  • Patent number: 10377183
    Abstract: The tread includes over at least a first axial part (M) at least one wavy groove in a first direction and wavy grooves in a second direction. The wavy grooves in the second direction are connected to the wavy groove in the first direction. Over at least a second axial part (B) of the tread, at least one wavy groove continuous in a third direction, and wavy grooves continue in a fourth direction. The wavy grooves in the fourth direction are connected to the wavy groove in the third direction. When new, the open parts of the first axial part (M) are connected to one another, and the open parts of the second axial part (B) are not connected with one another. Beyond a part-wear condition, the open parts of the second axial part (B) are connected to one another, and the open parts of the first axial part (M) are not connected with one another.
