More Information
Summary:The present technology provides a rubber composition for a tire which improves the low rolling resistance, dry performance, wet performance, and workability so as to surpass conventional levels. In the rubber composition for a tire according to the present technology, silica is blended into the composition in an amount of 90 to 150 parts by mass relative to 100 parts by mass of a diene rubber containing at least 25 mass % of a modified conjugated diene polymer rubber having a siloxane structure in at least some of the terminal-modifying groups. A silane coupling agent is blended into the composition in an amount of 3 to 20 mass % relative to the amount of silica, and an alkyltriethoxysilane having an alkyl group with 7 to 20 carbons is blended in an amount of 0.1 to 20 mass % relative to the amount of silica.
