A dynamic vehicle wheel balance apparatus, a vehicle wheel, a powered vehicle, and a related method for manufacture are provided. The dynamic vehicle wheel balance apparatus comprises a vehicle wheel cover and a dynamic vehicle wheel balance ring. The vehicle wheel cover comprises a first surface, a second surface, and a perimeter surface connecting the first surface to the second surface. The vehicle wheel cover is configured to removably attach to a flange of a vehicle wheel with the second surface opposing the vehicle wheel. The dynamic vehicle wheel balance ring is attached to the second surface of the vehicle wheel cover. The dynamic vehicle wheel balance apparatus dynamically balances the vehicle wheel during rotation of the vehicle wheel and reduces aerodynamic drag.
