Tires With Emergency Running Characteristics, SST (Self-Supporting Tire): Notes
Run-flat tires, removing and installing, refer to RUN-FLAT TIRES, REMOVING AND MOUNTING .
Only vehicles with a tire pressure monitoring system are equipped with SST tires. This warns the driver when tire pressure falls below a certain value.
Tire damage and the pressure loss resulting from it is not always recognizable.
Driving can continue at a maximum of 80 km/h (50 mph) up to a distance of 50 km (31 miles) with complete loss of pressure.
Observe the special mounting information for SST tires.
Mixed installation of SST tires and standard tires is not permitted, and not on the same axle. A standard tire can only be installed in exception cases for a short time or a limited driving distance. However, the SST-specific flat running characteristics no longer apply. The driver must be explicitly informed of this.
In an emergency, the responsibility lies with the driver to decide after checking whether the affected tire can be driven farther, refer to the Owner's Manual.
Retrofitting only with tires approved for this (EH2 - extended hump rim contour).
