    摘要： A tread for bonding to a tire carcass to form a retreaded tire having a length, a width, a top side and a bottom side. The tread also includes a central portion and a pair of wing portions extending laterally from the central portions. The top sides of each wing portion include one or more discontinuities having a longitudinal component and configured to resist deflection when subjected to a force from the bottom side and to deflect downwardly when subjected to a force from the top side. In particular embodiments, the one or more discontinuities are arranged within each wing portion are arranged within a thickened portion of each wing portion.

    摘要： A method for the cold retreading of a tyre (1) comprising the following steps: a removal step, during which the old, worn tread is removed from the tyre in order to expose an equatorial surface (2) of a casing (3) of the tyre (1); a deposition step, during which a cushion (4) and a pre-cured tread strip (6) provided with a tread pattern are deposited around the equatorial surface (2) of the casing (3); and a curing step, during which the cushion (4) arranged between the casing (3) and the pre-cured tread strip (6) is cured. The cushion (4) is manufactured with a compound comprising 1 to 30 phr of at least one conductive material chosen among graphite, graphene and a carbon black having a surface area which is greater than or equal to 300 m2/gr. The curing step comprises a connection step, during which said cushion (4) is connected to a heat or power source (S).

    摘要： The invention includes methods of forming a retreaded tire, and treads there for. Particular embodiments of such methods provide a tire carcass configured to receive the tire tread along an annular tread-receiving area and a pre-cured tire tread including a tread body and a detachable connector. The connector is arranged within a thickness of the tread between a top void portion and a bottom void portion and extending across a width of the top void portion and of the bottom void portion. The detachable connector is configured to separate from the tread upon application of a separation force. Further steps include assembling a retreaded tire by arranging the tire tread atop a bonding layer arranged between the tire tread and the tire carcass, bonding the tire tread to the tire carcass, and removing the detachable connector from the top void portion after the step of bonding.
