ABSTRACT OF THE DISCLOSURE: A mold for curing retreaded tires comprises a tubular drum having an axis and axially spaced ends and an inner tubular member substantially coextensive and coaxial with the tubular drum, the former and the latter circumferentially bounding an annular space. A partition extends substantially normal to the axis intermediate the ends between the tubular drum and the tubular member and subdivides the space into two annular compartments. The mold also includes a pair of doors, each mounted at one of the ends of the tubular drum for movement between a closed and an open position and each axially bounding a curing chamber including the respective compartment; each of the curing chambers is adapted to receive at least one retreaded tire to be cured therein. The curing mold of the invention allows to subject the tread band and partially the underlying carcass of a pneumatic tyre to a temperature which is substantially uniform along the entire tread band.
