Abstract (en)
[origin: WO2019092631A1] A method for the construction of a pneumatic tyre (1) having a pair of annular inserts (13) arranged on the opposite sides of a carcass (2), internally to a body ply (3), manufactured from a polymer foam matrix and provided with a respective inner surface (14) facing the body ply (3); the method provides applying an innerliner (11) to the body ply (3); wrapping the body ply (3) provided with the innerliner (11) around a forming drum in order to obtain a green pneumatic tyre (1); vulcanizing the green pneumatic tyre (1) within a mold in order to obtain a semi-finished pneumatic tyre (1); producing the inserts (13) independently and separately from the semi-finished pneumatic tyre (1); and connecting the internal surfaces (14) of each insert (13) to the innerliner (11) or else to the body ply (3) in order to obtain a finished pneumatic tyre (1).
