Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a run flat tire improving run flat traveling performance while maintaining usual traveling performance at filling of an internal pressure to a high level. SOLUTION: In the run flat tire, at least one of radial carcass ply layers includes a cord of a polyolefin-ketone fiber substantially comprising a repeating unit represented by general formula (1) and a side wall is reinforced by a reinforcement rubber layer. Preferably, in the run flat tire, a steel insert is inserted to the side wall. COPYRIGHT: (C)2007,JPO&INPIT |
