A vehicle tire having first areas of a higher degree of rigidity and second areas of a lower degree of rigidity, the first and second areas having different degrees of radially inward recession upon contact of the tire with the ground and being alternately arranged in the circumferential direction of the tire. Each of the second areas comprises a central projection and a plurality of projections surrounding the central projection in spaced relation and spaced from each other. Some of the projections which are located at the tread edges have side surfaces extending substantially parallel to a radial plane through the tire. The outermost projections disposed adjacent to the projections at the tread edges have side surfaces facing the ground and extending substantially perpendicularly relative to the side surfaces of the projections at the tread edges. With this arrangement, the tire can be driven with an increased degree of driving force on rough ground or terrain, such as sand and/or gravel.
