Process for retreading solid tires

An improved solid tire formed by the steps of:

• applying uncured tread rubber to a solid tire body to form a green assembly, said solid tire body having been previously cured;
• placing said green assembly in a C mold wherein said C mold comprises two halves and wherein each half comprises a spindle and wherein said spindles are dimensioned such that there is a gap therebetween when said C mold is in a closed position, said gap serving to allow said solid tire body to shrink during subsequent curing such that a portion of said solid tire body has an inner diameter that is less than the outer diameter of a corresponding rim for said solid tire body;
• closing said C mold to the closed position;
• and
• curing said green assembly within said C mold to form a cured assembly.
