A method of assembling spokes into a non-pneumatic tire (10) is provided in which a shear band (16) is located outward from a hub (12) in a radial direction. A segment (20) is present that has a plurality of spokes (22), and both inner and outer radial bonding ends (24, 26). The plurality of spokes (22) engage both of these bonding ends (24, 26). The outer radial bonding end (24) is attached to the shear band (16) using adhesive (28), and the inner radial bonding end (26) is attached to the hub (12) using adhesive (28). This segment (20) extends less than 360 degrees about the central axis (14) in a circumferential direction.

A support structure for a non-pneumatic tire and a tire incorporating such support structure. A continuous membrane extends between a radially-inner leg and a radially-outer leg. Joints and reinforcement may be provided on sides of the membrane. An annular band may be connected with the radially-outer leg. A wheel, hub, or other structure may be connected with the radially-inner leg.
