An object of the present invention is to provide a rubber composition which is excellent in cord adhesiveness, steering stability and elongation at break. The present invention relates to a rubber composition for coating a steel cord comprising not less than 0.12 part by mass of zinc benzoate and/or zinc t-butylbenzoate, 0.03 to 0.30 part by mass of fatty acid cobalt salt in terms of cobalt element, and less than 0.5 part by mass in total of a fatty acid having 16 to 22 carbon atoms and a fatty acid derived from the fatty acid cobalt salt which has 16 to 22 carbon atoms based on 100 parts by mass of a rubber component, and a tire having a breaker and/or a carcass obtained by use of the rubber composition for coating a steel cord.
