    Abstract: A tire including reinforcement layers 6a and 6b including a reinforcing material and a vulcanized rubber covering the reinforcing material, where the vulcanized rubber is a vulcanized rubber of a rubber composition containing N-cyclohexyl-2-benzothiazolylsulfenamide, the reinforcing material contains a metal where a steel cord surface is covered with a ternary plating of copper, zinc and iron, the reinforcement layers 6a and 6b are arranged on the inside of a tread surface in the tire radial direction, and a ratio (a/b) of a modulus (a) at 50 % elongation of the vulcanized rubber covering the reinforcing material in the central portion 6C and a modulus (b) at 50 % elongation of the vulcanized rubber covering the reinforcing material in the end portion 6E of the reinforcement layers 6a and 6b in the tire width direction is 0.94 to 1.06. The tire has a high modulus and excellent productivity.
