A PROCESS FOR RECAPPING PNEUMATIC RADIAL TIRES ABSTRACT OF THE DISCLOSURE A process is disclosed for recapping a pneumatic radial tire including a carcass toroidally extended between a pair of bead portions and composed of a ply or plies having cords radially arranged, and a belt composed of three or more cord-arrayed layers arranged on a radially outer side of a crown portion of the carcass and having a split structure in which a central portion of a radially innermost cord-arrayed layer is removed. A base tire is obtained by removing the other cord- arrayed layer or layers positioned radially outwardly from the radially inner two cord-arrayed layers as well as a tread rubber, while retaining two cord-arrayed layers positioned on a radially inner side of the tire. Then, at least one cord-arrayed layer and a fresh tread rubber are bonded onto the base tire to form a built tire, applying an internal pressure into the built tire, and the built tire is vulcanized and shaped inside a mold, wherein a diameter (Bo) of the radially outermost cord- arrayed layer of the built tire before application of the internal pressure and a diameter (B) of the radially out- most cord-arrayed layer on the vulcanization and shaping inside the mold satisfy the following inequations: O ? (B - Bo)/B X 100 ? 0.76.
