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

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

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

Features

• Results in no impairment of tire 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 tires and rims 
• Released for the Maybach from DaimlerChrysler as original equipment

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 (Tire 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.

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