tire size VOLVO XC70 2007 Owners Manual

2007 Volvo XC70
Volvo recommends that you always drive on tires of the same brand, size,\
construction (radial), tread
pattern, load-, speed-, traction- , temperature-, and treadwear rating. \
Never drive on mixed tires, except
for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and \
inflation pressures are shown on
the tire inflation pressure placards, located on the driver's side B-pil\
lar (the structural member at the side
of the vehicle, at the rear of the driver's door opening), or on the in\
side of the fuel filler door on
Canadian models.
Temporary Spare
The temporary spare tire is for temporary, low-speed, short-distance use\
only. Replace it with a full-
sized tire as soon as possible. Do not drive on the temporary spare at s\
peeds above 50 mph (80km/h) or
for distances greater than 50 miles (80 km).
Never install snow chains on a temporary spare.

Four-C active chassis system
Four-C active chassis
The FOUR-C (Continuously Controlled Chassis Concept) active chassis sy\
stem, consisting of Comfort
and Sport modes, is available as an option.
NOTE: The V70 R has a standard FOUR-C system consisting of Comfort, Sport, an\
d Advanced sport
modes. The buttons for controlling these driving modes are located in ce\
nter instrument panel, above the
ventilation system panel vents, see the illustration in the right column\
. These buttons can be pressed at
any time to change driving modes. An indicator light in the selected but\
ton will come on to indicate the
driving mode that is currently selected.
This system is based on a number of sensors that continuously monitor fa\
ctors such as the vehicle's
lateral and vertical movements, speed, and movements of the wheels. The \
sensors receive data up to 500
times per second, which is used to provide extremely fast and precise ad\
justment of each shock
absorber. The system adjusts the stiffness of the shock absorbers approx\
imately 100 times per second

Use the button in the center console to switch between the driving modes\
Comfort and Sport. This can
be done at any time.
Comfort
The Comfort mode chassis setting offers the greatest amount of shock abs\
orption and the softest ride.

surfaces.
Certain models are equipped with "all-season" tires, which provide a som\
ewhat 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 desig\
nation, type (radial) and
preferably from the same manufacturer, on all four wheels. Otherwise the\
re is a risk of altering the
vehicle's roadholding and handling characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be s\
uspended off the floor or placed
on their sides on the floor.
Tires not mounted on rims should be stored on their sides or standing up\
right, 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.
Tread wear indicator
The tires have wear indicator strips running across or parallel to the t\
read. 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.

General information
WARNING!
l The wheel and tire sizes for your Volvo are specified to meet stringent \
stability and handling
requirements. Unapproved wheel/tire size combinations can negatively aff\
ect your vehicle's stability
and handling. Approved tire sizes are shown in the Tire inflation pressu\
re tables on
pages 160 and
161.
l Any damage caused by installation of unapproved wheel/tire size combinat\
ions will not be covered
by your new vehicle warranty. Volvo assumes no responsibility for death,\
injury, or expenses that
may result from such installations.
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).
Tire age
Tires degrade over time, even when they are not being used. It is recomm\
ended that tires generally be
replaced after 6 years of normal service. Heat caused by hot climates, f\
requent high loading conditions
or Ultra Violet (U.V) exposure can accelerate the aging process.
You should replace the spare tire when you replace the other road tires \
due to the aging of the spare.
A tire's age can be determined by the DOT stamp on the sidewall (see th\
e illustration above).
A tire with e.g., visible cracks or discoloration should be replaced imm\
ediately.
Improving tire economy:
l Maintain correct tire pressure. See the tire pressure table on pages 160 and 161.
l Drive smoothly: avoid fast starts, hard braking and tire screeching.
l Tire wear increases with speed.
l Correct front wheel alignment is very important.
l Unbalanced wheels impair tire economy and driving comfort.

Inflation pressure
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 vehicle has been parked f\
or at least 3 hours.
After driving a distance of approximately 1 mile (1.6 km), the tires a\
re considered to be hot. If you have
to drive farther than this distance to pump your tire(s), check and re\
cord 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 col\
d pressures. A hot tire at or
below recommended cold inflation pressure could be significantly under-i\
nflated.
To check inflation pressure:
- Remove the cap from the valve on one tire, then firmly press the tire \
gauge onto the valve.
- Add air to reach the recommended air pressure.
- Replace the valve cap.
- Repeat this procedure for each tire, including the spare.
- Visually inspect the tires to make sure there are no nails or other ob\
jects embedded that could puncture
the tire and cause an air leak.
- Check the sidewalls to make sure there are no gouges, cuts, bulges or \
other irregularities.
NOTE:
l If you overfill the tire, release air by pushing on the metal stem in th\
e center of the valve. Then
recheck the pressure with your tire gauge.
l Some spare tires require higher inflation pressure than the other tires.\
Consult the tire inflation table
on
pages 160 and 161 or see the inflation pressure placard.

only
The tire pressure monitoring system uses sensors mounted in the tire val\
ves to check inflation pressure
levels. When the vehicle is moving at a speed of approximately 20 mph (\
30 km/h) or faster, these
sensors transmit inflation pressure data to a receiver located in the ve\
hicle.
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 dev\
ice must accept any interference
received, including interference that may cause undesired operation.
When low inflation pressure is detected, TPMS will light up the tire pre\
ssure warning light (
) (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 pressur\
e loss.
NOTE: If a fault occurs in TPMS, the tire pressure warning light will flash f\
or approximately 1 minute
and TIRE PRESS SYST SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided), should be checked monthl\
y when cold and inflated to the
inflation pressure recommended by the vehicle manufacturer on the vehicl\
e 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 determine the proper tire i\
nflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire p\
ressure monitoring system
(TPMS) that illuminates a low tire pressure telltale when one or more \
of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale illuminates, \
you should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driv\
ing 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 an\
d stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenanc\
e, and it is the driver's
responsibility to maintain correct tire pressure, even if under-inflatio\
n has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to\
indicate when the system is
not operating properly. The TPMS malfunction indicator is combined with \
the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for appro\
ximately one minute and then
remain continuously illuminated. This sequence will continue upon subseq\
uent vehicle start-ups as long
as the malfunction exists. When the malfunction indicator is illuminated\
, the system may not be able to
detect or signal low tire pressure as intended. TPMS malfunctions may oc\
cur for a variety of reasons,
including the installation of replacement or alternate tires or wheels o\
n the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction tellta\
le after replacing one or
more tires or wheels on your vehicle to ensure that the replacement or a\
lternate tires and wheels allow
the TPMS to continue to function properly.
NOTE:
l TPMS indicates low tire pressure but does not replace normal tire mainte\
nance. For information on
correct tire pressure, please refer to the tables on
pages 160 and 161, or consult your Volvo retailer.

Federal law mandates that tire manufacturers place standardized informat\
ion 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 desi\
gnation):
1. 215: the width of the tire (in millimeters) from sidewall edge to s\
idewall edge. The larger the number,
the wider the tire.
2. 65: The ratio of the tire's height to its width.
3. R: Radial tire.
4. 15: The diameter of the wheel rim (in inches).
5. 95: The tire's load index. In this example, a load index of 95 equals\
a maximum load of 1521 lbs (690
kg).
6. H: The tire's speed rating, or the maximum speed at which the tire is\
designed to be driven for
extended periods of time, carrying a permissible load for the vehicle, a\
nd with correct inflation pressure.
For example, H indicates a speed rating of 130 mph (210 km/h).
NOTE: This information may not appear on the tire because it is not required \
by law.
7. M+S or M/S = Mud and Snow, AT = All Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN): This begins with the let\
ters "DOT" and indicates that the
tire meets all federal standards. The next two numbers or letters are th\
e plant code where it was
manufactured, the next two are the tire size code and the last four numb\
ers represent the week and year
the tire was built. For example, the numbers 317 mean the 31st week of 1\
997. After 2000 the numbers
go to four digits. For example, 2501 means the 25th week of 2001. The nu\
mbers in between are

marketing codes used at the manufacturer's discretion. This information \
helps a tire manufacturer
identify a tire for safety recall purposes.
9. Tire Ply Composition and Material Used: Indicates the number of plies\
indicates or the number of
layers of rubber-coated fabric in the tire tread and sidewall. Tire manu\
facturers also must indicate the
ply materials in the tire and the sidewall, which include steel, nylon, \
polyester, and others.
10. Maximum Load: Indicates the maximum load in pounds and kilograms tha\
t can be carried by the
tire. Refer to the vehicle's tire information placard or the safety cert\
ification label, located on the B-Pillar
or the driver's door or on the inside of the fuel filler door on Canadia\
n models, for the correct tire
pressure for your vehicle.
11. Treadwear, Traction, and Temperature grades: See
page 169 for more information.
12. Maximum permissible inflation pressure: the greatest amount of air p\
ressure that should ever be put
in the tire. This limit is set by the tire manufacturer.

Snow chains, snow tires, studded tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
l Snow chains should be installed on front wheels only. Use only Volvo app\
roved snow chains.
l 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. Sufficie\
nt clearances between chains
and brakes, suspension and body components must be maintained.
l Some strap-on type chains will interfere with brake components and there\
fore CANNOT be used.
l All Wheel Drive models: Snow chains should only be installed on the fron\
t 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 instal\
ling. Always follow the chain
manufacturer's installation instructions carefully. Install chains as ti\
ghtly 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 wit\
h chains. Avoid fast or sharp
turns as well as locked wheel braking.

Tires for winter use:
l Owners who live in or regularly commute through areas with sustained per\
iods of snow or icy driving
conditions are strongly advised to fit suitable winter tires to help ret\
ain the highest degree of traction.
l It is important to install winter tires on all four wheels to help retai\
n traction during cornering,
braking, and accelerating. Failure to do so could reduce traction to an \
unsafe level or adversely affect
handling.
l Do not mix tires of different design as this could also negatively affec\
t overall tire road grip.
l Winter tires wear more quickly on dry roads in warm weather. They should\
be removed when the
winter driving season has ended.
l Studded tires should be run-in 300-600 miles (500-1000 km) during whic\
h the vehicle 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 lifeti\
me.

Temporary spare
The spare tire in your vehicle is called a "Temporary Spare".
Recommended tire pressure (see the placard on the B-pillar or on the fu\
el filler door) should be
maintained irrespective of which position on the vehicle the temporary s\
pare tire is used on.
In the event of damage to this tire, a new one can be purchased from you\
r Volvo retailer.
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire othe\
r than as a temporary
replacement for a punctured tire. It must be replaced as soon as possibl\
e by a standard tire. Road
holding and handling may be affected with the "Temporary Spare" in use. \
Do not exceed 50 mph (80
km/h). Do not drive farther than 50 miles (80 km) on a temporary spar\
e tire.
CAUTION!
The vehicle must not be driven with wheels of different dimensions or wi\
th a spare tire other than the
one that came with the vehicle. The use of different size wheels can ser\
iously damage your vehicle's
transmission.
