PNEUMATIC TIRE
Abstract:
A pneumatic tire has a nonconductive tread rubber constructing an outer surface of a tread portion, a nonconductive side wall rubber constructing an outer surface of a side wall portion, and a rim strip rubber constructing an outer surface of a bead portion. The pneumatic tire has a conductive sheet formed by a conductive rubber. The conductive sheet reaches the rim strip rubber from the tread rubber while passing between a carcass and the side wall rubber, and terminates without being exposed to the outer surface of the bead portion. The rim strip rubber is partitioned into a nonconductive rubber portion and a conductive rubber portion, and the conductive rubber portion is connected to the conductive sheet and is exposed to a bead bottom surface.
