all tires for cracking, punctures, bulges, tread damage, and uneven wear, then verify cold inflation pressure. Make sure the tire size matches at all four corners where required, and inspect the spare if the vehicle carries one. On a 20-inch all-terrain setup, also look closely for cuts or bruising from previous off-road use that may not be obvious at a glance.

Tire condition is only one part of a sound pre-trip routine, but it is one of the easiest checks to perform and one of the most important for safety. A careful inspection should be paired with a broader review of brakes, alignment feel, and any suspension issues that could accelerate wear. Catching a damaged sidewall or a slow leak before departure is far better than discovering it miles into the trip.
