All sides of individual blocks (2, 3, 4), adjacent to the peripheral drains (6, 7), contain with the peripheral axis (1) of the tyre same angle (alpha), the directional orientation is in each of the halves of the coat surface of the tyre opposite to the peripheral axis (1) mutually opposite and the widths of both peripheral arm drains (7) are same and equal to 1.2 to 1.5 multiple of the widths of the same peripheral inner drains (6), whilst the parts of the common surface, adjacent to the side (8) and arranged along the vertical drain (5) on the side oriented in the rotation direction of the tyre, each arm block (4) has a recess (13) with width (w1) equal to 0.3 to 0.5 multiple of width (w2) of the arm block (4) and length (L1) equal to 0.5 to 0.7 multiple of the length (L2) of the arm block (4).
