    摘要: In a pneumatic tire, a partial tie rubber layer is disposed between a carcass layer and an innerliner layer in a limited manner across an entire region excluding end portions near a pair of bead portions; end surfaces on both sides in a tire lateral direction of the partial tie rubber layer are inclined surfaces that form an acute angle with respect to a surface of the partial tie rubber layer on the carcass layer side; and an inclination angle of the inclined surfaces with respect to the surface of the partial tie rubber layer on the carcass layer side is from 20° to 60°.

    摘要: The invention relates to a tire comprising a circumferential tread having an outer tread surface and an inner innerliner surface; at least two spaced-apart beads; sidewall portions extending between the tread and the beads; and a belt-like foam noise damper having first and second terminal ends, wherein the noise damper lines the innerliner surface; wherein the noise damper is secured to the innerliner surface via an adhesive situated between the noise damper and the innerliner, wherein the terminal ends of the noise damper are cut at an angle of less than 90 degrees, overlap each other, and the overlapped second terminal end of the foam is joined to the first terminal end by the adhesive present underneath the second terminal end, and wherein the adhesive has weight in the range of 30 to 800 grams per square meter of foam surface.

    摘要: A pneumatic tire for resonance noise reduction, which includes a plurality of resonance noise-reducing members that are disposed along the circumferential direction of the inner liner of a tire, and are formed to protrude from the inner liner so as to reduce the interference of the resonance noises generated inside the tire. The resonance noise-reducing members are formed at an irregular interval of disposition along the circumferential direction of the inner liner.
