<p><P>PROBLEM TO BE SOLVED: To provide a rubber composition for tires, the thermal degradation resistance of which is enhanced and particularly the performance such as the hardness of which is restrained from being changed (particularly, hardening degradation of rubber) owing to the long hour use thereof without increasing the amount of an antioxidant, the vulcanized one of which is excellent in rolling resistance properties and wear resistance, which can be vulcanized in a shortened time while keeping excellent scorch resistance and the cross-linkage efficiency of which can be enhanced and to provide a pneumatic tire each member of which is obtained by using the rubber composition for tires. <P>SOLUTION: The rubber composition for tires contains a rubber component containing≥25 mass% at least one kind of rubber selected from the group consisting of isoprene rubber and butadiene rubber, a specific benzothiazole compound, and a thiuram-based vulcanization accelerator of 0.1-1.3 parts mass based on 100 parts mass rubber component. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
