摘要： In building a tyre (1), in particular for two-wheeled vehicles, formation of annular stiffening inserts (10) is provided which are incorporated in the carcass structure (2), each close to one of the sidewalls (9). Each annular stiffening insert (10) is made up of a cord of the 3x3x0.175 HE HT type, wound up into coils (10a) disposed radially in side by side relationship with each other, starting from the annular reinforcing structures (4) arranged in the beads until close to a side edge (5a) of the belt structure (5).

摘要： Formation of a belt structure (2) takes place by laying down, directly on the carcass structure (3) of a tyre being processed (1), a laying layer (16) formed of a continuous strip-like element (16) of elastomer material directly coming from an extrusion die. The strip-like element (16a) has a differentiated thickness at its opposite edges to give rise to circumferential grip recesses (18) on the laying layer (16). Then, on the laying layer (16) a primary belt strip (6) is formed which is obtained by winding up of a continuous bare cord into coils (6a) disposed in axial side by side relationship. A cord of the high starting elongation type is preferably employed and it is wound up substantially in the absence of tensioning. A covering layer (19) made in the same manner as the laying layer (16) can be subsequently laid down on the primary belt strip (6).

摘要： Tire for vehicle wheels, comprising metallic reinforcing cords made of a single strand of elementary filaments preformed by sinusoidal waving and wound together. Said metallic cords show a value of the integral of the breaking stress not lower than 5000 J/m3.
