•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.

Wheel nuts

199 Wheel nuts
Low nut
High nut
Lockable wheel nuts
Three different types of wheel nuts may be
used on your vehicle, depending on whether
the wheels are steel or aluminum.
Tightening torques:
•Type 1 wheel nuts: 81 ft. lbs. (110 Nm)
•Type 2 wheel nuts: 96 ft. lbs. (130 Nm)
•Type 3 Lockable wheel nuts: 81 ft. lbs.
(110 Nm)
Steel rims – type 1 wheel nutsSteel rims are normally secured using type 1
wheel nuts, although these rims may also be
secured with type 2 nuts.
WARNING
Never use type 1 wheel nuts for aluminum
wheels. This could cause the wheel to come
loose.
Aluminum wheels – type 2 wheel nutsOnly type 2 wheel nuts can be used for alumi-
num wheels.
NOTE
These nuts can also be used on steel
wheels.
Lockable wheel nut (3)If steel wheels with lockable wheel nuts are
used in combination with wheel covers, the
lockable wheel nut must be fitted to the stud
nearest the air valve. The wheel cover cannot
otherwise be installed on the wheel.

Tire Pressure Monitoring System (TPMS)

204* Option/accessory, for more information, see Introduction.
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.
