In a tyre pressure control system (1) for varying the air pressure in vehicle tyres (2) while driving, which has a compressed-air source (3), which has an overflow valve (4) and is connected to the tyres (2) via supply lines (5), control valves (6), rotors (7) and at least one relay valve (8) are connected into the supply lines. The pressure to be regulated via the relay valve (8) is preselected via a control valve (10). Located in the branch line between the control valve (10) and relay valve (8) is an electromagnetically operable or pressure-operable 3/2 way valve (9 and 9', respectively), which can be switched through manually by an on/off switch (13), in order to set the control system in operation. Shutting down the system (1) via the 3/2 way valve (9 and 9', respectively) is performed by utilising the air flowing out at the overflow valve (4) in the case of an increase in pressure in the tyre, and at the relay valve (8) in the case of a drop in pressure. The ventilation process is automated by the pressure-controlled shutdown, and the control process is reduced overall to a minimum (Figure 1). <IMAGE>
