A vehicle wheel having an annular emergency support arranged within the hollow space of a pneumatic tire mounted on the wheel. The annular support is supported on the rim of the wheel between the two beads of the tire and next to the drop center of the rim by means of a projection located on the inner periphery of the annular support. The projection extends radially inwardly and may be introduced into the drop center to facilitate mounting and removal of the annular support.

Vehicle wheel with annular emergency support

A pneumatic tire for a vehicle wheel, according to which in the hollow chamber of the pneumatic tire there is arranged a hollow emergency ring or an emergency tube with one or more peripheral protrusions having running-up flanks which when moving into the respective flattened effective surface are substantially located in the elongation of an imaginary secant determined by the respective flattened effective surface.

Pneumatic tire for a vehicle wheel

A vehicle wheel equipped with an annular solid rubber tire having its marginal portions provided with beads resting in and held by lateral wheel flanges. The rubber tire extends around an annular channel into which the tire can partially deflect. The wheel flanges are spreadable away from each other by spring tension.

Vehicle wheel with rubber tire

A belt for a belted tire with an inner continuous layer and with an outer layer divided into two marginal sections and an intermediate section. The strength carriers of the inner belt layer extend over the width thereof in one direction and at a first angle with regard to the circumferential direction of the belt. The strength carriers of the intermediate section of the outer layer extend only over the width of the intermediate section and at the same angle as the first mentioned angle but in an opposite direction to the strength members of the inner belt layer. The strength members of the marginal sections extending in the same direction as the strength members of the intermediate section but at a smaller angle with regard the circumferential direction of the belt than the angle at which the strength members of the outer belt layer extend. The marginal areas of the inner belt layer as well as the marginal sections of the outer belt layer folded over the adjacent areas of the intermediate belt section of the outer belt layer. Prior to applying the belt to the carcass of a raw tire, the diameter of the belt is extended by from 5 to 25%.

Belt for belted tires and method of making same

A bead core for pneumatic tires which is composed of wires, cables, cords or similar thread-shaped strength carriers wound to form a plurality of windings. These windings are formed by successive coils or spiral sections of a continuous strength carrier. The bead core furthermore includes one or more additional windings respectively formed by rings closed in themselves.

Bead core for pneumatic tires

A bead core for pneumatic tires which is composed of a plurality of annular or coil shaped sections of wires, cables or cords. These sections which are of substantially the same size and dimensions interlock each other by each section passing at least once through another section.
