Abstract of the Disclosure A pneumatic tire is made using flat ribbon wire in the belts and a tacky puncture sealant positioned between the belts and the air chamber. The broad sides of the ribbon wire is perpendicular to the tire radius. The combination of the ribbon wire and the puncture sealant prevents air from leaking out of the tire when a nail punctures the tire and also seals the tire in most instances, when the nail is pulled out of the tire.
