1. A toroidal tire is provided containing at least one component comprised of a carbon black reinforced polyurethane containing a dispersion of molecular sieve desiccant and from about 1 to about 5 weight percent of granules of pulverized pellets of compacted rubber reinforcing carbon black where said granules have an average aggregate particle size in a range of from about 1 to about 15 microns,
wherein the polyurethane is the product of a reaction mixture of at least one polymeric polyol and organic polyisocyanate having a ratio of isocyanate groups to hydroxyl groups of said polymeric polyol in a range of from about 1.1/1 to about 2/1, wherein said polymeric polyol is comprised of at least one of polyester polyol and polyether polyol, wherein the carbon black reinforcement of said polyurethane is the product of said polyisocyanate and isocyanate reactive groups on said pulverized rubber reinforcing carbon black granules were said isocynate reactive groups are comprised of at least one of hydroxyl groups, carboxylic acid groups, and quinone groups.
