<p>A rubber composition based on at least a diene elastomer, a reinforcing filler and a crosslinking system, characterized in that it comprises at least 10 to 150 phr of a platy filler and from 0.01 to 0.3 phr of a metal salt. This composition has good processing and mechanical properties, and also improved oxygen impermeability properties over a wide temperature range, from ambient temperatures when the tire is stationary up to the temperatures of the tire when it is running. According to one preferred embodiment, the rubber composition described above can be used in the tire as a protective elastomer layer in at least one part of the tire.</p> |
