Abstract
The present invention provides a rubber composition for tire tread having compatibility between low fuel consumption and abrasion resistance, especially abrasion resistance under severe condition. The rubber composition for tire tread is obtained by adding carbon black containing silica as 10 to 55 parts by weight based on a rubber component of 100 parts by weight and silica coupling agent of 2 to 8% by weight based on the carbon black containing silica.
