A tire pressure warning device with adjustable pressure setting includes a case divided into a lower and an upper chamber and having a shoulder portion formed near a top thereof; a valve structure mounted in the lower chamber of the case; a membrane, a bushing, a push member, an elastic element, and a pressure-adjusting element sequentially mounted in the upper chamber of the case; and a cover connected to the top of the case. While the elastic element defines a basic pressure setting for the device to measure the air pressure inside a specific type of tire, a pressure-adjusting element with a suitable thickness may be selected to adjust the tightness of an elastic fixing element and thereby changes the pressure setting for the device, so that the device could also be used to measure the tire pressure of other different types of tires.
