The pressure controller has an electronic housing enclosing a logic control system. The keyboard, linked to the controller, has visible tire state indicators and means for displaying a correction or tire pressure level values. The system includes an air loss sensor and locator. The system includes different pressure values for load state, full, half, or empty and for different types of terrain, as well as an overspeed indicator. System for regulating the pressure inside a pneumatic tire having an external envelope (3) mounted on a wheel rim (2). The tire has an internal envelope (5) at the rim base which forms an high pressure air reservoir. A first actuator (6) integrated into the envelope (5) allows air to pass to the external envelope (3) to maintain set air pressure. A second actuator (8) in the external envelope allows evacuation of air towards the exterior. An electronic system (17) is designed to emit data to one or the other actuators (6,8) and/or receive data from sensors (7,9) for control of pressure and temperature in the external envelope (3) and/or internal envelope (5). The electronic system controller (18) and a keyboard (19) controls the value of pressure inside the external envelope between a minimum and maximum as a function of a logic controller operating with a knowledge of exterior conditions affecting the tire and ensuring a permanent control of the tire pressure value.
