Abstract

A system for indirectly monitoring the inflation pressure of pneumatic-tyred vehicle wheels, and also to a wheel. The wheel is having a wheel body with a rim part and a disc part, and a tyre detachably fitted on the rim part of the wheel body. The wheel comprises at least one deformation sensor for sensing the tyre inflation pressure at the time, and the system comprises a data transmission device for transmitting sensor signals of the at least one sensor to an evaluation device, and an evaluation device for evaluating the sensor signals. In order to provide a system and vehicle wheels that are simplified in comparison with the tyre pressure monitoring system previously used, the deformation sensor is fitted on the wheel body and is usable or used for sensing inflation-pressure-dependent deformations of the wheel body.
