本発明は、注型成形によるタイヤ基体にトレッドリング
を嵌合させることによって、Ｍ量が軽減できかつ転がり
抵抗を減じうる空気入りタイヤに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pneumatic tire in which the amount of M and rolling resistance can be reduced by fitting a tread ring to a cast-molded tire base.

が知られている。At the same time as fitting the tread ring onto the base of the tire,
Pneumatic tires are known that include a fixed tread ring that inflates the base by applying air pressure from inside the base and fixes the tread ring by the frictional force generated between the fitting parts.

問題がある。However, with the structure described above, the rubber layer between the reinforcing body and the inner surface of the tread ring is easily destroyed due to the presence of the reinforcing body, and since the tire has a double structure, the thickness of the tread part is not uniform. As a result of the tire being thicker than a conventional tire formed as a tire, there is a problem that the weight of the tire is heavy and the rolling resistance is large, resulting in an increase in fuel consumption.

The publication proposes a tread ring in which a supplementary IJIN is further interposed inside the reinforcing body. Although the above proposal increases the strength of the tread ring, it does not reduce the weight or rolling resistance. Moreover, since the tread ring is fitted onto the base body, the fitting surface must be formed with high precision, which requires time and effort to manufacture.

決しうる空気入りタイヤの提供を目的としている。The present invention is based on forming the tire base from a polymeric material and interposing two reinforcing layers with cords in different directions in the tread ring, thereby reducing the weight of the tire and reducing rolling resistance. The object of the present invention is to provide a pneumatic tire that can prevent the risk of punctures, improve driving safety, and solve the aforementioned problems.

で重ね合わされる。The overhanging piece 21 located on the side of the ground contact surface of the tread portion has a bent portion on its inner circumferential surface that is bent into a substantially diagonal two-shape starting from the root of the overhanging piece 21 and ending at the tip. The overhanging piece 22 forms a hook-shaped portion 23 that is similar to the overhanging piece 2.
The overhanging piece 21.22 has a hook portion 24 on its outer circumferential surface that is bent into the same shape as the hook portion 23 of No. 1.

するためである。The overhanging pieces 21 and 22 are stacked so that the overlapping portion has a wall thickness T1 thicker than the other crown portion wall thickness T2. 22 are formed so as to bulge inward from the inner cavity surface. Further, the width dimension of the overhanging pieces 21 and 22, that is, the overlapping width W, is about 5 cranes. In addition, by providing the hook-shaped portions 23.24 on the overhanging pieces 21.22 and engaging them as in this embodiment, it is possible to fix both of them, which is normally required when joining and integrating the semi-annular members 19.20.

める。As mentioned above, in the pneumatic tire of the present invention, the tire base is formed by cast molding of a polymer material, so the rubber layer of the tire base is denser and lighter in weight than in the case of a tire base formed by conventional molding methods, and the dimensions are also reduced. It becomes easier to ensure accuracy. Furthermore, by increasing the rigidity of the tire base, combined with the provision of the first and second reinforcing layers near the inner surface of the tread ring, it is possible to reduce the rolling resistance of the tire and reduce fuel consumption. It also prevents damage to the tire base and improves the safety of the tire by suppressing the occurrence of punctures.
