1994 CHEVROLET ASTRO PASSENGER tires

Downloaded from www.Manualslib.com manuals search engine Temperature - A, By C
The temperature grades are A (the highest), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laborat\
ory test
wheel. Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade
C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard
No. 109. Grades B and A represent higher levels of
performance
on the laboratory test wheel than the minimum required by
law.
Warning: The temperature grade
for this tire is established for a tire that is
properly inflated and
not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination, can cause heat
buildup and possible tire failure.
These grades are molded on the sidewalls
of passenger car tires.
While the tires available as standard or optional equipment on General
Motors vehicles may vary with respect to these grades, all suc\
h tires meet General Motors performance standards and have been approved for use
on
General Motors vehicles. All passenger type (P Metric) tires must conform
to Federal safety requirements
in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully at \
the
factory to give you the longest tire life and best overall performance.
In most cases, you will not need to have your wheels aligned again.
However, if you notice unusual tire wear or your vehicle pulling
one way or
the other, the alignment may need
to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels may need \
to be
rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts, and wheel
nuts should be replaced. If
the wheel leaks air, replace it (except some aluminum wheels, \
which can
sometimes be repaired). See your
GM dealer if any of these conditions exist.
Your dealer will know the kind of wheel
you need.

NOTICE:
If your vehicle has P245/60R15 size tires, don’t use tire chains;
they can damage your vehicle.
If you have other size tires, use tire chains only where legal and
only when you must. Use only
SAE Class “S” type chains that
are the proper size for your tires. Install them on the rear axle
tires and tighten them
as tightly as possible with the ends
securely fastened. Drive slowly and follow the chain
manufacturer’s instructions. If you can hear the chains
contacting your vehicle, stop and retighten them.
If the contact
continues, slow down until it stops. Driving too fast with chains
on will damage your vehicle.
Appearance Care
P
Remember, cleaning products can be hazardous. Some are toxic. Others can
burst into flame if you strike a match or get them on a hot part
of the
vehicle. Some are dangerous if
you breathe their fumes in a closed space.
When you use anything from
a container to clean your vehicle, be sure to
follow the manufacturer’s warnings and instructions. And alway\
s open your
doors or windows when you’re cleaning the inside.

proper wear and maximum tire life, rotate tires at the first
6,000 miles
(10
000 kilometers) for Schedule I or 7,500 miles (12 500 kilometers)
for Schedule I1 and
then every 15,000 miles (25 000 kilometers)
thereafter. Follow the instructions and patterns shown in Sectio\
n
6.
Check tires for uneven wear or damage. If irregular or premature wear
is apparent, check wheel alignment. Also, check for damaged wheels.
See “Tires” in the Index for more information.
14.
DRIVE AXLE SERVICE - Check readfront axle fluid level and add
as needed. Check constant velocity joints and axle seals for leaking.
Locking Differential - Drain fluid at first oil change and refill.
Check fluid level and add as needed at subsequent oil changes. In
dusty areas or trailer towing applications, drain fluid at every
15,000 miles (24 135 kilometers) and refill.?
Standard Differential - Check fluid level and add as needed at
every oil change. In dusty areas or trailer towing applications\
,
drain fluid every
15,000 miles (24 135 kilometers) and refill.?
15. BRAKE SYSTEM INSPECTION - When the engine oil is changed,
inspect the lines and hoses for proper hookup, binding, leaks, cracks,
chafing, etc. Check the parking brake adjustment, and the fluid\
level in the master cylinder. A low fluid level can indicate
worn disc brake pads
which may need to be serviced.?
When the wheels are removed for rotation, inspect disc brake pads for
wear and rotors for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including drums, wh\
eel
cylinders, parking brake, etc. at the same time.
Inspect brakes more often if driving habits or conditions resul\
t in
frequent braking.
-f A fluid loss in these systems may indicate a problem. Have them inspected a\
nd
repaired at once.
