The electrical resistance value of the electrically conductive rubber and a portion of the tread portion is 1×106 Ω·cm or less. The electrical resistance value of the tire component, a coating rubber of the belt layer, and a coating rubber of the belt reinforcing layer is from 1×106 Ω·cm to 1×108 Ω·cm. The electrical resistance value of the rim cushion rubber and a side rubber of the sidewall portions is 1×108 Ω·cm or greater.
