The invention relates to a utility vehicle tyre having a tread with at least one circumferential channel (2, 2′, 2″) with a channel base (5) and channel walls (4, 4′), wherein base elevations (7, 7′, 7″) are formed on the channel base (5) in a manner distributed over the circumference and acting centrally as stone ejectors, with a height (h1, h3) of 25% to 60% of the profile height (T1) and a greater extent in the circumferential direction than in the axial direction, which base elevations (7, 7′, 7″) either contact the channel walls (4, 4′) or are at distances (a1) of up to 4.0 mm therefrom in the axial direction and are bounded in the radial direction by a top surface (8, 8′, 8″) having an encircling surface edge, wherein the channel walls (4, 4′) between the base elevations (7, 7′, 7″) have wall portions (4a, 4′a) which converge toward each other.The top surface (8, 8′, 8″) of the base elevations (7, 7′, 7″) slopes downward uniformly toward the surface edge, wherein the channel walls (4, 4′) have, to the side of the base elevations (7, 7′, 7″), wall sections (4b, 4′b) which are convexly curved toward one another in a plan view, and wherein the surface edge of the top surface (8, 8′, 8″) follows the profile of the wall sections (4b, 4′b) which are convexly curved toward one another, such that the width of the base elevations (7, 7′, 7″) decreases toward those ends thereof which lie in the circumferential direction.
