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