This disclosure is directed to a mold particularly adapted for applying pre-cured tread rubber to a tire, the mold including a pair of generally annular mold bodies which collectively define a chamber adapted to receive a tire, the mold bodies being capable of relative axial adjustment whereby axial dimensions of the chamber may be varied to accomodate tires of different widths, an annular band for locking the mold bodies to each other at a particular position of axial relative adjustment, and axially shiftable means for maintaining the mold bodies at a desired position of relative axial adjustments. Preferably an annular resilient rubber or like envelope surrounds the tire as well as its sidewalls to prevent steam or an equivalent heating medium from permeating between the tire and the pre-cured rubber glue thereto.
A mold particularly adapted for applying pre-cured tread rubber to tires of different widths comprising a pair of generally annular mold bodies which collectively define a chamber adapted to receive a tire, said annular mold bodies being capable of relative axial movement whereby an axial dimension of said chamber may be selectively adjusted to accommodate tires of different widths, means for locking said annular mold bodies to each other at any one of a plurality of positions of relative axial adjustment between said mold bodies, axially movable axial adjustment means for selectively adjusting the axial dimension of said chamber, said axial adjustment means being carried by one of said annular mold bodies, and said axial adjustment means when selectively adjusted to accommodate a particular tire width has a terminal end face resting upon another of said annular mold bodies.
