FIELD: winter tires.
SUBSTANCE: at least one of the blocks is provided with one or more profiled three-dimensional slots in the radial direction. The profiled slit is limited by two mutually consistent profiled surfaces - the sides of the slit formed by the plate during vulcanization. Each side of the three-dimensional slit is in the form of a recurring V-shaped element with pads at the base, inserted in the direction of the radial plane, interrupted in the radial direction at a certain interval, and replaced by a Z-shaped surface formed from the same repetitive element, forming a 3D- slot-like slits, the angles of which with the radial plane are 75°.
EFFECT: improved tire performance in wet, dry and snowy conditions.
