<p><P>PROBLEM TO BE SOLVED: To provide a rubber composition for a tire in which kneading processability, a low heat buildup property, flexural fatigue resistance, air permeability resistance, and driving stability are obtained by a good balance, and to provide a pneumatic tire using the same. <P>SOLUTION: The rubber composition for a tire includes: an epoxidized natural rubber having 15-65 mole% of an epoxidation degree; and an epoxidized butadiene rubber having 15-65 mole% of an epoxidation degree, wherein the total content of the epoxidized natural rubber and the epoxidized butadiene rubber is at least 65 mass% in 100 mass% of a rubber component, and includes 20-100 pts.mass of silica based on 100 pts.mass of a rubber component. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
