The invention relates to a rubber mixture, in particular for vehicle air-inflated tires, seat belts, belts and hoses. The rubber mixture is characterized by the following composition:

Rubber mixture comprising environmentally friendly softeners

A pneumatic vehicle tire which is provided with a belt and with tread rib sections which are separated from one another by respective circumferential grooves. One or more cord fabric plies are disposed in the vicinity of the circumferential grooves to reinforce the belt. The cord fabric plies essentially extend over the width of the groove, and preferably have a width which is slightly greater than the width of the grooves.

Pneumatic vehicle tire

A filling gas for a tire having one or more hollow chambers, especially vehicle tires with a body of rubber or rubber-like material having suitable reinforcement inserts. Sulfur hexafluoride (SF.sub.6) is used as the filling gas, which can also be a mixture of sulfur hexafluoride and one or more other gases, such as air. The tire hollow chamber, in comparison to the air, contains a greater quantity of sulfur hexafluoride. The ratio of air quantity to the quantity of sulfur hexafluoride is in the range of approximately 1:1 to 1:8.5. A relief or venting conduit is provided that extends into the vicinity of the highest location of the tire hollow chamber. Optionally, the rim breakthrough or valve leading to the tire hollow chamber is closed or sealed off. The valve for filling the tire hollow chamber, and the venting device may be arranged as a combined unit with respect to the rim body. The filling gas is introduced into the air-filled tire hollow chamber at an over-pressure; a pressure equalization is then brought about with respect to the atmosphere, and further filling gas is then introduced at over-pressure into the tire hollow chamber. The tire and rim may be permanently connected to each other in a gas-tight manner.
