| description | A rubber composition is disclosed comprising, based on parts by weight per 100 parts by weight rubber (phr),
(A) conjugated diene-based elastomers comprising:
(1) from 20 to 70 phr of a solution polymerization prepared styrene/butadiene elastomer (S-SBR-A) having a styrene content in a range of from 35 to 45 percent and a Tg in a range of from -30°C to -50°C,
(2) from 20 to 60 phr of a solution polymerization prepared styrene/butadiene elastomer (S-SBR-B) having a styrene content in a range of from 35 to 45 percent and a Tg in a range of from -3°C to -23°C, and
(3) from 5 to 30 phr of an aqueous emulsion polymerization prepared styrene/butadiene elastomer (E-SBR) having a styrene content in a range of from 35 to 45 percent and a Tg in a range of from -30°C to -50°C;
wherein said Tg's of said S-SBR-A, S-SBR-B and E-SBR are spaced apart from each other by at least 4°C; and
(B) from 8 to 30 phr of at least three, preferably from three to five, different resins selected from the group polyester phthalate resin, styrene/alphamethyl styrene resin, gum rosin, coumarone indene resin and alkylphenol acetylene resin. The rubber composition may be used in a tread of a pneumatic tire. |
