A giant tire curing bladder, relating to the technical field of giant tire curing bladders. Said curing bladder comprises an annular bladder body (1), two ends of the bladder body (1) each being provided with a bladder shoulder (2), a bladder side (3) and a bladder neck (4) which are bent toward the center of the bladder body, and the thickness of the bladder neck (4) gradually reducing toward the middle of the bladder. The specific structural dimension parameters are designed according to the dimension parameters of the 59/80R63 tire, and the outer surface thereof is provided with non-smooth discharge tread patterns. Compared with the prior art, the giant tire curing bladder matches the 59/80R63 tire in terms of specifications, and the designs of the profile parameters of the curing bladder and the discharge patterns on the outer surface are optimized, and are more suitable for curing and molding of the 59/80R63 tire, avoiding folding, air clogging and layer separation in a tire during curing of the giant tire, greatly improving the qualification rate of tires, preventing the tires from being unqualified in specifications and dimensions, and reducing the waste of raw materials and labor force.
