Abstract
A thermoplastic elastomer composition of a structure of a thermoplastic resin (A) in which a rubber composition (B) is dispersed, where the stress at the time of 2.5% elongation of the stress-strain curve of the thermoplastic elastomer composition is 0.1 to 50 MPa and the ratio of the stress (M ) at −20° C. and 200% elongation and the stress (M ) at −20° C. and 100% elongation is 1.0<M /M <2.0, particularly a thermoplastic elastomer composition structured with the polyamide resin of the thermoplastic resin (A) in which the rubber composition (B) is dispersed, includes a polyamide plasticizer (C1) and/or a thermoplastic elastomer (C2), the ratio of composition being (A) 15 to 59% by weight, (B) 40 to 70% by weight (C1+C2), and 1 to 30% by weight and a tire using the same.
