摘要： This invention relates to a tire having a circumferential electrically non-conductive (relatively electrically non-conductive) rubber tread which contains an electrically conductive (relatively electrically conductive) rubber strip extending from an electrically conductive underlying tread base rubber layer (underlying the tread) through the rubber tread to its running surface. The rubber strip contains a dispersion of carbon nanotubes to provide its electrical conductivity and to thereby provide a path of least electrical resistance through the tread to its running surface.

摘要： The present disclosure relates to a pneumatic tire having at least one electrically conductive pathway capable of dissipating electrostatic charges generated in a vehicle to a road surface while achieving low rolling resistance and improved wet traction tire performances. The pneumatic tire has a tread portion which includes a tread cap layer forming a ground contacting surface and a tread base layer underlying the tread cap layer. The tread cap layer contains at least one electrically conductive pathway locally extending from the ground-contacting surface of the tread cap layer to contact the tread base layer. The electrically-conductive pathway is composed of a UV-cured rubber composition which is electrically conductive.

摘要： In A pneumatic tire, a conductive portion is arranged between peripheral grooves in the outermost side in a tire width direction and is arranged in a land portion including a whole void ratio maximum difference position. The whole void ratio maximum difference position is a position where a difference of a void ratio between one side and the other side in the tire width direction becomes maximum in a void ratio of the outer surface between ground ends of a tread rubber in the tire width direction.
