FIELD: tire production.

SUBSTANCE: invention predominantly relates to a winter tire. The tire contains tread bracelet (2), on which there is a set of first transverse grooves (30) and a set of second transverse grooves (60), which are inconsistently inclined relatively to first transverse grooves (30). Each first transverse groove (30) contains first section (33) having an inclination relatively to the specified direction along the circumference at the first angle (A), and second section (34), which is a continuation of first section (33), having an inclination relatively to the specified direction along the circumference at the second angle (B), which is less than the first angle (A). Each second transverse groove (60) contains first section (62) having an inclination relatively to the direction along the circumference at the third angle (C), second section (63) passing from first section (62) and having an inclination relatively to the direction along the circumference at the fourth angle (D), which is less than or equal to the third angle (C), and ending in specified second section (34) of specified first transverse grooves (30), as well as third section (64) passing from second section (34) and parallel to the latter.
