ABSTRACT:
A vehicle tire with protruding nibs rolls down a ramp and into the device and begins to be rotated thereby. Knife means facing into the direction of rotation of the tire are skimmed over the left sidewall, the tread, and the right sidewall of the rotating tire at least once to trim off the nibs. Then paint is preferably sprayed upon the tire sidewalls, whereupon the processed tire is ejected from the device by application of brake means, preferably in combination with bumping the tire being ejected from the rear with another tire entering the device for processing. Cycling of the device may be automatically controlled. In the spray-painting operation, black paint may be applied to one sidewall as white wall protector is applied to the other.
