Document Type and Number:
WIPO Patent Application WO/2018/211734
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a tire which exhibits excellent durability and which is obtained using a resin composition whose hardness can be easily adjusted, and a means for solving this problem is a tire in which a resin composition containing at least two types of copolymers comprising a polyamide and a polyether is used in a structural member, the tire being characterized in that among the copolymers, a copolymer (i) having the highest polyamide content and a copolymer (i+1) having the lowest polyamide content satisfy the relationship represented by formula (1): 0 <∣Xi-Xi+1∣ ≤ 40 [in the formula, Xi denotes the difference (Hi-Si) between the content (Hi (mass%)) of the polyamide and the content (Si (mass%)) of the polyether in copolymer (i), and Xi+1 denotes the difference (Hi+1-Si+1) between the content (Hi+1 (mass%)) of the polyamide and the content (Si+1 (mass%)) of the polyether in copolymer (i+1)].
