RUBBER COMPOSITION FOR TREAD, AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a tread rubber composition for improving wet grip performance, and to provide a pneumatic tire with a tread manufactured by using the same.

SOLUTION: The tread rubber composition can be obtained by mixing: a master batch 1 including a rubber component A containing a natural rubber and a terpene-based resin and/or a rosin-based resin; and a master batch 2 including a rubber component B containing a diene-based synthetic rubber, and α-methyl styrene-based resin and a terpene phenol-based resin.
