The 2024 Rivian Trucks R1T sits at the intersection of electric truck engineering and modern adventure use, blending quick road manners with genuine utility and off-pavement capability. Tire choice matters more than it does on many collector-era vehicles because the R1T appears here with three distinct radial fitments: 275/50R22, 275/55R21, and 275/65R20. That makes wheel diameter and sub-model identification the first step before comparing tires. The all-terrain package brings its own 20-inch fitment, while the other setups stay in lower-profile 21- and 22-inch formats. For an R1T owner, the real decision is matching the exact wheel and intended use before evaluating tread character and overall presentation.
Which Tire Size Is Right for The 2024 Rivian Trucks R1T
Three tire sizes apply to the 2024 Rivian Trucks R1T, and they are tied to specific sub-model configurations and wheel diameters. The first thing to confirm is whether the truck is running 20-, 21-, or 22-inch wheels, because each size is a radial fitment with a different overall profile. Once the wheel and sub-model are verified, the decision shifts to choosing the tire that matches how the truck is equipped and used.
275/50R22 is a metric radial size in which 275 identifies nominal section width in millimeters, 50 is the aspect ratio, R marks radial construction, and 22 is the rim diameter in inches. On the 2024 Rivian Trucks R1T, this size belongs to a 22-inch wheel setup and represents one of the lower-profile factory-style fitment paths for the model range covered here. Its practical role is tied to the exact wheel package rather than broad interchangeability. Before choosing this size, confirm that the truck is actually equipped with 22-inch wheels and that clearance remains appropriate if anything has been changed from stock.
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 2024 Rivian Trucks R1T, this size is associated with a 21-inch wheel configuration and sits between the 22-inch and 20-inch options in profile and wheel diameter. That makes it important to treat as its own fitment rather than as a simple variation of the others. Use this size only after confirming the truck's actual wheel setup, especially if wheels or suspension components have been changed.
275/65R20 is a metric radial size with a 275-millimeter nominal section width, a 65-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2024 Rivian Trucks R1T, this size is tied to the Adventure w/All-Terrain Pkg. configuration and carries the most purpose-built product choice shown here, a BFGoodrich All-Terrain T/A KO2 with an RBL sidewall. That gives this fitment a more specialized buying path than the other sizes. Confirm the 20-inch wheel package first, then compare rim-width compatibility and intended on-road versus all-terrain use before selecting a tire.
Sub-model fitment matters on the 2024 Rivian Trucks R1T because tire size changes with the wheel and package configuration. Identifying whether the truck is an Adventure or an Adventure w/All-Terrain Pkg. is the clearest way to narrow the correct radial size before comparing tire options.

2024 Rivian Trucks R1T Adventure
The 2024 Rivian Trucks R1T Adventure uses two radial fitment paths, depending on whether the truck carries the 21-inch or 22-inch wheel setup. That means tire selection starts with confirming actual wheel diameter, then choosing the size that matches the truck's present configuration rather than assuming every Adventure uses the same tire.
The 2024 Rivian Trucks R1T Adventure w/All-Terrain Pkg. uses the 275/65R20 radial fitment on a 20-inch wheel. That makes this sub-model the most straightforward path for buyers comparing all-terrain-oriented products, but wheel width and any suspension or wheel changes should still be checked before final selection.
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.
Best 2024 Rivian Trucks R1T Tires for Sale
Current product coverage centers on the 275/65R20 fitment, with a BFGoodrich All-Terrain T/A KO2 radial option. For R1T owners using the all-terrain package, the main comparison points are tire series character, RBL sidewall styling, and the stated 7.5- to 9.5-inch rim-width range.
R1T fitment questions usually come down to wheel diameter, sub-model package, and how each radial size relates to the truck's intended use. The FAQs below focus on exact tire size, rim fitment, product selection, and the checks worth making before road or trail use.
Tire Size & Fitment
What tire size fits a 2024 Rivian Trucks R1T?
The 2024 Rivian Trucks R1T uses three radial tire sizes: 275/50R22, 275/55R21, and 275/65R20. The correct size depends on the truck's exact sub-model configuration and wheel package, with the Adventure using either 21-inch or 22-inch fitments and the Adventure w/All-Terrain Pkg. using the 20-inch fitment.
The most important step is confirming the actual wheel diameter on the truck before choosing a tire. These sizes are not just alternate profiles on the same wheel, so a 20-inch all-terrain setup, a 21-inch setup, and a 22-inch setup need to be treated as separate fitments.
What size rim does a 2024 Rivian Trucks R1T use?
A 2024 Rivian Trucks R1T can use 20-inch, 21-inch, or 22-inch rims, depending on configuration. The matching tire sizes are 275/65R20 for the 20-inch setup, 275/55R21 for the 21-inch setup, and 275/50R22 for the 22-inch setup.
Rim diameter should be verified before anything else because each tire size is built around a different wheel. If the truck has aftermarket wheels or a wheel-and-tire package change from its original setup, check the actual wheel markings and overall clearance instead of relying only on the sub-model name.
Why does the 2024 Rivian Trucks R1T have more than one tire size?
The 2024 Rivian Trucks R1T has more than one tire size because different wheel and package configurations use different radial fitments. The Adventure can be equipped with 275/55R21 or 275/50R22, while the Adventure w/All-Terrain Pkg. uses 275/65R20.
That means the right tire is determined by how the truck is equipped, not simply by year, make, and model alone. Wheel diameter is the key checkpoint, and package differences matter because they affect which tire profile and construction format belong on the truck.
Choosing the Right Tire
What should I consider when choosing a 275/65R20 tire for a 2024 Rivian Trucks R1T?
Start with exact size, construction, and wheel compatibility. For a 2024 Rivian Trucks R1T using 275/65R20, the available product shown here is a radial BFGoodrich All-Terrain T/A KO2 with a 7.5- to 9.5-inch rim-width range and a maximum load capacity of 3,750 lbs @ 80 psi.
That makes this fitment especially dependent on confirming the truck's actual 20-inch wheel setup and intended use. Buyers should compare rim width, tread character, load needs, and whether the truck spends more time on pavement or in mixed-surface driving before settling on a 275/65R20 tire.
What brands offer tires for the 2024 Rivian Trucks R1T?
The available product coverage shown here includes BFGoodrich for the 275/65R20 fitment on the 2024 Rivian Trucks R1T. That option appears in the All-Terrain T/A KO2 series and is tied to the 20-inch all-terrain-oriented setup rather than the full spread of R1T wheel configurations.
Brand comparison only matters after confirming the truck's exact tire size and wheel diameter. An R1T owner should first determine whether the truck is on 20-, 21-, or 22-inch wheels, then compare the products available in that exact size instead of treating all R1T tire options as interchangeable.
How do I choose between the available 2024 Rivian Trucks R1T tires?
The right starting point is the truck's exact size: 275/50R22, 275/55R21, or 275/65R20. After that, compare the tire's construction, wheel compatibility, load capacity where stated, tread character, and sidewall presentation, since those details shape how well a tire matches the R1T's current setup and intended use.
A truck on the all-terrain package should be evaluated differently from one on a 21-inch or 22-inch wheel package. It also helps to confirm whether the R1T remains stock, because aftermarket wheels, suspension changes, or a change in driving conditions can alter what makes the most sensible tire choice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Rivian Trucks R1T?
Yes. Modifications such as aftermarket wheels, wheel offset changes, suspension adjustments, or body-height changes can affect tire fitment on a 2024 Rivian Trucks R1T even when the tire size looks close to stock. That matters especially here because the truck already uses three distinct wheel diameters across its covered configurations.
Any change in wheel width, offset, or suspension position can alter fender and steering clearance. A modified R1T should be checked for actual wheel diameter, rim width, and clearance at full steering lock and suspension movement before selecting replacement tires in 20-, 21-, or 22-inch sizes.
What should I inspect before driving a 2024 Rivian Trucks R1T on new tires?
Before road use, inspect air pressure, wheel hardware, valve stems, tread and sidewall condition, and confirm that all four tires are the correct size for the truck's wheel package. On a 2024 Rivian Trucks R1T, it is also important to verify that the installed tires match the actual 20-, 21-, or 22-inch wheels.
A close look at clearance is worthwhile after installation, especially if the truck has accessory wheels or suspension changes. It also helps to recheck pressure after the first drives and watch for any signs of rubbing, vibration, uneven wear, or slow air loss before putting the R1T into regular use.
What should I check before a longer drive in a 2024 Rivian Trucks R1T?
Before a longer drive, check tire pressure, tread condition, sidewalls, and any signs of puncture damage or irregular wear. A 2024 Rivian Trucks R1T should also be checked to make sure the tire size matches the truck's exact wheel setup, since 20-, 21-, and 22-inch configurations are all used.
Longer trips are a good time to catch issues such as rubbing, vibration, or slow air loss that may not show up around town. It is also smart to confirm wheel fastener security and review the condition of tires that have seen off-pavement use, curb contact, or long periods of inactivity.
