The bead area of a pneumatic tire is vented of trapped air by inserting an air guide into the bead area from the outer side of the tire adjacent the tire wheel rim area, whereby the trapped air is guided from the bead area along the air guide to the outer side of the tire. The air guide is an elongated flexible member provided with an enlarged head at its inner end. It is inserted into the tire by an elongated hollow shaft provided with an exterior spiral screw thread. The air guide is inserted into the hollow bore of the shaft, with the enlarged head of the guide abutting one end of the shaft. The opposite end of the shaft is secured to the chuck of a conventional low speed reversible electric drill. The enlarged head of the air guide is provided with a plurality of spaced, outwardly projecting stops which serve to prevent retraction of the head and air guide from the tire. When the enlarged head has been inserted to the desired depth in the bead area, the drill is reversed to retract the screw threaded shaft. The enlarged head remains in the bead area and the elongated flexible air guide extends from the enlarged head to the outer surface of the tire. Excess length of the air guide is cut away at the tire surface.
