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.
pg. 119 Wheels and tires
Tire age
ProCarManuals.com

Tires degrade over time, even when they are not being used, which can affect their reliability and roadholding
characteristics. Therefore, all tires older than 6 years (including the spare tire and winter tires) should be inspected by a
qualified technician, regardless of appearance or mileage. Heat caused by hot climates or frequent high loading
conditions can accelerate the aging process.
A tire's age can be determined by the DOT stamp on the sidewall (see the illustration above).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
Improving tire economy:
• Maintain correct tire pressure. See the tire pressure table on page 122
.
• 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.
• Tires must maintain the same direction of rotation throughout their lifetime.
• When replacing tires, the tires with the most tread should be mounted on the rear wheels to reduce the chance of
oversteer during hard braking.
Hitting curbs or potholes can damage the tires and/or wheels permanently.
pg. 120 Wheels and tires
Tire inflation
Check tire inflation pressure regularly.
A table listing the recommended inflation pressure for your vehicle can be found on page 122
. Tire inflation pressure
placards are also located on the driver's side 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. These placards indicate the
designation of the factory-mounted tires on your vehicle, as well as load limits and inflation pressure.
ProCarManuals.com

Tire inflation placard on Canadian models, 1. XC70, 2. V70
NOTE: The placards shown indicate inflation pressure for the tires installed on the car at the factory only.
• Use a tire gauge to check the tire inflation pressure, including the spare, at least once a month and before long trips.
You are strongly urged to buy a reliable tire pressure gauge, as automatic service station gauges may be inaccurate.
• Use the recommended cold inflation pressure for optimum tire performance and wear.
• Under-inflation or over-inflation may cause uneven treadwear patterns.
When weather temperature changes occur, tire inflation pressures also change. A 10-degree temperature drop causes a
corresponding drop of 1 psi (7 kPa) in inflation pressure. Check your tire pressures frequently and adjust them to the
proper pressure, which can be found on the vehicle's tire information placard or certification label.
Checking tire pressure
Cold tires
Inflation pressure should be checked when the tires are cold.
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.
pg. 121 Wheels and tires
After driving a distance of approximately 1 mile (1.6 km), the tires are considered to be hot. If you have to drive
farther than this distance to pump your tire(s), check and record the tire pressure first and add the appropriate air
pressure when you get to the pump.
If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tires are hot from driving and it
is normal for pressures to increase above recommended cold pressures. A hot tire at or below recommended cold
inflation pressure could be significantly under-inflated.
To check inflation pressure:
1. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve.
2. Add air to reach the recommended air pressure
3. Replace the valve cap.
4. Repeat this procedure for each tire, including the spare.
5. Visually inspect the tires to make sure there are no nails or other objects embedded that could puncture the tire and
cause an air leak.
6. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.
NOTE:
• If you overfill the tire, release air by pushing on the metal stem in the center of the valve. Then recheck the pressure
ProCarManuals.com

with your tire gauge.
• Some spare tires require higher inflation pressure than the other tires. Consult the tire inflation table on page 122 or
see the inflation pressure placard.

pg. 123 Wheels and tires
Tire Pressure Monitoring System (TPMS) - option on certain U.S. models only
The tire pressure monitoring system uses sensors mounted in the tire valves to check inflation pressure levels. When
the vehicle is moving at a speed of 20 mph (30 km/h) or faster, these sensors transmit inflation pressure data to a
receiver located in the vehicle.
USA - FCC ID: MRXTG315AM04
This device complies with part 15 of the FCC rules. Operation is subject to the following conditions: (1) This device
may not cause harmful interference, and (2) this device must accept any interference received, including interference
that may cause undesired operation.
WARNING!
The TPMS system uses a radio frequency of 315 MHz. Accessory electrical equipment using the same frequency
could interfere with TPMS and should not be installed in the vehicle. Please consult your Volvo retailer, a qualified
Volvo service technician, or the accessory equipment's supplier for further information.
When low inflation pressure is detected, TPMS will light up the tire pressure warning light (
) i (also referred to as a
telltale) in the instrument panel, and will display a message in the text window. The wording of this message is
determined by the degree of inflation pressure loss.
When the tire pressure monitoring system warning light is on, one or more of your tires is significantly under-inflated.
You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the
vehicle's tire information placard.
Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Each tire,
including the spare, should be checked monthly when cold and set to the recommended inflation pressure as specified
in the vehicle placard and owner's manual.
NOTE: If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and TIRE
PRESS SYST SERVICE REQUIRED will be displayed.
ProCarManuals.com

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should consult
the appropriate section of this owner's manual to determine the proper tire inflation pressure.) When the low tire
pressure telltale is illuminated, one or more of your tires is significantly underinflated. You should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes
the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability. Your vehicle has also been equipped with a TPMS malfunction
telltale to indicate when the system is not operating properly. When the malfunction telltale is illuminated, the system
may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of incompatible replacement tires on the vehicle. Always check the TPMS
malfunction telltale after replacing one or more tires on your vehicle to ensure that the replacement tires are
compatible with the TPMS.
NOTE: TPMS indicates low tire pressure but does not replace normal tire maintenance. For information on correct tire
pressure, please refer to the table on page 122
, or consult your Volvo retailer.
Erasing warning messages
When a low tire pressure warning message has been displayed, and the tire pressure warning light has come on:
1. Use a tire pressure gauge to check the inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard or the table on page 122
).
3. Drive the car for several minutes at a speed of 20 mph (30 km/h) or faster.
This will erase the warning text and the warning light will go out.
WARNING!
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of the vehicle.

pg. 124 Wheels and tires
Changing tires
Please note the following when changing or replacing the factory installed TPMS wheels/ tires on the vehicle:
Only the factory-mounted wheels are equipped with TPMS sensors in the valves.
If the vehicle is equipped with a temporary spare tire, this tire does not have a TPMS sensor.
If winter wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SYST SERVICE REQUIRED will
be displayed each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes or more.
Once TPMS sensors are properly installed, the warning message should not reappear.
Volvo recommends that TPMS sensors be fitted on all wheels used on the vehicle. Volvo does not recommend
moving sensors back and forth between sets of wheels.
CAUTION!
When inflating tires with TPMS valves, press the pump's mouthpiece straight onto the valve to help avoid bending or
otherwise damaging the valve.
pg. 125 Wheels and tires
Self supporting run flat tires (option)
Certain models equipped with the Tire Pressure Monitoring System (TPMS) can also be equipped with self supporting
ProCarManuals.com

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.
