<p>A pneumatic tyre, especially for winter driving, has a tread profile with a central broad circumferential channel(1) separating central block rows(6,7) in each tread half and other circumferential(3,4) and axially(2) aligned channels forming a further row of blocks and a shoulder block row. All blocks have fine lamellae cuts and the lateral channels form an arrow profile in both tread halves in the direction of rotation. The circumferential channels(3,4) comprise channel parts(3a,4a) at an angle( alpha ) of 5-25 degrees , preferably 10-20 degrees to the circumference(A-A) and running in opposite directions in each tread half. The channel parts(4a) between the blocks(6a,7a) of the central block rows(6,7) are narrower than the channel parts(3a) between the shoulder block rows(5) and the adjacent central block rows(6,7), have constant breadth and are shallower than the maximum tread depth.</p> |
