Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A pneumatic tire and wheel assembly capable of being run in a deflated condition comprising: (a) a tire having a tread area and a pair of sidewalls defining an interior surface, and a wheel upon which the tire is mounted to define therewith an inflation chamber, said wheel having a rim with a pair of opposed annular flanges and a saddle, located between the rim flanges, extending into a radially outwardly position on the rim base, and (b) a completely closed rupturable enclosing means, containing lubricating material for the interior surface of the tire, mounted on the saddle and located between the saddle and the interior surface of the tire so as to be trapped between the saddle and the interior surface of the tire and thereby ruptured to release the lubricating material when the assembly is run deflated.
Claim 2
Dependent Claim
139 words
A pneumatic tire and wheel assembly capable of being run in a deflated condition comprising: (a) a tire having a tread area and a pair of sidewalls defining an interior surface, and a wheel upon which the tire is mounted to define therewith an inflation chamber, said wheel having a rim with a pair of opposed annular flanges and a saddle, located between the rim flanges, extending into a radially outwardly position on the rim base, and (b) a completely closed rupturable enclosing means, containing lubricating material for the interior surface of the tire, mounted on the saddle and located between the saddle and the interior surface of the tire so as to be trapped between the saddle and the interior surface of the tire and thereby ruptured to release the lubricating material when the assembly is run deflated.
Claim 3
Dependent Claim
148 words
A pneumatic tire and wheel assembly capable of being run in a deflated condition comprising: a tire having a tread area and a pair of sidewalls defining an interior surface; a wheel upon which the tire is mounted to define therewith an inflation chamber, said wheel having a rim with a base and a pair of opposed annular flanges; a saddle positioned between the flanges and extending radially outwardly from the rim base; and a completely closed enclosing means, separate from the interior surface of the tire and the saddle and containing lubricating material for the interior surface of the tire, mounted on the radially outermost portion of the saddle which faces the interior of the tire tread region so as to be trapped between the saddle and the interior surface of the tire and thereby ruptured to release the lubricating material when the assembly is run deflated.
