Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2016/035709
Kind Code:
A1
Abstract:
In order to compatibly achieve both rolling resistance efficiency and high-speed durability, and electrical resistance reduction efficiency, a pneumatic tire is provided with a belt layer (7), a belt reinforcement layer (8), a tread part (2), a sidewall part (4), a rim cushion rubber (5A), and a conductive rubber (11) which is disposed together with the rim cushion rubber and has one end thereof exposed to contact a rim on the outer surface of the rim cushion rubber, and the other end thereof contacting a tire constituent member adjacent to the rim cushion rubber. In terms of electrical resistance, the conductive rubber and a portion of the tread part have a value of 1×106 Ω or less; the tire constituent member, a coating rubber of the belt layer, and a coating rubber of the belt reinforcement layer have a value of 1×106-1×108 Ω inclusive; and the rim cushion rubber and a side rubber 4A of the sidewall part have a value of 1×108 Ω or more.
