The invention relates to a tread block arrangement (160) of a tread band (150) or a tire (160). The tread block arrangement forms a tread (170) that is meant for a rolling contact against a ground surface (900), wherein the tread (170) is provided with at least one longitudinal groove (180, 182). The tread block arrangement (160) limits a first number (NT) of sipes, of which a second number (NTT) are transversal sipes (200, 210, Si, Sj), of which a third number (N) of sipes (Si, Sj) form a group (G1). For each sipe (Si) of the group (G1), the tread block arrangement (160) forms a bottom (221), a first sidewall (222), a second sidewall (224), and a first end wall (228, 228). The end first end wall (228) of each sipe (Si) of the group (G1) is configured such that a distance (d) between the first end wall (228) of the sipe (Si) in question and an outer side (172, 174) of the pneumatic tire (100) or the tread band (150) is less than a distance (d) between the other end (227) of the sipe (Si) in question and the outer side (172, 174). Moreover, at least a part of the first end wall (228) of the sipe (Si) in question has a first surface normal (N1si) of the sipe (Si) in question, and the first surface normal (N1si) of the sipe in question (Si) forms a first angle (β) of the sipe in question (Si) of at least 20 degrees with the tread (170). Furthermore, the ratio (NTT/NT) of the second number (NTT) to the first number (N) is at least 75 % and the ratio (N/NTT) of the third number (N) to the second number (NTT) is at least 20 %.
