A multi-port tire pressure detecting system includes a plurality of pressure detection units and a pressure processing unit. Each of the pressure detection units is mounted to an inflation valve on a tire via a tire pressure inlet port, and includes an internal pressure detector and an outward projected pumping inlet port. The pressure processing unit includes a microprocessor, a transmitter, and a power supply connected to the microprocessor, the transmitter, and the pressure detectors for supplying power thereto. When the pressure detectors detect the pressure of tires, tire pressure data are generated. The generated tire pressure data are processed by the microprocessor and then transmitted by the transmitter to a receiving unit near a driver seat for display in real time. When a tire is indicated as having insufficient internal pressure, the tire may be conveniently inflated via the pumping inlet port of a corresponding pressure detection unit.
