Before describing embodiments of the present application, some terms or concepts related to the embodiments of the present application are explained.

The sidewall S/W insertion amount refers to the number of steel wires and nylon wires inserted into the sidewall during the production process of the tire. These steel wires and nylon wires are important components of the tire and they can enhance the strength and stability of the tire. In general, the greater the amount of sidewall S/W insertion, the better the performance of the tire.

Exemplary embodiments of the present application are described below with reference to the accompanying drawings.

Referring to fig. 1, there is shown a narrow running surface high aspect ratio light truck radial tire comprising: tread 01, second belt 02, first belt welt 03, first belt 04, carcass 05, inner liner 08, sidewall 06, bead wire 07, wherein:

The carcass layer 05 is disposed over the inner liner 08.

According to some embodiments, the inner liner 08 is a layer of rubber material inside the carcass for protecting the tire internal structure, sealing gas and liquid inside the tire.

The first belt 04 is disposed over the carcass layer 05. According to some embodiments, the carcass layer 05 is an important component of the internal structure of the tyre. It is typically made of multiple layers of high strength fibrous material (such as steel wire, nylon or polyester cords) cross-aligned and impregnated with rubber. The main function of the carcass layer is to bear and transfer the load of the vehicle, maintain the shape and stability of the tire, and resist impact and wear from the road surface. The first belt layer 04 is a first cord layer in a carcass, is made of steel wires or nylon and other materials, and is used for enhancing the strength and stability of the tire. One or more belt layers are typically disposed over the carcass layer during tire manufacture to increase the load bearing and impact resistance of the tire.

The second belt 02 is arranged above the first belt 04;

According to some embodiments, during the design and manufacturing process of the tire, there may be different arrangements and numbers of different belt layers to meet the needs of different types of tires and applications. The second belt layer 02 is arranged above the first belt layer 04, so that the bearing capacity and the impact resistance of the tire can be further increased through the structure of a double-layer belt layer.

The first belt welt 03 is at two side edges between the first belt 04 and the second belt 02, so that the first belt 04 and the second belt 02 are firmly connected.

According to some embodiments, since the belt layers are woven from a plurality of fine cords, there may be a certain gap or loosening phenomenon between the belt layers. To strengthen the connection between the belt layers, the first belt welt 03 is added between the first belt 04 and the second belt 02, the first belt welt 03 is positioned at two side edges of the first belt 04 and the second belt 02, the connection strength between the first belt 04 and the second belt 02 is enhanced, and the whole tire is firmer and more stable.

The tread 01 is arranged on the second belt layer 02, and the sidewall 06 is smoothly connected with the tread 01.

According to some embodiments, the tread 01 is provided on the second belt 02, the tread 01 being a layer of rubber material on the surface of the tyre, in direct contact with the road surface, providing traction and grip for the vehicle. Providing the tread 01 on the second belt 02 can enhance the bearing capacity and impact resistance of the tire and improve running safety.

According to some embodiments, the sidewall is a side portion of the tire for protecting the tire internal structure and sealing gas and liquid inside the tire. The smooth connection between the side wall 06 and the tread 01 ensures the overall strength and stability of the tire, reduces vibration and noise, and prolongs the service life of the tire.

The bead wire 07 is located at the bead opening of the tire.

According to some embodiments, said bead wire 07 is located at the bead of the tyre. The bead is an opening portion in the interior of the tire for injecting or discharging gas and liquid into or out of the tire. Because the position of the embryo mouth is special, special reinforcement treatment is needed to ensure the overall strength and stability of the tire. In the design scheme of the application, the bead wire 07 is arranged at the blank mouth of the tire, so that the bearing capacity and the impact resistance of the tire can be enhanced, and gas and liquid leakage can be prevented.

Wherein the cap ply layer located above the second belt 02 is omitted.

According to some embodiments, the cap ply is another ply of cords in the carcass, which is positioned over the belt layer for enhancing the load bearing and impact resistance of the tire. In the design scheme of the application, the requirements of bearing capacity and impact resistance are met under the condition of omitting the cap ply by adjusting the design of the parameters of the included angles of the first belt ply 04, the second belt ply 02 and the axial direction and the dual reinforcement adjustment of the bead wires 07, and the cost and weight can be reduced and the fuel efficiency can be improved by omitting the cap ply.

Referring to fig. 1, the first belt layer 04 forms an included angle of 20 degrees with the axial direction, and has a width of 105mm and a thickness of 1.2mm.
