Abstract: A pneumatic tire having a rubber component where the rubber in said component is comprised of (A) from 1 to 25 weight percent of high impact polystyrene; and (B) from 75 to 99 weight percent of a rubber containing olefinic unsaturation.

Abstract: There is disclosed a rubber composition comprising: (A) 100 parts by weight of at least one rubber containing olefinic unsaturation; and (B) 1.5 to 50 phr of a cyclodextrin compound.

Abstract: The invention relates to the preparation of a silica reinforced rubber composition where alkoxysilane and/or sulfur cure reactions within the elastomer host are controlled by the use of a selected amino acid, or amino acid-containing protein based, activator. The invention also relates to such composite and to a tire having at least one component of such composite.

Abstract: This invention relates to the preparation of an elastomer which contains a dispersion of a reinforcing system formed in situ within an elastomer host by the interaction of a telechelic hydroxy and/or alkoxy terminated polysiloxane and a reticulating agent having a moiety comprised of at least two alkoxy groups. The invention further includes a rubber composition of at least two elastomers wherein one of said elastomers is a pre-formed composite of elastomer and the in situ formed reinforcement system. A tire having a component of such rubber composition, particularly a tire tread, is specifically contemplated.
