Method of forming non-pneumatic tire including pressure application between an intermediate section and an outer shear band ring

A method of forming a non-pneumatic tire comprising the steps of:

• providing an outer shear band ring, wherein the outer shear band ring has an inner diameter;
• providing an intermediate section that has a supporting structure that has spokes comprising a thermoplastic elastomer, wherein the intermediate section is in an uncompressed state, wherein in the uncompressed state the intermediate section has an outer diameter, wherein the outer diameter of the intermediate section in the uncompressed state is greater than the inner diameter of the outer shear band ring;
• compressing the intermediate section from the uncompressed state to a compressed state;
• inserting the intermediate section when in the compressed state inside of the outer shear band ring;
• and
• releasing compression of the intermediate section when the intermediate section is inside of the outer shear band ring such that the intermediate section moves from the compressed state to a state of interference fit with the outer shear band ring;
• wherein the supporting structure has an inner V pair spoke section and an interface ring, wherein the interface ring is located outward from the inner V pair spoke section in the radial direction, wherein the supporting structure has an outer V pair spoke section located outward from the interface ring in the radial direction;
• wherein the state of interference fit of the intermediate section causes the application of pressure of from 1-2 bar onto an inner surface of the outer shear band ring 360 degrees around an axis of the outer shear band ring;
• providing a hub;
• and
• positioning the hub inside of the intermediate section such that the intermediate section is located outward from the hub in the radial direction, wherein the positioning of the hub step is performed after the step of releasing compression of the intermediate section.
