摘要： A non-pneumatic tire is provided that has a hub with a central axis. A supporting structure is located outward from the hub in a radial direction, and a shear band is located outward from the supporting structure in the radial direction. Tread is located outward from the shear band in the radial direction. A static discharge element extends from a first radial end of the supporting structure to a second radial end of the supporting structure. The first radial end is located closer to the central axis than the second radial end in the radial direction. The static discharge element is electrically conductive to conduct electricity through the supporting structure.

摘要： A pneumatic tire has a rubber member constructed by a rubber ribbon winding body formed by spirally winding a rubber ribbon. The rubber ribbon includes a composite rubber ribbon which is formed by a non-conductive rubber, and a conductive rubber partly covering the non-conductive rubber. The composite rubber ribbon has a flat cross sectional shape and is gradually reduced in its thickness toward both ends. The conductive rubber has a cross sectional area which is equal to or less than 3% of a cross sectional area of the composite rubber ribbon, and forms a surface in one side and a surface in the other side in both ends of the composite rubber ribbon. The composite rubber ribbons that are adjacent in the width direction are partly overlapped, and a conductive route is provided by the conductive rubber connected between the composite rubber ribbons.

摘要： The invention relates to a vehicle tire comprising a tread portion and a package of reinforcement layers arranged underneath the tread portion. The tread portion comprises a tread base layer arranged underneath the tread layer, and at least one rubber member that extends in the radial direction of the tire from the ground contacting surface to the reinforcement package. The tread layer rubber composition has an electrical resistivity at room temperature of more than 108 ohm-cm, the tread base layer rubber composition of between 106 ohm-cm and 108 ohm-cm, the member rubber composition of less than 106 ohm-cm; and the rubber composition of at least one layer of the reinforcement package has a electrical resistivity at room temperature of less than 106 ohm-cm. The vehicle tire combines a low rolling resistance with improved conductivity to avoid build-up of static electricity.
