The tire mobility system is a repair kit with which the driver can quickly and easily fix air leaks. The kit contains sealant and a 12-volt compressor to inflate the tire. In this way damage caused by foreign objects (up to 6 mm in diameter) can be reliably sealed. The tire mobility system is thus a lightweight, space-saving alternative to the conventional spare tire. It makes it possible to drive (at a maximum of 80 km/h) to the nearest workshop. Models having the tire mobility system as standard equipment can be supplied instead with a temporary spare wheel.
