<P>PROBLEM TO BE SOLVED: To provide a tread rubber composition capable of being improved well balancedly in grip performance, low-fuel consumption and wear resistance; and to provide a pneumatic tire using the same. <P>SOLUTION: The tread rubber composition contains a wet master batch obtained by mixing a rubber latex, a filler dispersion liquid and a liquid dienoic polymer emulsion. In the wet master batch, the filler dispersion liquid is one in which a filler is dispersed in an aqueous medium, and the liquid dienoic polymer emulsion is an oil-in-water type emulsion obtained by emulsifying a liquid dienoic polymer using a surfactant. <P>COPYRIGHT: (C)2012,JPO&INPIT |
