Title: METHOD AND SYSTEM FOR MEASURING AND ADJUSTING PRESSURE OF TYRES
Abstract:
Method and system for measuring and adjusting pressure of tyres of vehicles in order to set the appropriate pressure to a tyre when the latter is in temperature and pressure conditions different from nominal conditions, the method and system comprising the steps of measuring the pressure inside the tyre, measuring the temperature inside the tyre, calculating a pressure value equivalent to the nominal value as a function of said measured values, visualising the measured values, introducing said values in an air supplying machine, and supplying said calculated pressure to the tyre. The system for implementing said method comprises a thermocouple, a pressure tester provided with means in contact with the thermocouple, and an air supplying machine and a connector provided with means in contact with the thermocouple; or alternatively, the system comprises an emitting and sensing device arranged on the surface of the rim inside the tyre, a remote control apparatus operating with radiofrequencies' signals and an air supplying machine.
