chain information.
CAUTION:
l Check local regulations regarding the use of
snow chains before installing.
l Always follow the chains manufacturer's
installation instructions carefully. Install
chains as tightly as possible and re-tighten
periodically.
l Never exceed the chain manufacture's
specified maximum speed limit. (Under no
circumstances should that limit be higher than
30 mph (50 km/h).
l Avoid bumps, holes or sharp turns when
driving with snow chains.
l The handling of the vehicle can be adversely
affected when driving with chains. Avoid fast
or sharp turns as well as locked wheel braking.

Winter tires wear more quickly on dry roads in
warm weather. They should be removed when the
winter driving season has ended.

Studded tires should be run-in 300-600 miles
(500-1000 km) during which the car should be
driven as smoothly as possible to give the studs
the opportunity to seat properly in the tires. The
car tires should have the same rotational direction
throughout their entire lifetime. In other words, if
you wish to rotate the wheels, make sure that the
same wheels are always on the same side of the
car.

NOTE: Please consult state or local regulations
restricting the use of studded winter tires before
installing such tires.

WARNING! Special wheel rims for air dams
Only special wheel rims, tested and approved
by Volvo, are suitable for use with the air dam
installed on the S90/V90.

*Where permitted.

Checking and correcting tire
pressure


Check the tire pressure when refueling.
The tire pressure should be corrected only when
the tires are cold. With warm tires, correct only
when the pressure is too low. The tire temperature
rises after driving just a few miles.



Vehicle Loading

The tires on your Volvo will perform to
specifications at all normal loads when inflated as

recommended on the tire information label*
located on the rear facing side on the right front
door. This label lists both tire and vehicle design
limits. Do not load your car beyond the load limits
indicated.

*Please note that the tire information label
indicates pressures for both comfort and fuel
economy.
Wheels and tires (cont.) pg. 75
Uniform tire quality grading

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

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 at 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 significantly from the norm due to
variation in driving habits, service 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 controlled
conditions on specified government test surfaces
of asphalt and concrete. A tire marked C may
have poor traction performance. TEMPERATURE
The temperature grades are AA (the highest), A,
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 level of performance
which all passenger car 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 established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.

WARNING! The traction grade assigned to
this tire is based on braking (straight-ahead)
traction tests and does not include cornering
(turning) traction.

Changing a wheel

On sedans the spare wheel, jack and toolbag are located in the trunk, be\
neath the carpet. The jack must be completely retracted to fit into the holder.

On wagons, the spare tire and the jack are located beneath the floor mat\
in the large storage bin. Always secure the spare tire and the jack to prevent them from rattling.

l Remove the wheel cap, using the screwdriver in the tool kit.
l With the car still on the ground, use the box wrench from the tool kit t\
o loosen the wheel nuts 1/2 - 1 turn. Turn the nuts counterclockwise to loosen.

NOTE:
To avoid excessive wear and the necessity of rebalancing, mark and reins\
tall wheels in same location and position as before removal. To lessen the chance of imbalance, each
wheel hub is equipped with a guide stud to ensure that a removed wheel c\
an be reinstalled in its original position (as when changing over to winter tires/wheels).
Wheel changing (cont.) pg. 79


WARNING!
l The jack attachment must engage the bar in the jack attachment (A). Th\
e car's weight must not rest on the jack's attachment (B).
l Be sure the jack is on a firm, level, non-slippery surface.
l Never allow any part of your body to be extended under a car supported b\
y a jack.
l Use the jack intended for the car when replacing a wheel. For any other \
job, use stands to support the end of the car being worked
on.
l Apply the parking brake, select position P (automatic transmission). \
l Block the wheels standing on the ground. Use rigid wooden blocks or larg\
e stones.
l The jack should be kept well-greased.

Attaching the jack

There is a jack attachment adjacent
to each wheel location. Position the
jack on the bar in the jack
attachment as shown in the
illustration above and crank while
simultaneously guiding the base to
the ground. The base of the jack
must be flat on a level, firm, non-
slippery surface. Before raising the
car check that the jack is still
correctly positioned in the
attachment. Now raise the vehicle
until the wheel is free of the ground.
Unscrew the wheel nuts completely
and carefully remove the wheel so
as not to damage the tread of the
studs. Installing the wheel

Clean the contact surfaces on the wheel and hub. Lift the wheel and plac\
e it on the hub. Make sure that you align the wheel
with the guide stud on the wheel hub prior to installation. Install the \
wheel nuts crosswise and tighten lightly. The conical
side of the nuts should face the wheel. Lower the vehicle to the ground \
and alternately tighten the nuts to 63 ft. lbs. (85 Nm).
Install the wheel cap.

Correct tightening order for wheel nuts
Spare tire pg. 80
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire othe\
r than as a
temporary replacement for a punctured tire. In other words, it must be r\
eplaced as
soon as possible by a standard tire. Roadholding, etc., may be affected \
with the
"Temporary Spare" in use. Do not, therefore, exceed 50 mph (80 km/h). \
Temporary Spare (certain models)

The spare tire of your car is what is called a "Temporary Spare".
Recommended tire pressure (see decal) should be maintained irrespectiv\
e of which
position on the car the Temporary Spare tire is used on. In the event of\
damage to this
tire a new one can be purchased from your Volvo retailer.
