    摘要： A pneumatic tire with a surface fastener having engagement elements that are prevented from being crushed during curing, and a method of producing such a pneumatic tire. Uncured rubber is filled between the engagement elements of the surface fastener to form a protective rubber layer in which the engagement elements are buried. Then, the surface fastener having the protective rubber layer is placed on an uncured tire so that the surface opposite the surface having the engagement elements is in intimate contact with the inner surface of the tire, and after that the uncured tire having the surface fastener is cured by a curing machine equipped with a bladder.

    摘要： There is provided a tire noise reduction device and a pneumatic tire, in which weight can be reduced while sound absorbing characteristics are maintained and durability is improved.
    The tire noise reduction device 1A of the present invention includes a sound absorbing member 3 of flexible polyurethane foam to be attached to an inner surface of a tire facing a cavity of the tire. The sound absorbing member 3 comprises a first sound absorbing layer 3A placed on a tire inner surface side thereof. The first sound absorbing layer 3A has a tear strength (N/cm) per unit density (kg/m 3 ) which is equal to or more than 0.30. The second sound absorbing layer 3B has a density which is lower than that of the first sound absorbing layer 3A.

    摘要： A tire noise reduction device and pneumatic tire capable of being reduced in weight with their sound absorption performance maintained and their durability improved. The tire noise reduction device (1A) has a sound absorption member (3) made of soft polyurethane foam and is installed on a tire inner surface (14) facing a tire cavity section (15). The sound absorption member (3) is formed by layering a first sound absorption layer (3A) placed on the tire inner surface side and a second sound absorption later (3B) placed on the opposite side of the tire inner surface. Tearing strength (N/cm) per unit density (kg/m3) of the first sound absorption layer (3A) is not less than 0.30. The second sound absorption layer (3B) has a lower density than the first sound absorption layer (3A).
