Abstract: The present invention relates to a tire having a tread of lug and groove configuration of a black-colored, carbon black reinforced rubber composition, wherein at least a portion of the visible surface of at least one of said grooves, exclusive of the outer surface portion of said carbon black reinforced rubber lugs intended to be ground-contacting, is of a non-black colored, synthetic amorphous silica reinforced rubber composition exclusive of carbon black.

Abstract: A tire having at least one crescent-shaped rubber composition as an insert in its sidewall region which is comprised of at least one diene-based elastomer, carbon black and, optionally, silica and at least one of dithiodipropionic acid, benzoic acid and salicylic acid.

Abstract: The invention relates to a rubber composition containing relatively low levels of carbon black and/or silica reinforcement together with a particulate calcium carbonate and selected modifiers. The invention particularly relates to a tire having a component, particularly a tread, of such composition.

Abstract: Hoses are often reinforced with fabric to improve their performance characteristics, such as burst strength. For instance, radiator hose used in automotive applications is generally reinforced with continuous yarn. However, it is a labor-intensive process to manufacture such hoses which include fiber reinforcements. A substantial amount of material waste also generally occurs in the manufacture of such fiber-reinforced hose. By utilizing the technique of this invention, hose which has a high level of burst strength can be manufactured without including continuous yarn reinforcement.

Abstract: The present invention relates to a rubber composition containing substantial silica reinforcement and pneumatic tires having treads comprised of such rubber composition. The rubber composition comprises an elastomer, substantial silica reinforcement, optionally a minor amount of carbon black reinforcement, and a triblock copolymer of terminal hard styrene based segments and of internal diene based elastomer segments.
