The two things that affect tires are time and mileage. Naturally, the compounds on tires have a limited lifespan as they begin to breakdown over time. The mileage on a tire is only a general indication of it’s wear and usage. Neither time nor mileage are accurate indicators of a tire’s usability. The reason for that is because factors such as tire storage and care can improve or diminish lifespan. Typically most tires are manufactured to last at least five years under normal circumstances. If your tires are older than 5 years, it may be a good idea to consider replacements.
Reading the sidewall and understand tire sizing options can seem difficult at first. Once you learn the basics of what these numbers and markings mean, it becomes much simpler. Oftentimes original equipment tires use standard sizing designations, such as 255/70R17. However, when upgrading tires, especially for the Rivian R1T, you may come across flotation sizing designations. These will typically read as 35×12.50×17.
The Rivian R1S offers four factory tire size options across different trim packages: 275/60R20 (32.99" diameter) on 20" Road wheels, 275/65R20 (34.07" diameter) on 20" All-Terrain wheels, 275/55R21 (32.91" diameter) on 21" Road wheels, and 275/50R22 (32.83" diameter) on 22" Sport wheels. All sizes maintain a consistent 10.83" width regardless of wheel diameter.
The 20" All-Terrain tire package with 275/65R20 sizing is primarily available on the Adventure and Launch Edition trims. These wheels come in three finishes: standard All-Terrain, All-Terrain Bright, and All-Terrain Dark, allowing you to match your vehicle's aesthetic preferences while maintaining off-road capability.
Despite ranging from 20" to 22" wheel diameters, the overall tire diameters remain relatively similar due to sidewall adjustments. The 20" All-Terrain setup (275/65R20) has the largest overall diameter at 34.07", while the 20" Road (275/60R20), 21" Road (275/55R21), and 22" Sport (275/50R22) options range between 32.83" and 32.99". This design maintains consistent ground clearance and speedometer accuracy across configurations.
Yes, Rivian offers wheel and tire sets through their official Gear Shop, including 20" All-Terrain and 22" Sport configurations. These factory-compatible options ensure proper fitment and maintain your vehicle's warranty coverage, making it easy to switch between wheel styles for different driving conditions or aesthetic preferences.
The Explore Package typically comes standard with 21" Road wheels (275/55R21) focused on range efficiency, while the Adventure Package offers more rugged options including 20" All-Terrain wheels (275/65R20) for off-road capability and 22" Sport wheels (275/50R22) for a more aggressive look. The motor configuration (Dual Standard, Dual Performance, Tri, or Quad) doesn't determine wheel availability—trim level does.
