Abstract (en)
[origin: WO9858810A1] The present invention provides a tire (T) comprising a tread portion having a tread design pattern including circumferentially continuous ribs: lateral ribs (1) and other ribs (2). The tread portion is reinforced by a carcass having at least a ply (5), and by a belt having at least two working plies (61, 62). The working plies (61, 62) extend transversely beneath all the ribs, and extend beyond a limit line (7). The thickness (Ti) of the tread between the radially innermost part of the carcass ply (5) and the radially external surface (10) does not depart from the thickness (Tc) at the middle point by more than 10 %. The tire tread portion is molded so that the radially external surface of the lateral and other ribs defines a transverse profile that is substantially flat.
