Abstract

A tread configuration for pneumatic vehicle tires, especially for spare tires. A number of rectangular depressions are arranged in succession and next to each other in the circumferential direction of the tire. Transverse ribs and circumferential ribs separate the depressions from one another and have a width which is approximately 1/4 to 3/4 of the circumferential dimension of the depressions. The radially outwardly located peripheral surface of the tire is subdivided into several segments. The circumferential dimension of the depressions and of the transverse ribs is constant within each of the segments, and the circumferential dimension of the depressions and of the transverse ribs is different in successive segments.
