[0012] Compared with the prior art, the beneficial effects of the present invention include at least:

[0013] The tire is provided with an inner air retention layer, a cord cross layer and a tread layer from the inside to the outside. The wire ring is a steel wire connected to both sides of the cord cross layer, which provides stable support for the tire, can effectively prevent excessive deformation of the tire and provide external support. In addition, the wire ring cooperates with the internal inner air retention layer to enhance the sealing of the tire and prevent gas leakage when the tire is hit or punctured.

[0017] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0018] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0019] Reference Figure 1-2The utility model provides a tubeless racing road car vacuum tire, which includes, from inside to outside, an inner air-retaining layer 1, a cord cross layer 2 and a tread layer 3. The two sides of the cord cross layer 2 contain steel wire rings 4 for support. The inner air-retaining layer 1 covers the inner side of the tire and is used to cooperate with the wheel hub to contain gas. The inner air-retaining layer 1 is a polymer rubber layer. The inner air-retaining layer is a polymer rubber layer. When the tire is punctured, stabbed or collided while driving on the road, the polymer rubber layer located inside can effectively block the impact from the outside after being buffered by the tread layer 3 and the cord cross layer 2, and prevent the gas inside the inner air-retaining layer 1 from leaking due to puncture, thereby improving the experience of the driver and passengers.

[0020] In one embodiment, a smooth surface is formed on the symmetrical midline of the outer surface of the tread layer 3, and a first groove 5 and a guide groove 6 are arranged on both sides of the smooth surface near the symmetrical midline. The first groove 5 is opened on both sides of the symmetrical midline and is equidistantly distributed in the extension direction of the symmetrical midline of the tire. The guide groove 6 is located on both sides of the first groove 5 and connected to the side of the tire to drain the water from the tread edge. The middle is a smooth tread, and the shape of the first groove 5 and the guide groove 6 is, for example, an arc groove, and the first groove 5 and the guide groove 6 are also not connected. The guide groove 6 is located on both sides of the tire. At the moment of contact with the ground, the water flow contacted by the tread part will flow away through the guide groove 6 to avoid water between the tread of the tire and the ground, thereby reducing friction.

[0021] In one embodiment, nylon yarn 7 is further connected to both sides of the tread layer 3, and the rubber coating thickness of the nylon yarn 7 is 0.37 mm. After inspection, when the rubber coating thickness of the nylon yarn 7 is 0.37 mm, the bead structure can stably protect the side of the tire and prevent the nylon yarn 7 from falling off and separating.

[0022] In one embodiment, a wear-resistant layer 8 is provided at the joint between the outer side of the nylon yarn 7 and the hub. The wear-resistant layer 8 can protect the wire ring 4 and prevent the wire ring 4 from being damaged.

[0023] In one embodiment, the tread layer 3 is further formed with a sector pattern group 9, which includes a plurality of diamond particle blocks evenly distributed on the outer surface of the tread layer 3, providing ground bearing and forward power, and improving acceleration performance and cornering control performance.

[0024] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the utility model.
