OPTImess sensors provide the possibility of non contact detection of tyre deformations under various test conditions, as, for example, wheel pressure, track, and inclination. This can be measurements at a roller type test stand but also - due to the small size of the sensors - measurements at the test vehicle.
A special preparation of the tyre, e.g. erasing of the marking, is not necessary. An extreme mode of application for this is the deformation-measurement of the contact surface of the tyre inside of a truck tyre. In this case, a specific OPTImess-sensor has been installed inside the tyre at the wheel rim and measures in direction of the tyre's surface.
