The invention relates to a method for producing a tread (20), comprising the steps: extruding the tread (20), which has an outer side (22) and an inner side (24), opposite the outer side (22), and a carrying region (26) made of a carrying region rubber material and a guide strip (28) made of a guide strip rubber material, wherein the guide strip (28) extends from the outside (22) to the inside (24) and a specific electrical guide strip resistance (W.sub.28) of the guide strip rubber material is smaller than a specific electrical carrying region resistance of the carrying region rubber material. The steps according to the invention are: determining an electrical guide strip resistance (W.sub.28) of the guide strip (28) between the outer side (22) and the inner side (24) and outputting a warning signal when the electrical resistance (W) exceeds a specified maximum resistance (W.sub.28,max).

A system for powering an electronic device within a tire is provided, the system comprising: a generator electrically connected to an electrically conductive wheel, the tire being mounted upon the wheel; the tire including bead portions, sidewalls, shoulders, a tread oriented in a trend region, an inner surface, and a metallic cord oriented within an interior of the tire; at least one conductive element extending from a bead portion and piercing into the interior of the tire and electrically connecting to the metallic cord; at least one electronic device within the vehicle tire; and at least one ground path extending through a thickness of the vehicle tire from the inner surface to an exterior surface in a contact patch of the tread; and wherein the at least one electronic device is electrically connected to the metallic cord and the at least one ground path.

A method for manufacturing a tire includes a rubber layer forming step of helically wrapping non-conductive strip rubber supplied from an extruder around an outer circumferential side of a conductive case main body to form a plurality of rubber layers. The rubber layer forming step includes: a non-conductive strip rubber wrapping step of wrapping the non-conductive strip rubber around; and a conductive strip rubber wrapping step of superposing conductive rubber on the non-conductive strip rubber to wrap around as conductive strip rubber. The conductive strip rubber wrapping step includes: wrapping pieces of the conductive rubber around in a layered manner so as to overlap each other in a tire radial direction; and forming a conductive portion reaching up to a tire surface.

Aspects of the invention relate to a tire that includes a shoulder wedge arranged in a shoulder portion of the tire between the sidewall and the belt package, the shoulder wedge being at least partially inserted between the belt package and the carcass ply. The tread includes a tread chimney component extending from the shoulder wedge to the rolling surface. The overlay coat of the tire's belt package, the tread band except for the tread chimney component, the tread base and the tire sidewall are made from non-conductive rubber. A conductive path between the rolling surface and the rim is provided across the tread chimney component, the shoulder wedge, the carcass ply and the chafer portion.

A tire includes a circumferential tread disposed in a crown region of the tire and an undertread disposed below the circumferential tread. The tire also has a pair of bead regions, including a first bead region and a second bead region, and a body ply extending from the first bead region to the second bead region. The tire further has a pair of sidewalls, including a first sidewall extending between the first bead region and the circumferential tread and a second sidewall extending between the second bead region and the circumferential tread. The tire also has a sidewall antenna adjacent to the first sidewall. The sidewall antenna has a first end contacting the undertread and a second end contacting the body ply.

A tire includes a pair of beads and a crown region including a circumferential tread disposed radially above a circumferential belt. The tire further includes a pair sidewalls extending from the pair of beads to the crown region. A body ply wraps around the pair of beads and terminates in a pair of turn up ends in the crown region, below the middle 30% of the circumferential belt. A conductive substance is disposed along a strip of the body ply.

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.
