Abstract:
A heavy-Load bearing tire having a tread, the tread being made of a rubber mix and comprising at least one incision, said at least one incision being defined by opposing walls, each wall being defined geometrically by an average surface having hollowed and/or protruding elements in relief, the elements in relief of one wall being intended to cooperate with the elements in relief of the opposing wall when the tread contacts a roadway, wherein the tread defines a running surface and the width of the at least one incision is variable and is at a maximum in that region of the tread which undergoes maximum Poisson effect deformation resulting when said tread bears a load during contact with the roadway, to obtain, over the entire surface of the walls defining said at least one incision, cooperation of all the elements in relief of said walls.
