General information
Your vehicle is equipped with tires according to the tire information label on the inside of the fuel filler door.
The following is an example of a tire designation code: 225/55 R16
225 = tire width in mm.
55 = tire profile. This is the relationship (in percent) between the section height and width of the tire.
R = radial tires.
16 = 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 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
dimensions, type (radial) and preferably from the same manufacturer, on all four wheels. Do not use bias ply tires.
Otherwise there is a risk of altering the car's roadholding and handling characteristics.
NOTE: When storing wheel/tire assemblies (e.g. snow 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 wear indicator strips running across or parallel to the tread. When approx. 1/16" (1.6 mm) is left on the
tread, these strips become visible and indicate that the tire should be replaced.
ProCarManuals.com
Tires with less than 1/16" (1.6 mm) tread have very poor grip in rain or snow.
To improve tire economy:
Maintain correct tire pressure. See the tire pressure label on the inside of the fuel filler door.
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.
Volvo does not recommend rotating the tires. However, if tires are rotated, they must be kept on the same side of the
car so that they revolve in the same direction as before 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 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/specifications 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 or
driveline.
pg. 109 Wheels and tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
Snow chains should be installed on front wheels only. Use only Volvo approved snow chains.
Special snow chains must be mounted on 215/55 R16. 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. Sufficient clearances between chains and brakes, suspension and
body components must be maintained. Snow chains cannot be used on 17" wheels.
Some strap -on type chains will interfere with brake components and therefore CANNOT be used.
All Wheel Drive models: Snow chains should only be installed on the front wheels. Only chains adapted for AWD
models should 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 chain manufacturer's installation instructions carefully. Install chains as tightly as possible and
retighten periodically.
Never exceed the chain manufacturer's specified maximum speed limit. In no case should you exceed 31 mph (50
km/h).
Avoid bumps, holes or sharp turns when driving with snow chains.
Vehicle handling can be adversely affected when driving with chains. Avoid fast maneuvering and hard braking.
