Abstract: A brush structure including a resilient member which deforms upon contact with a tire sidewall to bias bristles on the resilient member into forceful contact with a moving tire sidewall. A brush assembly is disclosed which supports the present brush structure for movement toward and away from a vehicle wheel assembly and also serves to oscillate the brush against the tire sidewall.

Abstract: An apparatus including a brush assembly positionable toward and away from a vehicle wheel which assembly cleans the vehicle tire sidewall by oscillatory brush motion. A base supports extensible carrier means on which the brush assembly moves while actuators impart outward and inward movement to the brush assembly. Continuous means regulates the travel of the telescopic carriers to obviate any tendency of same to bind. A wheel brush cleans the metal wheel and hub cap of each wheel assembly.
