PROBLEM TO BE SOLVED: To provide a rubber composition having a frictional force on ice and wear resistance superior to those by a conventional technique, and to provide a pneumatic tire using the composition. SOLUTION: The rubber composition is obtained by compounding 20-70 pts.mass of at least one kind of fillers selected from the group consisting of carbon black and a white filler, and 1-30 pts.mass of a polyethylene oxide having≥100,000 of a viscosity-averaged molecular weight Mv, with 100 pts.mass of a diene rubber. The pneumatic tire uses the rubber composition for a tread (3). COPYRIGHT: (C)2012,JPO&INPIT |
