US 10,471,781 B2 · Pneumatic vehicle tire

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. The self-sealing sealant has, at least immediately after being applied, a tackiness required for an adhesive attachment of the sound-absorbing open-cell foam ring. A closed-cell material ring is arranged between the sound-absorbing foam ring and the self-sealing sealant to prevent a diffusion of the sealant into the open-cell foam ring. The closed-cell material ring effects an airtight condition.
