<p>This invention relates to a rubber composition and to a tire with tread of rubber composition prepared with filler reinforcement, a majority of which is silica reinforcement, together with a silica coupling agent, and a minority is carbon black and conventional rubber compounding ingredients wherein at least one of said compounding ingredients and/or coupling agent is liquid and is provided as being deposited on a specified carbon black carrier. In particular, the carbon black carrier is characterized by having a DBP value in a range of 280 to 600 cm<3>/100g and a BET value in a range of 550 to 1200 m<2>/g. The selection of the said carbon black carrier is intended to reduce the electrical volume resistivity of the tread composition.</p> |
