PURPOSE: A dip cord using the hybrid cord and a radial tire using the same are provided to solve adhesive strength problems and to improve a safety of tire. CONSTITUTION: The dip cord using the hybrid cord and the radial tire using the same has following processes. A pre twisted yarn is manufactured by applying a S direction to one layer of polyketone yarn. A post twisted yarn is manufactured by applying a Z direction of 300 - 500 TPM to one layer of polyketone pre twisted yarn and one layer of untwisted aramid yarn, respectively. The raw cord is manufactured by plaiting the post twisted yarn into two layers and applying a S direction of 300 - 500 TPM.
