Abstract: This disclosure relates to a method of retreading a tire by inserting a tire and an annular bladder between a pair of open matrices with marginal portions of the bladder projecting beyond beads of the tire and resting upon peripheral edge portions of axially opposed bead aligner wheels; the annular bladder being disposed within the tire; inflating the bladder to form an annular vacuum gap between an annular terminal edge of each bladder marginal portion, an annular outboard portion of each bladder and opposing annular portions of the bead aligner wheel peripheral edge portions; radially foreshortening the tire by moving the bead aligner wheels away from each other while the tire is held thereon by the bladder, and thereafter closing the matrices, and further inflating the bladder to urge the tire into intimate conformity with the matrices.

Abstract: 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.
