Abstract
A tire is provided having a component comprised of a rubber composition containing at least one conjugated diene-based elastomer and a combination of rubber reinforcing fillers composed of rubber reinforcing carbon black, precipitated silica and granular functionalized mineral comprised of at least one of aluminum hydrate (ALOOH) and titanium dioxide. The granular mineral is functionalized by pretreatment with a coupling agent. The granular mineral fillers are pretreated with a coupling agent to promote a combination of rubber reinforcing effect for the mineral fillers and to promote a hydrophobation of the mineral fillers to promote their dispersability in the rubber composition.
