Abstract: The present invention relates to a tire cord and a radial pneumatic tire, and is characterized in that when one raw nylon 6,6 or nylon 6 yarn and one aramid yarn are pre-twisted respectively and are then cabled to generate a raw cord, and when the raw cord is untwisted, the aramid yarn is input 5 to 100 mm/m longer than the nylon 6,6 or nylon 6 yarn. The hybrid dip cord according to the present invention has an excellent fatigue resistance of 80% or more, the initial deformation in the tensile test causes low modulus to be generated by nylon and causes high modulus to be expressed from the section where aramid begins to receive the force. As such, deformation is easy during the work of inflating the green tire inside the mold with the bladder, which makes the manufacturing of tires easy.
