The invention relates to a pneumatic tire for a vehicle, in particular for use under winter driving conditions, comprising a profiled tread which has a running surface that defines a base level and which comprises profiled blocks (4, 5), each profiled block being divided into profiled block segments (4a, 5a) by means of at least two parallel cuts (6, 7) which run at an angle of ≤ 45° relative to the axial direction of the tread and which have outlet openings with a width (b1) of 0.40 mm to 0.80 mm and cut walls (6a, 7a). At least one profiled block segment (4a, 5a) has a rib structure made of at least one rib (8) which runs along and laterally to the outlet opening of a cut (6, 7) and over the extension thereof and which is made of a rib flank (8a) that runs in the radial direction as an extension of one cut wall (6a, 7a), a plateau (8b) with a width (b2) of 0.10 mm to 0.40 mm, and a concavely rounded rib flank (8c) that descends to the base level at the profiled block segment (4a, 5a), said rib having a height (δh) of 0.20 mm to 0.70 mm with respect to the base level.
