The side of each tooth of the longitudinal axis of vertical drains (5) between individual middle blocks (5) and longitudinal axis of vertical drains (5) in the marginal sectors (e, c, f) between individual inner and arm blocks (3, 4) contain with the peripheral axis (1) an angle (beta), which is more than 70 and less than 80 , and the other side of the tooth contains with the peripheral axis (1) an angle (alpha), which is more than 162 and less than 168 , whilst the line (14) put forward the peaks of these teeth at any side of any block (2, 3, 4) contains with the peripheral axis (1) of the tyre an angle (gamma), which is more than 10 and less than 16 , whilst the angle contained between the peripheral axis (1) of the tyre and longitudinal axes of the vertical drains (5) in the parts between the sectors (f) and sides (8) of the tyre and in the parts between the sectors (e) and (c) is more than 90 . The vertical cuts (9) in the blocks (2, 3, 4) come out of the joins of adjacent sides of two next to each other arranged teeth and are parallel with the longitudinal axes of vertical drains (5) in spatially consistent peripheral parts of the tyre coat. Mutually opposite vertical cuts (9) of the inner blocks (3) can be interconnected, whilst these interconnections are parallel with the longitudinal axes of the vertical drains (5) in spatially consistent peripheral parts of the tyre coat.
