Tyres - maintenance
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.
Driving characteristics
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.
Tyre age
All tyres older than 6 years old should be
checked by an expert even if they seem
undamaged. 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 indi-
cate that the tyre is unsuitable for use are
cracks or discoloration.
New tyres
Tyres are perishable. After a few years they
begin to harden at the same time as the fric-
tion capacity/characteristics gradually deteri-
orate. For this reason, aim to get as fresh
tyres as possible when you replace them.
This is especially important with regard to
winter tyres. The last four digits in the
sequence mean the week and year of manu-
facture. This is the tyre's DOT marking
(Department of Transportation), and this is
stated with four digits, for example 1510. The
tyre in the figure was manufactured in week
15 of 2010.
Summer and winter wheels
When summer and winter wheels are
changed the wheels should be marked with
which side of the car they were mounted on,
for example L for left and R for right.
Wear and maintenance
Correct tyre pressure (p. 323) results in more
even wear. Driving style, tyre pressure, cli-
mate and road condition affect how quickly
your tyres age and wear.
To avoid differences in tread depth and to
prevent wear patterns arising, the front and
rear wheels can be switched with each other.
A suitable distance for the first change is
approx. 5000 km and then at 10000 km inter-
vals.
Volvo recommends that an authorised Volvo
workshop is contacted for checking if you are
uncertain about tread depth. If significant dif-
ferences in wear (> 1 mm difference in tread
depth) between tyres have already occurred,
then the least worn tyres must always be fit-
ted on the rear. Understeer is normally easier
to correct than oversteer, and leads to the car
continuing forwards in a straight line rather
than having the rear end skidding to one side,
resulting in possible complete loss of control
over the car. This is why it is important for the
rear wheels never to lose grip before the front
wheels.
WARNING
A damaged tyre may lead to loss of control
over the car.

Tyres - direction of rotation
Tyres with a tread pattern which are designed
to only turn in one direction have the direction
of rotation marked with an arrow.
G021778
The arrow shows the tyre's direction of rotation.
The tyre must always rotate in the same
direction throughout its lifespan. Tyres should
only be switched between front and rear
positions, never between left and right-hand
sides, or vice versa. If the tyres are fitted
incorrectly, the car's braking characteristics
and capacity to force rain and slush out of the
way are adversely affected. Tyres with the
greatest tread depth should always be fitted
to the rear of the car (to decrease the risk of
skidding).
Make sure that both pairs of wheels have
the same type and dimension, and also the
same make.
Follow the recommended tyre pressures
specified in the tyre pressure table (p. 430).

Tyres - tread wear indicators
Tread wear indicators show the status of the
tyre's tread depth.
G021829
Tread wear indicators.
A tread wear indicators is a narrow elevation
across the longitudinal grooves of the tyre's
tread pattern. On the side of the tyre are the
letters TWI (Tread Wear Indicator). When the
tyre's tread depth is down to 1.6 mm, the
tread will be level in height with the tread
wear indicators. Change to new tyres as soon
as possible. Remember that tyres with little
tread depth provide very poor grip in rain and
snow.

Tyres - air pressure
Tyres can have different air pressures which
are measured in bar.
Check the air pressure in the tyres
The tyre pressures must be checked every
month.
This also applies to the car's spare wheel.

.
•
Spare tyre pressure (Temporary Spare).
Check the tyre pressure on cold tyres. "Cold
tyres" means the tyres are the same tempera-
ture as the ambient temperature. After several
few kilometres of driving, the tyres warm up
and the pressure increases.
Inadequate tyre pressure increases fuel con-
sumption, shortens tyre lifespan and impairs
the car's driving characteristics. Driving on
tyres with tyre pressure that is too low could
result in the tyres overheating and being
damaged. Tyre pressure affects travelling
comfort, road noise and driving characteris-
tics.
Tyre pressure decreases over time, this is
a natural phenomenon. Tyre pressure also
varies depending on ambient temperature.
Tyre pressure label
G021830
The tyre pressure label on the driver's side
door pillar (between frame and rear door)
shows which pressures the tyres should have
at different loads and speed conditions. This
is also specified in the tyre pressure table,
see Tyres - approved tyre pressures (p. 430).
Fuel economy, ECO pressure
In order to obtain optimum fuel economy at
speeds below 160 km/h an ECO pressure is
recommended (applies to both full and light
load), see Tyres - approved tyre pressures

WARNING
19-inch wheels must never be used on
cars that are not equipped with the R-
Design or Sport chassis options. The use
of 19-inch wheels on cars with standard
chassis constitutes a safety risk, with a
risk of vehicle damage, and it impairs the
car's driving characteristics.

Tyres - load index
Load index indicates a tyre's ability to carry a
certain load.
Each tyre has a certain capacity to carry a
load, a load index (LI). The car's weight deter-
mines the load capacity required of the tyres.
Minimum permissible index is indicated in the
load index table.

•
Tyres - approved tyre pressures (p. 430)

•
Tyres - speed ratings
Each tyre can withstand a certain maximum
speed and therefore belongs to a particular
speed rating (SS - Speed Symbol).
Tyre speed class must at least correspond
with the car's top speed. The table below
indicates the maximum permitted speed that
applies for each speed rating (SS). The only
exception to these regulations is the winter
tyre (p. 327)
, where a lower speed rating
may be used. If such a tyre is chosen, the car
must not be driven faster than the speed rat-
ing of the tyre (for example, class Q can be
driven at a maximum of 160 km/h). Traffic
regulations determine how fast a car can be
driven, not the speed rating of the tyres.
The maximum permitted speed is speci-
fied in the table.
Q
160 km/h (used only on winter tyres)
T
190 km/h
H
210 km/h
V
240 km/h
W
270 km/h
Y
300 km/h
WARNING
The car must be fitted with tyres which
have the same or a higher load index
(p. 326) (LI) and speed rating (SS) than
specified. If a tyre with too low a load
index or speed rating is used, it may over-
heat.

Wheel bolts
Wheel bolts are used to fasten the wheels at
the hubs and are available in different ver-
sions.
The wheel bolts must be tightened to 140
Nm. Overtightening can damage the nuts
and the bolts.
Only use rims that are tested and approved
by Volvo and which are Volvo genuine acces-
sories. Check the torque with a torque
wrench.
Locking wheel bolts*
Locking wheel bolts* can be used on both
aluminium and steel rims. Under the cargo
area floor there is space for the sleeve for the
lockable wheel bolts.

Wheel and wheel rim dimensions (p. 325)
Winter tyres
Winter tyres are tyres that are adapted for
winter road conditions.
Winter tyres
Volvo recommends winter tyres with particu-
lar dimensions. Tyre dimensions are depend-
ent on engine variant. When driving on winter
tyres, the correct type of tyres must be fitted
to all four wheels.
Volvo recommends that you consult a
Volvo dealer about which wheel rim and
tyre types are most suitable.
Studded tyres
Studded winter tyres should be run in gently
for 500-1000 km so the studs settle properly
into the tyres. This gives the tyre, and espe-
cially the studs, a longer service life.
The legal provisions for the use of studded
tyres vary from country to country.
Tread depth
Road conditions with ice, slush and low tem-
peratures place considerably higher demands
on tyres than summer conditions. Volvo
therefore recommends not to drive on winter
tyres that have a tread depth of less than
4 mm.
Using snow chains
Snow chains may only be used on the front
wheels (also applies to all-wheel drive cars).
Never drive faster than 50 km/h with snow
chains. Avoid driving on bare ground as this
wears out both the snow chains and tyres.
WARNING
Use Volvo genuine snow chains or equiva-
lent chains designed for the car model,
and tyre and rim dimensions. In the event
of uncertainty Volvo recommends that you
consult an authorised Volvo workshop.
The wrong snow chains may cause serious
damage to your car and lead to an acci-
dent.

Changing wheels - removing wheels
The car's wheels can be changed for e.g. win-
ter wheels/winter tyres.
Spare wheel*
The spare wheel (Temporary spare) is only
intended for use temporarily and must be
replaced by an ordinary wheel as soon as
possible. The car's handling may be altered
by the use of the spare wheel. The spare
wheel is smaller than the normal wheel. The
car's ground clearance is affected accord-
ingly. Pay attention to high kerbs and do not
machine wash the car. If the spare wheel is
fitted on the front axle, you cannot use snow
chains at the same time. On all-wheel drive
cars the drive on the rear axle can be discon-
nected. The spare wheel must not be
repaired.
The correct tyre pressure for the spare wheel
is stated in the tyre pressure table (p. 430).
•
Never drive faster than 80 km/h with a
spare wheel on the car.
•
The car must never be driven fitted
with more than one "Temporary
Spare" wheel.
The spare wheel is located in the spare wheel
well with the outside down. The same bolt
runs through to secure the spare wheel and
the foam block. The foam block contains all
the tools needed to change the wheels.
Taking out the spare wheel under the
cargo area floor
1. Fold up the cargo area floor, from the rear
and forwards.
2. Undo the retaining screw.
3. Lift out the foam block with its tools.
4. Lift out the spare wheel.
Removing
Set up warning triangle (p. 331) if a wheel is
replaced in trafficked location. The car and
jack* must be on a firm horizontal surface.
1. Apply the parking brake, (p. 295) and
engage reverse gear, or position P if the
car has an automatic gearbox.
WARNING
Check that the jack is not damaged, that
the threads are thoroughly lubricated and
that it is free from dirt.
Volvo recommends only using the jack*
that belongs to the car model in question,
which is indicated on the jack's label.
The label also indicates the jack's maxi-
mum lift capacity at a specified minimum
lifting height.
2. Take out jack*, wheel wrench*, removal
tool for wheel covers* and plastic wheel
bolt cap removal tool. They will be found
in the foam block. If another jack is
selected, see Raising the car (p. 358).
Tool for removing the plastic caps on the wheel

3. Place chocks in front of and behind the
wheels which will remain on the ground to
prevent them from rolling. Use heavy
wooden blocks or large stones for exam-
ple.
4. Cars with steel rims have removable
wheel covers. Use the removal tool to
hook in and pull off any full-wheel wheel
covers. Alternatively, the wheel covers
can be pulled away by hand.
5. Screw together the towing eye with the
wheel wrench* to the stop position.
The towing eye must be screwed all the
way into the wheel bolt wrench.
6. Remove the plastic caps from the wheel
bolts with the intended tool.
7. Loosen the wheel bolts ½-1 turn anti-
clockwise with the wheel wrench.
WARNING
Never position anything between the
ground and the jack, nor between the jack
and the car's jacking point.
8. There are two jacking points on each side
of the car. Wind up the jack so that the
flange in the bodywork ends up in the
notch in the head of the jack.
The ground must be firm, smooth and
level.
9. Lift the car so that the wheel is free.
Remove the wheel bolts and lift off the
wheel.

WARNING
Never crawl under the car when it is raised
on the jack.
Passengers must leave the car when it is
raised on the jack. If a wheel must be
changed in a trafficked environment, pas-
sengers must stand in a safe place.
The normal car jack is only designed for
occasional, short-term use, such as when
changing a wheel after a puncture, chang-
ing to winter/summer wheels, etc. Only the
jack for the specific car model may be
used to raise the car. If the car is to be
jacked up more often, or for a longer time
than is required just to change a wheel,
use of a garage jack is recommended. In
this instance, follow the instructions for
use that come with the equipment.

pressure monitoring is standard in accord-
ance with legal requirements.
There are two systems for tyre pressure
monitoring, TPMS (Tyre Pressure Monitoring
System) and TM (Tyre Monitor). In the event
of uncertainty about which system the car
has, open the menu system MY CAR and
search for the car's settings:
•

Tyre pressure monitoring uses sensors
located inside the air valve in each wheel.
When the car is driven at about 30 km/h the
system detects the tyre pressure. If the pres-
sure is too low then a warning lamp
illumi-
nates in the combined instrument panel and
one of the following messages is shown:
•
