Rubber composition for coating tire cord

A rubber composition for coating a tire cord comprising 0.7 to 3 parts by weight of benzothiazolyl sulfenamide or benzothiazolyl sulfenimide represented by the chemical formula (1):

• wherein R1 is a linear alkyl group having a branched structure of 4 to 16 carbon atoms, and R2 is a linear alkyl group having a branched structure of 4 to 16 carbon atoms or a benzothiazolyl sulfide group based on 100 parts by weight of a rubber component containing at least 60% by weight of a natural rubber and/or an isoprene rubber,
• 45 to 70 parts by weight of carbon black based on 100 parts be weight of said rubber component or 4 to 20 parts by weight of silica based on 100 parts by weight of said rubber component and 3 to 7 parts by weight of sulfur based on 100 parts by weight of said rubber component, and
• 0.05 to 0.2 parts by weight of an organic cobalt converted to cobalt based on 100 parts by weight of said rubber component and
• wherein said rubber composition does not contain either resorcin resin or cresol resin.
