1. A mobile test rig for testing a wheel-tire assembly, said test rig comprising:
- a self-driven platform, capable of following rectilinear and circular trajectories on a test track,an instrument module mounted on said platform and configured to test said wheel-tire assembly, said instrument module being configured to place the wheel-tire assembly in contact with said test track, to orient said wheel-tire assembly in all directions, to lean the wheel-tire assembly, and to apply a vertical effort to the wheel-tire assembly;
first swivelling axles mounted to said platform and equipped with suspensions and driving wheels in contact with said test track;
a processing unit associated to a memory and configured to control said instrument module and said first swiveling axles; and
means for controlling a test cycle permitting orientation of the wheel-tire assembly, and a load applied to said assembly.

21. A process of testing a tire with a test rig, said method comprising:
-
positioning the test rig in one position of a test track; learning an ideal trajectory, by moving the test rig at low speed along a longitudinal axis of the track, with acquisition of points of the trajectory using the positioning system; and performing one or more test steps. - View Dependent Claims (22)
