Document Type and Number:
WIPO Patent Application WO/2020/059872
Kind Code:
A1
Abstract:
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 tanδ of the material, the maximum value of tanδ occurs between 20ºC and 70ºC inclusive.
