Tire and manufacturing method for same

Abstract

Provided is a tire having a circular tire frame formed of at least a thermoplastic resin material, in which the tire includes a reinforcing cord member that forms a reinforcing cord layer on an outer circumference of the tire frame, and the thermoplastic resin material contains at least a polyester-based thermoplastic elastomer.

What is claimed is: 
     
         1 . A tire comprising a circular tire frame formed of a thermoplastic resin material, the thermoplastic resin material including:
 a polyester-based thermoplastic elastomer (A) including: a hard segment including a polyester resin; and a soft segment; and   a polyester resin (B) other than a thermoplastic elastomer.   
     
     
         2 . The tire according to  claim 1 , wherein an elastic modulus of the polyester resin (B) is 700 MPa or greater. 
     
     
         3 . The tire according to  claim 1 , wherein a mass ratio (A:B) of the polyester-based thermoplastic elastomer (A) and the polyester resin (B) other than a thermoplastic elastomer is from 95:5 to 50:50. 
     
     
         4 . The tire according to  claim 1 , wherein a content of the polyester-based thermoplastic elastomer (A) in the thermoplastic resin material is from 50% by mass to 95% by mass. 
     
     
         5 . The tire according to  claim 1 , further comprising a reinforcing cord member that is wound around an outer circumference of the tire frame in a circumferential direction and forms a reinforcing cord layer.
