155 Tread wear indicator
G020323
Tread wear indicatorThe 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 trac-
tion.
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 altera-
tion of the driving characteristics of the vehicle.
New tires
Remember that tires are per-
ishable 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 ageTires degrade over time, even when they are
not being used. It is recommended that tires
generally be replaced after 6 years of normal
service. Heat caused by hot climates, frequent
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 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 tables on pages 158 and 159.
•
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.

Tire inflation placards on U.S. modelsCheck tire inflation pressure regularly.
Tables listing the recommended inflation pres-
sure for your vehicle can be found on pages
158 and 159. A tire inflation pressure placard
is 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). This plac-
ard indicates the designation of the factory-
mounted tires on your vehicle, as well as load
limits and inflation pressure.

Tire inflation placard on Canadian models
NOTE
The placards shown indicate inflation pres-
sure for the tires installed on the vehicle 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 pres-
sure gauge, as automatic service station
gauges may be inaccurate.
•
Use the recommended cold inflation pres-
sure for optimum tire performance and
wear.
•
Under-inflation or over-inflation may cause
uneven treadwear patterns.WARNING
Under-inflation is the most common cause
of tire failure and may result in severe tire
cracking, tread separation, or "blowout,"
with unexpected loss of vehicle control and
increased risk of injury.
Under-inflated tires reduce the load carrying
capacity of your vehicle.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 certifi-
cation label.Checking tire pressureA certain amount of air seepage from the tires
occurs naturally and tire pressure fluctuates
with seasonal changes in temperature. Always
check tire pressure regularly.Cold tiresInflation 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
vehicle has been parked for at least 3 hours.
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 pres-
sure 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 pres-
sures 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, includ-
ing 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 irregular-
ities.
NOTE
If you overfill the tire, release air by pushing
on the metal stem in the center of the valve.
Then recheck the pressure with your tire
gauge.
Some spare tires require higher inflation
pressure than the other tires. Consult the
tire inflation tables on pages 158 and 159,
or see the inflation pressure placard.

Temporary spare

167
The spare tire in your vehicle is called a "Tem-
porary Spare".
Recommended tire pressure (see the placard
on the B-pillar or on the fuel filler door) should
be maintained irrespective of which position on
the vehicle the temporary spare tire is used on.
In the event of damage to this tire, a new one
can be purchased from your Volvo retailer.
WARNING
Current legislation prohibits the use of the
"Temporary Spare" tire other than as a tem-
porary replacement for a punctured tire. It
must be replaced as soon as possible 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).
CAUTION
The vehicle must not be driven with wheels
of different dimensions or with a spare tire
other than the one that came with the vehi-
cle. The use of different size wheels can
seriously damage your vehicle's transmis-
sion.
