Abstract: A pneumatic vehicle tire where the sheathing of the bead core ring is made of an elastomeric mixture that adheres well to steel and that contains plasticizer in the form of aromatic oils comprising approximately 2-10 parts silicon oil per one hundred parts elastomer.

Abstract: A pneumatic vehicle tire for use on a one-piece wheel rim having radially inwardly disposed rim shoulders on which corresponding bead portions of the tire are mounted. The tire bead portions have bead rings that are formed of flat strips, whereby the longest dimension of the cross-sectional configuration of the flat strips is parallel to the direction of a run-flat force, thereby fixing the greatest angular impulse force parallel to the run-flat force. This reliably prevents the tire bead from being thrown from the rim, especially during emergency operation.

Abstract: A method for detecting, evaluating, and indicating a tire air pressure value. Information signals are compared with a plurality of desired value curves having a tolerance range and an average value for the atmospheric temperature, whereupon these signals are evaluated. The pressure deviation, as a function of the desired value tolerance ranges, is assigned a specific pressure state, from which an acutal air pressure state is indicated that takes into account regional and seasonal pressure and temperature influences. Furthermore, a maximum speed and a permissible speed can be determined during emergency operation, or a state of emergency operation can be determined.
