Abstract: A pneumatic vehicle tire is provided. The tire includes a tread, an inner surface lying opposite the tread, a self-sealing sealant and a sound-absorbing open-cell foam ring arranged inside the pneumatic vehicle tire. The foam ring is adhesively attached to the inner surface and adheres to the self-sealing sealant which is applied before the sound-absorbing open-cell foam ring is attached to the inner surface.

Abstract: A wheel assembly for a surface vehicle is presented. The wheel assembly comprises a tire comprising an envelope structure which by its inner surface encloses a cavity. The envelope structure comprises an outer, surface-engaging side having a circumferential surface, and opposite side walls which are integral with and extend from the surface-engaging side.
