Abstract
The invention relates to a tire having at least one component comprised of a rubber composition which contains pre-hydrophobated precipitated silica aggregates. Such tire component may be, for example although not limited to, a tire tread, sidewalls and/or sidewall insert. Such pre-hydrophobated precipitated silica aggregates are contemplated as being prepared, for example, by treatment of a colloidal silica with a combination of both an organomercaptosilane and an alkylsilane.
