• and
• sidewalls laterally applied to opposite sides of the carcass structure;
• wherein the carcass structure comprises:
• at least one first carcass ply;
• at least one second carcass ply;
• and
• a pair of annular reinforcing structures engaged close to respective inner-circumferential edges of the carcass plies;
• wherein the at least one first carcass ply and the at least one second carcass ply are formed of strip sections extending in a substantially U-shaped conformation,
• wherein the strip sections comprise at least two thread elements longitudinally arranged parallel to each other,
• wherein the at least two thread elements are at least partly coated with at least one layer of elastomer material,
• wherein the at least one first carcass ply comprises a first series and a second series of strip sections arranged in mutually-alternating sequence along a circumferential extension of the carcass structure,
• wherein the at least one second carcass ply comprises a third series and a fourth series of strip section arranged in mutually-alternating sequence along the circumferential extension of the carcass structure,
• wherein each of the annular reinforcing structures comprises:
• a first primary portion;
• and
• a second primary portion;
• wherein the first primary portion comprises an axially-inner side turned towards end flaps of the strip sections of the first series and an axially-outer side turned towards end flaps of the strip sections of the second series, and
• wherein the second primary portion comprises an axially-inner side turned towards end flaps of the strip sections of the third series and an axially-outer side turned towards end flaps of the strip sections of the fourth series.
