The Rivian R1S is a full-size electric SUV with three-row seating, quad-motor AWD, and standard all-terrain capability. It weighs approximately 7,100 lbs — in the weight class of a heavy-duty truck. This creates unique tire requirements: the load rating must handle extreme weight, while the design must balance off-road capability with EV range. The factory-equipped Pirelli Scorpion all-terrain tires are a thoughtful OEM choice that most owners should understand before replacing.
Rivian R1S tire size
The Rivian R1S uses 275/65R20 as the standard tire size on 20-inch all-terrain wheels. The optional 22-inch Sport Road wheels use 275/50R22. The standard 20-inch size is the most common for R1S owners since it is included on most configurations.
Load rating is critical on the R1S — the vehicle weighs over 7,000 lbs. Never install a tire with a lower load index than specified. The door sticker load index should be treated as an absolute minimum, not a starting point.
Rivian OEM tires — Pirelli Scorpion All Terrain Plus
Rivian ships the R1S with Pirelli Scorpion All Terrain Plus tires in 275/65R20 at the correct load rating for the vehicle. This is a thoughtful OEM choice — the Scorpion ATR handles both on-road and moderate off-road use, is quieter than most dedicated all-terrain tires, and Pirelli calibrated it specifically for the R1S application.
Before replacing the OEM tires, evaluate whether the factory choice was actually wrong for your use case. Many R1S owners replace the Pirelli Scorpion thinking they can do better, only to find the replacements are louder, have higher rolling resistance, or do not handle the vehicle weight as well.

Best replacement tires for the Rivian R1S
Michelin LTX A/T2 (275/65R20): for R1S owners who want a quieter, more comfortable highway character while retaining moderate off-road capability. It handles the R1S weight well and is measurably quieter on pavement than the OEM Pirelli.
BFGoodrich All-Terrain T/A KO2 (275/65R20): for R1S owners who want more off-road capability than the OEM tire delivers. It's more aggressive and handles rocks and mud better, at the cost of some on-road noise and rolling resistance. Verify load rating before purchasing.
Continental CrossContact ATR (275/65R20): an all-terrain option with better road manners than the KO2. It's quiet for an all-terrain tire, with good wet performance, and comes in the R1S size with adequate load rating. A good compromise between highway refinement and off-road competence.

Frequently asked
What tire size does the Rivian R1S use?
Standard 20-inch all-terrain wheels: 275/65R20. Optional Sport Road 22-inch wheels: 275/50R22. Verify on the driver door sticker.
Can I put regular tires on a Rivian R1S?
You can use any tire in the correct size with adequate load rating. The key constraints are size (275/65R20) and load index — the R1S at 7,100+ lbs demands high load ratings. Standard passenger car (P-metric) tires typically do not have adequate load ratings for the R1S. Stick to LT-rated or SUV tires with the correct load index.
Why do the tires on my R1S wear out so fast?
Weight and torque. The R1S is as heavy as a full-size truck and delivers instant power to all four wheels, both of which grind tread faster than a gas SUV would. Rotating on the frequent side and going easy on the throttle both stretch the life meaningfully. Aggressive all-terrain tires wear faster still, so match the tread to how much you actually go off-road.
Should I replace all four tires at once on an R1S?
Yes. It is a quad-motor all-wheel-drive vehicle, so mismatched tread across the axles can confuse the system and add wear on the drivetrain. The R1S also tends to wear its tires fairly evenly, so all four usually reach the end around the same time. If one is damaged early, match it closely or replace the set.
