Abstract

A motor vehicle with a compressor assembly for the supply of a pressure medium to a tire cavity of a tire of a motor vehicle. The compressor assembly has a compression chamber which is rotationally fixed in relation to the motor vehicle wheel, and the compression chamber and the tire cavity are connected via a fluidic connection for the conveying of a pressure medium from the compression chamber into the tire cavity. A tire sealing device has a sealant reservoir with a first connection fluidically connected to a tire cavity of a tire of the motor vehicle to be repaired, and a second connection fluidically connected to a pressure medium source secured to the motor vehicle. The sealant is conveyed out of the pressure medium source into the tire cavity of the tire to be repaired by means of the pressure medium.
