SoonishEV 18" Off-Road Wheels (set of four) for the Rivian R2

The Rivian R2 is an incredibly capable machine right off the assembly line, but true off-road performance demands one thing the factory didn't provide: sidewall. We designed the SoonishEV 18" Off-Road Wheel to unlock the full trail potential of your R2, giving you the clearance, grip, and durability required to push further off the grid.

By dropping the wheel diameter down to 18 inches, you instantly gain the ability to mount dedicated, heavy-duty all-terrain and mud-terrain tires. More rubber means vastly improved shock absorption on washboard roads, a dramatically larger contact patch when aired down for sand or crawling, and unparalleled protection against pinch flats on jagged rocks.

Engineered specifically for the unique load demands and immediate torque of an EV, this wheel isn't just a resized generic truck rim. It is purpose-built to clear the R2's brake calipers while maintaining a flush, aggressive stance that looks right at home deep in the woods or navigating the city.

The Sidewall Advantage

Factory 19-inch and 20-inch wheels force you into low-profile all-terrains that compromise trail comfort and grip. Stepping down to an 18-inch wheel allows you to wrap your wheels in thick, aggressive rubber. When you drop your tire pressure at the trailhead, that extra sidewall flexes to wrap around obstacles, providing the mechanical grip you need to conquer steep inclines and deep ruts.

Key Features

• EV-Specific Load Rating: Reinforced barrel and spoke design to effortlessly handle the heavy curb weight and instant torque of the R2 platform.

• Hub-Centric Precision: Machined exactly for the R2 hub to ensure a vibration-free ride at highway speeds, with zero need for aftermarket hub rings.

• Optimized Offset: Pushes the tire out just enough to provide an aggressive, wide track for stability while keeping the tread under the fenders to minimize mud sling.
