An aircraft tire having at least 6 pairs of bias carcass plies and three bead cores in each bead portion is disclosed. Each bead core is specifically designed to maximize the tires durability wherein the bead heel core has at least one more row or column of bead wires when compared to the middle bead core.

Molds for injection molding tire components have controlled temperature passages leading to a manifold surrounding each mold cavity. The manifold is positioned to minimize weld lines in the injected tire component. In addition, a narrow gate opening between the manifold and mold cavity provides an elevated temperature of the injected material for decreasing the curing time of the tire component in the mold. Blade members may support and position tire components such as bead apex assemblies in the mold. These tire components may be unloaded by an unloader ring in communication with a source of vacuum for pulling the tire component out of the mold.
