1. A pneumatic tire comprising:
a toroidal carcass, which comprises a body ply partially collapsed onto itself and therefore having two lateral flaps, in each of which an edge of the body ply rests against an exterior intermediate portion of the body ply itself;
two annular beads, one on each axial side of the tire, each of which occupies the respective space that is surrounded by the body ply and comprises a bead core and a bead filler;
an annular tread;
a pair of sidewalls, one on each axial side of the tire, arranged axially externally to the body ply and extending radially inward from the tread;
a pair of abrasion gum strips, one on each axial side of the tire, arranged at the beads axially externally to the body ply, and extending radially inward from the sidewalls; and
a transponder which is arranged in contact with the body ply at one of the two flaps of the body ply and is located radially more to the inside of the edge of the body ply in the one of the two flaps of the body ply;
wherein the transponder is arranged radially between said edge of the body ply and the bead surrounded by the part of the body ply including said edge of the body ply;
wherein the transponder is arranged axially more to the inside of the sidewall arranged axially externally to the one of the two flaps of the body ply and axially more to the inside of the abrasion gum strip extending radially inward from said sidewall in a zone wherein both said sidewall and said abrasion gum strip are present; and
a radial distance greater than 7 mm is provided between the transponder and said edge of the body ply.
