Abstract:
A method of producing an antistatic tire comprising the steps of providing a tread having an electrically insulating central portion and a pair of outer electrically conducting shoulders; forming a plurality of spaced slits extending only partially into the tread inwardly from a rolling surface of the tread, the slits extending transversely across the central portion of the tread and into the shoulders; pouring a cement comprising a carbon black mix in a volatile liquid into the slits; evaporating the volatile liquid to leave said carbon black mix inside the slits to define, inside the tread, a continuous electrically conducting body; and connecting two electrically conducting sidewalls to the shoulders to form an antistatic tire having a continuous electrical path extending from the rolling surface of the tread to the sidewalls.
