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.

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.

Abstract: A vehicle wheel having a rigid wheel rim upon which a pneumatic belted tire is mounted. The beads of the tire contain pull-resistant cores, and are secured by a wheel flange against sliding laterally from the seating surfaces. A recess for receiving a tire bead during mounting of the tire is located adjacent to the seating surface on that side facing the rim middle. The seating surfaces are arranged on the inner periphery of the rim adjacent to a radially inwardly extending wheel flange. The base of the recess has a larger diameter than do the seating surfaces. The mantle surfaces of the rim adjacent to the recess are essentially even or smooth supporting surfaces for the tire zenith or crown portion during emergency operation of the tire. The middle portion of the rim, between the mantle surfaces, is also embodied at least partially as a supporting surface for the tire zenith portion during emergency operation of the tire, and the supporting surface lies essentially at the level of the mantle surfaces.

Abstract: A tread configuration for pneumatic vehicle tires, particularly for spare tires, having a large number of depressions which are separated from each other by transverse webs and peripheral webs, and are successively arranged in the transverse and the peripheral directions of the tire. The depressions have an approximately rectangular cross section, and extend transverse to the peripheral direction of the tire. The webs which limit or define the depressions have a width corresponding to approximately 1/4 to 3/4 of the peripheral dimension of the depressions.
