General information
Your vehicle is equipped with tires according to the vehicle's tire info\
rmation placard on the B-pillar (the
structural member at the side of the vehicle, at the rear of the driver'\
s door opening), or on the inside of
the fuel filler door on Canadian models.
The tires have good road holding characteristics and offer good handling\
on dry and wet surfaces. It
should be noted however that the tires have been developed to give these\
features on snow/ice-free
surfaces.
Certain models are equipped with "all-season" tires, which provide a som\
ewhat higher degree of road
holding on slippery surfaces than tires without the "all-season" rating.\
However, for optimum road
holding on icy or snow-covered roads, we recommend suitable winter tires\
on all four wheels.
When replacing tires, be sure that the new tires are the same size desig\
nation, type (radial) and preferably
from the same manufacturer, on all four wheels. Otherwise there is a ris\
k of altering the car's roadholding
and handling characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be s\
uspended off the floor or placed
on their sides on the floor.
Tires not mounted on rims should be stored on their sides or standing up\
right, 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.
WARNING
l The wheel and tire sizes for your are specified to meet stringent stabil\
ity and handling requirements.
Unapproved wheel/ tire size combinations can negatively affect your vehi\
cle's stability and handling.
Approved tire sizes are shown in the Tire inflation pressure tables on
pages 156 and 157.
l Any damage caused by installation of unapproved wheel/tire size combinat\
ions will not be covered
by your new vehicle warranty. Volvo assumes no responsibility for death,\
injury, or expenses that may
result from such installations.

The tires have wear indicator strips running across or parallel to the t\
read. The letters TWI are printed on
the side of the tire. When approximately 1/16" (1.6 mm) is left on the\
tread, these strips become visible
and indicate that the tire should be replaced. Tires with less than 1/16\
" (1.6 mm) tread offer very poor
traction.
When replacing worn tires, it is recommended that the tire be identical \
in type (radial) and size as the one
being replaced. Using a tire of the same make (manufacturer) will prev\
ent alteration of the driving
characteristics of the vehicle.

General information
New Tires
Remember that tires are perishable goods. As of 2000, the manufacturing \
week and year (Department of
Transportation (DOT) stamp) will be indicated with 4 digits (e.g. 15\
02 means that the tire illustrated was
manufactured during week 15 of 2002).
Tire age
Tires degrade over time, even when they are not being used. It is recomm\
ended that tires generally be
replaced after 6 years of normal service. Heat caused by hot climates, f\
requent high loading conditions or
Ultra Violet (U.V) exposure can accelerate the aging process.

You should replace the spare tire when you replace the other road tires \
due to the aging of the spare.
A tire's age can be determined by the DOT stamp on the sidewall (see th\
e illustration above).
A tire with e.g., visible cracks or discoloration should be replaced imm\
ediately.
Improving tire economy
l Maintain correct tire pressure. See the tire pressure tables on pages 156 and 157.
l Drive smoothly: avoid fast starts, hard braking and tire screeching.
l Tire wear increases with speed.
l Correct front wheel alignment is very important.
l Unbalanced wheels impair tire economy and driving comfort.
l Tires must maintain the same direction of rotation throughout their life\
time.
l 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.
l Hitting curbs or potholes can damage the tires and/or wheels permanently\
.

tire inflation pressure placard is also located on the driver's side Bpi\
llar (the structural member at the side
of the vehicle, at the rear of the driver's door opening). This placard\
indicates the designation of the
factory-mounted tires on your vehicle, as well as load limits and inflat\
ion pressure.
NOTE
The placards shown indicate inflation pressure for the tires installed o\
n the car at the factory
only.
l Use a tire gauge to check the tire inflation pressure, including the spa\
re, at least once a month and
before long trips. You are strongly urged to buy a reliable tire pressur\
e gauge, as automatic service station
gauges may be inaccurate.
l Use the recommended cold inflation pressure for optimum tire performance\
and wear.
l Under-inflation or over-inflation may cause uneven treadwear patterns.
WARNING
l Under-inflation is the most common cause of tire failure and may result \
in severe tire cracking, tread
separation, or "blowout," with unexpected loss of vehicle control and in\
creased risk of injury.
l Under-inflated tires reduce the load carrying capacity of your vehicle. \
When weather temperature changes occur, tire inflation pressures also ch\
ange. A 10- degree temperature
drop causes a corresponding drop of 1 psi (7 kPa) in inflation pressur\
e. Check your tire pressures
frequently and adjust them to the proper pressure, which can be found on\
the vehicle's tire information
placard or certification label.

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 car has been parked for a\
t least 3 hours.

Tire inflation
After driving a distance of approximately 1 mile (1.6 km), the tires a\
re considered to be hot. If you have
to drive farther than this distance to pump your tire(s), check and re\
cord the tire pressure first and add the
appropriate air pressure when you get to the pump.
If checking tire pressure when the tire is hot, never "bleed" or reduce \
air pressure. The tires are hot from
driving and it is normal for pressures to increase above recommended col\
d pressures. A hot tire at or
below recommended cold inflation pressure could be significantly under-i\
nflated.
To check inflation pressure
1. Remove the cap from the valve on one tire, then firmly press the tire\
gauge onto the valve.
2. Add air to reach the recommended air pressure
3. Replace the valve cap.
4. Repeat this procedure for each tire, including the spare.
5. Visually inspect the tires to make sure there are no nails or other o\
bjects embedded that could puncture
the tire and cause an air leak.
6. Check the sidewalls to make sure there are no gouges, cuts, bulges or\
other irregularities.
NOTE
l If you overfill the tire, release air by pushing on the metal stem in th\
e center of the valve. Then
recheck the pressure with your tire gauge.
l Some spare tires require higher inflation pressure than the other tires.\
Consult the tire inflation tables
on
pages 156 and 157 or see the inflation pressure placard.

Federal law mandates that tire manufacturers place standardized informat\
ion on the sidewall of all tires
(see the illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire desi\
gnation):
1. 215: the width of the tire (in millimeters) from sidewall edge to sidewal\
l edge. The larger the number,
the wider the tire.
2. 65: The ratio of the tire's height to its width.
3. R: Radial tire.
4. 15: The diameter of the wheel rim (in inches).
5. 95: The tire's load index. In this example, a load index of 95 equals a ma\
ximum load of 1521 lbs (690
kg).
6. H: The tire's speed rating, or the maximum speed at which the tire is des\
igned to be driven for extended
periods of time, carrying a permissible load for the vehicle, and with c\
orrect inflation pressure. For
example, H indicates a speed rating of 130 mph (210 km/h).
NOTE
This information may not appear on the tire because it is not required b\
y
law.
7. M+S or M/S = Mud and Snow, AT = All Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN): This begins with the letters "DOT" and indicates that
the tire meets all federal standards. The next two numbers or letters ar\
e the plant code where it was
manufactured, the next two are the tire size code and the last four numb\
ers represent the week and year
the tire was built. For example, the numbers 317 mean the 31st week of 1\
997. After 2000 the numbers go
to four digits. For example, 2501 means the 25th week of 2001. The numbe\
rs in between are marketing
codes used at the manufacturer's discretion. This information helps a ti\
re manufacturer identify a tire for
safety recall purposes.
9. Tire Ply Composition and Material Used: Indicates the number of plies indicates or the number of
layers of rubber-coated fabric in the tire tread and sidewall. Tire manu\
facturers also must indicate the ply
materials in the tire and the sidewall, which include steel, nylon, poly\
ester, and others.
