General information

Your vehicle is equipped with tires according
to the tire information label located on the rear
facing side of the right front door.
The following is an example of a tire designation
code:
195 = tire width in mm.
60 = tire profile. This is the relationship (in
percent) between the section height and the width
of the tire.
R= radial tires.
15 = diameter in inches on all four wheels.
The tires have good road holding characteristics
and offer good handling on dry and wet surfaces.
Your Volvo may be equipped with "all-season"
tires, which provide a somewhat higher degree
of winter roadholding 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.

Chapter 5 - Wheels and tires

Snow chains, Winter tires
Inflation pressure
Uniform tire quality grading
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.
To improve tire economy:
Maintain correct tire pressure.
Drive smoothly: avoid fast starts, hard braking
and tire screeching.
Tire wear increases with speed.
Correct front wheel alignment is very
important. Unbalanced wheels impair tire
economy and driving comfort.
If the wheels are rotated, they should be kept on
the same side of the car so that they revolve in the
same direction as prior to rotation.
Hitting curbs or potholes can damage the tires
and/or wheels permanently.
