Dimension designation for wheel

rim

Wheel and rim dimensions are designated in
accordance with the examples in the table
below.

The car has an approval for the complete vehi-
cle with certain combinations of wheel rims
and tyres.

All wheel rims have a dimension designation,
for example: 7.5Jx18x50.5.

7.5

Rim width in inches

J

Rim flange profile

18

Rim diameter in inches

50.5 Off-set in mm (distance from wheel

centre to wheel contact surface
against the hub)

Tyres' rotation direction

Tyres with a tread pattern which are designed
to only turn in one direction have the direc-
tion of rotation marked with an arrow.

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).

NOTE

Make sure that both pairs of wheels have
the same type and dimension, and also the
same make.

Tread wear indicators on the tyres

Tread wear indicators show the status of the
tyre's tread depth.

A tread wear indicator 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 (1/16
inch), 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 (p. 550)

Checking tyre pressure

Correct tyre pressure helps to improve driv-
ing stability, save fuel and extend the service
life of the tyres.

Tyre pressure decreases over time, this is a
natural phenomenon. Tyre pressure also varies
depending on ambient temperature. 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.

Check the tyre pressures monthly. Use the
recommended tyre pressure for cold tyres in
order to maintain good tyre performance. Tyre
pressure that is too low or too high may cause
uneven wear on the tyres.

WARNING

•

Tyre pressure that is too low is the
most common cause of tyre failure and
may result in serious cracks in the tyre,
the tread loosening or the tyre explod-
ing, with unexpected loss of control of
the car and increased risk of personal
injury.

•

Tyres with pressure that is too low
reduce the load capacity of the car.

Cold tyres

The tyre pressure must be checked when the
tyres are cold. Tyres are considered cold when
they have the same temperature as the sur-
rounding air. This temperature is normally
reached when the car has been parked for at
least three hours.

After having driven approximately 1.6 km
(1 mile) these tyres are considered as warm. If
you have to drive further than this to inflate the
tyres, first check and record the tyre pressure
and inflate to a suitable tyre pressure when
you arrive at the pump.

When the outside temperature changes, the
tyre pressure also changes. A decrease in tem-
perature of 10 degrees causes the tyre pres-
sure to decrease 1 psi (7 kPa). Check the tyre
pressure regularly and adjust to the correct
pressure, which is specified on the car's tyre
information decal or certification label.

If you check the tyre pressure when the tyres
are warm then you must never release any air.
The tyres are warm due to driving and it is nor-
mal for the pressure to increase above the rec-
ommended pressure for cold tyres. A warm
tyre with tyre pressure equal to or below the
recommendation for cold tyres may have a
pressure that is far too low.

Adjusting tyre pressure

Tyre pressure decreases over time, this is a
natural phenomenon. The tyre pressure must
therefore sometimes be adjusted in order to
maintain the recommended tyre pressure.

Use the recommended tyre pressure for cold
tyres in order to maintain good tyre perform-
ance and even tread wear.

NOTE

To avoid incorrect tyre pressure, the pres-
sure should be checked on cold tyres.
"Cold tyres" means the tyres are the same
temperature as the ambient temperature
(approx. 3 hours after the car has been
driven). After a few kilometres of driving,
the tyres warm up and the pressure increa-
ses.

1. Remove the cap from the valve on one

tyre and then press the tyre pressure
gauge firmly down onto the valve.

2. Inflate the tyres to the correct pressure,

see the decal on the door pillar on the driv-
er's side showing the recommended pres-
sure for factory fitted tyres.

3. Refit the dust cap.

NOTE

•

After a tyre has been inflated, always
refit the dust cap in order to avoid dam-
age to the valve from gravel, dirt, etc.

•

Only use plastic dust caps. Metal dust
caps can rust and become difficult to
unscrew.

4. Check the tyres visually for any implanted

nails or other objects that could puncture
the tyre and cause leakage.

5. Check the sidewalls for any cavities, cuts,

bumps or other irregularities.

6. Repeat this for all tyres, including the

spare tyre

*

.

NOTE

If you have over-inflated, release air by
pressing in the metal pin in the centre of
the valve. Then check the pressure again
using the tyre pressure gauge.

Some spare tyres require a higher tyre
pressure than other tyres. Check in the tyre
pressure table or on the tyre pressure label.

Improved fuel economy with ECO pressure

For a light load (max. 3 people) and a speed of
up to 160 km/h (100 mph), the ECO pres-
sures can be chosen for good fuel economy.
However, the lower comfort pressures are rec-
ommended instead if improved noise and trav-
elling comfort are desired.

Tyre pressure monitoring system

*

The tyre pressure monitoring system

3

gives a

warning with an indicator symbol in the driver
display when the pressure in one or more of
the car's tyres is too low.

This symbol illuminates to
indicate low tyre pressure.
Check the tyre pressure in
the

Car Status

app in the

centre display.

If there is a fault in the sys-

tem the tyre pressure warning symbol flashes
for approximately one minute and then
remains illuminated.

System description

The tyre pressure monitoring system meas-
ures differences in rotation speed between the
different wheels via the ABS system in order
to be able to determine whether they have the
correct tyre pressure. If the tyre pressure is too
low, the tyre's diameter is changed and, as a
result, so is its rotation speed. By comparing
the tyres with each other the system can
determine whether one or more tyres have
pressure that is too low.

General information on the tyre monitoring
system

In the information below, the tyre monitoring
system is referred to generically as TPMS.

Each tyre, including the spare tyre

*

, should be

checked once a month. When checking, the
tyre should be cold and have the air pressure
recommended by the car manufacturer speci-
fied on the tyre pressure label or in the tyre
pressure table. If the car has tyres of a differ-
ent size than that recommended by the manu-
facturer, find out what the correct air pressure
level is for these.

As an extra safety feature, the car is equipped
with a tyre pressure monitoring system
(TPMS), which shows when the air pressure in
one or more tyres is too low. When the indica-
tor symbol for low air pressure is lit, stop and
check the tyres as soon as possible and inflate
to the correct air pressure.

Driving with tyres that have tyre pressure that
is too low may cause the tyre to overheat,
which can cause a tyre failure. Low tyre pres-
sure also reduces fuel efficiency as well as tyre
service life, and can affect car handling and
stopping ability. Note that TPMS does not
replace regular tyre maintenance. It is the driv-
er's responsibility to maintain correct tyre
pressure, even if the limit for low tyre pressure
has not been reached so that the indicator
symbol illuminates.

The car is also equipped with a TPMS system
fault indicator, which indicates when the sys-
tem is not functioning correctly. The TPMS

system fault indicator is combined with the
indicator symbol for low tyre pressure. When
the system detects a fault, the symbol in the
driver display will flash for about one minute
and then remain illuminated. This procedure
will be repeated when the car is started until
the fault has been rectified. When the symbol
is illuminated, the system's ability to detect or
warn of low tyre pressure may be affected.

A TPMS system fault can occur for several
reasons, such as after changing to a spare
tyre, or changing tyres or wheels that prevent
TPMS from functioning correctly.

Always check the indicator symbol for TPMS
after changing one or more tyres in order to
ensure the new tyre or wheel is working cor-
rectly with TPMS.

To bear in mind

•

Always save a new tyre pressure in the
system after changing a wheel or adjust-
ing tyre pressure.

•

If you change to tyres of a different size to
the ones fitted at the factory, the system
must be reset by storing a new tyre pres-
sure for these tyres to avoid false warn-
ings.

•

If a spare wheel

*

is used, it is possible that

not work correctly due to the differences
between the wheels.

•

The system does not replace the need for
regular tyre inspection and maintenance.

•

It is not possible to switch off the tyre
pressure monitoring system.

WARNING

•

Incorrect tyre pressure may lead to tyre
failure, which could result in the driver
losing control of the car.

•

The system cannot indicate sudden
tyre damage in advance.

Saving a new reference value for

tyre pressure monitoring

*

In order for the system for tyre pressure
monitoring

4

to work correctly, a reference

value for the tyre pressure must be saved.
This must take place every time the tyres are
changed or the tyre pressure is changed so
that the system can warn about low pressure
correctly.

For example, when driving with a heavy load
or at high speed above 160 km/h (100 mph),
the tyre pressure should be adjusted in
accordance with Volvo's recommended tyre
pressure values. The system is then reset by
saving a new tyre pressure.

Perform the following procedure to store a
new tyre pressure as a reference value in the
system:

1. Switch off the car.

2. Inflate the tyres to the correct pressure,

see the decal on the door pillar on the driv-
er's side showing the recommended pres-
sure for factory fitted tyres.

3. Start the car.

4. Open the

Car Status

app in the app view.

5. Press

TPMS

.

NOTE

The car must be stationary for the

Store

Pressure

button to be selectable.

6. Press

Store Pressure

.

7. Tap on

OK

to confirm that the tyre pres-

sure in all four tyres has been checked and
adjusted.

8. Drive the car until the new tyre pressure

has been saved. The new tyre pressure is
stored when the car is driven at a speed
above 35 km/h (22 mph).
> When sufficient data has been collec-

ted for the system to be able to detect
low tyre pressure, the animation show-
ing storage progress disappears from
the centre display. The system does not
provide additional confirmation that a
new tyre pressure has been saved.

If storing fails, a message is shown:

Storing

pressure unsuccessful. Try again.

mended. In this instance, follow the
instructions for use that come with the
equipment.

Removing a wheel

Read through all instructions before begin-
ning. Take out the tools needed before jacking
up the car.

1. Activate the hazard warning flashers and

set out a warning triangle if a wheel shall
be changed in a trafficked location.

2. Make sure that the parking brake is acti-

vated and engage gear position

3. Chock in front of and behind the wheels

that remain on the ground. Use, for exam-
ple, heavy wooden blocks or large stones.

4. Screw together the towing eye with the

wheel wrench to the stop position.

5. Remove the plastic caps from the wheel

bolts with the intended tool.

6. With the car still on the ground, use the

wheel bolt wrench/towing eye to undo the
wheel bolts ½-1 turn by pressing down-
wards (anticlockwise). Always start with
the lockable wheel bolts

with the lock screw.

IMPORTANT

Remember not to use bending force when
you loosen/tighten the wheel bolts. This
could damage the code groove in the lock
bolt and the wheel wrench and so make it
impossible to fit/remove the wheel.

When the wheel wrench is not in use it must
be stored in its place in the foam block under
the cargo area floor. It is important to remem-
ber this if the car is due to visit a workshop in

Spare wheel

*

The spare wheel, the Temporary Spare type,
can be used to temporarily replace a punc-
tured normal wheel.

The spare wheel is only designed for tempo-
rary use. Replace it with a normal wheel as
soon as possible.

The car's driving characteristics can be
changed when the spare wheel is used and
the ground clearance is reduced. Do not wash
the car in an automatic car wash if the
Temporary Spare is being used.

Recommended tyre pressure must be main-
tained regardless of the position of the tempo-
rary spare wheel on the car.

If the spare wheel is damaged, a new one can
be purchased from a Volvo dealer.

WARNING

•

Never drive faster than 80 km/h
(50 mph) with a spare wheel fitted on
the car.

•

The car must never be driven fitted
with more than one "Temporary Spare"
wheel.

•

The car may have different driving cha-
racteristics while driving with the spare
wheel. The spare wheel must be
replaced with a normal wheel as soon
as possible.

•

The spare wheel is smaller than the
normal wheel, which affects the car's
ground clearance. Look out for high
kerbs and do not machine-wash the
car.

•

Follow the manufacturer's recom-
mended tyre pressure for the spare
wheel.

•

On all-wheel drive cars, the drive on
the rear axle can be disengaged.

•

If the spare wheel is fitted to the front
axle then it is not possible to use snow
chains at the same time.

•

The spare wheel must not be repaired.

Winter tyres

Winter tyres are adapted for winter road con-
ditions.

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.

Tips for changing to winter tyres

When summer and winter wheels are
changed, mark which side of the car they were
mounted on, for example

Contact a Volvo dealer for advice on which rim
and tyre type suit your car best.

Studded tyres

Studded winter tyres should be run in gently
for 500-1000 km (300-600 miles), so the
studs settle properly into the tyres. This gives
the tyre, and especially the studs, a longer
service life.

NOTE

Laws regarding the use of studded tyres
may vary. Always follow local laws and
regulations.

Tread depth

Road conditions with ice, slush and low tem-
peratures place considerably higher demands

on tyres than summer conditions. Volvo there-
fore recommends not to drive on winter tyres
that have a tread depth of less than 4 mm
(0.15 inches).

Snow chains

Use of snow chains and/or winter tyres can
help to improve the traction in winter condi-
tions.

Volvo recommends that snow chains are not
used on wheel dimensions greater than
18 inches.

WARNING

Use Volvo genuine snow chains or equiva-

lent chains designed for the car model, and

tyre and rim dimensions. Only

single-sided

snow chains are permitted.
In the event of uncertainty about the show

chain, Volvo recommends that an author-

ised Volvo workshop should be contacted.

The wrong snow chains may cause serious

damage to the car and lead to an accident.

WHEELS AND TYRES

* Option/accessory.

IMPORTANT

Snow chains can be used on the car with
the following restrictions:

•

Always follow the mounting instruc-
tions from the manufacturer carefully.
Fit the chains as tensioned as possible
and tension them at regular intervals.

•

Snow chains must only be used on the
front wheels (also applies to all-wheel
drive cars).

•

In some cases, snow chains must NOT
be used, such as if accessory, after-
market or "special" tyres and wheels
are fitted that have a different size to
the original tyres and wheels. Suffi-
cient distance must be maintained
between the chains and brakes, sus-
pension and body components.

•

Check local regulations with regard to
using snow chains before fitting them.

•

Never exceed the chain manufacturer's
specified maximum speed. You must
never exceed 50 km/h (30 mph) under
any circumstances.

•

Avoid bumps, holes or sharp turns
when driving with snow chains.

•

Avoid driving on bare ground as this
wears out both the snow chains and
tyres.

•

Driving with snow chains may have a
negative effect on the car's driving
characteristics. Avoid fast or sharp
turns, as well as braking with locked
wheels.

•

Some types of chain that are firmly
tensioned affect brake components
and must therefore NOT be used.

You can obtain more information on snow
chains from a Volvo dealer.

Emergency puncture repair kit

The emergency puncture repair kit

8

, is used

to seal a puncture as well as to check and
adjust the air pressure in the tyre.

Cars equipped with spare tyre

*

do not have

the puncture repair kit.

The puncture repair kit consists of a compres-
sor and a bottle with sealing fluid. The sealing
works as a temporary repair.

NOTE

The sealing fluid is effective at sealing tyres
with tread punctures but has limited ability
to seal tyres with sidewall punctures. Do
not use the emergency puncture repair kit
on tyres displaying larger slits, cracks or
similar damage.

NOTE

The compressor is intended for temporary
emergency puncture repair and is
approved by Volvo.

Location

The puncture repair kit is located in the foam
block under the cargo area floor.
