ような安全性の高いタイヤを目的とするものである。In the tire according to the above-mentioned conventional technique, if the tire of the automobile is punctured, the punctured tire will be replaced, but if the puncture of the tire occurs during running at high speed. Since the sudden braking action is not effective and the vehicle body is tilted due to the load, the steering operation becomes difficult and the vehicle body loses its balance, which may cause a serious accident. Flat tires on wheels, even when placed on an aircraft, have caused catastrophe. An object of the present invention is to provide a highly safe tire that does not lead to a major accident even if the tire is punctured.

Is a ring-shaped tread 11 similar to FIG.
A pair of sidewalls 12 are provided from both ends in the radial direction of the tire, and a bead pace 13 is provided at an end thereof, and a rim 15 having an external tire rim valve 14 is attached to the bead pace 13. Inside, an internal tire 102 (the shape of which is not specified) mainly made of acrylonitrile rubber, butyl rubber, natural rubber, recycled rubber or the like is provided. Even if a puncture occurs on the outer tire 101, the inner tire 102 is unlikely to cause crushing due to a sudden load. Therefore, it is possible to run for several tens of meters while maintaining the balance. This enables safe driving again.

In this case, the inner tire may be fixed to the rim with a mounting bolt (not shown) for attaching the inner tire to the rim, or the central portion of the contact surface with the rim may be fixed with an adhesive. You may fix it. Further, in order to facilitate the integration of the inner tire with the rim, if the inner tire is expanded and blown into the rim to be fitted and fixed to the dish-shaped portion of the rim, the inner tire can be attached without rattling. Further, the fitting portion may be fitted to the dish-shaped portion of the rim so as not to be inflated by air, adhered if necessary, and inflated by blowing air.

る。The outer diameter of the inner tire according to the present invention, that is, the distance defined by the center position of the inner surface of the rim and the center position of the inner surface of the tread of the outer tire (the height of the tire as shown in FIGS. 1 and 2). ) to when the h 1, the outer diameter (the height of the tire inside the tire overlapping at the same portion) and h 2, h 2
= H 1 × 80% or more does not have a sharp difference in diameter, so that even if the outer tire is punctured, it can be relatively easily supported by the inner tire, so that adverse effects due to load tilting can be prevented. Further, by setting the crushing strength of the inner tire to 80% or more of the crushing strength of the outer tire, the outer tire can be sufficiently supported by the inner tire when the outer tire is punctured. You can stop completely.

る。According to the present invention, since the tire has a double structure, even if the outer tire is punctured, it is supported by the inner tire, and the inner tire does not puncture for several tens of meters, and the load is changed. Since it does not move, there is no load collapse, and no trouble in scanning the steering wheel, the safety can be extremely enhanced. Especially, it is extremely effective when used as a front wheel of a large bus or truck or a tire for an aircraft. In addition, the inner tire does not hurt more than the outer tire, so it can be used again.
