Abstract
The rubber composites for tire treads include silica; carbon black; and oil constituents, wherein a ratio (A index) of silica contents, carbon black contents, and oil constituents contents is represented by A index=silica contents/(carbon black contents+silica contents+oil constituents contents)≧0.8; and a ratio (B index) of a complex elastic modulus E* at 30° C. and a loss tangent tan δ at 60° C. is represented by B index=E*/tan δ≧120.
