07 Wheels and tires
General information

178
•The tires with the most tread should always
be at the rear (to reduce the risk of skid-
ding).
•Contact a Volvo workshop if you are
unsure about the tread depth.
Storing wheels and tiresWhen 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.
WARNING
•The wheel and tire sizes for your Volvo
are specified to meet stringent stability
and handling requirements. Unap-
proved wheel/tire size combinations
can negatively affect your vehicle's sta-
bility and handling.
•Any damage caused by installation of
unapproved wheel/tire size combina-
tions will not be covered by your new
vehicle warranty. Volvo assumes no
responsibility for death, injury, or
expenses that may result from such
installations.

Changing wheels

198
check that the jack is still correctly posi-
tioned in the attachment.
7. Raise the vehicle until the wheel to be
changed is lifted off the ground.
8. 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).
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 vehi-
cle's transmission.
•Correct tightening torque on wheel
bolts must be observed.
•The wheel bolts should never be
greased or lubricated.
•Extended, chromed wheel bolts must
not be used with steel rims, as they
make it impossible to fit the hub caps.
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
103 ft.lbs. (140 Nm).
5. Install the wheel cover (where applicable).
WARNING
•The jack must correctly engage the bar
in the jack attachment. The vehicle's
weight must not rest on the jack attach-
ment. See illustration "Attaching the
jack" on the previous page.
•Be sure the jack is on a firm, level, non-
slippery surface.
•Never allow any part of your body to be
extended under a vehicle supported by
a jack.
•Use the jack intended for the vehicle
when replacing a wheel. For any other
job, use stands to support the side of
the vehicle being worked on.
•Apply the parking brake and put the
gear selector in the (P)ark position.
•Block the wheels standing on the
ground, use rigid wooden blocks or
large stones.
•The jack should be kept well-greased
and clean, and should not be damaged.
•No objects should be placed between
the base of jack and the ground, or
between the jack and the attachment
bar on the vehicle.

Tire Pressure Monitoring System (TPMS)
07
202* Option/accessory, for more information, see Introduction.
Activating/deactivating TPMS (Canadian
models only)
1. Switch off the engine.
2.
Turn the ignition key to position I or II.
3.
Press and hold the Reset button on the
left-side steering wheel lever until
TIRE
PRESS SYST OFF is displayed.
Repeat steps 1-3 to turn TPMS on again.
Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as
optional equipment. The vehicle must be
equipped with the Tire Pressure Monitoring
System (TPMS) if tires of this type are installed.
Tires of this type have specially reinforced
sidewalls that make it possible to continue
driving to a limited extent even though the tire
has lost some or all of its inflation pressure.
These tires are mounted on special rims (nor-
mal tires can also be mounted on these rims).
If an SST tire loses inflation pressure, the yel-
low TPMS symbol illuminates in the instrument
panel and a text message is also displayed. If
this happens, reduce speed to not more than
50 mph (80 km/h). The tire should be replaced
as soon as possible.Drive carefully; it may be difficult to determine
which tire is damaged. To find the damaged
tire, check the inflation pressure in all four tires.
WARNING
•SST tires should only be mounted by
service technicians who are familiar
with tires of this type.
•SST tires may only be mounted on vehi-
cles equipped with TPMS.
•Do not drive faster than 50 mph
(80 km/h) if TPMS indicates that a tire
has lost inflation pressure.
•Do not drive farther than 50 miles
(80 km) before replacing a damaged
SST tire.
•Drive carefully and avoid e.g., hard
braking or fast turns.
•SST tires must be replaced if they are
damaged. A tire of this type cannot be
repaired.
