Zusammenfassung:	The present application relates to a rubber composition containing a precipitated silica filler having first and second aggregates. The first aggregates are from 10 to 90 weight percent of the overall weight of the silica having first and second aggregates. The second aggregates range from 90 to 10 weight percent of the overall weight of the silica having first and second aggregates. The first aggregates consist essentially of particles ranging in size of from 5 to 15 nanometers in diameter. The second aggregates consist essentially of particles ranging in size of from 17 to 30 nanometers in diameter. The pore size distribution of the silica, as measured by mercury porosimetry is monomodal.
