<P>PROBLEM TO BE SOLVED: To provide a rubber composition for a tire capable of improving low fuel consumption and mechanical strength after heat deterioration, and to provide a pneumatic tire in which the rubber composition for a tire is used for tire members (particularly, sidewall packing). <P>SOLUTION: The rubber composition for a tire includes a natural rubber, a compound represented by formula (1) and/or formula (2), a carbon black, and a compound represented by formula (A). In formula (1), p represents an integer of 2-8. In formula (2), q represents an integer of 2-8, M<SP POS="POST">r+</SP>represents a metal ion, and r represents the valence of M. In formula (A), Y represents a 2-10C alkylene group, and R<SP POS="POST">10</SP>and R<SP POS="POST">11</SP>are the same or different and represent a nitrogen atom-containing monovalent organic group. <P>COPYRIGHT: (C)2013,JPO&INPIT |
