This invention provides a method for controlling the weight of a solid tire carcass and its application, relating to the field of tire carcass technology. The method includes the following steps: (a) weighing the base rubber after molding and comparing it to the standard weight of the base rubber to obtain a weight difference value; (b) correcting the amount of intermediate rubber based on the weight difference value from step (a), weighing the tire carcass after molding the intermediate rubber, and comparing it to the standard weight of the intermediate rubber tire carcass to obtain a weight difference value; (c) correcting the amount of tread rubber used in one stage based on the weight difference value from step (b), weighing the tire carcass after molding the first stage of tread rubber, and comparing it to the standard weight of the first stage of tread rubber tire carcass to obtain a weight difference value; (d) correcting the amount of tread rubber used in the second stage based on the weight difference value from step (c), and molding the tread rubber in two stages to obtain the finished tire carcass. This invention, through segmented weighing and multi-stage correction, gradually offsets the weight errors in each molding stage, achieving a tire carcass weight error of ±0.1 kg, far superior to existing weight control precision.
