This invention relates to provision of heat conductivity for a tire containing a polyurethane component with a dispersion of layered hexagonally crystalline boron nitride (h-BN) particles. The invention particularly relates to a pneumatic rubber tire with a polyurethane component wherein a path of thermal conductivity is provided from the interior of the tire to an exterior surface of the tire for dissipation of the conducted heat to the atmosphere. The polyurethane is the product of a castable liquid polyurethane reaction mixture without containing carbon-to-carbon double bonds as distinguished from millable, sulfur curable, polyurethanes. It may sometimes be referred to as being a cast polyurethane.
