Abstract
The present invention relates to a pneumonic tire and a rubber composition used in the same, both of which are capable of preventing static charge build-up on a tire surface without degrading various tire performances such as rolling resistance and so on, and particularly to a rubber composition comprising 10 to 30 parts by mass of an ionic liquid and 5 to 95 parts by mass of silica per 100 parts by mass of a rubber component containing at least 50% by mass of styrene-butadiene rubber, as well as a pneumatic tire using such a rubber composition in a tread portion.
