Method to detect a pressure loss in at least one vehicle tyre

The method involves acquiring a value of a parameter representative of vertical force (F1-F4) undergone by left and right rear and front wheels (11-14) in a motor vehicle. A value of an indicator is evaluated according to values of parameters obtained in the acquisition step. An eventual pressure loss in tyres of the front and rear wheels is detected according to the value of the indicator. An independent claim is also included for a motor vehicle including a unit for implementing a method for detecting pressure loss in tyres of front and rear wheels.
