a method for molding articles , particularly tires , of different diameters / circumferences including a plurality of pitches defining a mold cavity , the pitches having transverse faces in generally face - to - face abutment in a closed position of the mold cavity , and at least several of the pitches being of different lengthwise sizes . the pitches in the closed position of the mold cavity defining a predetermined mold configuration which includes portions at angles to the length of the article molded in the mold cavity . the mold configuration matches lengthwise across all of the transverse faces irrespective of the location of the pitches relative to each other and irrespective of the number of the pitches . the latter arrangement permits articles , such as new or retread tires , of different lengths but of the generally same predetermined mold configuration to be molded in a single mold .
