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 195/60R15:
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.
The tires have good road holding characteristics and offer good handling on dry and wet surfaces. It should be noted
however that the tires have been developed to give these features on snow/ice-free surfaces. Certain models are
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 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 road-holding and handling characteristics .
NOTE: When storing wheel/tire assemblies (e.g. winter tires and wheels), either stand the assemblies upright or
suspend them off the ground. Laying wheel/tire assemblies on their sides for prolonged periods can cause wheel and/or
tire damage.

Snow chains should be installed on front wheels only (this applies to cars with front wheel drive and to cars
equipped with All Wheel Drive) . Use only Volvo approved snow chains.
Snow chains may be mounted on tire dimension
Front wheel drive: 185/65R15 and 195/60R15. Tire dimension 205/55R15 and 205/50R16 require a special type of
snow chain.
Chains cannot be used on front wheel drive models equipped with 205/55R16 tires.
All Wheel Drive: Special snow chains are available for AWD models equipped with 195/65R15 and 205/55R16 tires.
Chains cannot be used on V70 XC AWD models equipped with 205/65R15 tires. Consult your Volvo retailer.
If accessory, aftermarket or "custom" tires and wheels are installed and are of a size different than the original
tires and wheels, chains in some cases CANNOT be used. Snow chains cannot be used on those turbo-charged
models fitted with all-season tires 205/55 R16. Models equipped with 205/55 R15 or 205/50 R16 need specially
designed snow chains. Sufficient clearances between chains and brakes, suspension and body components must
be maintained.
Some strap-on type chains will interfere with brake components and therefore CANNOT be used.
Consult your Volvo retailer for additional snow chain information. CAUTION:
Check local regulations regarding the use of snow chains before installing.
Always follow the chains manufacturer's installation instructions carefully. Install chains as tightly as possible and
re-tighten periodically.
Never exceed the chain manufacture's specified maximum speed limit. (Under no circumstances should that limit
be higher than 30 mph (45 km/h).
Avoid bumps, holes or sharp turns when driving with snow chains.
The handling of the vehicle can be adversely affected when driving with chains. Avoid fast or sharp turns as well
as locked wheel braking.
Snow tires, studded tires *
Tires for winter use:
Owners who live in or regularly commute through areas with sustained periods of snow or icy driving
conditions are strongly advised to fit suitable winter tires to help retain the highest degree of traction.
It is important to install winter tires on all four wheels to help retain traction during cornering, braking and
accelerating. Failure to do so could reduce traction to an unsafe level or adversely affect handling. Do not mix tires of
different design as this could also negatively affect overall tire road grip. Volvo recommends 185/65 R15 winter tires
on 15" wheels on all front wheel drive S/V 70 models** including models equipped with 16" or 17" wheels.
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 car tires should have the same rotational

direction throughout theirentire lifetime. In other words, if you wish to rotate the wheels, make sure that the same
wheels are always on the same side of the car.
NOTE: Please consult state or provincial regulations restricting the use of studded winter tires before installing such
tires.
* Where permitted
** All Wheel Drive models, including the AWD XC should be equipped with 195/65 R15 winter tirespg. 88 Wheels and tires (cont.)
Checking and correcting tire pressure
Check the tire pressure when refueling.
The tire pressure should be corrected only when the tires are cold.
With warm tires, correct only when the pressure is too low. The tire temperature rises after driving just a few miles.
Vehicle Loading
The tires on your Volvo will perform to specifications at all normal loads when inflated as recommended on the tire
information label* located on the inside of the fuel filler flap. This label lists both the tire and vehicle design limits.
Do not load your car beyond the load limits indicated.
* Please note that the tire information label indicates pressures for both comfort and fuel economy.

With the car still on the ground, use the lug wrench to loosen the wheel bolts 1/2 - 1 turn. Turn the bolts
counterclockwise to loosen.
Fold out the crank handle on the jack by pressing the nob on the handle downward. To attach the jack, refer to the
illustration on the following page.
NOTE: To avoid excessive wear and the necessity of rebalancing, mark and reinstall wheels in same location and
position as before removal. To lessen the chance of imbalance, each wheel hub is equipped with a guide stud to ensure
that a removed wheel can be reinstalled in its original position (as when changing over to winter tires/wheels).
CAUTION:
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came
with the car. The use of different size wheels can seriously damage your car's transmission.
Correct tightening torque on wheel bolts must be observed. The wheel bolts must be observed. The wheel bolts
should never be greased or lubricated. The extended, chromed wheel bolts must not be used with steel rims, as they
make it impossible to fit the hub caps.
WARNING!
The jack (see the following page) must engage the bar in the jack attachment (A). The car's weight must not rest on
the jack's attachment (B).
Be sure the jack is on a firm, level, non-slippery surface.
Never allow any part of your body to be extended under a car supported by a jack.
Use the jack intended for the car when replacing a wheel. For any other job, use stands to support the end of the
car being worked on.
Apply the parking brake, select position P (automatic transmission) or Reverse gear (manual transmission).
Block the wheels standing on the ground, use rigid wooden blocks or large stones.
The jack should be kept well-greased.
