Abstract
The present invention provides a rubber composition for coating a textile cord, and a tire using the rubber composition, wherein rolling resistance is lowered, and processability and rubber strength are excellent, as compared with a rubber composition for coating a textile cord comprising raw materials derived from petroleum resources as a main component, and a tire using the rubber composition, while considering environments and providing for the future decrease in petroleum resources supply. The rubber composition for coating a textile cord comprises 25 to 80 parts by mass of silica and 1 to 15 parts by mass of a silane coupling agent on the basis of 100 parts by mass of a diene rubber, wherein a nitrogen adsorbing-specific surface area of said silica is 70 to 150 m/g.
