<P>PROBLEM TO BE SOLVED: To provide a rubber composition for tire tread improving low-temperature motion performance such as on-snow performance or on-ice performance by further improving adhesive frictional force on ice and snow road surfaces. <P>SOLUTION: The rubber composition for tire tread includes, to 100 pts.mass of diene-based rubber, 1-50 pts.mass of polymer gel that is a crosslinked diene-based polymer particle having a glass transition point of -90 to -30°C, and 0.1-10 pts.mass of a lignin derivative (lignin sulphonate). A pneumatic tire provided with tread using the rubber composition is also provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
