Tire and a lamella plate for the manufacture of a sipe of a tire

A tire comprising:

• a tread provided with a first tread block separated from another tread block by a portion of a groove, wherein:
• the first tread block comprises:
• a first primary first wall;
• and
• a second primary first wall such that a primary first sipe is arranged between the first primary first wall and the second primary first wall;
• wherein:
• the first primary first wall is provided with a first primary first wall indentation and first primary first wall protrusion,
• the second primary first wall is provided with a second primary first wall indentation and a second primary first wall protrusion,
• the first primary first wall defines a first primary first wall surface having a planar surface or a curved surface, from which the first primary first wall protrusion protrudes and into which the first primary first wall indentation descends,
• the second primary first wall defines a second primary first wall surface having a planar surface or a curved surface, from which the second primary first wall protrusion protrudes and into which the second primary first wall indentation descends,
• the first primary first wall indentation is geometrically congruent with the second primary first wall protrusion,
• the first primary first wall protrusion is geometrically congruent with the second primary first wall indentation,
• the first primary first wall protrusion is asymmetric about all planes that have a normal that is parallel to a wall projection line, which is a projection of a line that remains in between a center of the first primary first wall protrusion and a center of the first primary first wall indentation, the projection being a normal projection to the first primary first wall surface,
• a first part of a surface of the first primary wall protrusion is inclined so that a height of the first primary wall protrusion, as measured from the first primary first wall surface, decreases from a maximal height towards the first primary first wall indentation by a first inclination,
• a second part of the surface of the first primary wall protrusion is inclined so that a height of the first primary wall protrusion, as measured from the first primary wall surface, decreases from the maximal height away from the first primary first wall indentation by a second inclination,
• the second inclination is different from the first inclination, and
• the second inclination defines an inclination angle of less than 85 degrees.
