A pneumatic tire, the tread of which is provided with zigzagged grooves. In order to keep rocks or similar solid foreign objects from getting stuck in the tread recesses, and in order to have these rocks drop out of the tread when the associated tire axis pivots, the side faces or the zigzagged grooves are stepped. Furthermore, the step faces, which extend approximately transverse to the circumferential direction of the tire, are disposed at an incline to a plane which extends through the main axis of the tire. Side faces which merge into one another via a given step face are parallel to one another, yet are staggered relative to one another by the width of this step face. The step faces are upwardly inclined at approximately 15° to 25°.

1. A tread configuration, for a pneumatic vehicle tire, comprising zigzagged circumferential grooves, each of which has a base and two opposite sides; each side is stepped in such a way as to form side faces, which essentially extend in the circumferential direction of said tire, and step faces, which essentially extend transverse to the circumferential direction of said tire; said side faces of a given side of one of said circumferential grooves are grouped into pairs, with said side faces of each of said pairs merging into one another via a given one of said step faces; said step faces are disposed at an angle to a radial plane defined as extending through the main axis of said tire, such that the step faces slope upwardly toward the tread surface, each two side faces of a given pair of side faces, which merge into one another; being staggered by the width of said one step face, with the width of the latter being that dimension thereof which extends substantially transverse to the circumferential direction of said tire. 2. A tread configuration according to claim 1, in which, in a given one of said circumferential grooves, step faces which face one another in said opposite sides of said groove are disposed at oppositely inclined angles relative to said radial plane. 3. A tread configuration according to claim 1, in which said step faces are disposed at an angle of approximately 15° to 25° relative to said radial plane. 4. A tread configuration according to claim 3, in which said step faces are disposed at an angle of 20°. 5. A tread configuration according to claim 1, in which, on a given side of one of said circumferential grooves, two adjacent side faces of two adjacent pairs of side faces extend at different angles relative to the circumferential direction of said tire and merge with one another along an edge which essentially extends in the radial direction of said tire; when viewed in the transverse direction, said edges are aligned with one another in such a way that on one side of a given groove a projection is formed which extends into said groove, and on the opposite side of said groove a recess is formed which essentially conforms to said projection; the step face of a given projection, and the step face of a given oppositely located recess, are disposed at oppositely inclined angles relative to said radial plane.
