An arrangement for measuring, in a tire testing machine, radial and axial forces at a wheel consisting of a pneumatic tire and a rim. The measuring axle, on which the wheel is rotatably disposed during the measuring run, has two cylindrical axle parts, of which the first, interior axle part is mounted so that it can be moved radially and frictionlessly in a straight line, and the second, exterior axle part, in axial direction, is frictionlessly located on the first axle part. For introduction of the axial forces, a first force measuring device is provided that is connected with a tension-compression rod that is rigidly connected with the second axle part, and for measuring the radial forces, a second force measuring device is connected between the base plate and the first axle part.
