Wheels and tires
The handling and riding comfort of the vehicle is dependent on the inflation pressure and the type of tires fitted. Read

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.

Wear indicator
The tires have a so-called "wear indicator" in the form of a number of narrow strips running across or parallel to the
tread. When approx. 1/16" (1.6 mm) is left on the tread, these strips show up and indicate that the tire should be
replaced.
Tires with less than 1/16" (1.6 mm) tread have a very poor grip in rain or snow.
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. See the tire pressure label on the inside of the fuel tank cover.
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.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a tendency to distort
slightly, forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however, disappear when the tire warms up. The degree to which the flat spots form depends on the type of
cord used in the tire. Remember that, in cold weather, it takes longer for the tire to warm up and consequently longer
for the flat spot to disappear. 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. *
* This also applies to models equipped with All Wheel Drive (AWD). pg. 87 Wheels and tires (cont.)
Snow chains
Snow tire chains can be used on your Volvo with the following restrictions:
ProCarManuals.com

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
