Tire with electrically non-conductive tread which contains electrically conductive rubber strip

A tire having a tread of a cap/base construction comprised of:

• (A) a electrically resistive rubber tread cap layer having an outer running surface,
• (B) an electrically conductive rubber tread base layer underlying said tread cap layer, and
• (C) a thin, relatively electrically conductive (relative to said tread cap rubber layer), rubber strip as a part of the tread base rubber layer which extends radially outward from said tread base layer through said tread cap layer to and including said outer running surface of said tread cap layer,
• wherein said thin rubber strip extension is unitary with and of the same rubber composition as said tread base rubber layer and is thereby a unitary extension of said tread base rubber layer;
• characterized in that composite of electrically conductive rubber strip and tread cap rubber layer at the running surface of the tread has a substantially uniform abradability.
