The invention provides a tyre belt ply structure which comprises at least two belt plies attached to a tyre body. The first belt ply is located on the bottommost layer of all the belt plies and divided into a left portion and a right portion which are attached to the left side portion and the right side portion, deviated a distance from the center of the tyre, of the tyre body respectively; adhesive sheets are filled between the two portions of the first belt ply; other belt plies are sequentially attached to the first belt ply. The tyre belt ply structure further comprises the second belt ply, the third belt ply and the fourth belt ply; the second belt ply is attached to the first belt ply, and the width of the second belt ply is larger than the two ends of the outermost sides of the two portions of the first belt ply; the third belt ply is attached to the second belt ply, and the width of the third belt ply is smaller than that of the second belt ply; the fourth belt ply is attached to the third belt ply. According to the tyre belt ply structure, the disengagement phenomenon caused by the fact that one side of the interior of the tyre body is subjected to harmful factors such as stress can be significantly reduced, and early damage of the tyre can be effectively prevented.
