Abstract

A tire puncture sealing preparation is directed to sealing in wet conditions, at low and high temperatures and with defects at the transition between the tread and the side wall of the tire. The sealing preparation contains natural rubber latex or a combination of rubber latex and compatible adhesive resin. Furthermore, various embodiments are directed to introducing the sealing preparation into the tire and for the pumping up thereof. An air compressor, or liquefied dinitrogenoxide, or sulphur hexafluoride are preferably used as a pressure source with these devices.
