inflation pressure VOLVO XC90 2007 User Guide

2007 Volvo XC90
- Drive the vehicle 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.
Changing wheels with TPMS
Please note the following when changing or replacing the factory install\
ed TPMS wheels/ tires on the
vehicle:
l Only the factory-mounted wheels are equipped with TPMS sensors in the va\
lves.
l If the vehicle is equipped with a temporary spare tire, this tire does n\
ot have a TPMS sensor.
l If wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SY\
ST SERVICE
REQUIRED will be displayed each time the vehicle is driven above 25 mph \
(40 km/h) for 10 minutes or
more.
l Once TPMS sensors are properly installed, the warning message should not\
reappear.
l Volvo recommends that TPMS sensors be fitted on all wheels used on the v\
ehicle. 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 strai\
ght onto the valve to help
avoid bending or otherwise damaging the valve.
Adjusting (recalibrating) TPMS
1
TPMS can be adjusted, or recalibrated, in order to help adapt the system\
to different inflation pressures,
for example when transporting heavy loads. To do so:
- Switch off the engine.
- Inflate the tires to the desired pressure.
- Turn the ignition key to position I or II.
- Turn the thumbwheel on the left steering wheel lever until the text TI\
RE PRESSURE CALIBRATION
is displayed.
- Press in and hold the Reset button (see the illustration on
page 50) until TIRE PRESSURE
CALIBRATED is displayed. This completes the procedure.
NOTE: TPMS should be recalibrated each time tire inflation pressure is change\

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 163 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.
Tire suppliers may have additional markings, notes or warnings such as s\
tandard load, radial tubeless,
etc.

Glossary of tire terminology
l Tire information placard: A placard showing the OE (Original Equipment) tire sizes, recommende\
d
inflation pressure, and the maximum weight the vehicle can carry.
l Tire Identification Number (TIN): A number on the sidewall of each tire providing information
about the tire brand and manufacturing plant, tire size and date of manu\
facturer.
l Inflation pressure: A measure of the amount of air in a tire.
l Standard load: A class of P-metric or Metric tires designed to carry a maximum load a\
t 35 psi [37
psi (2.5 bar) for Metric tires]. Increasing the inflation pressure bey\
ond this pressure will not increase the
tires load carrying capability.
l Extra load: A class of P-metric or Metric tires designed to carry a heavier maximu\
m load at 41 psi
[43 psi (2.9 bar) for Metric tires]. Increasing the inflation pressure\
beyond this pressure will not increase
the tires load carrying capability.
l kPa: Kilopascal, a metric unit of air pressure.
l PSI: Pounds per square inch, a standard unit of air pressure.
l B-pillar: The structural member at the side of the vehicle behind the front door\
.
l Bead area of the tire: Area of the tire next to the rim.
l Sidewall of the tire: Area between the bead area and the tread.
l Tread area of the tire: Area of the perimeter of the tire that contacts the road when mounted \
on the
vehicle.
l Rim: The metal support (wheel) for a tire or a tire and tube assembly upo\
n which the tire beads are
seated.
l 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\
.
l 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.
l 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 inf\
lation pressure is affected by the
number of occupants in the vehicle, the amount of cargo, and the speed a\
t 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 C\
anadian models, and in the tire
inflation table in this chapter.
l Cold tires: The tires are considered to be cold when they have the same temperatur\
e as the
surrounding (ambient) air. This temperature is normally reached after \
the vehicle has been parked for at
least 3 hours.
