A method of forming a non-pneumatic tire is provided that includes the steps of providing an outer shear band ring (12) that has an inner diameter. An intermediate section (14) is provided that has a supporting structure. An outer diameter (102) of the intermediate section (14) in the uncompressed state is greater than the inner diameter (70) of the outer shear band ring (12). The intermediate section is compressed from the uncompressed state to a compressed state, and is inserted inside of the outer shear band ring (12). Compression of the intermediate section is released when the intermediate section is inside of the outer shear band ring, and the intermediate section (14) moves from the compressed state to a state of interference fit with the outer shear band ring (12).
