[0026] Based on people's requirements for vehicle driving comfort and safety, it is necessary to develop a high-performance tire with better grip pattern to achieve precise control, which is specifically manifested in providing more precise control and better stability during high-speed steering and cornering. Multiple geometric pattern grooves cut the water film at multiple angles at different positions on the tread to ensure effective contact with the road surface and achieve reliable grip, thereby ensuring that the tire has excellent drainage performance when it rains, and has stable cornering performance and handling performance on dry and wet roads, and provides a relatively comfortable and quiet driving experience when driving at high speeds.

[0027] refer to Figure 1 and Figure 2, the embodiment of the present application provides a tire, the tire has a circumferential surface, wherein the position installed on the inner side of the vehicle is the inner side of the tire, and the position installed on the outer side of the vehicle is the outer side of the tire. Along the direction from the inside to the outside, the circumferential surface is provided with a first longitudinal groove 1, a second longitudinal groove 2, a third longitudinal groove 3 and a fourth longitudinal groove 4 spaced apart from each other, so as to divide the circumferential surface into an inner shoulder area 5, an inner rib area 6, a central rib area 7, an outer rib area 8 and an outer shoulder area 9. That is to say, along the direction from the inside to the outside, the inner shoulder area 5, the first longitudinal groove 1, the inner rib area 6, the second longitudinal groove 2, the central rib area 7, the third longitudinal groove 3, the outer rib area 8, the fourth longitudinal groove 4 and the outer shoulder area 9 are arranged in sequence. The first longitudinal groove 1, the second longitudinal groove 2, the third longitudinal groove 3 and the fourth longitudinal groove 4 extend along the circumferential direction of the tire, and are arranged at intervals along the direction from the inside to the outside of the tire. The first longitudinal groove 1, the second longitudinal groove 2, the third longitudinal groove 3 and the fourth longitudinal groove 4 are main grooves of the tire, which can provide good drainage performance, improve the braking and braking of the tire when the road surface is wet, and improve driving safety. An inner rib area 6 is provided between the first longitudinal groove 1 and the second longitudinal groove 2, a central rib area 7 is provided between the second longitudinal groove 2 and the third longitudinal groove 3, and an outer rib area 8 is provided between the third longitudinal groove 3 and the fourth longitudinal groove 4. The wider inner rib area 6, the central rib area 7 and the outer rib area 8 increase the contact area with the ground, which can increase the wear mileage while reducing the rolling resistance, and improve the cruising range of the vehicle. It should be understood that the width of any one of the first longitudinal groove 1, the second longitudinal groove 2, the third longitudinal groove 3 and the fourth longitudinal groove 4 is greater than the width of any one of the patterns in the inner shoulder area 5, the inner rib area 6, the central rib area 7, the outer rib area and the outer shoulder area 9, and the above-mentioned pattern includes a pattern groove or a knife groove.

[0028] The inner shoulder area 5 has a plurality of first pattern portions, which are spaced apart along the circumference of the tire; the inner rib area 6 has a plurality of second pattern portions, which are spaced apart along the circumference of the tire; the central rib area 7 has a plurality of first sipes 71, which are spaced apart along the circumference of the tire; the outer rib area 8 has a plurality of first grooves 81, which are spaced apart along the circumference of the tire; the outer shoulder area 9 has a plurality of third pattern portions, which are spaced apart along the circumference of the tire; wherein the second pattern portion includes a second sipe 61 and a second groove 62, which are spaced apart along the circumference of the tire, the width of any one of the first sipe 71 and the second sipe 61 is smaller than the width of the first groove 81, and the width of any one of the first sipe 71 and the second sipe 61 is smaller than the width of the second groove 62.

[0029] The wide inner rib area 6, the central rib area 7 and the outer rib area 8 are arranged in the center of the tire to increase the tire base area, increase the wear mileage and reduce the rolling resistance, and improve the vehicle's cruising range; and can improve the grip to achieve instant response, making wet braking more agile. The multiple first pattern parts located in the inner shoulder area 5 and the multiple third pattern parts located in the outer shoulder area 9 extend along the width direction of the tire from the inside to the outside, which can assist in drainage and improve the tire's grip. In addition, the extension direction of the first pattern part and the third pattern part is at an angle to the rolling direction of the tire, which can enhance the tire's grip and effectively prevent side slip. The first sipe 71, the second sipe 61, the first pattern groove 81 and the second pattern groove 62 divide the tire into multiple small areas, each of which is separated, and the air is blocked between the small areas, reducing the noise generated by air squeezing, thereby achieving noise reduction; at the same time, it can respond to the change of operation immediately, and can start and stop quickly on both dry and wet roads, effectively preventing hydroplaning and increasing wetland safety. The first tread portion, the first tread groove 81, the first sipe 71, the second sipe 61, the second tread groove 62 and the third tread portion on the entire tire adopt various pitches to ensure grip while improving driving comfort, reducing noise and improving vehicle endurance performance.

[0030] Specifically, along the direction from the inside to the outside of the tire, the width of the fourth longitudinal groove 4 on the outside is the smallest, and the main function of the outside is grip.
