Tread block arrangement having a sipe

A tread block arrangement suitable for a tire or for a tread band for a tire, the tread block arrangement comprising:

• a tread block that limits a first primary sipe, the first primary sipe comprising at least a first deep part and a second deep part separated from the first deep part by a first shallow part,
• wherein
• a depth of the first deep part is at least three times a depth of the first shallow part,
• a depth of the second deep part is at least three times the depth of the first shallow part,
• the tread block arrangement defines a primary boundary and a central line which is parallel to the primary boundary,
• a second shallow part of the first primary sipe is located closer to the primary boundary than the first shallow part,
• the second shallow part is located further away from the central line than the first shallow part,
• the first shallow part has a first primary length on a level of a bottom of the first shallow part, and
• the second shallow part has a second primary length on a level of a bottom of the second shallow part,
• wherein
• the second primary length is greater than the first primary length,
• the first deep part is limited in a longitudinal direction of the first primary sipe by a primary first end wall and a secondary first end wall such that a first angle between the primary first end wall and the secondary first end wall is from 1 degree to 30 degrees, and
• the second deep part is limited in a longitudinal direction of the first primary sipe by a primary second end wall and a secondary second end wall such that a second angle between the primary second end wall and the secondary second end wall is from 1 degree to 30 degrees.
