A tire comprising a crown, two sidewalls and two beads with an axis of revolution and a carcass reinforcement with two carcass plies, each anchored in each bead, each bead comprising:
- a bead wire;
- a part of a first carcass ply extended by a turn-up around the bead wire of the first carcass ply such that the end of the turn-up is situated axially and radially on an outside relative to the bead wire;
- a filler arranged radially on the outside relative to the bead wire and axially between the first carcass ply and the turn-up;
- a part of a second carcass ply arranged axially on the outside relative to the first carcass ply, to the filler and to the turn-up;
- a protective rubber and a sidewall rubber axially furthest toward the outside and forming a first interface between the protective rubber and the sidewall rubber;
- and
- a communication module comprising a radiofrequency transponder with an electronic chip and a helical radiating antenna,
- wherein an additional filler is positioned axially between the second carcass ply and the cushion gum and the sidewall rubber,
- wherein a radially outer end of the additional filler extends radially further than a radially outer end of the filler,
- wherein the communication module is positioned at a second interface between the second carcass ply and the additional filler,
- wherein, with the turn-up having an end situated radially below the radially outer end of the filler, the communication module is positioned radially at a level of the end of the filler, and
- wherein a radially outermost end of the first interface between the protective rubber and the sidewall rubber extends radially on the outside to the communication module.
