PNEUMATIC TIRE AND METHOD FOR MANUFACTURING SAME

摘要

The collapse of conductive terminal rubber strips is prevented while a conductive terminal portion is formed stably to have an exposure width of 5mm or less. The conductive terminal portion is formed by continuously winding the terminal strips formed of a conductive rubber toward an outward radial direction from a tread conductive layer to a tread grounding surface. The terminal strip is sequentially wound while shifting a position at a pitch D of a distance in a tire axial direction while the terminal strip goes around such that the conductive terminal portion constitutes a trapezoidal cross section in which a width (Wa) of an upper base is smaller than a width (Ws) of the terminal strip and a width (Wb) of a lower base is larger than the width (Ws) of the terminal strip. The width (Wa) of the upper base is within a range of between 2mm and 5mm.
