In addition to the standard tires, run-flattires are
also optionally available. These tires have a
reinforced sidewall and provide the advantage that
the tire maintains its shape to a large extent even
in the event of insufficient tire pressure. This
ensures that the vehicle handling remains stable.
Advantage:
• These tires maintain their shape to a large extent, even in the event of insufficient tire
pressure. This ensures that the vehicle handling
remains stable.
Special wheel rims (EH2) and a tire pressure
monitoring system are needed for run-flat tires.
Standard tires can also be installed on the EH2
(EH = Extended Hump) wheel rims. Tires with
run-flat properties have the same size code and
the same appearance as standard tires.
With some tires, the code RFfor run-flat is included
in the tire designation, e.g. 205/55 RF16. Tires with run-flat properties have various different
codes on the sidewall, depending on the
manufacturer.
• The RFT logo
• "RUNFLAT" as an additional designation
• The additional designation "RSC" (RSC =
Runflat System Component)
• The additional designation "SSR" (SSR = Self
S upporting Run-Flat-Tire)
• The additional designation "SST" (SST = Self
S upporting Run-Flat- Tire)
WARNING: If a tire with run-flat properties
is used without air then the vehicle speed
must not exceed 80 km/h and the vehicle
must not be driven for distances in excess
of 80 km.
Note: Vehicles equipped at the factory with run-flat
tires do not feature a tire repair kit or a spare wheel.
