Patent ID: 6944948

Claim:
A method of lubricating an interface zone between a safety support and a tire mounted as an assembly comprising the following steps: a) providing the tire, the safety support and a wheel rim, b) mounting the tire on the wheel rim having the safety support disposed against the rim and inside a cavity of the tire, c) providing a reservoir within a cavity of said safety support of lubricant in fluid communication with said interface zone via a lubrication port, d) closing said reservoir by a removable seal, e) providing a quantity of lubricant in said reservoir, f) placing said removable seal against said lubrication port, such that said port remains closed and the lubricant remains in said reservoir when the mounted assembly is rolling while the tire is inflated, g) establishing a non-transient contact between the inside surface of the tire and said seal when the mounted assembly is in the flat rolling condition, and h) removing said seal by said non-transient contact between the inside surface of the tire and said seal, and whereby removing said seal requires a substantially simultaneous condition of a temperature increase in the tire cavity and of a mechanical contact between said seal and the inside portion of the tire, whereby said method allows lubricant to be dispensed in said interface zone only when the mounted assembly is in the flat rolling condition.
