Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where
to obtain service, see
your Buick Warranty booklet for details.
Poorly maintained and improperly used tires
are dangerous.
Overloading your tires can cause
overheating
as a result of too much friction.
You could have an air-out and
a serious
accident. See “Loading Your Vehicle” in
the Index.
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be cut,
punctured or broken by a sudden impact
--
such as when you hit a pothole. Keep tires
at the recommended pressure.
Worn, old tires can cause accidents. If your
tread
is badly worn, or if your tires have
been damaged, replace them.

Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
inside
of the trunk lid, shows the correct inflation
pressures for your tires when they’re cold. “Cold”
means your vehicle has been sitting for at least three
hours or driven no more than
1 mile (1.6 km).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is
all right. It’s not. If your tires
don’t have enough air (underinflation), you can
get the following:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
NOTICE: (Continued) NOTICE:
(Continued)
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out
dirt
and moisture.

Tire Pressure Monitor System (If Equipped)
The tire pressure monitor system can alert you to a large
change in the pressure
of one tire. The system “learns”
the pressure at each tire throughout the operating speed
range of your vehicle. The system normally takes
between
45 and 90 minutes of driving to learn the tire
pressures. This time may be longer depending on your
individual driving habits. Learning need not be
accumulated during
a single trip. Once learned, the
system will remember the tire pressures until the system
is recalibrated.
After the system has learned tire pressures with properly
inflated tires, the LOW TIRE light will come on if the
pressure in
one tire becomes 12 psi (83 kPa) lower than
the other three tires. The tire pressure monitor system
won’t alert you if the pressure
in more than one tire is
low, if the system is not properly calibrated, or if the
vehicle
is moving faster than 70 mph (1 10 kdh).
The tire pressure monitor system detects differences
in tire rotation speeds that are caused by changes
in
tire pressure. The system can alert you about a low
tire
-- but it doesn’t replace normal tire maintenance.
See “Tires” in the Index. When the LOW
TIRE light comes
on, you should stop
as soon as you can and check all your tires for damage.
(If a tire is flat, see “If
a Tire Goes Flat” in the Index.)
Also check
the tire pressure in all four tires as soon as
you can. See “Inflation
- Tire Pressure” in the Index.
The light will come on and stay on
until you turn off the
ignition or press the
RESET button.
Don’t reset the tire pressure monitor system without first
correcting the cause of the problem and checking and
adjusting the pressure in all four tires. If you reset the
system when the tire pressures are incorrect, the tire
pressure monitor system will not work properly and may
not alert you when
a tire is low.
Any time
you adjust a tire’s pressure, rotate your tires,
or have one or more tires repaired or replaced, you’ll
need to reset (calibrate) the tire pressure monitor system.
You’ll also need to reset the system whenever you buy
new tires and whenever the vehicle’s battery has been
disconnected.
To reset (calibrate) the system,
turn the ignition switch
to
RUN. Then press and hold the RESET button for
about five seconds.
6-44
ProCarManuals.com

The red RESET button is
located inside your
instrument panel fuse block.
(It’s the first button in the
top row of the fuse block.)
The LOW TIRE light will come
on and flash three
times. Then it will go off. If the light doesn’t go off, see
your dealer for service.
The system completes the calibration process during driving.
The system normally takes
15 to 20 minutes of driving in
each of three speed ranges to “learn” tire pressures. The
speed ranges are 15 to 40 mph (25 to 65 km/h), 40 to
65 mph (65 to 105 km/h) and above 65 mph (105 km/h).
When learning is complete, the system will alert you after
2-8 minutes if a tire is 12 psi (83 kPa) different from the
other
three tires. Detection thresholds may be higher and
detection times may be longer on rough roads, curves and
at high speeds. The system
is not capable of detection at
speeds greater
than 70 mph (1 10 km/h).
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires
as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires”
and
“Wheel Replacement” later in this section for
more information.
The purpose
of regular rotation is to achieve more
uniform wear for
all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals.
6-45
ProCarManuals.com

When rotating your tires, always use the correct
rotation pattern shown here.
Don’t include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures
as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque”
in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after
a time. The wheel could come off and cause
an accident. When
you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or
a paper towel to do this; but be
sure to use a scraper or wire brush later,
if you
need to,
to get all the rust or dirt off. (See
“Changing a Flat, Tire” in the Index.)
When It’s Time for New Tires
11 One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only
1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are true:
0 You can see the indicators at three or more places
around the tire.
0 You can see cord or fabric showing through the
tire’s rubber.
0 The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
