A pneumatic tyre comprising: a toroidal carcass, which consists of a body ply that is partially folded onto itself and therefore having two lateral flaps, within each of which an edge of the body ply rests against an intermediate portion of the body ply itself; two annular beads, each of which is surrounded by the body ply and has a bead core and a bead filler; an annular tread; a tread belt comprising at least one tread ply; a pair of sidewalls arranged externally to the body ply between the tread and the beads; a pair of abrasion gum strips arranged externally to the body ply, radially more to the inside of the sidewalls, and at the beads; an innerliner which is impermeable to air and is arranged within the body ply; and a transponder which is arranged in contact with the body ply at a flap of the body ply, the pneumatic tire being characterized in that the transponder is entirely located between the edge of the body ply and an edge of the bead filler, in such a way that a radially outer end of the transponder is arranged radially more to the inside of the edge of the body ply and a radially inner end of the transponder is arranged radially more to the external of the edge of the bead filler; wherein each flap of the body ply terminates radially below the tread ply in such a way that within each flap of the body ply the edge of the body ply is below the tread ply; wherein the transponder is arranged between the body ply and the innerliner and therefore the transponder is laterally bordering and in direct contact with the body ply on the external side and is laterally bordering and in direct contact with the innerliner on the inner side; a first radial distance greater than 7 mm is provided between the radially external end of the transponder and the edge of the body ply; and a second radial distance greater than 7 mm is provided between the radially internal end of the transponder and the edge of the bead filler. a toroidal carcass, which consists of a body ply that is partially folded onto itself and therefore having two lateral flaps, within each of which an edge of the body ply rests against an intermediate portion of the body ply itself; two annular beads, each of which is surrounded by the body ply and has a bead core and a bead filler; an annular tread; a tread belt comprising at least one tread ply; a pair of sidewalls arranged externally to the body ply between the tread and the beads; a pair of abrasion gum strips arranged externally to the body ply, radially more to the inside of the sidewalls, and at the beads; an innerliner which is impermeable to air and is arranged within the body ply; and a transponder which is arranged in contact with the body ply at a flap of the body ply, the pneumatic tire being characterized in that the transponder is entirely located between the edge of the body ply and an edge of the bead filler, in such a way that a radially outer end of the transponder is arranged radially more to the inside of the edge of the body ply and a radially inner end of the transponder is arranged radially more to the external of the edge of the bead filler; wherein each flap of the body ply terminates radially below the tread ply in such a way that within each flap of the body ply the edge of the body ply is below the tread ply; wherein the transponder is arranged between the body ply and the innerliner and therefore the transponder is laterally bordering and in direct contact with the body ply on the external side and is laterally bordering and in direct contact with the innerliner on the inner side; a first radial distance greater than 7 mm is provided between the radially external end of the transponder and the edge of the body ply; and a second radial distance greater than 7 mm is provided between the radially internal end of the transponder and the edge of the bead filler.
