1. A central tire inflation system for a work vehicle supported by a set of inflatable wheels the work vehicle couplable to an implement, the central tire inflation system comprising:
- a load transducer coupled to the work vehicle and configured to sense a load of the implement and to generate load signals representative thereof;
an electronic control unit coupled to the load transducer configured to receive the load signals and to generate control signals at least partly in response thereto;
an air manifold configured to receive the control signals from the electronic control unit, the control signals controlling actions of the air manifold to regulate the air supplied to the set of inflatable wheels.

Abstract
A central tire inflation system for a work vehicle is presented. The central tire inflation system controls the inflation pressure in the tires of a work vehicle. The central tire inflation system may be placed in an automatic or manual mode. In the automatic mode, the system makes changes to the tire pressures according to the tire parameters, terrain conditions, and the operating loads placed on the tires.
