Provided is a tire inner liner with which it is possible to suppress resistance to flex fatigue during tire travel and peeling failures at high temperatures, and also reduce rolling resistance at low temperatures. A tire inner liner comprising a material that contains a thermoplastic elastomer composition, which is constituted from a thermoplastic resin or thermoplastic-resin component and an elastomer component, said tire inner liner characterized in that, in a temperature dependent curve of tan[delta] of the material, the maximum value of tan[delta] occurs between 20 DEG C and 70 DEG C inclusive.
提供可以抑制轮胎行驶时的耐弯曲疲劳性和高温下的剥离故障,可以减少低温下的滚动阻力的轮胎用内衬层。其特征在于,是由包含热塑性树脂或热塑性弹性体组合物的材料形成的轮胎用内衬层,所述热塑性弹性体组合物包含热塑性树脂成分和弹性体成分,在上述材料的tanδ的温度依赖性曲线中在20~70℃之间存在tanδ的最大值。
