ABSTRACT:
A tire recapping and retreading method and apparatus that includes a rigid, segmented tread mold. The mold is retained in place over the tire carcass and uncured tread material by a resilient elastic tension band or prestressed metal tension springs. Further retaining force is provided by a resilient envelope to complete the formation of the retread when the tire and apparatus is placed in a hot air oven. The use of the rigid segmented mold described eliminates the distortion of the tire carcass by the mold.
