ABSTRACT:
The present invention discloses a system for varying the inflation pressure in the tires of a vehicle in order to obtain an operator selected tire deflection. The system includes a source of pressure which is fluidly connected through an inflation valve to the tires which, upon actuation, increases the tire pressure. Conversely, a deflation valve is also connected to the tire and, upon actuation, exhausts fluid from the tires thus decreasing the tire pressure. A pressure sensor detects the pressure representative of the pressure within the tires and a further sensor detects the vehicle load while a switch arrangement allows the operator to select between at least two different tire deflection levels. An electronic control unit receives input signals from the pressure and further sensors as well as from the switch arrangement and selectively actuates the inflation or deflation valves until a tire pressure corresponding to the desired tire deflection is obtained.
