195 = Tyre width, mm
65 = Cross-section ratio (tyre
height to tyre width), %
R = Belt type: Radial
RF = Type: RunFlat
15 = Wheel diameter, inches
91 = Load index e.g. 91 is
equivalent to 618 kg
H = Speed code letter
Speed code letter:
Q = up to 100 mph
S = up to 112 mph
T = up to 118 mph

Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring.
Remove the valve cap key from the
fuel filler flap and use it to unscrew the
valve cap.
On vehicles with tyre pressure
monitoring system, screw the adapter
to the valve.
The tyre pressure data 3 208 refer to
cold tyres. It applies to summer and
winter tyres.
Always inflate the spare wheel to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible. It must not be
used with run-flat tyres.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
