RUBBER COMPOSITION FOR TIRE

PROBLEM TO BE SOLVED: To provide a rubber composition which is suppressed in the reduction of hardness, and further is improved in processability, while maintaining wet performance and low rolling resistance. SOLUTION: The rubber composition for the tire contains 100 pts.wt. of diene based rubber co...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rubber composition which is suppressed in the reduction of hardness, and further is improved in processability, while maintaining wet performance and low rolling resistance. SOLUTION: The rubber composition for the tire contains 100 pts.wt. of diene based rubber containing 30-70 pts.wt., 60-80 pts.wt. of silica, and 0.5-2.5 pts.wt. of polysiloxane having a repetition unit represented by formula (I): (wherein R1independently represents a methyl group, an ethyl group or a phenyl group, R2independently represents hydrogen or an organic group, R3independently represents an alkyl group or an acyl group, m is an integer of 0 or 1 or more, and n is an integer of 1 or more) and having a number average molecular weight of 200-100,000.
