Abstract:
A pneumatic vehicle tire with a tread comprising circumferential grooves (2) and at least one profile rib (1), which runs around in the circumferential direction and formed in which there are grooves (4) which at a groove flank (5) of a circumferential groove (2) that delimits the profile rib (1) open into it, wherein the groove flanks (5) of the circumferential groove (2) run at an angle (β) of 12° to 17° to the radial direction, thereby widening the circumferential groove (2) in the direction of the periphery of the tread.The grooves (4) run at an angle (α) of 45°±20° to the axial direction, end within the profile rib (1), have a maximum depth (t2) of 3.5 mm and open in each case into a local indentation (7), which is formed at the groove flank (5), reaches up to the periphery of the tread, is concavely rounded along the groove flank (5) and has a bottom (7a) that runs in particular parallel to the periphery of the tread and is at a distance (c), determined in the radial direction, of 0.5 mm to 2.0 mm from the deepest point of the groove (6) of the circumferential groove (2).
