ABSTRACT:
A rubber composition of tire tread, which comprises an emulsion-polymerized styrene-butadiene rubber with a bonded styrene content of not less than 40% by weight which is contained in an amount of 10 to 100% by weight in a rubber component, and a sodium-containing basic inorganic compound and/or a basic sodium salt of organic acid which is blended in an amount of 0.5 to 5.0 parts by weight per 100 parts by weight of the rubber component. Safe driving at a high speed can be realized by using the rubber compositions.
