Abstract: A mold for forming a tire curing bladder. The mold has an outer mold assembly enclosing an inner mold core assembly. The outer mold comprises three sections and the inner mold comprises two portions. The outer mold and the inner mold core form a mold cavity therebetween. In one embodiment, the mold cavity defines a frog eye geometry where a cylindrical space is formed having a diameter that is greater for portions of the cylindrical spaced away from a centerline of the mold cavity than for portions near the centerline.

Abstract: A tire forming bladder composed of an elastomeric membrane constructed and shaped for curing low aspect ratio tires. The bladder includes clamping feet to enable it to be clamped onto a post for insertion into a tire curing mold. The bladder has a cross-sectional profile where the distance between the clamping feet is less than the distance between the shoulder areas of the bladder. In addition, the shoulder areas of the bladder are of a thinner gauge than the remainder of the bladder membrane and accordingly expands a greater amount than the rest of the bladder membrane when pressurized.

Abstract: A method of making a non-pneumatic tire comprising a toroidal-shaped tube having inner and outer circumferential surfaces and opposite side surfaces collectively forming a hollow chamber therebetween, the tube having at least two openings proximate the inner circumferential surface, and a solid fill composition disposed in the hollow chamber of the tube. The non-pneumatic tire provides the benefits of a smooth, comfortable ride, durability, and lightweight with good load-carrying capability.
