Making a tire mold having a plurality of complete tire mold segments ( ) of epoxy resin mold material formed in the chambers ( ) of segmental shoes ( ) and having reinforced stand alone ribs ( ) formed in recesses in the tread models mounted in the shoes. The shoes ( ) and models ( ) are reusable and have standard shoe split diameters and chord lengths to reduce the time necessary to make the molds. The models ( ) are of resilient material and are also reusable.

Tire mold reinforcement

A non-pneumatic tire having an elastomeric portion encompassing the tread and a radially inward foam portion. In the elastomeric portion, certain physical characteristics of the elastomeric portion differ between the tread surface and the radially inward region. An increase in the Shore A hardness provides the tire structure with an elastomeric hoop which imparts improved rolling resistance to the tire, without compromising wet/dry traction. Likewise, the weight and compliance of the tire may be adjusted in the foam portion without adverse effects on the rolling resistance. The non-pneumatic tire may be formed from a multi-shot process in a spin cast procedure.

A tire assembly comprising outer and inner tires having at least one vent and one plug is described. The vents and plugs mate in the assembly providing an air tight seal in the bead seal region of the tires. The vents or plugs permit air to escape from the outer tire if an attempt is made to mount the outer tire on a rim without a mating inner tire.

A device (20) for retaining the beads of a tire against the flanges of a rim. The bead retainer device (20) is capable of being manufally deformable in the axial direction. The bead retainer device is also capable of being manually deformable in the circumferential direction such as to be collapsible.

The tread reinforcing belt structure (24) of a pneumatic tire (10) has at least one belt ply (29) of flat steel wire. The belt ply of flat steel wire is stiffened by other components of the tread reinforcing structure such as belt plies of steel cables (28,30). It is especially important that the axially outermost edge portions of the belt ply of flat steel wires be supported by other components of the tread reinforcing belt structure, and that the flat wire have specific cross-sectional dimensions.
