A TYRE COMPRISING A TREAD COMPOSED OF TWO RADIAL LAYERS

Application 360/MAS/1998 published 2006-10-20, filed 1998-02-23
A tyre comprising a tread composed of two radial layers, the reinforcing charge of which is predominantly silica, the radially upper layer (8) being made conductive by means of at least one annular insert (11) perpendicular to the surface of said tread, a crown reinforcement (9) and a carcass reinforcement (1) made conductive by means of a mix or mixes for encasing cables which are conductive, said reinforcements being separated from each other by a section (6) made up of a rubber mix slightly charged with carbon black or based on silica, and a connection conducting electrical charges connecting the surface of the tread to the mounting rim, the connection between two conductive layers or layers made conductive (8, 9, 1) separated by a non-conductive layer (7, 6) being constituted by at least one band (12, 13) of rubber mix of low thickness, width and length, placed between the two faces of the splice of the non-conductive layer and in contact with the means making conductive the two layers connected by the connection.
