TIRE PREVENTING STATIC ELECTRICITY

摘要

PURPOSE: A tire is provided to form many inserting holes in a tread and to discharge static electricity to the ground by filling a conductive rubber into the inserting holes. CONSTITUTION: A tire forms many inserting holes in a tread penetrated into a cap tread(1) to reach the upper part of an under tread(2) and fills conductive rubber(5) into the inserting holes. The lower part of the inserting holes is molded in a hanging sill shape so as to prevent the conductive rubber from separating. The interval of the inserting holes is 3 to 15cm and the number of inserting holes is 15 to 300 and the inserting holes are distributed over the both sides, the center part of whole part of the tread.
