1. A rim for a wheel, including a measuring system to detect a vertical load applied to the wheel in operating conditions with wheel mounted with horizontal rotation axis,
the measuring system comprising:
a sensor to detect a deformation of the rim and to transmit a deformation signal related to the detected deformation, and
a processing unit, operatively connected to the sensor, configured to receive the deformation signal, and to determine the vertical load applied to the wheel, based on the deformation of the rim detected by the sensor,
the processing unit is configured to:
store measurements made by the sensor and detects a first LMIN value of absolute minimum, a second LMAX value of absolute maximum and a Lt_med value of relative minimum of the deformation signal generated by said sensor during a rotation of the rim, and
calculate the value of the vertical loads acting on the wheel, based on the detected a first LMIN value of absolute minimum, the second LMAX value of absolute maximum and the Lt_med value of relative minimum of the deformation signal generated by said sensor.
