Abstract:
1. 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.
