Abstract: Tyre for vehicle wheels having a carcass structure shaped in a substantially toroidal configuration, the opposite lateral edges of which are associated with respective right-hand and left-hand bead wires to form respective beads; a belt structure applied in a radially external position with respect to the carcass structure; a tread band radially superimposed on the belt structure; at least one layer of crosslinked elastomeric material applied in a radially internal position with respect to the tread band; a pair of sidewalls applied laterally on opposite sides with respect to the carcass structure, wherein the at least one layer of crosslinked elastomeric material has a dynamic elastic modulus, measured at 70° C., not lower than 20 MPa, preferably 25 MPa to 50 MPa; a ratio between tensile modulus at 100% elongation and tensile modulus at 10% elongation not lower than 1.5, preferably 2 to 5.

Abstract: A pneumatic tyre includes a pair of axially-spaced-apart annular reinforcing elements and bead fillers, a carcass structure, at least one flipper, a tread band, a belt structure, and at least one pair of sidewalls. The carcass structure includes at least one carcass ply, extends between the annular reinforcing elements, and is secured at axially opposite end portions to respective annular reinforcing elements. Each end portion is turned up around the respective annular reinforcing element. Each bead filler is disposed radially outward of the respective annular reinforcing element. The at least one flipper at least partially envelops an associated annular reinforcing element and bead filler and includes a plurality of first elongated reinforcing elements that are substantially parallel to each other. The first elongated reinforcing elements include at least one preformed metallic element having a diameter greater than or equal to 0.05 mm and less than or equal to 0.25 mm.

Abstract: A tyre includes a carcass, a belt structure, and a tread band. The belt structure includes at least two belt plies and at least one belt layer radially external to the belt plies. The at least one belt layer extends at least for an axial width of the at least two belt plies and includes at least one first elongated element and at least one second elongated element. The elongated elements form turns substantially oriented in a circumferential direction of the tyre. The turns are alternately disposed along an axial development of the at least one belt layer. The at least one first elongated element is a hybrid cord including at least one high-elastic-modulus filament and at least one low-elastic-modulus filament that are twisted together. An elastic modulus of the at least one second elongated element is lower than an elastic modulus of the at least one first elongated element.
