The invention relates to a tire tread with a concave bottom surface and a tire crown structure applying the same. A concave-convex type groove along the length direction of the tire tread is formed in the bottom surface of the tire tread with the concave bottom surface, the width of the concave-convex type groove is consistent with the width of a belt ply to be combined with the tire tread, and the shape of the concave-convex type groove is matched with the concave-convex shape of the top surface of the belt ply to be combined with the tire tread. The tire crown structure comprises the tire tread and the belt ply, wherein a belt ply with a top surface in the concave-convex shape which is of a layered overlaying structure is adopted as the belt ply, and the tire crown structure is characterized in that the tire tread with the concave bottom surface is adopted as the tire tread, the width of the concave-convex type groove in the bottom surface of the tire tread is consistent with the width of the belt ply, and the shape of the concave-convex type groove is matched with the concave-convex shape of the top surface of the belt ply. The tire tread with the concave bottom surface can reduce the tire tread deformation, shorten the rolling time, and can also well improve the gas trapping phenomenon at steps of the belt ply after rolling, raise the tire inspection qualified rate and prolong the service life.
