ESP CHEVROLET LUMINA 1993 1.G Owner's Manual

Downloaded from www.Manualslib.com manuals search engine 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. Simply looking
at
the tires will not tell you the pressure,
especially
if you have radial tires-
which may look properly inflated even
if
they're underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See the
Index
under Scheduled Maintenance
Services.
Use this rotation pattern.
Mer the tires have been rotated, adjust
the front and rear inflation pressure as
shown on the Tire-Loading Information
label. Make certain that
all wheel nuts
are properly tightened. See the
Index
under Wheel Nut Torque.
I
Rust or dirt on a wheel, or on
the parts to which it is
fastened, can make the 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
the
Index under Changing a Flat
Tire.)

Grading
The following information relates to the
system developed by the United States
National Highway Traffic Safety
Administration which grades tires by
treadwear, traction and temperature
performance. (This applies only to
vehicles sold in the United States.)
The treadwear grade is
a comparative
rating based on the wear rate
of the tire
when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and a half (1%)
times as well on the government course
as a tire graded
100. The relative
performance
of tires depends upon the
Treadwear
actual conditions of their use, however,
and may depart significantly
from the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction-A, B, C
The traction grades, from highest to
lowest are: A,
B, and C. They represent
the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked
C may have poor traction
performance.
Warning: The traction grade assigned
to this tire is based on braking (straight-
ahead) traction tests and does not
include cornering (turning) traction.
Temperature-A, B, 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
laboratory 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.

Temperature-A, B, C (CONT.)
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.
Those 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 such 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 ycur 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
I
coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If
the wheel leaks air out, replace
it
(except some aluminum wheels, which
can sometimes be repaired). See your
Chevrolet dealer if any
of these
conditions exist.Your dealer will know
I
the kind of wheel you need.
Each new wheel should have the same
load carrying capacity, diameter, width,
offset, and be mounted the same way
as
the one it replaces.
If you need to replace any
of your
wheels, wheel bolts, or wheel nuts,
replace them only with
new GM
original equipment parts. This way, you
will be sure to have the right wheels,
wheel bolts, and wheel nuts for your
Chevrolet model.
