Document Type and Number:
Japanese Patent JP7287437
Kind Code:
B2
Abstract:
The present invention discloses a rubber composition that includes rubber, filler, a sulfur-containing silane coupling agent, and a vulcanization accelerator, the rubber including 30-60 parts by mass of NR and 40-70 parts by mass of BR, the filler including carbon black and silica, the CTAB specific surface area of the carbon black and the silica being 60-160 m2/g and 60-100 m2/g, respectively, the filler content being 55-75 parts by mass per 100 parts by mass of rubber, the amount of silica compounded with the filler (silica ratio) being 10 mass% or greater, and the amount of vulcanization accelerator compounded being 2.5-8 mass% relative to the silica.
