摘要：<p>Tyre (1) comprising a crown (2) surmounted radially on the outside by a tread (20) and extended on each side by lateral parts each comprising a sidewall (3) ending in a bead (4) designed to collaborate with a mounting rim of the tyre, each bead (4) comprising at least one circumferential reinforcement (6), this tyre comprising a carcass reinforcement (5) anchored at each of its two ends in a bead by being turned up around the circumferential reinforcement (6) to form a turn-up (51), this carcass reinforcement (5) extending into the sidewalls (3) and into the crown (2) of the tyre and being surmounted radially on the outside by a crown reinforcement (7), this tyre comprising in at least one of its lateral parts at least one cavity (8, 8', 8") in fluidic communication with the outside of the tyre, each cavity (8, 8', 8") having a volume suited to forming a Helmholtz resonator calibrated to attenuate the road noise of the tyre at least in part, this tyre being such that each cavity (8, 8', 8") that forms a Helmholtz resonator in at least one of the lateral parts of the tyre is arranged in the circumferential direction and filled with an open-cell cellular material.</p>
