摘要： A pneumatic tire has a tread rubber provided in an outer side of a carcass layer in a tread portion. the tread rubber has a cap portion which is formed by a non-conductive rubber and constructs a ground-contacting surface, a base portion which is provided in an inner side in the tire diametrical direction of the cap portion, and a conductive portion which is formed by a conductive rubber and extends in a thickness direction of the tread rubber so as to reach a bottom surface of the tread rubber from the ground-contacting surface. A thickness of the conductive portion is made relatively large in a center portion in the thickness direction of the tread rubber, and the thickness of the conductive portion is made relatively small in both end portions in the thickness direction of the tread rubber.

摘要： 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.
