A tire having a transponder comprises: a crown which has a crown reinforcement with an axial end at each edge, joined at each of its axial ends to a bead, which has an inner end, by a sidewall; a carcass reinforcement which is formed of adjacent first wires and is anchored in each bead around a spiral formed by second wires; the transponder comprising a core defining a first axis, a first cover wire helically wound around the core and an electrical insulation device; and the first cover wire comprising at least two conductive wire elements galvanically connected to an electronic chip comprising a radiofrequency transceiver component. The thickness of the elastomer mixture separating the outer cover wire, which is located furthest outwards from the first axis, and the reinforcements is greater than 0.5 millimeter.
