Tires

The function of the tires is to carry loads, pro-
vide traction on road surfaces, reduce vibra-
tions and protect the wheels from wear.

The tires significantly influence the vehicle's
driving characteristics. The type, dimensions,
tire pressure and speed rating have a consid-
erable impact on how the vehicle performs.

Your vehicle is equipped with tires according
to the vehicle's tire information placard on the
B-pillar (the structural member at the side of
the vehicle, at the rear of the driver's door
opening).

WARNING

A damaged tire could cause the driver to

lose control of the vehicle.

CAUTION

Some Volvo models are equipped with an
Ultra High Performance tire and wheel
combination designed to provide maxi-
mum dry pavement performance with con-
sideration for hydroplaning resistance.
They may be more susceptible to road haz-
ard damage and, depending on driving
conditions, may achieve a tread life of less
than 30,000 km (20,000 miles). Even if
this vehicle is equipped with Volvo's
advanced AWD or stability system, these
tires are not designed for winter driving,
and should be replaced with winter tires
when weather conditions dictate.

The tires have good road holding characteris-
tics and offer good handling on dry and wet
surfaces. It should be noted however that the
tires have been developed to give these fea-
tures on snow/ice-free surfaces.

Most models are equipped with "all-season"
tires, which provide a somewhat higher
degree of roadholding on slippery road surfa-
ces than tires without the "all-season" rating.
However, Volvo recommends using snow tires
on all four wheels for good roadholding on icy
or snow-covered roads.

When replacing tires, be sure that the new
tires are the same size designation, type
(radial) and preferably from the same manu-
facturer, on all four wheels. Otherwise there is
a risk of altering the vehicle's roadholding and
handling characteristics.

Recommended tires

On delivery, the car is equipped with Volvo
original tires that have the VOL

1

marking on

the side of the tires. These tires have been
designed specifically for your vehicle. It is
therefore important when replacing tires that
the new tires have this same marking to help
maintain the vehicle's driving characteristics,
comfort and fuel consumption.

New tires

This may vary for certain tire dimensions.

WHEELS AND TIRES

Tires are perishable goods. After a few years,
they will begin to harden and their friction
properties will gradually deteriorate. Always
replace tires with the freshest tires possible.
This is particularly important for snow tires. A
series of numbers is imprinted on the sidewall
of the tire. The last four digits in the series is
the Department of Transportation (DOT)
stamp and indicates the week and year the
tire was manufactured. The tire in the illustra-
tion has 0717 as the last four digits, which
means it was manufactured week 7 of 2017.

Tire age

Tires degrade over time, even when they are
not being used. It is recommended that tires
generally be replaced after 6 years of normal
service. Heat caused by hot climates, frequent
high loading conditions or Ultra Violet (U.V.)
exposure can accelerate the aging process.
The temporary spare

2

should also be replaced

at 6-year intervals, even if it has never been
used. A tire with e.g., visible cracks or discol-
oration should be replaced immediately.

Tire economy

•

Maintain correct tire pressure.

•

Avoid fast starts, hard braking and tire
screeching.

•

Tire wear increases with speed.

•

Correct front wheel alignment is very
important.

•

Unbalanced wheels impair tire economy
and driving comfort.

•

Tires must maintain the same direction of
rotation throughout their lifetime.

•

When replacing tires, the tires with the
most tread should be mounted on the rear
wheels to reduce the chance of oversteer
during hard braking.

•

Hitting curbs or potholes can damage the
tires and/or wheels permanently.

Tire rotation

Your vehicle has no required tire rotation. Driv-
ing style, tire pressure, climate and road con-
ditions affect how quickly the tires age and
exhibit signs of wear. Maintaining the correct
tire pressure helps keep tread wear evenly dis-
tributed.

To help prevent differences in tread depth and
wear patterns forming on the tires, the front
and rear wheels should be rotated, i.e. the
front tires moved to the rear and the rear tires
moved to the front. Ideally, tire rotation should
be done the first time after approximately
5000 km (ca 3100 miles) and thereafter at
10,000 km (approx. 6200 miles) intervals.

If you have any questions regarding tread
depth, Volvo recommends consulting an

authorized Volvo workshop. If significant dif-
ferences in wear (> 1 mm difference in tread
depth) between the tires have already occur-
red, the least worn tires should always be
mounted on the rear wheels. A front-wheel
skid (understeer) is usually easier to control
than a rear-wheel skid (oversteer). If the front
wheels skid, the vehicle will continue in a
straight line instead of the rear wheels skid-
ding to the side, which could cause you to
completely lose control of the vehicle. It is
therefore important that the rear wheels never
lose grip before the front wheels.

Storing wheels and tires

When storing complete wheels (tires mounted
on rims), they should be suspended off the
floor or placed on their sides on the floor.

Tires not mounted on rims should be stored on
their sides or standing upright, but should not
be suspended.

CAUTION

Tires should preferably be stored in a cool,
dry, dark place, and should never be stored
in close proximity to solvents, gasoline,
oils, etc.

Tire direction of rotation

Tires with tread designed to roll in only one
direction are marked with an arrow on the
sidewall.

The arrow shows the tire's direction of rotation.

•

The tire should maintain the same direc-
tion of rotation throughout its service life.

•

Tires should only be moved between the
front and back, never from right to left or
vice versa.

•

Incorrectly mounted tires impair the vehi-
cle's braking properties and ability to force
aside rain, snow and slush.

•

The tires with the most tread should
always be mounted on the rear wheels to
help reduce the risk of skidding.

NOTE

Use tires of the same type, dimensions and
make (manufacturer) on each axle.

Tread wear indicator

The tread wear indicator shows the status of
the tire's tread.

The tread wear indicator is a narrow elevated
strip running across the tire's longitudinal
tread grooves. The letters TWI (Tread Wear
Indicator) are visible on the side of the tire.
When approximately 1.6 mm (1/16 inch) is left
on the tread, the tread will be at the same
height as the tread wear indicator. Replace the
tire as soon as possible. Tires with low tread
offer very poor traction in rain or snow.

Uniform Tire Quality Grading

ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY
REQUIREMENTS IN ADDITION TO THESE
GRADES

.

Quality grades can be found, where applica-
ble, on the tire sidewall between the tread
shoulder and maximum section width. For
example:

Treadwear 200 Traction AA Temperature A

TREADWEAR

The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and one half (1 ½)
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and many depart signifi-
cantly from the norm due to variation in driving
habits, maintenance practices and differences
in road characteristics and climate.

TRACTION

The traction grades, from highest to lowest,
are AA, A, B, and C, as measured under con-
trolled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction perform-
ance.

WARNING

The traction grade assigned to this tire is

based on braking (straight-ahead) traction

tests and is not a measure of cornering

(turning) traction.

TEMPERATURE

The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a minimum level of performance that all
passenger vehicle tires must meet under the
Federal Motor Safety Standard No. 109.
Grades B and A represent higher levels of per-
formance on the laboratory test wheel than
the minimum required by law.

WARNING

The temperature grade for this tire is estab-

lished for a tire that is properly inflated and

not overloaded. Excessive speed, under-

inflation, or excessive loading, either sepa-

rately or in combination, can cause heat

buildup and tire failure.

Checking tire pressure

Correct inflation pressure helps improve driv-
ing stability, save fuel and increase the serv-
ice life of the tires.

Tire pressure decreases over time, which is
normal. Tire pressure also varies depending on
the ambient temperature. Driving on under-
inflated tires could cause the vehicle to over-
heat and lead to damage. Tire pressure affects
traveling comfort, road noise and driving cha-
racteristics.

Check the pressure in the tires every month.
Use the recommended inflation pressure for
cold tires to help maintain good tire perform-
ance. Under-inflated or over-inflated tires
could cause uneven tread wear.

Use an air pressure gauge and check the infla-
tion pressure on all the tires, including the
spare tire

4

, at least once a month and before

long trips. Volvo recommends buying a relia-
ble air pressure gauge, as the automatic
gauges provided at service stations may be
inaccurate.

WARNING

Under-inflation is the most common
cause of tire failure and may result in
severe tire cracking, tread separation,
or "blow-out," with unexpected loss of
vehicle control and increased risk of
injury.

•

Under-inflated tires reduce the load
carrying capacity of your vehicle.

Cold tires

Inflation pressure should be checked when the
tires are cold. The tires are considered to be
cold when they have the same temperature as
the surrounding (ambient) air. This tempera-
ture is normally reached after the vehicle has
been parked for at least 3 hours.

After driving for approximately 1.6 km (1 mile),
the tires are considered to be warm. If you
need to drive longer than that to inflate the
tires, check and record the inflation pressure
of the tires first and inflate accordingly when
you arrive at the pump.

When the ambient temperature changes, so
does the inflation pressure. A 10-degree tem-
perature drop causes a corresponding drop in
inflation pressure of 1 psi (7 kPa). Check the
inflation pressure of the tires regularly and
adjust to the correct pressure, which can be

found on the vehicle's tire information decal or
certification label.

If you check inflation pressure when the tires
are warm, you should never release air. The
tires become warm after driving and it is nor-
mal for warm tires to have an inflation pres-
sure above the recommended pressure for
cold tires. A warm tire with an inflation pres-
sure equal to or under the recommended pres-
sure for cold tires could be significantly under-
inflated.

Adjusting tire pressure

Tire pressure decreases over time, which is
normal. The tire pressure must therefore be
adjusted to maintain the recommended tire
pressure.

Use the recommended inflation pressure for
cold tires to help maintain good tire perform-
ance and even wear.

NOTE

To help prevent incorrect inflation pressure,
pressure should be checked when the tires
are cold. The tires are considered to be
cold when they have reached the same
temperature as the ambient temperature
(about 3 hours after the vehicle was last
driven). After driving for a few kilometers,
the tires will warm up and the pressure will
increase.

1. Remove the valve cap from the tire and

press the air pressure gauge firmly onto
the valve.

2. Inflate the tire to the correct inflation pres-

sure; see the tire pressure placard on the
driver's side B pillar for recommended
pressures for factory-mounted tires.

3. Screw the valve cap back on.

NOTE

•

After inflating a tire, always replace the
valve cap to help prevent valve damage
caused by gravel, dirt, etc.

•

Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.

4. Visually inspect the tire to make sure there

are no nails or other embedded objects
that could puncture the tire and cause air
leakage.

5. Check the sidewalls to make sure there

are no gouges, cuts, bulges or other irreg-
ularities.

6. Repeat this procedure for each tire, includ-

ing the spare tire

5

.

NOTE

If you have overfilled the tire, release air by
pushing on the metal stem in the center of
the valve. Then recheck the pressure with
your tire gauge.

Some spare tires require higher inflation
pressure than the other tires. Consult the
tire inflation pressure table or the inflation
pressure decal.

The tire inflation pressure monitoring system

6

provides an indicator symbol in the instru-
ment panel if pressure is too low in one or
more tires.

This symbol illuminates to
indicate low inflation pres-
sure. Check the inflation
pressure in the

Car Status

app in the center display.

If there is a system malfunc-

tion, the inflation pressure warning symbol will
flash for approximately one minute and then
glow steadily.

System description

The tire pressure monitoring system measures
differences in rotational speed between the
wheels through the ABS system to determine
if the tires are properly inflated. If inflation
pressure in a tire is too low, its diameter (and
consequently its rotational speed) changes. By
comparing the tires with each other, the sys-
tem can determine if the pressure in one or
more tires is too low.

General information about the tire pressure
monitoring system

In the following description, the tire monitor-
ing system is generally referred to as TPMS.

Each tire, including the spare (if provided)

7

should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size than
the size indicated on the vehicle placard or tire
inflation pressure label, you should determine
the proper tire inflation pressure for those
tires.)

As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure.

Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle's handling and stopping ability. Please

note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the
level to trigger illumination of the TPMS low
tire pressure telltale.

Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended.

TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the vehi-
cle that prevent the TPMS from functioning
properly.

Always check the TPMS malfunction telltale
after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.

To keep in mind

•

Always save the new inflation pressure in
the system after changing a tire or adjust-
ing the inflation pressure.

•

If you switch to a tire of another size than
the factory-mounted tires, the system
must be reset by storing a new inflation
pressure for these tires to avoid false
warnings.

•

If a spare wheel

8

is used, it is possible that

the tire pressure monitoring system will
not work correctly due to the differences
between the wheels.

•

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

•

It is not possible to deactivate the tire
pressure monitoring system.

WARNING

•

Incorrect inflation pressure could lead
to tire failure, which could cause the
driver to lose control of the vehicle.

•

The system cannot predict sudden tire
damage.

In order for the tire inflation pressure moni-
toring system

9

to function correctly, inflation

pressure reference values must be saved cor-
rectly. To help ensure that the system can
correctly alert the driver of low inflation pres-
sure, this must be done each time the tires
are changed or the inflation pressure is
adjusted.

For example, when driving with a heavy load
or at high speeds (over 160 km/h (100 mph)),
tire pressure should be adjusted to the Volvo-
recommended tire pressure values. The sys-
tem should then be reset by saving the new
inflation pressure.

To store the new inflation pressure as a refer-
ence value in the system:

1. Switch off the ignition.

2. Inflate the tire to the correct inflation pres-

sure; see the tire pressure placard on the
driver's side B pillar for recommended
pressures for factory-mounted tires.

3. Start the vehicle.

4. Open the

Car Status

app in App view.

5. Tap
