1221 Wheels worked tirelessly on our truck wheels to be aggressive, yet timeless and compliment the functional development ethos in the performance off-road space. 1221 Wheels developed a brand-new profile for this project to achieve the most concave look possible for truck wheels. By utilizing the latest design, engineering, and FEA technology, 1221 Wheels was able to create the most extreme off-road truck wheels on the market. The wheels are lighter, stronger, and feature the most extreme concave profiles available today.
