1. A pneumatic tyre (1) comprising:
a toroidal carcass (2), which comprises a body ply assembly (3) of at least one body ply that is partially folded onto itself and therefore having two lateral flaps, within each of which an edge (19) of the body ply assembly (3) rests against an intermediate portion of the body ply assembly (3) itself;
two annular beads (4), each of which is surrounded by the body ply assembly (3) including a respective one of the two lateral flaps and has a bead core (5) and a bead filler (6);
an annular tread (7);
a tread belt (8) comprising at least one tread ply (9);
a pair of sidewalls (11) each arranged externally to the body ply assembly (3) between the tread (7) and a respective one of the two annular beads (4);
a pair of abrasion gum strips (12) each arranged externally to the body ply assembly (3), extending radially more to the inside of a respective one of the pair of sidewalls (11), and at the respective one of the two annular beads (4);
an innerliner (10) which is impermeable to air and arranged internally to the body ply assembly (3); and
a transponder (13) which is arranged in contact with the body ply assembly (3) so that a portion of the transponder (13) is radially at a same level as the edge (19) of one of the two flaps of the body ply assembly (3);
wherein the transponder (13) is arranged between the body ply assembly (3) and the innerliner (10) and therefore the transponder (13) is laterally bordering and in direct contact with the body ply assembly (3) on the external side and is laterally bordering and in direct contact with the innerliner (10) on the inner side; and
wherein a first radial distance (D1) of less than 7 mm is provided between a radially external end of the transponder (13) and the edge (19) of the body ply assembly (3) and a second radial distance (D2) of less than 7 mm is provided between a radially inner end of the transponder (13) and the edge (19) of the body ply assembly (3).
