Tyre for vehicle wheels comprising; a) a carcass structure having at least one carcass ply associated with respective left and right bead wires, each bead wire being enclosed in a respective bead, said bead comprising a bead filler b) a belt structure comprising at least one belt strip applied circumferentially over said carcass structure; c) a tread band circumferentially superimposed on said belt structure; d) a pair of side walls applied laterally on opposite sides relative to said carcass structure; in which said bead filter is obtained by vulcanization of an elastomeric composition comprising discontinuous fibres and at least one elastomeric groups. The abovementioned bead filler is capable of having a positive influence on the performance qualities of the tyre, in particular on the performance qualifies at high speed, such as, for example, the cornering stability, the control on a wet surface and the ride comfort.
