ABSTRACT:
A pneumatic tire having a casing which defines in part an internal annular inflation chamber is provided with a small amount of low density, discrete, cellular, resilient, polymeric fibers within the inflation chamber to provide a reduction in the rate of inflation loss from the chamber upon puncture. Each fiber has many closed cells filled with gas and the polymer portion of each fiber is substantially all present as thin, filmy cellular walls. The fibers may be of varying length and may be added to the inflation chamber before or after tire is mounted on its rim.
