A reinforcing tube for a tire is provided to widen the range of choice of tires and to achieve the run-flat effect of a tire by inserting to the inside of a tire. The reinforcing tube for a tire comprises ring type tubes(1) installed to each inside of both side walls(32) of a tire(3), and a support(2) installed between the ring type tubes. An external wall(11) of the ring type tube on the side wall direction is formed to a thickness of 4 millimeters or more and made of synthetic rubber, an internal wall(12) of the ring type tube of the support direction is equipped with many steel wires(13) to minimize deformation if high pressure air or silicon is filled up, and the support is composed of a central bar(21) and insertion bars(22) installed on both ends of the central bar to be projected by rotating the central bar. The reinforcing tube is installed by inserting insertion bars of a support into a central bar to minimize the length of the support and to locate ring type tubes in a tire, taking out the insertion bars of the support from the central bar to extend the length of the support and to fix the location of the ring type tubes, injecting high pressure air or silicon into the fixed ring type tubes to press side walls, attaching the tire to a rim and injecting air to the tire, and fixing the tire to a vehicle.
