The present invention relates to a tire damage test device which includes fixing portions for air absorption and discharge each formed with a shield type frame and coupled in a direction in which outer peripheral surfaces face each other with respect to a tire; and a fixing portion for air blockage, wherein the fixing portions for air absorption and discharge each includes an air absorption and discharge terminal formed of an air suction hole to provide air supplied from an outside pump to the inside of the tire while the tire is in an air blockage state by the fixing portions for air absorption and discharge coupled to the fixing portion for air blockage with respect to the tire, and an air discharge valve formed to discharge the air supplied inside the tire through the air suction hole to the outside. A problem of conventional tire damage test devices in which a different device is required for various tire sizes is solved, thereby using the two frame-like fixing portions for air absorption and discharge for air blockage and the fixing portion for air blockage to test a problematic tire regardless of the size of the tire. Also, excess pressure is limited when introducing air inside the tire while the tire is in the air blockage state, thereby preventing the tire from being damaged or having a damaged portion enlarged or extended, and providing an optimal structure in which the air blockage state of the tire is maintained for a long period by the two frame-like fixing portions for air absorption and discharge for air blockage and the fixing portion for air blockage. |
