covered roads, we recommend suitable winter tires on all four wheels.
When replacing tires, be sure that the new tires are the same size designation, type (radial) and preferably from the
same manufacturer, on all four wheels. Otherwise there is a risk of altering the car's roadholding and handling
characteristics.
Storing wheels and tires
When 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.
Unapproved wheel/tire size combinations can negatively affect your vehicle's stability and handling. Approved tire
sizes are shown in the Tire inflation pressure tables on pages 172 and 173
.
Any damage caused by installation of unapproved wheel/tire size combinations will not be covered by your new
vehicle warranty. Volvo assumes no responsibility for death, injury, or expenses that may result from such
installations.
Tread wear indicator
The tires have wear indicator strips running across or parallel to the tread. 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 prevent alteration of the driving characteristics of the
vehicle.

General information
ProCarManuals.com
Do not mix tires of different design as this could also negatively affect overall tire road grip.
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 tires should have the same rotational
direction throughout their entire lifetime.
NOTE
Please consult state or provincial regulations restricting the use of studded winter tires before installing such tires.

Wheel nuts
Wheel nuts
There are two different types of wheel nut, depending on whether the wheels are steel or aluminum.
Steel rims - low nut
Steel rims are normally secured using the low type of nut, although steel rims may also use the high type.
WARNING
Never use the short type of nut for aluminium wheels. This could cause the wheel to come loose.
Aluminum wheels - high nut
Only the high type of nut can be used for aluminum wheels. This is considerably different from other types of nut
because it has a rotating conical thrust washer.
NOTE
This nut can also be used on steel wheels.
Lockable wheel nut
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.
