Abstract

A tread configuration for pneumatic vehicle tires, especially for spare tires. A number of recesses are arranged in succession and next to each other in the circumferential direction of the tire. Transverse ribs and substantially circumferential ribs separate the recesses from one another and have a width which is approximately 1/4 to 3/4 of the circumferential dimension of the recesses. The radially outwardly located peripheral surface of the tire is subdivided into several segments. Within each of the segments, the circumferential dimension of the recesses and of the transverse ribs is constant, and the circumferential dimension of the recesses and of the transverse ribs is different in successive segments. The recesses are of such a cross-sectional shape or outline that at least one boundary line thereof is formed by an edge of a transverse rib. At least some of the circumferential ribs extend at an angle to the circumferential direction of the tire.
