Tyre designations

E.g. 215/60 R 16 95 H
215 : Tyre width, mm
60 : Cross-section ratio (tyre height
to tyre width), %
R : Belt type: Radial
RF : Type: RunFlat
16 : Wheel diameter, inches
95 : Load index e.g. 95 is
equivalent to 690 kg
H : Speed code letter
Speed code letter:
Q : up to 160 km/h
S : up to 180 km/h
T : up to 190 km/h
H : up to 210 km/h
V : up to 240 km/h
W : up to 270 km/h
Choose a tyre appropiate for the

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 system.
Unscrew the valve cap.
Tyre pressure 3 254.
The tyre pressure information label
on the left door frame indicates the
original equipment tyres and the
correspondent tyre pressures.
Vehicle care
The tyre pressure data refers to cold
tyres. It applies to summer and winter
tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 248.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 254.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.
