General information
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), or on the inside of the fuel filler door on
Canadian models.
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 size designation, type (radial) and preferably from the
same manufacturer, on all four wheels. Otherwise there is a risk of altering the car's roadholding and handling
characteristics.

Tread wear indicator
Tread wear indicator
The tires have wear indicator strips running across or parallel to the tread. The letters TWI are printed on the side of
the tire. When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire
should be replaced. Tires with less than 1/16" (1.6 mm) tread offer very poor traction.
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.
New tires
Remember that tires are perishable goods. As of 2000, the manufacturing week and year will be indicated with 4 digits
(e.g. 1502 means that the tire illustrated was manufactured during week 15 of 2002).
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be suspended off the floor or placed on their sides
on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should not be
suspended.
CAUTION!
Tires should preferably be stored in a cool, dry, dark place, and should never be stored in close proximity to solvents,
gasoline, oils, etc.
WARNING!
The wheel and tire sizes for your Volvo are specified to meet stringent stability and handling requirements.
Unapproved wheel/tire size combinations can negatively affect your vehicle's stability and handling. Approved tire
sizes are shown in the Tire inflation pressure tables on page 122
.
Any damage caused by installation of unapproved wheel/tire size combinations will not be covered by your new
vehicle warranty. Volvo assumes no responsibility for death, injury, or expenses that may result from such
installations.

run flat tires.
Tires of this type have specially reinforced sidewalls that make it possible to continue driving in the event of a drop in
inflation pressure. Tires of this type are mounted on special rims.
NOTE: Self supporting run flat tires are only available in conjunction with TPMS.
If a self supporting run flat tire should lose inflation pressure, the yellow TPMS warning symbol (
) in the instrument
panel lights up to alert the driver, and a message will be shown in the text window in the instrument panel.
If this occurs, reduce vehicle speed to a maximum of 50 mph (80 km/h). The vehicle can be driven approximately 50
miles (80 km), or somewhat farther if the vehicle is not heavily loaded. The tire should be replaced as soon as
possible.
Hard braking and sudden steering maneuvers should be avoided.
In certain cases, it may be difficult to see which self supporting run flat tire is defective. To determine which tire is
damaged, check the inflation pressure of all four tires.
WARNING!
• Only specially trained persons should mount self supporting run flat tires.
• If self supporting run flat tires are mounted, the vehicle must be equipped with a Tire Pressure Monitoring System.
• After a low pressure warning has been displayed, do not exceed 50 mph (80 km/h).
• Avoid severe cornering and hard braking, and minimize the distance traveled before replacing the self supporting
run flat tire.
• Self supporting run flat tires cannot be repaired. They must be replaced if damaged or punctured.

Tire designations
Federal law mandates that tire manufacturers place standardized information on the sidewall of all tires (see the
illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire designation):
1. 215: the width of the tire (in millimeters) from sidewall edge to sidewall edge. The larger the number, the wider the
tire.
ProCarManuals.com

• PSI: Pounds per square inch, a standard unit of air pressure.
• B-pillar: The structural member at the side of the vehicle behind the front door.
• Bead area of the tire: Area of the tire next to the rim.
• Sidewall of the tire: Area between the bead area and the tread.
• Tread area of the tire: Area of the perimeter of the tire that contacts the road when mounted on the vehicle.
• Rim: The metal support (wheel) for a tire or a tire and tube assembly upon which the tire beads are seated.
• Maximum load rating: a figure indicating the maximum load in pounds and kilograms that can be carried by the
tire. This rating is established by the tire manufacturer.
• Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire.
This limit is set by the tire manufacturer.
• Recommended tire inflation pressure: inflation pressure, established by Volvo, which is based on the type of tires
that are mounted on a vehicle at the factory. This inflation pressure is affected by the number of occupants in the car,
the amount of cargo, and the speed at which the vehicle will be driven for a prolonged period. This information can be
found on the tire inflation placard(s) located on the driver's side B-pillar or on the inside of the fuel filler door on
Canadian models, and in the tire inflation table in this chapter.
• Cold tires: The tires are considered to be cold when they have the same temperature as the surrounding (ambient)
air. This temperature is normally reached after the car has been parked for at least 3 hours.

Vehicle loading
Properly loading your vehicle will provide maximum return of vehicle design performance.
Before loading your vehicle, familiarize yourself with the following terms for deter-mining your vehicle's weight
ratings, with or without a trailer, from the vehicle's Federal/ Canadian Motor Vehicle Safety Standards
(FMVSS/CMVSS) label, and the vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does not include passengers,
cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing, trailer hitch tongue load
is also part of cargo weight.
NOTE: For trailer towing information, please refer to the section "Towing a trailer" on page 107
.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (front or rear). These numbers are shown on the
Federal/Canadian Motor Vehicle Safety Standards (FMVSS/ CMVSS) label. The total load on each axle must never
exceed its maximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
NOTE:
• The location of the various labels in your vehicle can be found on page 160
.
• A table listing important weight limits for your vehicle can be found on page 166
.
Steps for Determining Correct Load Limit
(1) Locate the statement "the combined weight of occupants and cargo should never exceed XXX pounds" on your
vehicle's placard.
(2) Determine the combined weight of the driver and passengers that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds.
(4) The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX"

passenger vehicle tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the minimum required by law.WARNING!
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and tire
failure.

Snow chains, snow tires, studded 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.
• 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.
• 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. (Under no circumstances should you exceed
31 mph (50 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.

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.
• 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 tires should have the same rotational
direction throughout their entire lifetime.
NOTE: Please consult state or provincial regulations restricting the use of studded winter tires before installing such
