A thermoplastic elastomer composition of a structurenof a thermoplastic resin (A) in which a rubberncomposition (B) is dispersed, where the stress at thentime of 2.5% elongation of the stress-strain curve of thenthermoplastic elastomer composition is 0.1 to 50 MPa andnthe ratio of the stress (M 200 ) at -20°C and 200%nelongation and the stress (M 100 ) at -20°C and 100%nelongation is 1.0 < M 200 /M 100 < 2.0, particularly anthermoplastic elastomer composition structured with thenpolyamide resin of the thermoplastic resin (A) in whichnthe rubber composition (B) is dispersed, includes anpolyamide plasticizer (C1) and/or a thermoplasticnelastomer (C2), the ratio of composition being (A) 15 ton59% by weight, (B) 40 to 70% by weight (C1+C2), and 1 ton30% by weight and a tire using the same. |
