A hose-type structure is arranged essentially between the tire and the rim, which structure is connected at the end side with the environment and, by way of a valve, with the interior of the tire. The hose-type structure fills the tire during its rotating movement, and is locally squeezed from the environment side toward the tire interior, in which case the hose-type structure is provided in the area between the tire and the rim flange. A duct is provided in the rim flange or in the tire in the area of its bead chamfer, and at least partially receives the hose-type structure in the form of a hose. The geometry of the duct and of the hose-type structure is selected such that this air-conveying squeezing essentially takes place only as long as the internal tire pressure is below a desired value.
