摘要： A tire assembly can include a rim and a pneumatic tire. A sound damper can be in a tire inner cavity, defined by an outer surface of the rim and an inner surface of the pneumatic tire, extending in a tire circumferential direction. The rim can have a rim diameter RD not greater than 18 inches. A ratio SH/SW of a cross-sectional height SH to a tire cross-sectional width SW of the pneumatic tire can be 30% to 45%. A ratio RW/SW of a rim width RW of the rim to the tire cross-sectional width SW can be 78% to 99%. The sound damper can include a sponge material adhered to at least one of the outer surface of the rim and the inner surface of the pneumatic tire. The sponge material can have a volume of not less than 0.4% of a total volume of the tire inner cavity.

摘要： On a pneumatic tire, a sound absorbing member is installed on an inner surface of a tread portion via a surface fastener including a pair including a hook member and a loop member, the hook member including hook-shaped elements on one surface and being fixed to the tire inner surface, and the loop member being provided with loop-shaped elements engageable with the hook-shaped elements and being fixed to the sound absorbing member. In a meridian cross-section, the loop member has at least one section partially fixed in a tire width direction to the sound absorbing member. Given a fixed region in which the loop member is fixed to the sound absorbing member, and a non-fixed region in which the loop member is not fixed to the sound absorbing member, an engaging region in which the loop member and the hook member engage each other is on the non-fixed region.

摘要： The present disclosure relates to a tire including a sealant layer and a sound-absorbing material layer, and the tire includes a sound-absorbing material layer which is adhered to an inner surface of the tire and a sealant layer which is disposed between the inner surface of the tire and the sound-absorbing material layer and includes a sealant for adhering the sound-absorbing material layer to the inner surface of the tire.
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.

摘要： The invention relates to a pneumatic vehicle tyre with a sound-absorbing inner absorber (9) adhesively attached in its interior to the inner surface (7) opposite from the tread (1), wherein the inner absorber (9) adheres to an automatically sealing sealant (8), which at least immediately after being applied has the tackiness required for the adhesive attachment. In order not to influence the flow properties of the sealant disadvantageously and in order to ensure a reliable sealing effect of the sealant, a separating layer (10) is arranged between the sealant (8) and the inner absorber (9) and the separating layer (10) is made in such a way as to ensure a sufficient flowability of the sealant (8) for the sealing and a reliable adhesive attachment of the foam ring (9).
