Claim:
1. A tyre pressurisation arrangement on a vehicle in which the pressurisation of the tyre is controlled by a vehicle control unit and the vehicle control unit is notified of a desired tyre pressure or desired tyre volume, the tyre pressurisation arrangement comprising a control valve positioned between a vehicle air supply and the tyre, and a first pressure sensor on a first side of the control valve and a second pressure sensor on a second side of the control valve, and further characterised in that an air flow rate in a supply line to the tyre is established so that the time to pressurise the tyre to the desired tyre pressure/volume is calculable from the air flow rate, or wherein the time taken to pressurise the tyre to an interval pressure/volume is calculable, said interval pressure/volume being between a current tyre pressure/volume and the desired pressure/volume, wherein the air flow rate is calculated by taking the pressure differential between the first pressure sensor and the second pressure sensor.
