The invention discloses a tire, comprising a tire crown, a tire shoulder, a tire sidewall, and a first belt ply, a second belt ply, a third belt ply and a fourth belt ply, and a first zero belt ply and a second zero belt ply which are wound in the circumferential direction of the tire, wherein the first zero belt ply and the second zero belt ply are arranged on the part of the tire shoulder and positioned at both sides of the third belt ply and the fourth belt ply. According to the invention, the middle part of the tire crown is of a four-layer belt ply structure of which the antiknock strength is obviously superior to that of the belt ply structure of the traditional tire, two zero belt plies are wound in the circumferential direction of the tire shoulder of the tire, so that the shoulder strength is improved, and the problems of shoulder separation and shoulder explosion caused by the four-layer belt ply structure are solved.
