Abstract: A method and apparatus for vulcanizing pneumatic vehicle tires having heads that in the mounted state are disposed on the radially inner periphery of a rim. In order for such tires to achieve a satisfactorily contoured vulcanization, and in order at the same time to produce sealing surfaces with great precision, the tire is vulcanized with its beads in their operating position. During the vulcanization, the radially outwardly disposed surfaces of the tire beads are shaped with the aid of rigid, one-piece, shaped molding rings.

Abstract: An apparatus for vulcanizing pneumatic vehicle tires where the tire beads, in the mounted state, are disposed on the radially inner periphery of a rim next to the essentially radially inwardly extending rim flanges. In order to obtain tires having a long service life and tire beads with a good sealing quality, it is proposed that the tire be vulcanized in essentially the proper contour for operation. Two, respectively radially segmented, bead-forming rings that have a variable diameter and can be displaced axially are provided. For the purpose of vulcanizing the sealing surfaces disposed in the interior of the tire so that these surfaces will rest on the rim in an airtight manner, the bead-forming rings are introduced, in a radially retracted state, into the interior of the tire blank, whereby at least one of the tire beads is ovally deformed.

Abstract: A method of producing a pneumatic vehicle tire, the beads of which can be mounted on the radially inner periphery of a rim, and are pivotably relative to the bead cores. A carcass along with the adjacent rubber layers, and the tire beads, with their pull and compression resistant cores, are combined on a drum to form an essentially cylindrical blank. What will later be the insides of the tire initially face radially outwardly, and the interfaces of the initially radially outwardly extending beads form an essentially right angle with the cylindrical surface of the blank. At least the bead regions of the tire blank are preliminarily vulcanized, whereupon the blank is turned in and has imparted thereto a toroidal shape. The blank is then provided with a tread strip, and is final-vulcanized.

Abstract: A pneumatic vehicle tire made of rubber or rubber-like material and having a reinforcing carcass that is anchored in the beads by being looped around bead cores that are essentially inextensible and/or resistant to compression. The bead cores have an essentially round overall cross-sectional shape. To increase the bending resistance of the bead cores, each bead core has an inner region of steel or other material of similar high strength and rigidity. Each inner region has a cross-sectional shape that is characterized by a dimension, in the radial direction of the bead core, that is greater than its dimension in the axial direction. Each bead core also has an outer region, of lightweight material, that complements the inner region to provide the essentially round overall cross-sectional shape for the bead core.

Abstract: A vehicle wheel having a rigid rim on which can be mounted a pneumatic rubber tire. The tire beads are adapted to be disposed on the radially inner side of the rim ring. Deep mounting beds are located axially inwardly of the rim seating surfaces for the tire bead. In order to prevent the penetration of water and dirt into the deep mounting beads, the tire beads each have a cross-sectional shape which on the one hand during mounting allow the tire bead to enter the mounting space having the deep bed, and on the other hand in the operating position of the tire close off the mounting space having the deep bed region.

Abstract: A method and apparatus for demounting a pneumatic vehicle tire, the beads of which, in the mounted state, are disposed on the radially inner periphery of a wheel rim having a deep mounting bed and, laterally outwardly therefrom, rim flanges which extend essentially radially inwardly. First, a portion of a given tire bead is forced into the deep mounting bed, and subsequently the oppositely located portion of the same tire bead is lifted over the rim flange.
