欠点があつた。 A conventional vehicle tire has a bead portion, a sidewall portion, and a tread portion that are integrally formed to be attached to a rim. For this reason, when the tread portion, which is relatively subject to wear and tear, wears out, the tire must be replaced with a new tire even though the remaining portions are still usable, which is extremely uneconomical. In addition, for construction vehicles, the type of tire is selected depending on the purpose of the work (the shape of the tire reed is selected that is suitable for the work environment).
However, in this case, the entire tire had to be replaced, which was a big burden on the equipment.

The outer tire includes an inner bead portion, a sidewall portion, an outer bead portion located outside the sidewall portion, and a thin flexible top portion forming an outer peripheral portion of the inner tire. a bead portion engaging an outer bead portion of the inner tire and a rigid tread portion covering the top portion of the inner tire, wherein the top portion of the inner tire is formed from a thin rubber layer containing a nylon fabric layer therein. The outer bead portion of the inner tire includes a bead wire made of a bundle of flexible and non-stretchable fibers such as glass fiber or rayon, and the nylon cloth layer of the top portion is supported at both ends by the bead wire. The tire is characterized in that a radial uneven portion is provided between the outer bead portion of the inner tire and the bead portion of the outer tire so as to engage with each other in order to prevent relative movement of both tires in the circumferential direction.

イラーを使用する。 The inner bead portion 8 of the inner tire 2 fixes the inner tire to the rim 6 similarly to the bead portion of a conventional tire, and includes a bead wire 20 made of a strong high-carbon steel wire bundle inside, and the bead wire connects the carcass 2 to the rim 6. supports the inner edge of carcass 22
The frame of the tire, which functions to maintain the tire's air pressure and withstand loads and shocks, is a ply made of threads of nylon, rayon, polyester, etc., woven in a straight weave and covered with a thin rubber layer. It is formed in multiple layers depending on the application, for example, 2 to 4 layers for tires for passenger cars, and about 40 layers for tires for construction machinery. Note that the bead portion 8
Since the surrounding area is easily damaged by contact with the metal rim 6, it is reinforced with a rubberized canvas called a chauffeur (not shown), similar to conventional tires.
Further, a Δ-shaped rubber bead filler is used to make the relatively hard bead portion 8 conform to the flexible sidewall portion 10.

The breaker or belt 24
is the carcass 2 at the center of the sidewall part 10.
2 placed on the outside. The breaker 24 serves as a reinforcing material to reduce the impact received from the outside and to prevent scratches generated on the sidewall portion from directly reaching the carcass 22 when the breaker 24 is supported. Made of nylon cord layer. In the case of a belt, in addition to the above-mentioned breaker function, the rigidity of the sidewall part is increased and the carcass 22
It also functions to tension the cord laterally, and for this reason, it is desirable to use a non-stretchable cord such as rayon, steel, or glass fiber.

The bead wire 26 must be flexible in order to fix the outer tire 4 which is deflected by the load, and therefore the bead wire 26 is made of a flexible and non-stretchable material made of a fiber bundle such as glass fiber or rayon. It consists of The bead wire 26 supports the outer end of the carcass 22 and also supports the end of a nylon layer 28 within the top portion 14, which will be described below. In addition, it is desirable that the area around the outer bead portion 12 is also reinforced with a rubberized canvas similarly to the inner bead portion 8. Further, a groove extending in the tire radial direction is formed on the outside of the outer bead portion 12, and a rib is formed on the inside of the bead portion 16 of the outer tire 4, and by engaging the groove and the rib, a gap between both tires is formed. It is desirable to prevent relative circumferential movement.

とにより容易に修理することができる。 Next, the top portion 14 of the inner tire is made of a thin rubber layer containing a thin nylon cloth 2.8, preferably nylon 6 or nylon 66, braided in a bias shape around the inner diameter, and both ends of the nylon layer 28 are connected to the outer beads described above. It is supported by a bead wire 26 of section 12 . Therefore, although the top portion has sufficient flexibility, it does not inflate excessively due to air pressure. If the top portion 14 is punctured due to penetration by a rock, nail, etc., it can be easily repaired by pasting a similar canvas.
