The present disclosure relates to a tire (1) including a sealant layer (2) and a sound-absorbing material layer (3); the sealant layer (2) is disposed between the inner surface of the tire and the sound-absorbing material layer (3) and includes a sealant for adhering the sound-absorbing material layer to the inner surface of the tire (1). The sound-absorbing material layer (3) includes a first porous material having an average pore size of 1200 to 2400 µm.The tire has noise reduction performance while enabling a self-sealing operation to be carried out when a tire puncture occurs by adhering a sound-absorbing material layer to a sealant layer applied to an inner surface of the tire, improves flowability of the sealant by increasing average pore size of a sound-absorbing material, thereby reducing specific surface area between the sealant and the sound-absorbing material, and prevents fine pieces of the sound-absorbing material from deteriorating function of the sealant and can also maintain noise reduction performance by decreasing adhesion specific surface area between the surface of the nail and the sound-absorbing material even when a nail reaches the sound-absorbing material by penetrating the tire and the sealant.
