Zusammenfassung:The invention relates to a pneumatic tyre for a vehicle, comprising a tyre tread with profiled positives, for example profiled blocks or profiled strips, separated from each other by grooves, in which at least one spike (2) is respectively positioned in a spike hole (1), recesses (4, 4', 6) ending inside the profiled positives at least on sides of the spikes (2) opposing each other in the peripheral direction (U) being designed to receive the ice particles created as the spike scratches (2) on the ice. On the opposing sides of the spikes (2) in the peripheral direction (U), an individual recess (4, 4', 6) is embodied with a peripheral edge zone (4a, 4'a, 6a) in a top view and a core zone (4b, 4'b, 6b) located inside the edge zone (4a, 4'a, 6a) in a top view, the core zone (4b, 4'b,6b) being deeper than the edge zone (4a, 4'a, 6a) in the radial direction in relation to the tyre tread periphery, and the depth (tb, tb') of the core zone (4b, 4'b, 6b) increases continuously in the peripheral direction (U) towards the spike (2).
