<p>The present invention provides a rubber composition for coating a steel cord, in which both rubber strength and rolling resistance property can be improved, and a tire using the rubber composition. A rubber composition for coating a steel cord, comprising 30 to 100 parts by mass of a reinforcing agent, 5 to 40 parts by mass of an organic vulcanizing agent on the basis of 100 parts by mass of a diene rubber, and an organic acid cobalt,
wherein the organic vulcanizing agent is represented by the following general formula:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-(R-S x ) n -
wherein R is (CH 2 -CH 2 -O) m -CH 2 -CH 2 , x is an integer of 3 to 6, n is an integer of 10 to 400, and m is an integer of 2 to 5, and a tire having a steel cord coated with the rubber composition.</p> |
