Abstract: A cordless vehicle tire of an elastomeric polyurethane sidewall adhered to a tread of an elastomeric ethylene/propylene/non-conjugated diene polymer wherein the polyurethane is the product of reacting an organic diisocyanate with a poly(alkylene oxide) glycol to prepare an isocyanato-terminated prepolymer cured by reaction with methylene dianiline introduced into the prepolymer in the form of a complex with salts of the group sodium chloride, sodium bromide, sodium iodide, sodium nitrite, lithium chloride, lithium bromide, lithium iodide, lithium nitrite or sodium cyanide, said methylene dianiline being liberated from said complex by heating the mixture of prepolymer containing complex, and a process for producing such tires.
