Various example embodiments of a non-pneumatic tire, and methods for making the same, are disclosed. In one embodiment, a non-pneumatic tire is provided, the non-pneumatic tire comprising: a tread; at least one support ring, wherein the at least one support ring and the tread are concentric; at least one base element oriented between the tread and the at least one support ring; and a hub.

In a non-pneumatic tire, an outer ring comprises a laminate having a plurality of fiber layers, and at least one elastomer layer interposed between an adjacent pair of a plurality of fiber layers, the plurality of fiber layers include an outermost layer which among the plurality of fibers is that which is arranged in outwardmost fashion in a tire radial direction, and an innermost layer which among the plurality of fibers is that which is arranged in inwardmost fashion in the tire radial direction, and at least one of the outermost layer and the innermost layer contains a first fiber array at which fibrous material is arrayed so as to extend in the long direction of a joint.

Various example embodiments of a non-pneumatic tires are presented. In one embodiment, a non-pneumatic tire is provided, comprising: a tread; a support ring comprising a plurality of support ring elements, each having the same diameter, wherein the plurality of support ring elements are coupled to one another by at least one strap; a hub, wherein the tread, the support ring, and the hub are concentric; a plurality of base elements oriented between the tread and the support ring, wherein each of the base elements extends along the width of one of the support ring elements. Alternatively, each of the base elements may extend from an axially outer edge of a support ring element to the center of an adjacent support ring element.

An apparatus for assembling a non-pneumatic tire that includes a base and a plurality of elements that move relative to the base. The plurality of elements have a central axis, and the elements are disposed in a circumferential direction around the central axis and move in a radial direction towards and away from the central axis. A radial movement member, hub, and a plurality of spokes are also present. Each one of the spokes is disposed between adjacent ones of the elements. The elements and the spokes are moved inwards in the radial direction by the radial movement member towards the central axis so that the spokes are moved in the radial direction towards the hub. Adhesive engages the spokes and the hub at an attachment location of the spokes and the hub.

A non-pneumatic tire includes a tread; a shear band, and a connecting web positioned between a hub and the shear band. The shear band has a first and second membrane layer formed of a plurality of parallel reinforcement cords arranged at an angle of 10 degrees or less with respect to the tire equatorial plane, said o tread further comprises a first angled belt located radially outward of the second membrane layer, and a second angled belt located radially outward of the first angled belt, wherein the first and second angled belt each have parallel reinforcement cords having a belt angle in the range of 15-30 degrees with respect to the tire equatorial plane, and wherein the angle of the second angled belt has an angle equal and opposite direction of the belt angle of the first angled belt.

A non-pneumatic tire includes a shear band having a first membrane layer located radially inward of the outer annular tread, a second membrane layer located radially outward of the first membrane layer, wherein the first and second membrane layer are formed of a plurality of parallel reinforcement cords arranged at an angle of 10 degrees or less with respect to the tire equatorial plane, said outer annular tread further comprises a first angled belt located radially outward of the second membrane layer, and a second angled belt located radially outward of the first angled belt, wherein the first and second angled belt each have parallel reinforcement cords having a belt angle in the range of 15-30 degrees with respect to the tire equatorial plane, and wherein the angle of the second angled belt has an angle equal and opposite direction of the belt angle of the first angled belt.

A tyre comprising an adaptive tread, the adaptive tread comprising a plurality of surface sections, wherein each surface section can move without deformation relative to the other surface sections to form a tread pattern.

A composite PDU tire in an aircraft cargo handling system may comprise a plurality of bonded regions configured to propel cargo within an aircraft cargo bay. The composite tire may include edge regions that are stiffer than a cylindrical region. The edge regions may be configured to have a greater wear resistance and abrasion resistance relative to the cylindrical region. The cylindrical region may be configured to have greater traction relative to the edge regions. The edge regions may include a fillet profile and may be configured to reduce chipping as cargo climbs across the tire.
