Using the tire inflator configured as described above, a pneumatic tire of size 185 / 65R15 and a tire-rim assembly composed of a 6J-15 wheel rim were subjected to inflation experiments and compared with the results of the conventional apparatus. Here, as shown in FIG. 4, the conventional device is used for a tire-rim assembly that is placed horizontally on a mounting table 34.
An airtight plate that presses against the edge of the flange of the wheel rim
35 and the hermetic ring 36 surrounding it and contacting the side wall near the bead portion of the tire were sequentially lowered and injected from the air supply port 38 through the hermetic chamber 37 between the hermetic plate 35 and the hermetic ring 36. Air from one side by filling compressed air through the gap between the bead portion and the bead seat of the wheel rim on the front side of the pneumatic tire and filling the airtight ring 36 under pressure contact by the airtight plate 35 This is a method for filling. In the comparative test, for the inflated tire wheel, the distance between the rim line of the tire and the outer periphery of the rim flange was measured at 36 places on each of the front and back surfaces of the tire, and the average value was evaluated. The results are listed in the following table.
