ABSTRACT:
A raw pneumatic tire carcass having an uncured, elastomeric, annular body and an uncured, elastomeric, liner superposed upon and affixed to the internal surface of the body, is disclosed. The liner in one form thereof includes bead-communicating recesses for venting fluid from between the liner and an inflatable bladder used in a mold for effecting inflation of the body and liner from a cylinder to a torus. The liner in the latter form is constituted of an appropriate thermoplastic material which, when engaged and inflated by a smooth surface of the bladder and vulcanized, undergoes a transformation in which the recesses gradually disappear substantially and are transformed into a correspondingly smooth surface. A second form of the liner (which is preferably incorporated as part of the first said form of the liner) is represented by a convexity on at least one surface of the liner. The convexity serves to prevent an excessive reduction in thickness that the liner otherwise undergoes in the crown region thereof when inflated from a cylinder to a torus.
