<p>The running surface of a vehicle tyre has at least two rows of profiled blocks (2, 3, 4, 5, 6) separated by a circumferential groove (8, 9, 10, 7). The sides (31, 32) of the grooves (8, 9, 10, 7) run radially outward from the bottom (30) of the grooves and are formed by the sides of the profiled blocks (2, 3, 4, 5, 6). The outer ends of the side walls are displaced axially (34, 37) at intervals round the circumference.</p> |
