<P>PROBLEM TO BE SOLVED: To provide a tire which is made of a thermoplastic polymeric material, has high elasticity and a low loss factor, and is superior in heat resistance. <P>SOLUTION: The tire 10 has an annular tire case 17 made of a polyamide-based thermoplastic resin and a resin material containing a resin whose glass transition temperature (Tg) is higher than that of the polyamide. The glass transition temperature of the resin is 20°C or more higher than that of a hard segment of the thermoplastic elastomer. A mass ratio (x+y: z) between a total mass (x+y) of the hard segment (x) of the thermoplastic elastomer and the resin (y) and a mass of a soft segment (z) of the thermoplastic elastomer is 10:90 to 90:10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
