The Black Rhino Rockledge BR406 is a forged wheel engineered specifically for the Rivian R1T and R1S — built to extend what these electric trucks can do when the pavement runs out. The Rockledge features a techform five-spoke design that blends soft curves with sharp bevels for a high-tech aesthetic that looks as purposeful as it is strong. Constructed from 6061-T6 forged aluminium, it's sized at 20x8.5" with a +35mm offset and 5x139.7 bolt pattern, dialled precisely for Rivian fitment.
The Rockledge also comes with Black Rhino's AeroDisc system — a removable disc designed to reduce open-spoke exposure and manage airflow without compromising brake cooling. It's a practical feature that lets Rivian owners switch the look and function of the wheel between trail use and street driving with ease. The Matte Gunmetal finish gives the Rockledge a cool, understated presence — a flat, dark grey tone that complements the R1T and R1S's modern lines and suits a wide range of build colours from silver and charcoal through to white and earth tones.

Wheel Offset is the clearance between the inside of the wheel and the strut housing. It will also show how far the outside of the wheel edge will extend or retract. If you reduce the inner clearance too much or push the wheel out too far, the tire might rub or not fit at all. This calculator is for information purposes only and we do not guarantee fitment based on this calculator alone.
