Abstract (en)

[origin: WO0218159A1] The invention concerns a method for enhancing dry ground adherence of a tyre casing comprising a running tread (1) based on an electrically insulating material which is delimited laterally by two side surfaces (4 and 5) linking between them inner and outer radial surfaces (2 and 3) of said running thread. The invention is characterised in that the method consists in using a running tread comprising on its circumference at least a conductive ply (10) substantially linking said side surfaces (4 and 5) to each other, said ply (10) having lower resistivity than that of said insulating material, which is radially provided on both sides (11 and 12) of said ply (10) in said running tread (1).
