ABSTRACT:
This disclosure relates to an improvement in the "wide stance" method of manufacturing a pneumatic tire. In this method the space between the two annular wire bead bundles of the tire is substantially greater than the space between the beads in their operable condition, mounted on the recommended rim. The improvement comprises the steps of locating the bead areas of the uncured tire which contain the annular wire bead bundles in annular cavities in the tire mold which are adapted to receive the bead areas. This maintains the wire bead bundles in their proper location during the entire curing operation.
