An automatic spew trimming method wherein a tire is rotated while being supported from an inside to be trimmed by a knife and an apparatus used therefor. The apparatus includes a supply conveyer, a tire rotating section, a cutter for tire tread, a cutter for sidewall, and a discharge conveyer. According to the method and the apparatus of the present invention, even a tire such as a motor cycle tire having low rigidity, small tread width and nearly complete round cross section can be trimmed to cut off spew. Further, even if many kinds of tires of different sizes are supplied at random, they can be satisfactorily accommodated and treated.
