Abstract: A pneumatic tyre comprising an inner surface of the tyre, wherein a sound absorbing device component is connected to the inner surface of the tyre. The sound absorbing device component comprises a panel with a plurality of perforations and two sidewall sections, the sidewall sections being distinct from the panel, wherein the sidewall sections are connected to the inner surface of the tyre and arranged opposite of each other and wherein the panel is borne by the sidewall sections, thereby positioning the panel at a distance from the inner surface of the tyre and defining an inner volume enclosed by the panel, the sidewall sections and the inner surface. Furthermore, ≥95 area-% of all perforations which permit access to the inner volume are located on the panel.
