A tire includes a body ply sheet having a rubber core defined by a top surface having a length and a width, a bottom surface having substantially the same length and width, and side surfaces having a common height. The body ply sheet includes reinforcement cords spaced 0.1-4.0 mm apart from each other and spanning the width of the body ply sheet. Bleeder cords are disposed on the body ply sheet and spaced are 8-12 cm apart from each other. Conductive cords are also disposed on the body ply and are spaced 20-80 cm apart from each other. At least one of the conductive cords has a first end and a second end, the first end being located in a region within a middle 80% of a width of the circumferential tread.

A tire includes a body ply sheet having a rubber core defined by a top surface having a length and a width, a bottom surface having substantially the same length and width, and side surfaces having a common height. The rubber core is further defined by a top rubber layer and a bottom rubber layer. The body ply sheet includes reinforcement cords disposed between the top rubber layer and the bottom rubber layer. The reinforcement cords are spaced 0.1-4.0 mm apart from each other and span the width of the body ply sheet. Bleeder cords are disposed on the body ply sheet and spaced 8-12 cm apart from each other. Conductive cords are also disposed on the body ply and spaced 20-80 cm apart from each other.

The present invention provides a pneumatic tire, which includes a belt layer laminated and formed on an upper side of a carcass ply inside a tread portion, and a plurality of air vent cords arranged between the carcass ply and the belt with a predetermined interval, wherein at least a part of the air vent cords is formed so as to have electrical conductivity, thus to electrically communicate the carcass ply and the belt layer with each other, such that a static electricity generated in a body of an automobile is discharged through the tread grounded to the road surface via the carcass ply which electrically contacts with a tire wheel, thereby preventing an accident that may occur due to the static electricity in the automobile.

In a pneumatic tire, respective end portions in the tire circumferential direction of a composite layer of an inner liner and a rubber layer are jointed at a joint portion; the lower inner liner layer has a first edge and the upper inner liner layer has a second edge at the joint portion; the first edge is separated from the upper inner liner layer by the rubber layer; provided that a position on the upper inner liner layer at the same height as the lower inner liner layer and closest to the first edge is P, a circumferential distance measured from the first edge to the position P is L, and a circumferential distance measured from the second edge to the position P is T, T35 mm, TL/29 mm, and 0T<L0.2T.
