[0002] Ultra High Performance (UHP) passenger car tires are widely used in high-performance and sports cars, which have high requirements for driving speed and handling performance. However, existing UHP tires have the following shortcomings:
[0003] 1. Insufficient drainage performance: In pursuit of grip, the tread pattern design is too aggressive, resulting in poor drainage performance. When driving on wet roads, hydroplaning is likely to occur, posing a safety hazard.
[0004] 2. Poor comfort: To ensure high-speed stability, the tire structure is relatively stiff, resulting in poor shock absorption and affecting ride comfort.
[0005] Therefore, this utility model provides an ultra-high performance passenger car tire that can take into account handling, safety, comfort and durability. Utility Model Content
[0006] This invention primarily addresses the technical problems of existing ultra-high performance passenger car tires, such as insufficient drainage performance, poor comfort, and insufficient wear resistance. It proposes an ultra-high performance passenger car tire to improve grip and drainage performance in both dry and wet conditions, reduce the risk of hydroplaning, and enhance driving safety and comfort in wet environments.
[0007] This utility model provides an ultra-high performance passenger car tire, comprising: a tire carcass;
[0008] Multiple longitudinal main drainage grooves are provided on the tire surface of the tire carcass;
[0009] The tire body has an inner tread pattern area on the inner side and an outer tread pattern area on the outer side.
[0010] Multiple first auxiliary drainage grooves and multiple second auxiliary drainage grooves are alternately arranged on the inner patterned area; a knife groove is also provided between adjacent first auxiliary drainage grooves and second auxiliary drainage grooves;
[0011] Multiple third auxiliary drainage channels and multiple fourth auxiliary drainage channels are alternately arranged on the outer patterned area.
[0012] Preferably, the first auxiliary drainage ditch, the second auxiliary drainage ditch, the third auxiliary drainage ditch and the fourth auxiliary drainage ditch are at an angle of 30°-45° to the main drainage ditch.
[0013] Preferably, there are four main drainage ditches; the width of the two middle main drainage ditches is greater than the width of the two side main drainage ditches.
[0014] Preferably, the groove is filled with hydrogenated solution-polymerized styrene-butadiene rubber.
[0015] Preferably, a buffer layer is provided between the tread and the belt layer.
[0016] Preferably, the buffer layer is made of natural rubber.
[0017] Preferably, the tread is made of solution-polymerized styrene-butadiene rubber.
[0018] Preferably, the tire body has a reinforcing layer on its sidewall, the reinforcing layer is made of nylon thread material, and the reinforcing layer is at a 30° angle to the vertical direction.
[0019] Preferably, the tire body has a ply layer.
[0020] Preferably, the fabric layer uses two layers of polyaramid fiber cords arranged in an alternating pattern, with the two layers of polyaramid fiber cords forming an 88° angle.
[0021] This utility model provides an ultra-high performance passenger car tire, which, through optimized tread pattern and tire carcass structure, has the following advantages compared to existing technologies:
[0022] 1. The main drainage ditch adopts an asymmetrical variable cross-section design, with the two middle main drainage ditches widened to enhance drainage efficiency. The main drainage ditch, the first auxiliary drainage ditch, the second auxiliary drainage ditch, the third auxiliary drainage ditch, and the fourth auxiliary drainage ditch form a highly efficient drainage network, significantly improving grip and drainage performance in both dry and wet areas, reducing the risk of hydroplaning, and enhancing driving safety in wetlands.
[0023] 2. The tire's inner tread blocks feature an asymmetrical design.

This design ensures excellent grip in both dry and wet conditions, improving handling precision and cornering stability.
[0024] 3. The tires utilize a high-strength, lightweight frame with a buffer layer between the tread and the belt layer. This absorbs road impacts, reduces vibration transmission, and improves comfort; it also suppresses standing wave phenomena at high speeds, enhancing safety. While ensuring high-speed stability, it significantly improves shock absorption comfort and reduces road vibration.
[0025] 4. The tread is made of solution-polymerized styrene-butadiene rubber, which improves wear resistance and heat dissipation performance, extends service life, reduces rolling resistance, and achieves energy saving and consumption reduction.
[0026] 5. This utility model tire achieves a comprehensive improvement in handling, safety, comfort and durability, meeting the high standards required by modern high-performance cars for tire performance. Attached Figure Description

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.
[0032] like Figure 1-3 As shown in the figure, an ultra-high performance passenger car tire provided in this embodiment of the present invention includes: a tire carcass; and multiple longitudinal main drainage grooves 1 are provided on the tire surface of the tire carcass.
[0033] The number of main drainage channels 1 is four; the width of the two middle main drainage channels 1 is greater than the width of the two side main drainage channels 1. The main drainage channels 1 of this utility model adopt an asymmetrical variable cross-section design, and the two middle main drainage channels 1 are widened to enhance drainage efficiency.
[0034] The tire carcass has an inner tread area 3 on the inner side and an outer tread area 4 on the outer side. Multiple first auxiliary drainage grooves 2 and multiple second auxiliary drainage grooves 5 are alternately arranged on the inner tread area 3; a sipe 6 is also provided between adjacent first auxiliary drainage grooves 2 and second auxiliary drainage grooves 5. The sipe 6 is filled with hydrogenated solution polystyrene-butadiene rubber, which adheres tightly to the ground during driving, further improving the tire's grip performance on the road surface.
[0035] Multiple third auxiliary drainage channels 7 and multiple fourth auxiliary drainage channels 8 are alternately arranged on the outer patterned area 4. The first auxiliary drainage channel 2, the second auxiliary drainage channel 5, the third auxiliary drainage channel 7 and the fourth auxiliary drainage channel 8 are obliquely intersecting the main drainage channel 1 at an angle of 30°-45°, forming an efficient drainage network, which significantly improves the drainage capacity of the wetland and reduces the risk of water skidding.
[0036] The first auxiliary drainage groove 2 is longer than the second auxiliary drainage groove 5; one end of the first auxiliary drainage groove 2 extends to the main drainage groove 1 that is close to it, and the other end extends to the inner edge of the tread; one end of the second auxiliary drainage groove 5 is a certain distance away from the main drainage groove 1 that is close to it, and the other end extends to the inner edge of the tread; the first auxiliary drainage groove 2 and the second auxiliary drainage groove 5 form an inner tread block.
[0037] The third auxiliary drainage groove 7 is longer than the fourth auxiliary drainage groove 8; one end of the third auxiliary drainage groove 7 extends to the adjacent main drainage groove 1, and the other end extends to the outer edge of the tread; one end of the fourth auxiliary drainage groove 8 is a certain distance from the adjacent main drainage groove 1, and the other end extends to the outer edge of the tread; the outer tread block is formed between the third auxiliary drainage groove 7 and the fourth auxiliary drainage groove 8. The outer tread block is wider than the inner tread block. The tread blocks of this utility model tire adopt an asymmetrical design. The outer tread blocks are larger and more rigid, providing excellent dry grip and cornering support; the inner tread blocks are smaller and have more fine sipes 6, enhancing wet grip.
[0038] There is one pitch between two adjacent first auxiliary drainage grooves 2 and one pitch between two adjacent third auxiliary drainage grooves 7. The tire of this utility model adopts a variable pitch design in both the inner tread area 3 and the outer tread area 4, which can suppress turbulent airflow and achieve a high efficiency and quiet effect.
[0039] The tread is made of solution-polymerized styrene-butadiene rubber SSBR M2520, which improves wear resistance and heat dissipation performance, extends service life, reduces rolling resistance, and achieves energy saving and consumption reduction.
[0040] Based on the above scheme, a buffer layer 11 is provided between the tread and the belt layer 10. The buffer layer 11 is made of natural rubber, which has high elasticity and high damping characteristics, can absorb road impacts, reduce vibration transmission, and improve comfort; it can also suppress standing wave phenomena during high-speed driving and improve safety.
[0041] The tire body has a reinforcing layer 9 on its sidewall, which is made of nylon thread. The reinforcing layer 9 is at a 30° angle to the vertical direction, and it can reinforce the tire sidewall, improving its strength and scratch resistance.
[0042] The tire body has a ply layer 12. The ply layer 12 is made of polyaramid fiber cord, which has high strength and low elongation, ensuring the strength of the tire body. The ply layer 12 consists of two layers of polyaramid fiber cord arranged in an 88° angle between them, which enhances tear resistance and high-speed stability.
[0043] This utility model provides a manufacturing process for ultra-high performance passenger car tires:
