Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2013/058092
Kind Code:
A1
Abstract:
Provided is a pneumatic tire that, having appropriately secured electrification performance, has improved absorption or damping, increasing ride comfort. The pneumatic tire has: a nonconductive carcass (4); a side rubber section (Sg) configured from a rim strip rubber (7) and a side wall rubber (6) formed from a nonconductive rubber; and a conductive pathway (Ph) that electrically connects the ground-contact surface of a tread section (3) and the rim-contacting position of a bead section (1). The side rubber section (Sg) is provided with a radial conductive section (8) that extends in the tire radial direction (RD), and the radial conductive section (8) is formed from a conductive rubber and configures a portion of the conductive pathway (Ph). Furthermore, a conductive branch section (9) is provided that passes within the side rubber section (Sg) extending to the inside in the thickness direction of the side rubber section (Sg) having branched from the radial conductive section (8). The conductive branch section (9) is disposed at a position that partitions the side rubber section (Sg) into an outside and inside in the tire radial direction (RD), and is formed from a conductive rubber having a hardness that differs from the rubber hardness of the side rubber section (Sg).
