发明名称 Pneumatic tire and manufacturing method therefor
摘要 Provided is a pneumatic tire and a manufacturing method therefor which allow a reduction in a cavity resonance sound without complicated manufacturing steps. A pneumatic tire of the present invention includes: a pair of bead portions; a carcass layer bridged between the pair of bead portions; and an inner liner layer disposed at a tire inner surface side of the carcass layer, the inner liner layer being made of a thermoplastic resin or a thermoplastic elastomer composition obtained by blending a thermoplastic resin with an elastomer. The inner liner layer has a laminated structure including multiple film layers having different melting points of the thermoplastic resin from each other. The film layer having the lowest melting point of the thermoplastic resin is foamed to form multiple convex portions in the tire inner surface.
