ABSTRACT:
A method and apparatus for producing both wing-type and wingless tire treads from a single mold. The mold includes a main portion, a pair of first inserts which are selectively attachable to the main portion. The pair of first inserts is capable of molding wingless treads. A pair of second inserts can be selectively secured to the main portion in place of the first pair of inserts to mold wing-type treads. The method for converting a wingless tire tread mold to a wing-type tire tread mold includes the steps of removing the pair of first inserts from the main portion of the mold and securing the pair of second inserts to the main portion of the mold with the securing apparatus.
