Abstract

The tread (2) has S-shaped transverse grooves (3). At the edges (4) of the plan view of the contact surface they run at an angle beta 1, subtending between 65 degrees and 90 degrees with the circumferential direction (U). Near the centre (5), this angle decreases to beta 2, between 30 degrees and 50 degrees . Here (5), a single rectangular block, its edges roughly perpendicular to the line of the S-shape, interrupts the centre of the S-feature (9). The short edges (8) of the block align with the groove edges of the leading and trailing S-features (3a, 3b).
