A method for preparing a heavy-duty tire with a natural rubber (NR) modified by graphene/carbon blacks varying in particle size synergized with a vulcanization system is provided. Carbon blacks varying in particle size are subjected to surface modification to obtain an graphene oxide/carbon blacks varying in particle size aqueous dispersion. Subsequently, a graphene oxide/carbon blacks varying in particle size modified NR masterbatch is prepared using an aqueous-phase synergistic aggregating precipitating process. Finally, a natural rubber heavy-duty tire is prepared from graphene/carbon blacks varying in particle size synergistically vulcanized modified natural rubber through a molding process. Compounding of graphene with the carbon blacks varying in particle size is utilized to improve dispersion of reinforcing fillers within the rubber matrix. Adjustment of a ratio of a vulcanizing agent to an accelerator is utilized to regulate a cross-linked network structure of the rubber.
