Tire comprising sealant layer and sound-absorbing material layer

Abstract

The present invention relates to a tire including a sealant layer and a sound-absorbing material layer, and the tire includes a sound-absorbing material layer located on the inner surface of the tire, and a sealant layer disposed between the inner surface of the tire and the sound-absorbing material layer, and applied on the inner surface of the tire, wherein the sound-absorbing material layer includes a first porous material having closed cells, and a second porous material having open cells, so that the tire may self-seal in the event of a puncture by including the sealant layer applied on the inner surface of the tire, may have noise reduction performance by including the sound-absorbing material, and even if a nail penetrates the tire and sealant and reaches the sound-absorbing material, may prevent fine fragments of the sound-absorbing material from degrading the function of the sealant and maintain the noise reduction performance.
