Abstract: This invention relates to a vehicular tire containing at least one carbon black reinforced polyurethane component.

Abstract: The invention relates to a rubber composition and its preparation having a crosslink distribution, particularly at least two types of crosslinks, its preparation, and an article of manufacture, including a tire, having a component of such rubber composition. In one embodiment the crosslink distribution can be a controlled crosslink distribution of at least two types of crosslinks. In one embodiment, such crosslink distribution relates to an inclusion in the rubber composition of an additive to promote the crosslink distribution where the additive itself has a part of the desired crosslink characteristics. The distributed crosslinks can be of different types including different length, different chemistry, and connecting different points on the crosslinked rubber chains. The distributed crosslinks can be present in different concentrations in the rubber composition. The crosslink distribution can be random or in the nature of a gradient change between domains of different crosslinks.

Abstract: The present invention is directed to a rubber composition comprising a diene based elastomer comprising a functional group selected from the group consisting of hydroxyl, primary amine, and secondary amine; and a binding agent selected from the group consisting of water-dispersible resin, polyelectrolytes, and polypeptides. The invention is further directed to a pneumatic tire including the rubber composition, and a method of increasing the green strength in a rubber composition.
