Title:
タイヤ用ゴム組成物およびそれを用いたタイヤ
Document Type and Number:
Japanese Patent JP7095716
Kind Code:
B2
Abstract:
To provide a rubber composition for tires capable of simultaneously improving heat build-up properties, breaking strength, and wear resistance while increasing a vulcanization rate.SOLUTION: The rubber composition for tires is obtained by blending 100 pts.mass of a diene rubber containing 65-100 pts.mass of a styrene-butadiene copolymer rubber and 0-35 pts.mass of a butadiene rubber with: 50-200 pts.mass of silica having a CTAB specific surface area of 200-300 m2/g; and 0.5-20 pts.mass of a phenolic resin having at least one ethyleneamine-derived structural unit represented by -(NH-C2H4)- in the molecule.SELECTED DRAWING: None
