    Abstract: A vulcanized elastomeric composition of matter comprises the reaction product of a sulfur-containing reagent with an anionic living polymer, the reagent being selected from the group consisting of R3—Si—S—R′—X, where R can all be the same or different and is selected from the group consisting of alkyls having from 1 to 8 carbon atoms, cycloalkyls having from 3 to 11 carbon atoms, or an arylene having from 6 to 14 carbon atoms, and X is a halogen, to form a R3—Si—S—R′ ended polymer; a filler; processing oil; and a cure package containing a deprotecting agent and at least one sulfur cure accelerator. A method for making a vulcanized elastomeric composition of matter comprises terminating a living anionic polymer with a sulfur-containing reagent selected from the group consisting of R3—Si—S—R′—X, where R can all be the same or different and is selected from the group consisting of alkyls having from 1 to 8 carbon atoms, cycloalkyls having from 3 to 11 carbon atoms, or aryls having from 6 to 14 carbon atoms, R′ is an alkylene having from 1 to 8 carbon atoms, a cycloalkylene having from 3 to 11 carbon atoms, or an arylene having from 6 to 14 carbon atoms, and X is a halogen, to form a R3—Si—S—R′ polymer having a protected mercapto group; deprotecting the mercapto group prior to or during vulcanization of the composition, and attaching the mercapto group to a polymer backbone of one of the polymers. A method is also provided for reducing hysteresis and the invention provides improved pneumatic tires.

    Abstract: A method of developing a set of input forces used to analyze tire wear includes the steps of characterizing a wear course by driving a vehicle over the wear course and measuring data related to a plurality of forces experienced by the vehicle. A vehicle characterization model for a target vehicle having at least one tire is developed. The vehicle characterization model is used to calculate force data that represents the forces that would be experienced by at least one tire of the characterized vehicle if the characterized vehicle were driven over the characterized wear test course in the first vehicle configuration. The force data is then used to analyze tire wear using a computer prediction technique or by running an indoor wear test on the tire.

    Abstract: A polar surfactant, preferably organic, is disclosed to increase dispersion of reinforcing filler aggregates in rubber compositions. The surfactant acts on binders present in the reinforcing filler aggregates so that the surfactant associates with the water soluble binder on carbon black to increase carbon black dispersion. The polar surfactant has an hydrophilic-lipophilic balance value of about 3 to about 35. Rubber products using the composition and methods of making the composition are also disclosed.
