A method for manufacturing a modified silica product includes admixing a mercapto silane and a silica to form a hydrophobated silica, and treating the hydrophobated silica with an oxidizing agent. Likewise, a method for manufacturing a silica masterbatch with the modified silica product includes the admixing a mercapto silane solution and a silica slurry to form a hydrophobated silica slurry, and then treating the hydrophobated silica slurry with an oxidizing agent to form a modified silica slurry. The modified silica slurry is blended with a rubber latex, which is then coagulated to form the silica masterbatch. Rubber formulations and articles manufactured with one of the modified silica product and the silica masterbatch are also disclosed.
