Pneumatic tires are efficient at carrying loads, because all of the tire structure is involved in carrying the load. Pneumatic tires are also desirable because they have low contact pressure, resulting in lower wear on roads due to the distribution of the load of the vehicle. Pneumatic tires also have low stiffness, which ensures a comfortable ride in a vehicle. The primary drawback to a pneumatic tire is that it requires compressed fluid.

An apparatus for assembling a non-pneumatic tire is provided that includes a plurality of spokes attached to a hub, a frame, and a plurality of mechanical elements disposed between and engaging successive spokes. The spokes extend to locations radially inward and radially outward of the locations of engagement with the mechanical elements. A radial movement member moves the mechanical elements in a radial direction. The spokes are compressed by the mechanical elements, and retaining elements engage the mechanical elements to hold them and the spokes in this position. Release by the retaining elements and outward radial movement of the mechanical elements urge the spokes toward a shear band that is outward in the radial direction. Adhesive located between the spokes and the shear band is pressed there between through this urging to result in the spokes being attached to the shear band in a state of pre-compression.
