Abstract:
Provided is a pneumatic tire including a pair of bead portions; at least one carcass layer extending between the pair of bead portions; a belt layer disposed outward of the carcass layer in a tire radial direction; a tread rubber disposed outward of the belt layer in the tire radial direction; a pair of sidewall rubbers disposed outward of the carcass layer in a tire lateral direction; and an electrically conductive portion extending between the pair of bead portions and having at least one separation portion, the electrically conductive portion having a linear structure, the linear structure including an electrically conductive linear member formed in a linear shape by molding an electrically conductive material with an electrical resistivity of less than 1×10{circumflex over ( )}8 Ω/cm.
