TIRE TREAD RUBBER COMPOSITION AND PNEUMATIC TIRE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a tire tread rubber composition and a pneumatic tire using the same, that is excellent in frictional force on ice compared to the prior art.SOLUTION: The problem is solved by a tire tread rubber composition and a pneumatic tire using the same, that is obtained by blending 30 to 100 pts.mass of at least one filler selected from the group consisting of carbon black and white filler, and 0.1 to 20 pts.mass of carbonized cotton having an average fiber diameter of 20 μm or less and an average fiber length of 50 μm to 1000 μm, into 100 pts.mass of diene-based rubber.
