08 Wheels and tires
General information

Introduction
Your vehicle is equipped with tires according
to the vehicle's tire information placard on the
B-pillar (the structural member at the side of
the vehicle, at the rear of the driver's door
opening).
CAUTION
Some Volvo models are equipped with an
Ultra High Performance tire and wheel
combination designed to provide maxi-
mum dry pavement performance with con-
sideration for hydroplaning resistance.
They may be more susceptible to road
hazard damage and, depending on driving
conditions, may achieve a tread life of less
than 20,000 miles (30,000 km). Even if this
vehicle is equipped with Volvo’s advanced
AWD or DSTC system, these tires are not
designed for winter driving, and should be
replaced with winter tires when weather
conditions dictate.
The tires have good road holding characteris-
tics and offer good handling on dry and wet
surfaces. It should be noted however that the
tires have been developed to give these fea-
tures on snow/ice-free surfaces.
Most models are equipped with "all-season"
tires, which provide a somewhat higher
degree of road holding on slippery surfaces
than tires without the "all-season" rating.
However, for optimum road holding on icy or
snow-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 manu-
facturer, on all four wheels. Otherwise there is
a risk of altering the car's roadholding and
handling characteristics.
New Tires
Remember that tires are perishable goods. As
of 2000, the manufacturing week and year
(Department of Transportation (DOT) stamp)
will be indicated with 4 digits (e.g., 1513
means that the tire illustrated was manufac-
tured during week 15 of 2013).
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 rota-
ted 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).
Tire age
Tires degrade over time, even when they are
not being used. It is recommended that tires
generally be replaced after 6 years of normal
service. Heat caused by hot climates, fre-
quent high loading conditions or Ultra Violet
(U.V.) exposure can accelerate the aging
