Pneumatic Tire
摘要:
A pneumatic tire that can maintain processability and tire performance such as rolling resistance or a wet performance of a tire, overcome the problem of non-conductivity by a tread rubber of silica formulation or the like, and sustain conductive performance of a tire over a long period of time is provided. The pneumatic tire includes a non-conductive tread and a side wall, a rubber member comprising a conductive rubber, penetrating a tread rubber from the outer surface of a cap tread being provided to form a continuous conducting path to a rim via a cap ply, a belt, a carcass and a rim strip, wherein the rubber member includes a rubber composition comprising 100 parts by weight of a rubber component containing from 50 to 100 parts by weight of a diene rubber having a weight average molecular weight (Mw) of from 250,000 to 450,000, and from 10 to 30 parts by weight of carbon black having a nitrogen adsorption specific surface area (N2SA) of from 700 to 1,300 m2/g and a dibutyl phthalate (DBP) absorption of from 300 to 550 cm3/100 g.
