ABSTRACT:
In an apparatus for testing a motor vehicle tire and in particular for ascertaining characteristic parameters of a bead thereof, the bead of the tire is subjected to stretching by radially outwardly displaceable clamping jaws and the compression force applied to the tire by the respective clamping jaws are measured by force measuring means. Each of the force measuring means includes a respective measuring body in which a force transmission portion carries the actuating force applied to the respective clamping jaw and experiences deformation in consequence of the force. The force transmission portion bears strain gauges to measure the force, and it is supported by resiliently bendable support portions in such as way that the measuring body is substantially insensitive to moments and transverse forces which could result from radial guidance for the clamping jaws.
