PROBLEM TO BE SOLVED: To enhance durability of a tire and workability during tire-making by improving a bead filler rubber composition, and to provide a pneumatic tire in which operation stability of the tire is compatible with ride quality. SOLUTION: This rubber composition is produced by compounding 100 pts.wt. of raw rubber, 1-6 pts.wt. of aromatic polyamide fibers, 0.2-2 pts.wt. of maleic acid modified liquid polybutadiene and carbon blend composed of 30-70 pts.wt. of hard carbon and 10-50 pts.wt. of soft carbon. The pneumatic tire has a pair of beads where the bead fillers composed of the rubber are arranged. |
