The tire 1 shown in FIGS. 1 and 2 is a normal tire, and a composite tube 4 is loaded therein. The composite tube 4 includes ring-shaped first and second rings 1 along the tire 1.
The airtight chambers 2 and 3 are provided with air inlets 5 and 6, respectively. When air is sent into the airtight chambers 2 and 3 through the air inlets 5 and 6, the air pressures in the airtight chambers 2 and 3 become substantially equal. Note that FIG. 1 shows a cross section taken along the line AA 'in FIG.

Even if the air pressure in either of the first and second airtight chambers drops sharply due to puncture or deterioration of insect rubber, etc., the air pressure in the other airtight chamber remains, so that the vehicle can be safely driven without being pulled by the steering wheel. Can continue.

When the air pressure in one of the airtight chambers drops due to
It is pushed down by the air pressure in the other airtight chamber. Since the curved portion 12 increases the substantial thickness of the tire 1 on the ground contact surface, the risk of the tip of the nail 13 reaching the other airtight chamber and causing double puncture is eliminated.
