A tread rubber composition having improved abrasion resistance is provided. The tread rubber composition comprises a conjugated diene polymer or copolymer, at least one filler, from 2 to 10 phr of liquid polybutadiene, from 2 to 5 phr of zinc oxide and from 1 to 100 phr of process oil. The liquid polybutadiene is functionalized by reaction with unsaturated acid anhydride, has a number average molecular weight of from 3 to 8 kg/mol and an acid number of from 40 to 80. Also provided are methods for preparing the tread rubber composition comprising mixing of the foregoing ingredients by master-batch and final batch steps whereby the abrasion resistance of the tread rubber composition is improved.
