As the vehicle moves, the wheel rotates with the axle, transferring motion to the tire for forward travel. Its role centers on supporting load while allowing consistent rotation through the hub pilot interface. The wheel functions as a structural component rather than a control device, remaining fixed to the hub while turning as a unit. This interaction repeats continuously under driving conditions. The Alcoa ULA187 supports wheel rotation and tire mounting across road use.
