<p>PROBLEM TO BE SOLVED: To provide a rubber composition for tires which allows improvement of wet grip performance without deterioration of other capabilities, e.g. rolling resistance, and a tire using the rubber composition in a tread member.SOLUTION: A rubber composition for tires comprises 100 pts. mass of rubber ingredients containing at least one selected from natural rubber, polyisoprene rubber and polybutadiene rubber and 0.5-50 pts. mass of a hydrogenated resin, and the hydrogenated resin is a hydrogenated terpene resin obtained by hydrogenating terpene resin and has a softening point of 80-180°C. In the rubber ingredients, the combined content of natural rubber, polyisoprene rubber and polybutadiene rubber is 50 mass% or more. A tire using the rubber composition in a tread member is also provided.</p> |
