Uniform Tire Quality Grading

ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY REQUIRE-
MENTS 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 gov-
ernment 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 significantly from the norm due
to variation in driving habits, maintenance practi-
ces and differences in road characteristics and
climate.

TRACTION

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

WARNING

The traction grade assigned to this tire is

based on braking (straight-ahead) traction

tests and is not a measure of cornering (turn-

ing) 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 exces-
sive 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 performance 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-infla-

tion, or excessive loading, either separately or

in combination, can cause heat buildup and

tire failure.

Checking tire pressure

Correct inflation pressure helps improve driving
stability, save fuel and increase the service life of
the tires.

Tire pressure decreases over time, which is nor-
mal. Tire pressure also varies depending on the
ambient temperature. Driving on under-inflated
tires could cause the vehicle to overheat and lead
to damage. Tire pressure affects traveling com-
fort, road noise and driving characteristics.

Check the pressure in the tires every month. Use
the recommended inflation pressure for cold tires
for optimal tire performance and wear. 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 strongly recommends buying a reliable air
pressure gauge, as the automatic gauges provi-
ded 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 vehi-
cle control and increased risk of injury.

•

Under-inflated tires reduce the load car-
rying 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 temperature 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 temperature
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 vehi-
cle's tire information placard 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 normal for
warm tires to have an inflation pressure above
the recommended pressure for cold tires. A warm
tire with an inflation pressure equal to or under
the recommended pressure for cold tires could
be significantly under-inflated.

Adjusting tire pressure

Tire pressure decreases over time, which is nor-
mal. The tire pressure must therefore be
adjusted to maintain the recommended tire pres-
sure.

Use the recommended inflation pressure for cold
tires for optimal tire performance and 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 tempera-
ture 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 pres-
sures 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 leak-
age.

5. Check the sidewalls to make sure there are

no gouges, cuts, bulges or other irregulari-
ties.

6. Repeat this procedure for each tire, including

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 pres-
sure than the other tires. Consult the tire
inflation pressure table or the inflation pres-
sure placard.

Tire pressure monitoring system*

The tire pressure monitoring system

6

 provides a

warning symbol in the instrument panel if pres-
sure is too low in one or more tires.

Symbol

Explanation

This symbol illuminates to indicate
low inflation pressure.

If there is a system malfunction, 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 system 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 monitoring
system is generally referred to as TPMS.

Each tire, including the spare (if provided)

7

should be checked monthly when cold and infla-

ted to the inflation pressure recommended 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 pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, 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 cau-
ses the tire to overheat and can lead to tire fail-
ure. Under-inflation also reduces fuel efficiency
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 main-
tenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-infla-
tion has not reached the level to trigger illumina-
tion 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 mal-
function indicator is combined with the low tire

6

552

pressure telltale. When the system detects a mal-
function, the telltale will flash for approximately
one minute and then remain continuously illumi-
nated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunc-
tion exists. When the malfunction indicator is illu-
minated, 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 replacement
or alternate tires or wheels on the vehicle 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 alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.

Messages in the instrument panel

If tire pressure is too low, the low tire pressure
warning symbol is shown in the instrument panel
along with a message.

Calibrating the tire pressure

monitoring system*

In order for the tire pressure monitoring system 

9

to function correctly, tire pressure reference val-
ues must be set correctly. This must be done
each time the tires are changed or the tire pres-
sure 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-recom-
mended tire pressure values. The system should
then be recalibrated.

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 pres-
sures for factory-mounted tires.

3. Start the vehicle.

4. Open the 

Car Status

 app in App view.

5. Tap 

TPMS

.

NOTE

The car must be stationary when calibration is
started.

6. Tap 

Calibrate

.

7. Tap 

OK

 to confirm that the tire pressure in

all four tires has been checked and adjusted.

8. Run the car until calibration is complete.

Calibration is done when the vehicle is driv-
ing at a speed above 35 km/h (22 mph).

If the car's ignition is switched off before cal-
ibration is complete, the tires in the center
display change color from gray to green upon
next start-up, even if calibration is not com-
plete. Perform the calibration again and allow
it to complete within the same operating
cycle to ensure that the calibration is carried
out correctly.
> When enough data has been collected for

the system to detect low tire pressure, the
color of the tire symbols in the center dis-
play will change from gray to green. The
system will not provide any other confir-
mation that calibration has been comple-
ted.

If start-up of calibration fails, the following
message appears: 

Calibration

unsuccessful. Try again.

NOTE

Always remember to calibrate the Tire Pres-
sure Monitoring System when the wheels
have been changed or the tire inflation pres-
sure has been corrected according to the tire
pressure decal or tire inflation pressure table.

If correct reference values have not been set,
the system cannot issue low tire pressure
alerts correctly.

The vehicle must be stationary with the
engine running to access the calibration but-
ton and to start the calibration process.

WARNING

The exhaust gases contain carbon monoxide,

which is invisible and odorless but very poi-

sonous. For this reason, always perform the

calibration procedure outdoors or in a work-

shop with exhaust gas evacuation equipment.

Spare wheel

15

The spare wheel is a Temporary Spare and can
be used to temporarily replace a punctured tire
on one of the vehicle's regular wheels.

The spare tire is only intended for temporary use.
Replace it with a normal wheel as soon as possi-
ble.

The driving characteristics of the vehicle change
and ground clearance reduces when the spare
wheel is used. Do not wash the vehicle in an
automatic car wash while using the Temporary
Spare.

The recommended tire pressure must be main-
tained regardless of at which position the tempo-
rary spare wheel is used on the vehicle.

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

WARNING

Current legislation prohibits the use of the

"Temporary Spare" tire other than as a tem-

porary replacement for a punctured tire. It

must be replaced as soon as possible by a

standard tire. Road holding and handling may

be affected with the "Temporary Spare" in

use. Do not drive faster than 80 km/h

(50 mph).

WARNING

•

The vehicle must never be driven with
more than one "Temporary Spare" tire
mounted.

•

Driving with a spare wheel may alter the
driving characteristics of the vehicle.
Replace the spare wheel with a normal
wheel as soon as possible.

•

The spare wheel is smaller than the nor-
mal wheel, which affects the vehicle's
ground clearance. Watch for high curbs
and do not wash the vehicle in an auto-
matic car wash when a spare wheel is
mounted.

•

Follow the manufacturer's recommended
tire inflation pressure for the spare wheel.

•

On all-wheel drive vehicles, the drive on
the rear axle can be disconnected.

•

If the spare wheel is mounted on the
front axle, snow chains must not be used.

•

The spare wheel must not be repaired.

CAUTION

The vehicle must not be driven with wheels of
different dimensions or with a spare tire other
than the one that came with the vehicle. The
use of different size wheels can seriously
damage your vehicle's transmission.

Accessing the spare wheel

Follow these instructions regarding handling the
spare wheel.

The spare wheel is stored in a bag and should be
secured with two straps onto the floor of the
trunk/cargo compartment when the vehicle is
being driven. The straps should be strapped
down crosswise over the wheel, attached to the
load anchoring eyelets and pulled taut.

Wheel changing tools are located under the
cargo compartment floor.

Snow tires

Snow tires are designed for winter driving.

Volvo recommends snow tires with specific
dimensions. The tire dimensions vary depending
on engine type. When driving with snow tires, the
correct type of tires must be mounted on all four
wheels.

NOTE

Contact a Volvo dealer for advice on the best
choice of rims and tires.

Tips for changing snow tires

When switching between regular tires and snow
tires, mark the tires according to which side they
were mounted on, e.g. L for left and R for right.

Studded tires

Studded tires should be broken in by driving
500–1000 km (300–600 miles) slowly and gen-
tly to help the studs settle properly in the tires.
This gives the tire, and especially the studs, a
longer service life.

NOTE

Regulations regarding the use of studded
tires vary from country to country.

Tread depth

Road conditions with ice, slush and low tempera-
tures place considerably higher demands on tires
than summer conditions. Volvo therefore recom-
mends not driving on snow tires that have a tread
depth of less than 4 mm (0.15 inch).

Snow chains

Using snow chains and/or snow tires can help
improve traction in winter driving conditions.

WARNING

Use Volvo genuine snow chains or equivalent

snow chains that are suitable for the vehicle

model and the tire and wheel sizes. Only one-

sided snow chains are permitted.
If uncertain about snow chains, Volvo recom-

mends contacting an authorized Volvo work-

shop. Use of the wrong snow chains could

cause serious damage to the vehicle and

result in an accident.
