Pneumatic tire and green tire manufacturing method

A pneumatic tire comprising at least two circumferential main grooves and at least two land portions defined and formed by the at least two circumferential main grooves, the at least two land portions comprising a center land portion positioned on a tire equator and a bulging land portion bulging toward an outer side in a tire radial direction with respect to a reference arc, the bulging land portion being offset from the tire equator, the pneumatic tire further comprising a tread portion formed of non-electrically-conductive rubber and electrically conductive rubber, integrally molded and vulcanized together to form the tread portion,

• wherein when the pneumatic tire is mounted on a regular rim, inflated to a regular internal pressure, and in an unloaded state, in a tire meridian cross-sectional view, the electrically conductive rubber being formed in a region corresponding to the bulging land portion except for a region with a width of 5% of a width of the bulging land portion and being centered at a bulging apex position bulging most toward an outer side of the bulging land portion in the tire radial direction, the region in which the electrically conductive rubber is formed being offset from a center of the bulging land portion in a tire width direction,
• wherein LE≥(0.05×Lr/2)+(GD/TrGa)×(Ho/Lr)×La is satisfied, where variables are, in a tire meridian cross-sectional view, a dimension LE along a tire profile from the bulging apex position to a center position of the electrically conductive rubber in the tire width direction, an overall dimension Lr of the bulging land portion along the tire profile, a depth GD of the circumferential main groove close to the bulging apex position, a tread gauge TrGa at the bulging apex position, a bulging amount Ho from the reference arc at the bulging apex position, and a dimension La of the bulging land portion along a profile line on a side having a larger dimension in the tire width direction, the side being demarcated by the bulging apex position, and
• wherein the reference arc being an arc passing through at least three of four opening ends of two circumferential main grooves adjacent to the bulging land portion in the tire width direction and comprising a center located further on an inner side than the opening ends in the tire radial direction and having a maximum radius of curvature, or
• the reference arc being an arc passing through two opening ends and a ground contact edge of a circumferential main groove adjacent to the bulging land portion on the inner side in the tire width direction and comprising a center located further on the inner side than the opening ends in the tire radial direction and having a maximum radius of curvature.
