Abstract
A pneumatic tire capable of reducing rolling resistance and discharging static electricity generated during running, wherein each of a tread rubber, a breaker rubber, and a sidewall rubber formed on the tread part, the breaker part, and the sidewall part, respectively, has a volume specific resistivity of 1×10Ω·cm or more, the pneumatic tire further including a conduction rubber embedded in the tread part so as to be at least partially exposed to a surface of the tread part, bead part rubber disposed at a region contacting a rim flange of the bead part, and electroconductive rubber electrically connecting the conduction rubber to the beat part rubber, wherein each of the conduction rubber, the bead part rubber, and the electroconductive rubber has a volume specific resistivity of less than 10Ω·cm.
