224 Driving and operation
Wheels, tyres
see page 337 for suitable tyres and
restrictions.
Tyres fitted in the factory are adapted to
the chassis and provide optimum driving
comfort and safety.
Changing tyre/wheel type
Before conversion to other tyres or wheels,
note the changes required.
If tyres of a different size than those fitted
at the factory are used, the electronic
speedometer may require reprogramming
to ensure that the correct speed is
displayed.
Vehicles with tyre pressure monitoring
sy ste m 3
With winter tyres or after conversion to
different wheel sizes, sensors for the tyre
pressure monitoring system can be fitted
by a workshop on request. Otherwise the
system would not show the tyre pressure
deviations.
Deflation detection system 3 – see
page 217, tyre pressure monitoring
system 3 – see page 218.
Vehicles with run-flat tyres 3
When switching wheels, e.g. when
switching to winter tyres, use run-flat tyres
as there is no spare wheel or tyre repair kit
in the vehicle.
Run-flat tyres - see page 229.
Fitting new tyres
Fit tyres in pairs or in sets, which is even
better. Ensure that tyres on one axle are
z the same size
z the same design
z the same make
z and have the same tread pattern.
Fit directional tyres such that they roll in the
direction of travel. The rolling direction is
indicated by a symbol (e.g. an arrow) on
the sidewall.
Tyres fitted opposing the rolling direction
(e.g. when a tyre is changed) should be
refitted as soon as possible. This is the only
way to obtain full benefit from the design
properties of the tyre.
9 Warning
Use of unsuitable tyres or wheels may
lead to accidents and render the vehicle
unroadworthy.
