A pneumatic control device is provided designed to work with self-inflating inner tubes and tires, specifically for bicycles or wheelchairs. The device distinguishes a stem assembly and an air control assembly. The device allows users to set a desired pressure and maintains that constant pressure over time, thereby eliminating the need to manually re-fill the tires. The device is compatible with current rims and tires and requires no modification to be installed to existing rims. The device works by regulating the intake of air from the atmosphere into the self-inflating pumping mechanism. Once the desired pressure is reached, the system stops new air from entering the self-inflating mechanism.
