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.

Preparation for sealing punctured tires and apparatus for the sealing and pumping up of tires

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.

A pneumatic vehicle tire comprising a tread strip which forms the tire tread and is made from an electrically insulating or poorly conducting material and comprising, beneath the tread strip, a layer which is a good electrical conductor wherein, in order to bring about an adequate dissipation of electrical charge from the vehicle bodywork, the layer which is of good electrical conductivity extends at least regionally up to and into the tire running surface when considered over the circumference of the tire.
