Zusammenfassung:	PCT No. PCT/DE89/00501 Sec. 371 Date May 17, 1990 Sec. 102(e) Date May 17, 1990 PCT Filed Aug. 1, 1989 PCT Pub. No. WO90/03895 PCT Pub. Date Apr. 19, 1990.A circuit arrangement is suggested for monitoring the air volume in vehicle tires which effects the most accurate possible correction of the temperature measured by a sensor fastened at the wheel to the actual air temperature in the tire. For this purpose, the temperature and pressure measurement value of the tire measured by the rotating sensor (13) of the wheel to be monitored is fed to a correction circuit (18) which is also receives a plurality of correction parameters (p, F, K, v). A corrected value for the temperature (tk) or for the air pressure in the tire is transmitted at the output of the correction circuit (18) as a function of the correction parameters (FIG. 1).
