Present invention provides a tire (1) intended to be mounted on a mounting rim, the tire comprising a summit (2) surrounded on both sides by sidewalls (3) terminating in beads (4) provided to cooperate with the mounting rim of the tire, the tire comprising a carcass reinforcement (5) extending in the summit and the sidewalls, and anchored at its two ends in the beads, the carcass reinforcement being surmounted radially on the outside by a summit reinforcement (6) composed of a plurality of reinforcing plies (61, 62, 63), said summit reinforcement being surmounted radially on the outside by a tread (10) intended to come into contact with a ground during use of the tire, the tire comprising in its summit, at least one cavity (1 1) acting as a resonator and in fluid communication with the outside of the tire, when the tire is mounted onto a mounting rim each cavity (1 1) having an appropriate volume to form a calibrated resonator to attenuate the noise in a frequency range between 500 and 2000 Hz, the tire being characterized in that each cavity (11) is arranged substantially uniformly in the circumferential direction and is filled with a fibrous or a filamentary material. |
