The carcass structure (2) of a tyre comprises at least one carcass ply (3) formed of strip-like sections (13) comprising longitudinal thread-like elements (14) incorporated into a layer of elastomer material (17). The strip-like elements (13) have respective crown portions (24) disposed circumferentially in side by side relationship with each other and side portions (25) radially extending at the tyre sidewalls. The side portions (25) are each at least partly covered with a side portion belonging to an adjoining deposition length. Associated with the carcass ply (3) are annular structures (4) each comprising a pair of inextensible inserts (26, 30) in the form of a crown, between which a turned-back flap (25a) of the carcass ply (3) is interposed, after possible interposition of an elastomeric filling insert (31). A belt structure (5), a tread band (8) and sidewalls (9) may be combined with the carcass structure (2) so as to define a tyre (1). |
