Abstract:
An antistatic tire comprising a tread, two sidewalls, and two annular shoulders, each shoulder interposed between the tread and a respective said sidewall; the tread and the sidewalls being formed respectively from a first and second mix; and the tread defining part of a rolling surface, at least an annular portion of which is electrically conducting and has an electrical resistivity of less than 109 ohmsÃ—cm; characterized in that said electrically conducting portion of the rolling surface is defined by at least a portion of an electrically conducting element, that is formed from a third electrically conducting mix, which under low strain and in the cured state, has substantially the same stiffness as said first mix in the cured state, and, under high strain, has substantially the same stiffness as said second mix in the cured state.
