In the tire, the first group of blind holes and the second group of blind holes which are staggered are respectively arranged on the two opposite sides of the wheel body 200 in the tire body 10, so that the weight of the tire body 10 is reduced, the rolling resistance of the tire is reduced, the safety of the vehicle in the driving process is improved, and the problems that the existing solid tire body is heavy in weight, large in rolling resistance and not beneficial to guarantee of safety performance are solved; and the area of two adjacent second blind holes 221 and the area of two adjacent first blind holes 211 provide the holding power for the both sides of wheel body 200 respectively, the balance of the both sides of wheel body 200 has been guaranteed, the first blind hole 211 is just to the air current through-hole 230 that the part formed again with second blind hole 221, the gas of the both sides of wheel body 200 can circulate, make the good heat dissipation of matrix 10, therefore, the good heat dissipation of matrix has also been guaranteed through above-mentioned tire of present cover tire and matrix matched with, avoid the phenomena such as the tire burst takes place for the tire, have increased the life of tire promptly, guarantee the tire better and have stable security performance.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
