ABSTRACT:
In a tire inflation insert of the present invention, a tire casing contains a ring having a plurality of air filled spaces or pockets. The tire inflation insert comprises a roll of a flexible sheet, wrapped with a securing belt of material such as tape, which is formed into a ring for insertion into the tire casing. The flexible sheet comprises rubber or plastic sheeting or other flexible material having a plurality of air pockets therein although flexible foam material may also be used. In some cases non-resilient foam may be introduced into the tire casing in the form of a liquid mixture which chemically reacts to form a non-resilient foam and fills the entire cavity thereof. Such non-resilient foam is currently used in packaging materials where chemicals are mixed as they are introduced to the cavity and the chemical reaction causes foam to form within the cavity forcing air out of any cavity and completely filling the same with foam having a plurality of cavities. In addition, a flexible sheet similar to that used to protect products during shipping may be used or other matting which is formed by the process of pressing two sheets of rubber, plastic or other flexible material together using heat and forced air to form one sheet of a flexible sheet containing compressed air bubbles. Any suitable process for creating a flexible sheet, however, can be used.
