<p>The self-cleaning capability of a tyre (100) adapted for agricultural and/or tractor use is greatly improved by creating a discontinuity between circumferentially adjacent tread surface portions (102a, 102b) located between circumferentially consecutive lugs (101). The created discontinuity (103) extends between the lugs, without joining to the lugs themselves. The discontinuity extends in transverse direction, for example in direction substantially parallel to the direction followed by the lugs. Such discontinuity can be created by joining, at the adjacency thereof, tread surface portions located at different radial heights.</p> |
