ABSTRACT:
A pneumatic tire is provided with an electrically conductive path extending continuously from a position in the rim contacting surface to a position in the ground contacting surface through a sidewall portion, wherein a sidewall rubber is a high-performance rubber compound and almost-insulative, having a volume resistivity of not less than 1×10^8 ohm cm. The electrically conductive path includes a helical path made of an electrically conductive rubber having a volume resistivity of not more than 1×10^7 ohm cm. The helical path is disposed axially inside the sidewall rubber and extends spirally around the tire rotational axis. Preferably, the tread rubber, clinch rubber and carcass topping rubber are also almost-insulative high-performance rubber compounds.
