  "textContent": "The present invention provides a pneumatic tyre provided with a noise damper in the tyre cavity, which can maintain high-speed durability and producibility while also reducing cavity resonance. The present invention provides a pneumatic tyre comprising a tread having a width TW in contact with the ground during travel, in which a noise damper made of a sound-absorbing material is attached to the tyre internal surface in order to reduce cavity resonance, wherein the noise damper is at least one continuous ribbon made of a sound-absorbing material and having a width W and a thickness E, which is fixed over an attachment width Wc to the tyre internal surface over a range of at least 30% of the inside of the tread in the radial direction, the start end and terminal end which are the two ends of the continuous ribbon are disposed in such a way as to be offset from each other in the axial direction, and the continuous ribbon forms, together with the tyre internal surface, a continuous groove having a groove width D which is at least equal to 10% of the width W of the continuous ribbon.",
