The invention discloses a wireless wheel diameter measuring instrument which comprises a positioning frame, a measuring assembly, a displacement sensor, a CPU module and a display screen. A positioning piece used for fixing the positioning frame is installed on the positioning frame, the measuring assembly comprises a measuring frame installed on the positioning frame and a movable frame installed on the measuring frame, the measuring frame is provided with a first fixed measuring end and a second fixed measuring end, and the movable frame is provided with a movable measuring end. During measurement, the first fixed measuring end, the second fixed measuring end and the movable measuring end abut against the outer wall surface of the wheel. In the initial state, the first fixed measuring end, the second fixed measuring end and the movable measuring end are located on the same straight line, the displacement sensor is installed on the movable frame, the CPU module is installed on the measuring frame and electrically connected with the displacement sensor, and the display screen is installed on the measuring frame and electrically connected with the CPU module. According to the technical scheme, measurement parameters can be read easily through the display screen, manual reading errors are eliminated, and the testing efficiency and the working efficiency are improved.
