07 Wheels and tiresGlossary of tire terminology
07174
•
Tire information placard: A placard
showing the OE (Original Equipment) tire
sizes, recommended inflation pressure,
and the maximum weight the vehicle can
carry.
•
Tire Identification Number (TIN): A num-
ber on the sidewall of each tire providing
information about the tire brand and man-
ufacturing plant, tire size and date of man-
ufacturer.
•
Inflation pressure: A measure of the
amount of air in a tire.
•
Standard load: A class of P-metric or Met-
ric tires designed to carry a maximum load
at 35 psi [37 psi (2.5 bar) for Metric tires].
Increasing the inflation pressure beyond
this pressure will not increase the tires load
carrying capability.
•
Extra load: A class of P-metric or Metric
tires designed to carry a heavier maximum
load at 41 psi [43 psi (2.9 bar) for Metric
tires]. Increasing the inflation pressure
beyond this pressure will not increase the
tires load carrying capability.
•
kPa: Kilopascal, a metric unit of air pres-
sure.
•
PSI: Pounds per square inch, a standard
unit of air pressure.
•
B-pillar: The structural member at the side
of the vehicle behind the front door.
•
Bead area of the tire: Area of the tire next
to the rim.
•
Sidewall of the tire: Area between the
bead area and the tread.
•
Tread area of the tire: Area of the perim-
eter of the tire that contacts the road when
mounted on the vehicle.
•
Rim: The metal support (wheel) for a tire or
a tire and tube assembly upon which the
tire beads are seated.
•
Maximum load rating: a figure indicating
the maximum load in pounds and kilo-
grams that can be carried by the tire. This
rating is established by the tire manufac-
turer.
•
Maximum permissible inflation pres-
sure: the greatest amount of air pressure
that should ever be put in the tire. This limit
is set by the tire manufacturer.
•
Recommended tire inflation pressure:
inflation pressure, established by Volvo,
which is based on the type of tires that are
mounted on a vehicle at the factory. This
inflation pressure is affected by the number
of occupants in the vehicle, the amount of
cargo, and the speed at which the vehicle
will be driven for a prolonged period. This
information can be found on the tire infla-
tion placard(s) located on the driver's side
B-pillar or on the inside of the fuel filler dooron Canadian models, and in the tire infla-
tion table in this chapter.
•
Cold tires: The tires are considered to be
cold when they have the same temperature
as the surrounding (ambient) air. This tem-
perature is normally reached after the vehi-
cle has been parked for at least 3 hours.

07 Wheels and tiresUniform Tire Quality Grading
07176
ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY
REQUIREMENTS IN ADDITION TO THESE
GRADES
Quality grades can be found, where appli-
cable, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature ATREADWEARThe 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 gra-
ded 150 would wear one and one half (1 1/2)
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.TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test sur-
faces 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
(turning) traction.TEMPERATUREThe temperature grades are AA (the highest),
A, B, and C, representing the tire's resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled con-
ditions 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 corre-
sponds 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.

Attaching the jack•
Place the jack on the ground, under one of
the attachment points (see the illustration)
and crank while simultaneously guiding the
jack's attachment bracket onto the attach-
ment point (see illustration) The base of the
jack must be flat on a level, firm, non-slip-
pery surface. Before raising the vehicle,
check that the jack is still correctly posi-
tioned in the attachment.
•
Raise the vehicle until the wheel to be
changed is lifted off the ground.
•
Unscrew the wheel bolts completely and
carefully remove the wheel so as not to
damage the threads on the studs.
NOTE
To avoid excessive wear and the necessity
of rebalancing, mark and reinstall wheels in
the same location and position as before
removal. To lessen the chance of imbal-
ance, each wheel hub is equipped with a
guide stud to ensure that a removed wheel
can be reinstalled in its original position (as
when changing over to winter tires/wheels).Installing the wheel1. Clean the contact surfaces on the wheel
and hub.
2. Lift the wheel and place it on the hub.3. Install the wheel bolts and tighten hand-
tight. Using the lug wrench, tighten cross-
wise until all bolts are snug.
4. Lower the vehicle to the ground and alter-
nately tighten the bolts crosswise to
102 ft.lbs. (140 Nm).
5. Install the wheel cap (where applicable).

Tire Sealing System
07``185 Introduction
Certain models are equipped with a tire sealing
system that enables you to temporarily seal a
hole in the tread surface and re-inflate a flat tire,
or to adjust a tire’s inflation pressure.
The system consists of an air compressor, a
container for the sealing compound, wiring to
connect the system to the vehicle’s electrical
system via one of the 12-volt sockets, and a
hose used to connect the system to the tire’s
inflation valve.
The 12-volt sockets are located on the rear side
of the center console (in the rear seat) and in
the cargo area.Accessing the tire sealing systemThe tire sealing system is stowed under the
floor of the cargo area. To access it:
1. Fold up or remove any protective floor cov-
ering or carpet.
2. Open the floor hatch.
3. Lift out the tire sealing system.
NOTE
•
The tire sealing system is only intended
to seal holes on the tire’s tread area, not
the sidewall.
•
Tires with large holes or tears cannot be
repaired with the tire sealing system.WARNING
•
After using the tire sealing system, the
vehicle should not be driven farther than
approximately 120 miles (200 km).
•
Have the tire inspected by a trained and
qualified Volvo service technician as
soon as possible to determine if it can
be permanently repaired or must be
replaced.
•
The vehicle should not be driven faster
than 50 mph (80 km/h) while using a tire
that has been temporarily repaired with
the tire sealing system.
•
After using the tire sealing system, drive
carefully and avoid abrupt steering
maneuvers and sudden stops.

Please keep the following points in mind
when using the tire sealing system:•
The sealing compound bottle (no. 8 in
the illustration) contains 1.2-Ethanol
and natural rubber-latex. These sub-
stances are harmful if swallowed.
•
The contents of this bottle may cause
allergic skin reactions or otherwise be
potentially harmful to the skin, the cen-
tral nervous system, and the eyes.
Precautions:
•
Keep out of reach of children.
•
Do not ingest the contents.
•
Avoid prolonged or repeated contact
with the skin.
•
Hands should be washed thoroughly
after handling.
First aid:
•
Skin: Wash affected areas of skin with
soap and water. Get medical attention
if symptoms occur.
•
Eyes: Flush with plenty of water for least
15 minutes, occasionally lifting the
upper and lower eyelids. Get medical
attention if symptoms occur.
•
Inhalation: Move the person to fresh air.
If irritation persists, get medical atten-
tion.
Tire sealing system–temporarily
repairing a flat tire
G014338
Temporarily repairing a flat tire is done in two
stages:
•
Stage 1: The hole is sealed by pumping
sealing compound into the tire. The car is
then driven a short distance to distribute
the sealing compound in the tire.NOTE
Do not remove any foreign objects (nails,
etc.) from the tire before using the sealing
system.•
Stage 2: The tire’s inflation pressure is
checked and adjusted if necessary.WARNING
•
Never leave the tire sealing system
unattended when it is operating.
•
Keep the tire sealing system away from
children.
•
Be sure the vehicle is parked safely off
the road and away from moving traffic.
•
Apply the parking brake.
Stage 1: Sealing the hole1. Open the cover on the tire sealing kit.
2. Peel off the speed limit sticker and affix it
to the steering wheel hub where it will be
clearly visible to the driver.

3. Ensure that the on/off switch is in position
0 (the 0 side of the switch should be
pressed down).
4. Put on the gloves included in the tire seal-
ing system.
WARNING
Contact with the sealing compound may
cause skin irritation. If contact occurs, wash
the affected area immediately with soap and
water.5. Unscrew the orange cover over the bottle
holder and unscrew the cap on the bottle
of sealing compound.
NOTE
Do not break the seal on the bottle. This
occurs automatically when the bottle is
screwed into the holder.6. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep
it securely in place and help prevent sealing
compound leakage. Once in place, the bot-
tle cannot be unscrewed. This must be done
by a trained and qualified Volvo service
technician.7. Remove the valve cap from the tire’s infla-
tion valve and screw the tire sealing sys-
tem’s hose connector onto the valve as
tightly as possible by hand.
8. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
9. Start the vehicle’s engine.
10. Start the tire sealing system’s compressor
by pressing the on/off switch to position I.
WARNING
•Never stand next to the tire being inflated
when the compressor is in operation.•If cracks, bubbles, etc. form on the tire,
switch off the compressor immediately.•If there is visible damage to the sidewall
or the rim, the tire cannot be repaired.
The vehicle should not be driven if this
occurs. Contact a towing service or
Volvo On Call Roadside Assistance if
applicable.NOTE
The air pressure gauge will temporarily
show an increase in pressure to approxi-
mately 88 psi (6 bar) while the sealing com-
pound is being pumped into the tire. The
pressure should return to a normal level
after approximately 30 seconds.11. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch
off the compressor briefly to get a clear
reading from the pressure gauge. The
compressor should not be used for more
than 10 minutes at a time to avoid over-
heating.

CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If the pressure remains below 22 psi (1.8
bar) after approximately seven minutes, turn
off the compressor. In this case, the hole is
too large to be sealed and the vehicle should
not be driven.12. Switch off the compressor and disconnect
the electrical wire from the 12-volt socket.
13. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
14. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed
of 50 mph (80 km/h) to distribute the seal-
ing compound in the tire.
NOTE
•
Safely stow the tire sealing system in a
convenient place as it will soon be used
again to check the tire’s inflation pres-
sure.
•
The empty bottle of sealing compound
cannot be removed from the bottle
holder. Consult a trained and qualified
Volvo service technician to have the
bottle removed and properly disposed
of.WARNING
If heavy vibrations, unsteady steering
behavior, or noises should occur while driv-
ing, reduce speed and park the vehicle in a
safe place. Recheck the tire for bumps,
cracks, or other visible damage, and
recheck its inflation pressure. If the pressure
is below 19 psi (1.3 bar), do not continue
driving. Have the vehicle towed to a trained
and qualified Volvo service technician.Stage 2: Checking inflation pressure1. Connect the tire sealing system as descri-
bed in stage 1.
2. Refer to the inflation pressure tablesfor the
correct inflation pressure. If the tire needs
to be inflated, start the tire sealing system’s
compressor. If necessary, release air fromthe tire by turning the air release knob
counterclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If you interrupt your trip for more than 1
hour, check the inflation pressure in the
damaged tire again before continuing.Replacing the sealing compound
containerThe sealing compound container must be
replaced if:•
the tire sealing system has been used to
repair a tire
•
the container’s expiration date has passed
(see the date on decal).
