Abstract:
A motorcycle tire, for motor-vehicle wheels, comprising:a carcass structure having at least one carcass ply with circumferential end edges which are turned back around two bead cores;a belt structure having a high transverse curvature extending circumferentially about said at least one carcass ply and having at least one circumferentially inextensible cord wound in a plurality of circumferential coils disposed side by side according to a curvilinear transverse profile;a tread band applied circumferentially over the belt structure;an auxiliary support element of elastomeric material. said at least one inextensible cord being wound on said auxiliary support element, said auxiliary support element consisting of a sheet interposed between the belt structure and carcass ply and shaped according to the transverse-curvature profile of the layer formed by said coils, whereinfibrillose fibers are homogeneously distributed in the elastomeric material of said sheet for increasing the stretchability of said elastomeric material without substantially altering adhesiveness thereof during manufacturing of said tire, when said material is in a raw state.
