Claim 0:
1. A utility vehicle tire comprising:
a tread having a circumferential channel formed to a profile depth that is between a central profile positive and a shoulder-side profile positive;
channel flanks from the circumferential channel toward the central profile positive;
shoulder flanks from the shoulder-side profile positive running toward a side wall;
the channel flanks provided with a plurality of channel depressions that extend into the central profile positive and are open toward a surface of the tread and have a depth in an axial direction of 2.0 mm to 5.0 mm and a width in a circumferential direction of 4.0 mm to 15.0 mm as measured at a level of the channel flank;
the shoulder flanks provided with a plurality of shoulder depressions that extend into the central profile positive and are open toward a surface of the tread and have a depth in the axial direction of 2.0 mm to 5.0 mm and a width in the circumferential direction of 4.0 mm to 15.0 mm as measured at a level of the shoulder flank;
the channel depressions delimited by a curved channel surface that goes over without a kink into the channel flank at a channel depth of 35% to 90% of the profile depth;
the shoulder depressions delimited by a curved shoulder surface that goes over without a kink into the shoulder flank at a shoulder depth of 35% to 150% of the profile depth; and
the channel depressions each comprising:
side edges that are angled relative to the circumferential direction to form sides of a trapezoid when the channel depression is viewed in plan view;
a profile positive edge oriented in the circumferential direction that forms an upper base of the trapezoid when viewed in plan view; and
a bottom formed by the curved channel surface which runs arcuately and outwardly convexly with a continuous and constant curvature from the profile positive edge to a radially inner end where the channel depression converges with the shoulder flank and forms a lower base of the trapezoid when viewed in plan view;
wherein the side edges run at an angle (β) of 30° to 80° in relation to the circumferential direction.
