A tire comprising a silica reinforced rubber tread having a carbon black reinforced rubber sheath

摘要

The present invention relates to a carbon black reinforced carbon carcass consisting of a carbon black reinforced rubber carcass and comprising carbon reinforced carbon fibers reinforced quantitatively with an electrically non-conductive filler pigment such as silica and again at least partially, preferably substantially constant, To rubber tires having rubber treads surrounded by rubber.;In one embodiment, the rubber layer is typically in contact with the ground and extends across at least a portion of the outer surface of the tread that surrounds both ends of the tire tread, and optionally also the inner surface, to become a tread cap of a tread having a cap / base structure have.;The rubber layer is connected to one or more other carbon black reinforced rubber components of the tire in such a way as to provide a reduced electrical resistance path from the layer on the outer surface of the tread to the bead portion of the tire carcass, do.;In one embodiment, the tread structure may be a double extrusion of a rubber layer comprised of (i) the tread rubber and (ii) the associated rubber layer extensions on the outer surface of the tread wing and tread.
