Abstract
A tire (10) produced via a molding or casting process in a manner such that each of its bead areas (16) includes an annular slot (42) whereby the slots permit the insertion of an inextensible annular reinforcement element (40) into each of the bead area slots (42) after the molding or casting process. Slots (42) are preferably produced by the addition of annular collars (64) to either the outer member (50) or core member (60) of an improved molding or casting die (48). The improved molding or casting process includes a step of forming a circumferential slot (42) in each tire bead area (16), with these slots (42) permitting the addition of an inextensible annular reinforcement element (40) into each bead area (16) after the molding or casting process.
