<p>Cured tread rubber compositions of tires contain cured organic rubber, from 40 to 150 phr of reinforcing carbon black, and reinforcing reinforced amorphous precipitated silica wherein the silica has a surface area of from 160 to 340 m2/g and a pore diameter at the maximum of the volume pore size distribution function of from 5 to 19 nm. The presence of such reinforcing silica provides improved tire performance characteristics, especially improved paved highway performance, to tires having treads of the cured tread rubber compositions.</p> |
