A tire with a belt exhibiting high durability by enhancing the fatigue resistance of a cord especially at the end of a circumferential belt layer, especially a heavy loading radial tire with a small aspect ratio. The tire has a belt where at least one circumferential belt layer formed by coating with rubber a large number of cords extending along the equatorial plane of the tire, and at least twoinclining belt layers formed by coating with rubber a large number of cords extending while inclining with respect to the equatorial plane O of the tire are arranged sequentially on the radial outsideof the crown of a carcass as a frame stretching toroidally between a pair of beads, and has treads arranged on the radial outside of the belt. The circumferential belt layer has a width equal to or larger than 60% of the total width of the tire, at least one inclining belt layer has a width larger than that of the circumferential belt layer, and the modulus of elasticity of a cord arranged on theend side in the width direction is set smaller than that of a cord arranged on the inside in the width direction of the cord in the circumferential belt layer.
