A method of retreading a solid tire comprising the steps of:
- applying uncured tread rubber to the tire to form a green assembly;
- placing said green assembly in a C mold wherein said C mold comprises two halves and wherein each half comprises a spindle and wherein the spindles are dimensioned such that there is a gap therebetween when the C mold is in a closed position, said gap serving to allow the tire body to shrink during curing such that a portion of the tire body has a diameter that is less than the diameter of a corresponding rim for the solid tire;

- and
- curing the green assembly within the C mold to form a cured assembly.
