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.
