<P>PROBLEM TO BE SOLVED: To provide a rubber composition for a tire that improves low-fuel consumption properties, abrasion resistance, and wet skid performance with a good balance, and a pneumatic tire. <P>SOLUTION: The rubber composition for a tire includes a copolymer with a weight-average molecular weight of 1.0×10<SP POS="POST">5</SP>-2.5×10<SP POS="POST">6</SP>and a compound represented by formula, R<SP POS="POST">101</SP>-S-S-A-S-S-R<SP POS="POST">102</SP>. The copolymer is obtained by copolymerizing 1,3-butadiene, styrene, and a compound represented by formula (I), wherein R<SP POS="POST">1</SP>represents a 1-10C hydrocarbon group, and has an amino group at one end and a functional group including at least one element selected from the group consisting of nitrogen, oxygen, and silicon at the other end. <P>COPYRIGHT: (C)2013,JPO&INPIT |
