RUBBER COMPOSITION FOR TIRE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition for tire having improved low rolling resistance, wet grip performance and processability.SOLUTION: A reinforcement filler containing carbon black and silica of 50 to 200 pts.wt. are blended based on 100 pts.wt. of a rubber component containing 50 to 100 wt.% of masticated rubber master batch where 0.3 to 5.0 wt.% of a specific compound represented by the general formula (i) coexists with 100 wt.% of a diene rubber containing natural rubber and/or isoprene rubber of 40 wt.% or more with the percentage of the carbon black of 30 wt.% or more in the reinforcement filler, and a silane coupling agent having a mercapto group is blended at 1 to 20 wt.% of the silica weight.SELECTED DRAWING: None
