RUBBER COMPOSITION FOR TIRE AND PNEUMATIC TIRE USING SAME

WIPO Patent Application WO/2018/110410

A1

The purpose of the present invention is to provide: a rubber composition for a tire that can improve workability while maintaining a reinforcement property which is a characteristic of hydrogenated copolymers; and a pneumatic tire using the rubber composition. The present invention is a rubber composition for a tire and is characterized by containing 3–30 parts by mass of a crosslinked rubber particles with respect to 100 parts by mass of a hydrogenated copolymer, the hydrogenated copolymer being obtained by hydrogenating an aromatic vinyl–conjugated diene copolymer and configured such that a weight-average molecular weight measured using gel permeation chromatography is at least 300,000, and such that the hydrogenation rate of the conjugated diene part is at least 80 mol%.
