Tyre intended to be mounted on a drop-centre rim "15° drop centre", comprising a radial carcass reinforcement, made up of a single carcass reinforcement layer formed of reinforcing elements inserted between two skim layers of rubber compound, said tyre comprising a crown reinforcement , itself radially capped by a tread , said tread being connected to two beads by two sidewalls, the layer of reinforcing elements of the carcass reinforcement being anchored in each of the beads by being turned up around a bead wire to form a main part of the carcass reinforcement layer , extending from one bead wire to the other, and a turn-up of the carcass reinforcement layer in each of the beads , said turn-up of the carcass reinforcement layer being separated from the main part of the carcass reinforcement layer by a first layer of rubber compound extending radially from the bead wire to beyond the end of the turn-up of the carcass reinforcement layer, and said turn-up of the carcass reinforcement layer being, axially towards the outside, in contact with a second layer of rubber compound , itself at least in contact with a third layer of rubber compound that forms the exterior surface of the tyre in the region of the bead , said third layer of rubber compound notably being intended to come into contact with the rim, said third layer of rubber compound being, radially towards the outside, in contact with a fourth layer of rubber compound that forms the exterior surface of said sidewall in meridian section of said tyre : - the distance between the end of the turn-up of the carcass reinforcement layer and the radially innermost point (A) of the circle circumscribed on the bead wire is between 45 and 90% of the distance between the axially outermost point (E) of the main part of the carcass reinforcement layer and the radially innermost point (A) of the circle circumscribed on the bead wire , - the turn-up of the carcass reinforcement layer and the main part of the carcass reinforcement layer are the only layers of reinforcing elements of which the elongation at break is less than 6% that are present in a sidewall region making up at least 90% of the region comprised between the end of the turn-up of the carcass reinforcement layer and the radially outermost point (B) of the bead wire , said tyre being characterized in that - a radiofrequency communication module is positioned in the bead at the interface between the second and third layer of rubber compound and radially on the outside relative at a distance greater than 25 mm from the radially outermost point (B) of the bead wire . - the distance between the end of the turn-up of the carcass reinforcement layer and the radially innermost point (A) of the circle circumscribed on the bead wire is between 45 and 90% of the distance between the axially outermost point (E) of the main part of the carcass reinforcement layer and the radially innermost point (A) of the circle circumscribed on the bead wire , - the turn-up of the carcass reinforcement layer and the main part of the carcass reinforcement layer are the only layers of reinforcing elements of which the elongation at break is less than 6% that are present in a sidewall region making up at least 90% of the region comprised between the end of the turn-up of the carcass reinforcement layer and the radially outermost point (B) of the bead wire , - a radiofrequency communication module is positioned in the bead at the interface between the second and third layer of rubber compound and radially on the outside relative at a distance greater than 25 mm from the radially outermost point (B) of the bead wire . <EOS>
