WHEELS AND TIRES

sidewall (see the illustration). A tire with e.g., visi-
ble cracks or discoloration should be replaced
immediately.
Tire economy
•
Maintain correct tire pressure.
•
Avoid fast starts, hard braking and tire
screeching.
•
Tire wear increases with speed.
•
Correct front wheel alignment is very impor-
tant.
•
Unbalanced wheels impair tire economy and
driving comfort.
•
Tires must maintain the same direction of
rotation throughout their lifetime.
•
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.
•
Hitting curbs or potholes can damage the
tires and/or wheels permanently.
Tire rotation
Your vehicle has no required tire rotation. Tire
wear is affected by a number of factors such as
tire inflation, ambient temperature, driving style,
etc.
NOTE
•
If the tires are rotated, they should only
be moved from front to rear or vice versa.
They should never be rotated left to
right/right to left.
•
Ideally, tire rotation should be done the
first time after approximately 3,000 miles
(5,000 km) and thereafter at 6,000-mile
(10,000-km) intervals. Some customers
find that tire rotation may help to get
extra mileage from tire life.
•
Tire rotation should only be performed if
front/rear tire wear is fairly even and
tread height is above 1/16" (1.6 mm).
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 nega-
tively affect your vehicle's stability and
handling.
•
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.
