Abstract
This invention relates to a pneumatic tire with puncture sealing properties and a method for manufacturing such a tire. In this method of manufacturing such a self-sealing pneumatic rubber tire a polymer composition layer is built into the tire in a relatively conventional manner. Under the conditions of heat and pressure used to cure the tire this polymer composition is both crosslinked and depolymerized to form a tacky material which has puncture sealant properties (the sealant layer). Ordinary tire manufacturing techniques can be employed since the sealant layer has the physical properties of ordinary butyl rubber used in tire building at the time it is assembled into the tire.
