PNEUMATIC TYRES FOR A VEHICLE

Vehicle air tire, in particular for use under winter driving conditions, with a tread having at least one profile block row (1, 2, 3), whose profile blocks (1a, 2a, 3a) are separated from one another in the circumferential direction by transverse grooves (4, 5, 6), wherein profile blocks (2a, 3a) are provided with at least two cuts (10) that extend at least substantially parallel to one another and to the profile block edges delimited by the transverse grooves (4, 5). [0002] Profile blocks (2a, 3a) are provided with cuts (10) which, each proceeding from a center line (m) running in the direction of extension of the cut (10), alternately have a section (10b, 10c) pointing in one circumferential direction and one pointing in the other circumferential direction, running along the sides and one base line of a substantially isosceles trapezoid, wherein the center line (m) forms the second, longer base line of the trapezoids.
