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.
Claims5
A pneumatic tire comprising:
- a carcass which reaches a bead portion from a tread portion via a side wall portion;
- a tread rubber which is formed by a nonconductive rubber and constructs an outer surface of the tread portion in an outer side of the carcass;
- a side wall rubber which is formed by a nonconductive rubber and constructs an outer surface of the side wall portion in the outer side of the carcass;
- and
- a rim strip rubber which constructs an outer surface of the bead portion in the outer side of the carcass,
- wherein the pneumatic tire has a conductive sheet which is formed by a conductive rubber, reaches the rim strip rubber from the tread rubber while passing between the carcass and the side wall rubber, and terminates without being exposed to an outer surface of the bead portion, and
- wherein 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.
