Abstract
This invention relates to a conjugated diene-based rubber composition reinforced with silica-based reinforcement together with a non-silane coupling agent as a combination of 1-thioglycerol(3-mercapto-1,2-propanediol) and 2,2′-benzothiazyl disulfide. Said coupling agent materials may be provided for mixing with said diene-based rubber(s), for example, as individual materials, as at least one of said materials being supported on a carbon black carrier or as being pre-reacted, or otherwise pre-treated, with synthetic silica aggregates. The invention includes an article of manufacture, including a tire, having at least one component comprised of such rubber composition.
