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: 8Jx18x42.5.

8

Rim width in inches

J

Rim flange profile

18

Rim diameter in inches

42,5 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. 582)

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.

its and tyre pressure.

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.

The symbol illuminates to indicate
low tyre pressure.

If there is a fault in the system 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.

Messages on the instrument panel

When the tyre pressure is too low, the indica-
tor symbol for low tyre pressure is illuminated
in the driver display and a message is shown.

•

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

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.

If the car's ignition is switched off before the
new tyre pressure has been saved then the
procedure needs to be performed again. Allow
the storing to finish within the same driving
cycle to ensure that the new tyre pressure has
been saved correctly.

extinguish until the low tyre pressure has
been rectified and storing a new tyre pres-
sure has been started.

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.

NOTE

•

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

•

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

WARNING

The wheel bolts may need to be re-tight-

ened several days after the change. Tem-

perature differences and vibration may

mean that they are not attached equally as

tightly.

NOTE

•

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

•

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

Spare wheel

*

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

The spare tyre is only designed for temporary
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 tyre is damaged then 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.

IMPORTANT

The car must not be driven with tyres of
different sizes or with a spare tyre other
than the one supplied with the car. Using
different-sized wheels can cause serious
damage to the car's transmission.

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.

NOTE

Contact a Volvo dealer for advice about
which wheel rim and type of tyre are most
suitable.

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

L

for left and

R

for

right.

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

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