The present invention provides a non-pneumatic structural bicycle tire, manufactured from TPU, TPE, other thermoplastics including TPS and TPZs, or other polymers and additives, as well as similar or dissimilar plastic such as PLA, ABS, and or recycled plastic material blend. The tire includes structural members of various sizes, thicknesses and angles, both contouring with the wheel, forming both arches, bridges and angled, voids including Euclidian and non-Euclidian triangles, diamonds, “V” shapes and other voids either with or without similar or dissimilar plastic infill between members in various fill levels and designs. The structural members create cross members and supports for transverse protrusions which compress to varying degrees depending on their specific characteristics. The non-pneumatic structural bicycle tire provides increased comfort, weight reduction, and durability when compared to other pneumatic or non-pneumatic tires.

The present invention provides an annular beam of monolithic construction of one homogeneous material and a related efficient, low-cost non-pneumatic tire. Specific geometric design, combined with nonlinear elastomer physical properties, enable the suppression of all reinforcing belts, continuous fibers, or other strengthening layers in the annular beam. The annular beam consists of at least two bands that are continuous in the circumferential direction and connected by a web geometry. The non-pneumatic tire consists of the annular beam, a ground contacting portion, a central wheel, and a plurality of web spokes that connect the wheel and beam. When the tire is loaded to a design load against a flat surface over a design contact length, a contact area of essentially uniform pressure is produced, while the load is transmitted from the beam to the hub via tension in the web spokes. The tire can be economically manufactured.

The invention described tires resisting temperature over 180 degrees Fahrenheit, using both pneumatic and non-pneumatic properties in conjunction to support the integrity of the tire on pneumatic rims where the tire's main sections are the two beads, the air pocket, the elastomeric flection design, shear band, and the tread. A premium tire assembly comprising of elastomeric and flexible properties, which supports the pneumatic air pocket and is reasonably secured onto the rim with circularly radial beads. The said tire uses elastic and flexible properties to support the load of the vehicle instead of using pneumatic properties alone. All of the sections are joined by a framework. The elastomeric flection and pneumatic air pocket combination technology alone makes Hybrid Tires unique and revolutionary.

An assembly (1) for a tire comprises a first structure (10), a second structure (12) and bearing cord elements. The assembly comprises a gimped securing element (18) comprising a core (18a) around which a gimp yarn (18b) is wound. The core (18a) exhibits an elongation at rupture A.sub.rupture_core and the gimp yarn (18b) exhibits an elongation at rupture A.sub.rupture_gimp such that: A.sub.rupture_core<A.sub.1=h/(E+e.sub.1+e.sub.2) and A.sub.rupture_gimp>A.sub.1=h/(E+e.sub.1+e.sub.2) in which h is the conformation height of the assembly, e.sub.1 is the thickness of the first structure (10), e.sub.2 is the thickness of the second structure (12), and E is the lock length.

A rolling element such as a wheel and wheel attachment or caterpillar type rolling element for improving support. A rolling element includes: a first support surface formed as a loop configured to roll on a substrate such that a region of the first support surface alternately contacts and separates from the substrate, a first extension running about the loop and disposed about the first support surface, wherein where the rolling element is disposed on the substrate and a load is applied thereto: in a first region of the loop where the first support surface is separate from the substrate the first extension extends beyond the first support surface, and in a second region of the loop where the first support surface contacts the substrate the first extension is deformed so as to form a second support surface which contacts the substrate.

A method of making a tire includes placing substantially circular sheets of polymeric material on top of each other until a tire is built to a predetermined width. A predetermined tread shape is formed along a circumference of the substantially circular sheets of polymeric material.

Specific geometric design, combined with nonlinear elastomer physical properties, enable the suppression of all reinforcing belts, continuous fibers, or other strengthening layers in the annular beam.

A tire assembly includes an assemblage formed of first and second impregnated woven or knitted structures, a bearing structure, and at least one sacrificial holder. The first impregnated woven or knitted structure includes a first woven or knitted fabric and a first layer of a first polymeric composition. The second impregnated woven or knitted structure includes a second woven or knitted fabric and a second layer of a second polymeric composition. The bearing structure includes bearing elements connecting the first and second woven or knitted fabrics together. Each sacrificial holder is structured to hold temporarily the first and second impregnated structures in contact with each other, connecting the first and second woven or knitted fabrics together. When the first and second impregnated woven or knitted structures are separated from each other, each sacrificial holder breaks before any breakage of the bearing elements.

The present disclosure relates to multi-core semi-pneumatic tires and methods for manufacturing the same. In one exemplary embodiment, a semi-pneumatic tire includes an outer surface configured to contact ground; an inner surface configured to contact a wheel; and a plurality of hollow cores formed between the inner and outer surfaces in the semi-pneumatic tire, wherein each hollow core extends around a circumference of the tire.
