    Abstract: The present invention is directed to a method for producing a cured tire filling composition and the composition resulting from such a method. The A component has from about 3 to about 30 weight % of a polyisocyanate comprising polymeric toluene diisocyanate (TDI) or diphenylmethane diisocyanate (MDI) with an average functionality of 2 or greater, from about 10 to about 60 weight % of a high molecular weight polyol or blend of polyols having a hydroxyl number in the range of about 20 to about 56, and the balance of a plasticizer. The amount of plasticizer is an amount sufficient to lower the NCO content of the resulting. A component to be less than 10% and is in the range of from about 10 to about 80 weight %. The B component has from 0 to about 30 weight % of the high molecular weight polyol or blend of polyols, from about 70 to about 99 weight % added water, from about 1 to about 8 weight % of a hydrophilic moiety, and from about 0.1 to about 5 weight % of a catalyst.
