Abstract: While the rise of electric vehicles, silent tires and tire repair agent are also becoming more common, however, for the compatibility of silent tires and tire repair agent, which need to conduct in-depth research on it. First of all, monitored the air tightness of the punctured tires repaired by the tire repair agent, and found that the tire don't leak, indicating that the silent tires does not affect the function of tire repair agent to repair tire. In addition, designed four test schemes, and tested the decibel value of cavity noise of the tires with different schemes by comparison method. It was found that the cavity noise value of tires with tire repair agent did not significantly deteriorate, indicating that the use of tire repair agent does not affect the function of silent tires to optimize cavity noise. So silent tires and tire repair agent compatibility is good, the two do not affect each other's function.
