A very simple and economic method for quickly repairing a puncture in a vehicle tire utilizes a screw having a concave slot beneath its head, with the circumference of the head portion cooperating with the slot to provide an edge which slightly cuts into the surface of the tire when the screw is inserted into the puncture. A sealing material such as an adhesive rubber is placed in the slot and seals the top of the puncture when the screw is threaded into the puncture hole. The design provides easy, quick, efficient and very low cost repairs for a puncture in a tire, not only for temporary repairs but for long term repairs. The design is simple and includes only two parts: a screw having a spiral thread by which the screw is affixed in the tire, and a concave slot under the screw head with the sealing material such as an adhesive or sticky rubber which is secured in the slot. The screw body is fixed in the tire hole and the head presses the sealing material into the hole.
