A wheel washing assembly contains a machine frame, a pendulum assembly pivotably supported on the machine frame, and two washing manifolds, including a first washing manifold and a second washing manifold, attached to the pendulum assembly. Each of the washing manifolds has a nozzle assembly for ejecting water at a wheel to be washed. The washing manifolds are pivotable between a start washing position and an end washing position by an automatic motion of the pendulum assembly. The washing manifolds further automatically track the wheels to be washes by a motion of one of the wheels.
