Static electricity of a vehicle is discharged to the road surface without aggravating uniformity. A tread rubber (2G) includes a base portion (9) arranged on the radial inside to extend continuously from one tread end (e1) side to the other tread end (e2) side and made of nonconductive rubber, a cap portion (10) made of nonconductive rubber and arranged on the radial outside of the base portion (9) to constitute the tread (2a), and a conductive portion (11) made of conductive rubber and having one end exposed to the tread (2a) and the other end connected to a sidewall rubber (3G) electricallyconductive with the rim when the rim is assembled. The cap portion (10) includes a first cap portion (10A) and a second cap portion (10B) which are obtained by vertical division. The conductive portion (11) extends from the tread (2a) toward the radial inside between the first cap portion (10A) and the second cap portion (10B), and extends in the axial direction between the base portion (9) and one of the first cap portion (10A) or the second cap portion (10B) before being connected to the sidewall rubber (3G).
