Abstract

Provided is a tire having at least a circular tire frame formed of a thermoplastic resin material, the tire including a reinforcing cord member that forms a reinforcing cord layer on the outer circumference of the tire frame, and the thermoplastic resin material including at least a polyamide-based thermoplastic elastomer.

Claims

exact text as granted — not AI-modified

1 . A tire comprising at least a circular tire frame formed of a thermoplastic resin material,
 the thermoplastic resin material including
 a polyamide-based thermoplastic elastomer, and 
 an acid-modified elastomer obtained by acid-modifying a thermoplastic elastomer other than the polyamide-based thermoplastic elastomer, or a mixture of a thermoplastic elastomer other than the polyamide-based thermoplastic elastomer and an acid-modified elastomer obtained by acid-modifying the elastomer other than the polyamide-based thermoplastic elastomer. 
   
     
     
         2 . The tire according to  claim 1 , wherein the acid value of the thermoplastic resin material is equal to or greater than 0.1 mg-CH 3 ONa/g but less than 2.2 mg-CH 3 ONa/g. 
     
     
         3 . The tire according to  claim 1 , wherein the ratio of the mass of the polyamide-based thermoplastic elastomer and the total mass of the thermoplastic elastomer other than the polyamide-based thermoplastic elastomer and the acid-modified elastomer (the mass of the polyamide-based thermoplastic elastomer:the total mass of the acid-modified elastomer and the thermoplastic elastomer other than the polyamide-based thermoplastic elastomer) in the thermoplastic resin material is from 90:10 to 60:40. 
     
     
         4 . The tire according to  claim 1 , wherein the content of the polyamide-based thermoplastic elastomer in the thermoplastic resin material is 55 mass % to 95 mass %.
