As a preferred embodiment, the central straight groove 11, the central main groove 13, the shoulder main grooves 24 and the shoulder straight grooves 33 enhance the drainage performance of the tire under wet conditions and impart linearity and guidance to the tire; during driving, air and moisture brought in when the main tread 1, the 1/4 shoulder pattern areas 2 and the shoulder pattern areas 3 are in contact with the ground can be discharged through the central straight groove 11, the central main groove 13, the shoulder main grooves 24 and the shoulder straight grooves 33, so that the problems of skidding and noise generated during driving of the tire are reduced;

in this embodiment, as shown in fig. 2, the central main groove 13 and the shoulder main groove 24 are wider than the central straight groove 11 and the shoulder straight groove 33.

It should be noted that the central straight groove 11 is narrower than the central main groove 13, so that the air compressed on the main tread 1 is mainly discharged from the central main groove 13 during the running process of the tire, and the compressed air formed by the main tread 1 and the ground is discharged along the central main groove 13 in a single direction under a high-speed state, thereby reducing the frequency of the compressed air and reducing the noise; the shoulder main grooves 24 are wider than the shoulder straight grooves 33, so that air compressed on the main tread 1 during running of the tire is mainly discharged from the shoulder main grooves 24;

in this embodiment, as shown in fig. 2, the center tread 12 is plain, and the center tread 12 is smooth and flat.

It should be noted that the central straight groove 11 divides the main tread 1 into two halves equally, which enhances the drainage and linearity of the main tread 1, and the central tread 12 is smooth and plain, which enhances the tread rigidity of the main tread 1, makes the main tread 1 more wear-resistant, and enhances the guiding performance of the tire;

In this embodiment, as shown in fig. 2, the ribs 32 are arc-shaped, and the width of the ribs 32 gradually decreases from one end connected to the shoulder main groove 24 to the other end connected to the shoulder straight groove 33.

The inner shoulder pattern blocks 31 are divided into a plurality of groups of pattern blocks by the pattern ribs 32, the inner shoulder pattern blocks 31 and the shoulder main grooves 24 form closed spaces, and when a tire is in contact with the ground, compressed air formed by the tread and the ground in a high-speed state is discharged along the shoulder main grooves 24 in a single direction, so that the frequency of the compressed air is reduced, and the noise is reduced;

in this embodiment, as shown in fig. 2, one end of the pitch rib 34 is connected to the shoulder straight groove 33, and the other end is connected to the outermost side of the tire; 2 steel ribs 36 in a plurality of groups of the pitch blocks divided by the pitch ribs 34 of the outer shoulder pattern blocks 35 are transversely arranged, one end of each steel rib is connected with the shoulder straight groove 33, and the steel ribs 36 are arranged in parallel.

The pitch ribs 34 make the outer shoulder pattern blocks 35 different in arrangement size per pitch by applying a static gene technology, the steel ribs 36 are used for softening the rigidity of the outer shoulder pattern blocks 35 to enhance the grip capability of the tire, especially on a road which passes through a curve in a wet and slippery state, the inertia deviation of the vehicle can be effectively resisted, the stability of the vehicle can be kept, a water breaking film can be broken, the contact area between the tire tread and the ground is increased, the tire does not slip, and the driving safety is greatly improved.
