The apparatus for washing the wheels (2) of vehicles in a washing plant has two oppositely arranged rotating wash brushes (4) each of which is associated with the wheels of one side of the vehicle and adjustable in the vehicle's direction of movement (B) on a carriage movable together with the vehicle in the vehicle's direction of movement (B) by means of a drive motor, and which during the washing phase can be pressed against one wheel (2) at a time. A light barrier (12, 13) is provided between the oppositely arranged carriages (6) and connected thereto and its light beam (15) is spaced from the axes of rotation (A) of the wash brushes (4) at a radial distance (R1) which corresponds approximately to the radius (R) of an average wheel size. A follower control device acting upon the drive motors (9) is designed in such a way that during the washing phase the carriages (6) can be advanced further in the vehicle's direction of movement (B) by the drive motors (9) according to the respective position of the wheel (2) about to be washed, which is scanned by the light barrier (12, 13).
