Vehicle care291The tyre pressure data refers to cold
tyres. It applies to summer and winter
tyres.
Always inflate the spare tyre to the
highest pressure specified for this
tyre size.
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 type of drive.
2. Identify the gross vehicle weight.
3. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 315.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
Tyre pressure values provided on the
tyre information label and tyre
pressure chart are valid for cold tyres, which means at 20 °C. The pressure
increases by nearly 1.5 psi (10 kPa /
0.1 bar) for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
Trailer towing
When towing a trailer with a fully laden vehicle, the tyre pressure must
be increased by 20 kPa / 0.2 bar
(3.0 psi) and the maximum speed
limited to 60 mph.
Trailer towing 3 264.
Rear-wheel drive, with twin rear
wheels
When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
uses radio and sensor technology to
check tyre pressure levels.
