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 retreading method also comprises a conductive interposition step, during which a conductive adhesive compound (5) is deposited between said cushion (4) and said pre-cured tread strip (6) and/or between said cushion (4) and said casing (3). The conductive adhesive compound (5) comprises at least one conductive material in a quantity ranging from 5 to 20% by weight and chosen among graphene, graphite and a carbon black having a surface area which is greater than or equal to 300 m.sup.2/gr. The curing step comprises a connection operation, during which said conductive adhesive (5) compound is connected either to a heat source (S) or to a power source (S) so as to transmit the heat to the cushion (4).

The method includes the step of passing an electric current through at least one wire that is situated between a carcass of a tire casing and a tread. The method also includes the step of calculating a value of a temperature of the wire as a function of a relative value of the current. The method proceeds with the step of controlling the current as a function of the temperature value calculated.

The invention includes methods for forming a retreaded tire and treads there for. Particular embodiments of such methods include providing a tire carcass configured to receive a tire tread along an annular tread-receiving area and a pre-formed tread comprising a tread body and a submerged void arranged along a bottom side of the tread and extending into the tread thickness to a top end located below the top side of the tread, the submerged void having a length and an opening arranged along the bottom side when the tread is in an uninstalled configuration, where the opening of the submerged void extends in a direction of the submerged groove length along an alternating, non-linear path. 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 and comprising uncured bonding material.
