  • Patent number: 4258776
    Abstract: A retreaded belted tire and a method and apparatus for use in preparing same. The tire is prepared for retreading by removing a portion of the existing crown area rubber material so as to leave not greater than a predetermined amount of rubber material lying radially outward of the belt structure. New tread rubber material of uniform thickness throughout its length and width is added to the prepared tire and the assembly is cured under heat and pressure. When the newly added tread material is unvulcanized rubber, the assembly is cured in a mold having a crown area profile complementary to that of the prepared tire.
