Abstract

PURPOSE: To prevent the damage and puncture of a tube for a pneumatic tire by employing rubber composition containing micro organic short fiber for a barrier rubber, thereby preventing the exposure of cords.
CONSTITUTION: Cord barrier rubber is a composition obtained by mixing 100pts. wt. of rubber of at least one type selected from the group consisting of natural rubber, synthetic polyisoprene rubber and butyl rubber, 10W100pts.wt. of carbon black and 3W30pts.wt of micro organic short fiber. The micro organic short fiber has glass transition temperature in the amorphous part lower than 30°C or higher than 120°C, 0.8W30μm of mean short fiber length, 0.1W0.8μm of mean short fiber diameter, 8W400 of a ratio of the length to the diameter of the average short fibers, a melting point of the crystal part higher than 160°C and a glass transition temperature out of the tire heating temperature range. The innermost side first ply 4 of a carcass 1 is lined with a cord barrier rubber thin layer 5 containing the micro organic short fiber.
