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 DEG to 25 DEG . |
