Abstract
A tire includes a circular tire frame formed of a resin material, the resin material including a polyamide-based thermoplastic elastomer having a weight average molecular weight of from 15,700 to 75,000. Included with the tire may be side portions and a crown portion that serves as an outer peripheral portion that is in communication with the side portions.
Claims1
A tire, comprising a circular tire frame formed of a resin material, the resin material comprising a polyamide-based thermoplastic elastomer having a weight average molecular weight of from 45,000 to 75,000, wherein the polyamide-based thermoplastic elastomer comprises, as a hard segment, a polyamide synthesized using a monomer represented by the following Formula (1) or Formula (2):
- wherein, in Formula (1), R1 represents a hydrocarbon molecular chain having a carbon number of from 2 to 20 or an alkylene group having a carbon number of from 2 to 20, and, in Formula (2), R2 represents a hydrocarbon molecular chain having a carbon number of from 3 to 20 or an alkylene group having a carbon number of from 3 to 20, and wherein the polyamide comprises a structural unit represented by —CO—(CH2)11—NH—.
