A sealing preparation for tire problems is proposed which seals 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 devices are proposed for introducing the sealing preparation into the tire
and for the pumping up. An air compressor, or liquefied dinitrogenoxide, or sulphur
hexafluoride are preferably used with these devices as a pressure source.
