PURPOSE:To make repairs so easy as well as to improve the extent of safety, by fusing a pressure sensitive adhesive, being semi-coagulatory and having pliable puncture hole closability, on a tire inner surface. CONSTITUTION:A semi-coagulatory pressure sensitive adhesive 2 of silicone, pliable crude rubber, etc., is fused on an inner surface of a tire 1. In this constitution, when a nail 3 is stuck in the tire, this semi-coagulatory pressure sensitive adhesive 2 is filled up in a clearance between the nail and the tire by air pressure inside the tire, preventing an air leakage from occurring. And, when the nail is pulled out, the adhesive 2 is extruded outward from the puncture hole by the air pressure, and it is exposed to the outside air, whereby it is solidified and the puncture hole is closed up. With this constitution, puncture repairs come so easy.
