Claims10
A method of assembling a vehicle wheel comprising:
- placing at least one piece of precured and foamed elastomeric material inside a cavity of a cured tire;
- mounting the tire with the at least one piece of precured and foamed elastomeric material on a wheel rim to form a closed cavity with the wheel rim;
- filling space in the closed cavity around the at least one piece of precured and foamed elastomeric material with liquids forming a polyurethane;
- and
- reacting the liquids in the closed cavity to form polyurethane without applying additional heat to the tire,
- wherein the at least one piece of precured and foamed elastomeric material comprises strips of precured and foamed elastomeric material positionable inside the cavity in a circumferential direction about a tire centerline, discs of precured and foamed elastomeric material positionable inside the cavity in a direction generally perpendicular to the tire centerline, circumferential segments of precured and foamed elastomeric material, or particles of precured and foamed elastomeric material or a combination thereof.
