A sensing device of tire defects using a piezosensor is provided to alarm pneumatic pressure shortage of a tire or a flat tire to a driver by continuously sensing vibration of the tire during high speed driving. A sensing device of tire(60) defects using a piezosensor comprises a piezosensor unit(20), an electronic control unit of a vehicle and an alarming unit. The piezosensor unit is installed in one portion of a suspension unit(10) and obtains an electrical signal due to vibration. The electronic control unit receives information sensed by the piezosensor unit, compares and judges the information each other. The alarming unit is connected to the electronic control unit and alarms the information to a driver.
