Rivian built the R1T and R1S for adventure. The RT305 gives them wheels that look the part.
The RT305 is a natural evolution of our RT105, redesigned from the ground up as a fully forged wheel for the Rivian. The look will feel familiar to anyone who knows the RT105, but a lot of work went on behind the scenes to make it lighter and sleeker, while keeping the rugged character that made the original a favorite.
Forging is what makes the difference. A forged wheel is lighter and stronger than a cast one, and on an EV, every pound counts. Less unsprung weight means a more responsive ride and sharper handling, whether you're heading to the trailhead, the campsite, or just the office.
Fitment is straightforward. The RT305 uses the Rivian's factory 5x139.7 bolt pattern and 64.1mm center bore for a true hub-centric fit, with no hubrings or spacers needed. A +35 offset sets the wheel about 13mm further out than the factory wheels, giving your Rivian a wider, more planted stance. Refer to the Fitment Guide section below for year/model information.
Compatible with factory Rivian R1T/R1S TPMS sensors. A new valve stem service kit (stem, grommet, nut) for your sensor is recommended when transferring sensors.
