WHEELS AND TYRES
Tyres
Amongst other things, the function of the tyres is
to carry load, provide grip on the road surface,
dampen vibration and protect the wheel from
wear.
The tyres greatly affect the car's driving characte-
ristics. The type of tyre, dimensions, tyre pressure
and speed rating are important for how the car
performs.
The car is fitted with tyres according to the tyre
information sticker found on the driver's side door
pillar (between the front door and the rear door).
WARNING
A damaged tyre may lead to loss of control
over the car.
Recommended tyres
On delivery, the car is equipped with Volvo origi-
1
nal tyres that have the VOL
of the tyres. These tyres are carefully adapted to
the car. In the event of changing tyres, it is there-
fore important that the new tyres also have this
marking in order for the car's driving characteris-
tics, comfort and fuel consumption to be main-
tained.
There may be deviations for certain tyre dimensions.

New tyres
Tyres are perishable. After a few years they begin
to harden at the same time as the friction
capacity/characteristics gradually deteriorate. For
this reason, aim to get as fresh tyres as possible
when you replace them. This is especially impor-
tant with regard to winter tyres. The last four dig-
its in the sequence mean the week and year of
manufacture. This is the tyre's DOT marking
marking on the side
(Department of Transportation), and this is stated
with four digits, for example 0717. The tyre is
then manufactured in week 07, year 2017.
Tyre age
All tyres older than 6 years old should be
checked by an expert even if they seem undam-
aged. Tyres age and decompose, even if they are
hardly ever or never used. The function can
therefore be affected. This applies to all tyres that
are stored for future use. Examples of external
signs which indicate that the tyre is unsuitable for
use are cracks or discolouration.
Tyre economy
Maintain the correct tyre pressure.
•
Avoid fast starts, heavy braking and squeal-
•
ing tyres.
Tyre wear increases with speed.
•
Correct wheel alignment is very important.
•
Unbalanced wheels worsen tyre economy
•
and travelling comfort.
The tyres must have the same direction of
•
rotation during their entire service life.
When you change tyres, the tyres with the
•
best tread must be fitted on the rear wheels
to reduce the risk of oversteer during heavy
braking.
If you drive over kerbstones or deep holes
•
you can damage the tyres and/or wheel rims
permanently.
Tyre rotation
The car has no mandatory tyre rotation. Driving
style, tyre pressure, climate and road condition
affect how quickly the tyres age and wear. Cor-
rect tyre pressure results in more even wear.
To avoid differences in tread depth and to pre-
vent wear patterns forming on the tyres, the front
