Abstract: A mold extruder for a tire with a highly electrically conductive ring and a manufacturing method using the same. The extruder solves the problem of static electricity caused by failure to discharge charges generated in a vehicle body, to the ground, but accumulating charges on the tire when a large amount of silica is used into the tread rubber composition of a tire. The mold extruding die for forming a conductive ring on the tread extrudes a cap tread, an under tread, and tread wings simultaneously, is installed to a head section of a mold extruder having a tri-extruder for extruding a tire tread, and includes a preform die, a final die, and a cassette. The extruding passages for the cap tread, the under tread, and the tread wings are formed by assembling the preform die, the final die, and the cassette.

Abstract: The present invention relates to a tire having a tread structure with improved electrostatic discharge properties, and more particularly, to a tire containing large amounts of silica, which has a tread structure with improved electrostatic electricity discharge properties. The tire of the present invention has a band-shaped electric discharge passage 30, which is extended from the under tread 20 to the outer surface of the cap tread 10 while being exposed to the outside of the tire through the outer surface of the cap tread 10. Thus, the tire of present invention has excellent conductivity without decreasing physical properties of the tread structure.
