ContiSupportRing (CSR)

Mobility in case of puncture

CSR is an innovative development that ensures the mobility of the vehicle in the event of a puncture.

  • Results in no impairment of tyre performance in normal operation
  • Ensures a range of up to 200 km in the event of a puncture
  • Easy to mount and demount with standard tyres and rims
  • Released for the Maybach from DaimlerChrysler as original equipment

Spare wheel: minus. Stowage: plus.

About the technology

The principle behind CSR is simple: A light stainless steel ring (1) with flexible support (2) is mounted with a standard tyre on a standard rim.

CSR has been developed especially for standard rims and standard tyres with higher side walls and larger profiles.

The tyre manufacturer Continental AG has been awarded the "Stahl-Innovationspreis 2006" in the Steel Products category. The prize honoured the ContiSupportRing runflat system.

CSR works for most common dimensions.

Technical details

Because of the good riding comfort CSR afford, drivers hardly notice any pressure loss in the event of a flat; to increase both safety in the event of a flat and performance during normal driving, the CSR system is supplied only together with an inflation warning system – either TPMS (Tyre Pressure Monitoring System) or DDS (Deflation Detection System), both of which were likewise developed by Continental.


These warning systems alert the driver when a drop in inflation pressure requires investigation via a display on the instrument panel. ContiSupportRing as well as the inflation warning systems TPMS/DDS are exclusively installed in original equipment.
