    摘要： The invention relates to a rubber tire composed of carbon black reinforced rubber carcass and having a rubber tread which is quantitatively reinforced with silica and which, in turn, has a thin, integral, rubber outer cap on its outer surface which contains a quantitative amount of carbon black.
    In one aspect, said outer cap, sometimes referred to herein as an outer top cap, extends across the outer surface of the tread which is normally intended to be ground contacting and in an alternative aspect, the outer top cap extends only over the outer portion, namely the peripheral edges, of said tread surface intended to be ground contacting.
    The outer, carbon black reinforced, rubber tread top cap connects with at least one other carbon black reinforced rubber component of the tire in a manner to provide a path of reduced electrical resistance from said outer tread top cap to the bead portion of the tire carcass and, therefore, such a path from the vehicle to the road surface.
