The present invention relates to a tire, which is substantially a toroidal-shaped carcass structure (CS), with opposite side edges coupled to a right-handed and left-handed bead structure, respectively, A carcass structure (CS) comprising at least one bead core (BC) and at least one bead filler (6); and a belt structure (7) disposed radially outside the carcass structure A tread band (TB) that is radially overlapped on the belt structure; and a pair of side walls (SW) that are disposed on opposite sides of the carcass structure; One bead core (BC): at least one first elongated element (21, 3) comprising at least one composite material comprising a plurality of elongated fibers embedded in a polymer material. Wherein the composite material has a first elongated element (21, 30) having a flexural modulus measured at 23 ° C. according to ASTM standard D790-03 of 10 GPa or more, preferably 20-200 GPa; At least one second elongated element comprising one metal wire. |
