Problems solved by technology
[0002] At present, the production of pneumatic tires has evolved from the previous period of high carbon black fillers to high-performance silica, which has caused the tread rubber to be non-conductive, and a conductive chimney has been added to solve this problem. However, the current environment and government environmental protection and energy saving requirements are more stringent Strict, in order to achieve the goal of low rolling resistance, the manufacturer made the entire tire non-conductive, and this tire failed to pass the conductive test standard

Abstract
The invention discloses a pneumatic tire. The pneumatic tire comprises a crown area, an outer tread is arranged on the outer circle of the crown area in a surrounding mode, a tread joint used for releasing static electricity is arranged on the outer tread and internally provided with a tread rubber-removing electric connector, the tread rubber-removing electric connector is connected into a carcass material, and the carcass material is internally provided with a conductive rubber piece. According to the pneumatic tire, a new path is added under the situation that a carcass does not have the conductive capability, the conductive rubber piece is located inside, thus vehicle static electricity passes through a tire bead area, sequentially passes through ebonite to the conductive rubber piece,then reaches the crown area and is transmitted to the outer tread of the crown area. The resistance value of the pneumatic tire can be decreased. The invention further discloses a manufacturing method of the pneumatic tire.
Description
technical field [0001] The invention relates to the technical field of tires, in particular to a pneumatic tire and a manufacturing method thereof. Background technique [0002] At present, the production of pneumatic tires has evolved from the previous period of high carbon black fillers to high-performance silica, which has caused the tread rubber to be non-conductive, and a conductive chimney has been added to solve this problem. However, the environment and government environmental protection and energy saving requirements are more stringent Strict, in order to achieve the goal of low rolling resistance, the manufacturer made the entire tire non-conductive, and this tire failed to pass the conductive test standard. [0003] Therefore, how to provide a pneumatic tire to reduce the resistance value of the tire is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the purpose of the present invention...
