<P>PROBLEM TO BE SOLVED: To provide a rubber composition for tires capable of improving wet grip performance, heat sag properties and abrasion resistance in good balance; and a pneumatic tire using the rubber composition. <P>SOLUTION: The rubber composition for tires includes a compound represented by formula (I); a thiuram compound (R<SP POS="POST">4</SP>-CS-Sx<SP POS="POST">3</SP>-CS-R<SP POS="POST">5</SP>); and an inorganic compound (kM<SB POS="POST">1</SB>xSiO<SB POS="POST">y</SB>zH<SB POS="POST">2</SB>O). In the formula (I), A is a 1-15C hydrocarbon group; R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>are the same or different mutually and are each an alkyl-substituted amino group, aralkyl-substituted amino group or a cyclic amino group; n is an integer of 1-12; x<SP POS="POST">1</SP>and x<SP POS="POST">2</SP>are the same or different mutually and are each an integer of 1-12; R<SP POS="POST">4</SP>and R<SP POS="POST">5</SP>are each an amino group derivative; x<SP POS="POST">3</SP>is an integer of 1-4; M<SB POS="POST">1</SB>is one of Al, Mg, Ti, and Ca or its oxide or hydroxide; k is an integer of 1-5; x and z are integers of 0-10; and y is an integer of 2-5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
