A tyre tread has a central and two side regions, each covering a third of the width. Three straight, wide circumferential grooves encircle the central region, defining two central bands. In the side regions there are cross grooves, conferring a block structure. In this original pattern, curved incisions with blind ends run from the bordering grooves (1) into terminations within the bands (3). Cross grooves (6) in two sections (6a, 6b) in the side regions have a V-shaped course and intersect with further grooves (7) running from the circumferential region. |
