摘要

PROBLEM TO BE SOLVED: To obtain both a pneumatic tire having improved processability and moldability, improved lightness and safety by using high-rigidity rubber and a rubber composition capable of producing the tire. SOLUTION: This rubber composition is obtained by using a master batch comprising 100 pts.wt. of a natural rubber latex and 20-50 pts.wt. of aramid short fiber.
