ABSTRACT:
A tire whose crown is extended on both sides by a sidewall terminating in a bead and is provided with a tread formed in the major part of adjacent blocks separated from each other in the axial direction of the tire by circumferential or oblique grooves is characterized by the fact that at least some of the circumferential or oblique grooves separating the adjacent blocks in the axial direction have a cross section which decreases substantially from the leading edge to the trailing edge of the blocks.
