Storing a jack, a tire, or other equipment in the passenger
b compartment of the vehicle could cause injury. In a sudden stop or
collision, loose equipment could strike someone. Store all these\
in
I the proper place.
Compact Spare Tire
Although the compact spare was fully inflated when your vehicle\
was new, it
can lose air after a time. Check the inflation pressure regula\
rly. It should be
60 psi (420 kPa). The compact spare is made to go up to 3,000 miles
(5000 km), so you can finish your trip and have your full-size tire repaired\
or
replaced where you want. Of course, it’s best
to replace your spare with a
full-size tire as soon as you can. Your spare
will last longer and be in good
shape in case you need
it again.
Don’t use your compact spare on some other vehicle.
And don’t mix your compact spare or wheel with other wheels\
or tires. They
won’t fit. Keep your spare and its wheel together.
Tire chains won’t fit your compact spare. Using them will d\
amage your vehicle and destro) “re chc”? too. Don’t use
ti- chair - 3n your compacl
spare.

Loading Your Vehicle
K3651
The Certificationrrire label is found on the rear edge of the driver’s door. The
label shows the size of your original tires and the inflation pressures needed
to obtain the gross vehicle weight capacity of your vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of the
vehicle, all occupants, fuel and cargo.
The Certificationflire label also tells you the maximum weights for the front
and rear axles, called Gross Axle Weight Rating (GAWR).
To find out the
actual loads on your front and rear axles, you need
to go to a weigh station
and weigh your vehicle. Your dealer can help you with this. Be sure
to
spread out your load equally on both sides of the centerline.
Never exceed the GVWR for your vehicle, or the Gross Axle Wei\
ght Rating
(GAWR) for either the front or rear axle.
And,
if you do have a heavy load, you should spread it out.
Do not load your vehicle any heavier than the GVWR or the
- maximum front and rear GAWRs. If you do, parts on your vehicle
can break, or
it can change the way your vehicle handles. These
could cause you
to lose control. Also, overloading can shorten the
life
of your vehicle. I

When lt3 Time for New Tires
K1656
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
2/32 inch (1.6 mm) or
less of tread remaining.
You need a new tire
if:
You can see the indicators at three places around the tire.
You can see cord or fabric showing through the tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep enough to show
The tire has a bump, bulge or split.
cord
or fabric.
The tire has a puncture, cut, or other damage that can’t be repaired
because of the size or location of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at the CertificationRire
label. The tires installed on your vehicle when
it was new had a Tire
Performance Criteria Specification (TPC Spec) number on each t\
ire’s sidewall.
When you get new tires, get ones with that same TPC Spec num\
ber. That
way, your vehicle will continue to have tires that are designed to give proper
endurance, handling, speed rating, traction, ride and other thin\
gs during normal service on your vehicle. If your tires have an all-season tread design,
the
TPC number will be followed by a “MS” (for mud and snow).
6-48

Downloaded from www.Manualslib.com manuals search engine If you ever replace your tires with those not having a TPC Spec \
number,
make sure they are the same size, load range, speed rating an\
d construction
type (bias, bias-belted
or radial) as your original tires.
A
Mixing tires could cause you to lose control while driving. If you mix
tires
of different sizes or types (like radial and bias-belted tires) the
vehicle may not handle properly, and you could have a crash. Be
sure
to use the same size and type tires on all wheels. I
It’s all right to drive with your compact spare, though. It was developed for
limited use on your vehicle.
Uniform Tire Quality Grading
The following information relates to the system developed by the United
States National Highway Traffic Safety Administration which grade\
s tires by
treadwear, traction and temperature performance. (This applies o\
nly
to
vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on the wear \
rate of the
tire when tested under controlled conditions on a specified governmen\
t test
course.
For example, a tire graded 150 would wear one and a half (142)
times as well on the government course as a tire graded 100. The relative
performance of tires depends upon the actual conditions
of their use,
however, and may depart significantly from the norm due to var\
iations in
driving habits, service practices and differences in road charac\
teristics 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.
Temperatur+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 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

I
Using the wrong replacement wheels, wheel bolts, or wheel nuts \
on
your vehicle can be dangerous. It could affect the braking and\

handling
of your vehicle, make your tires lose air and make you lose
control. You could have a collision in which you or others could be
injured. Always use the correct wheel, wheel bolts, and wheel \
nuts
for replacement.
NOTICE I
The wrong wheel can also cause problems with bearing life, bra\
ke cooling, speedometer/odometer calibration, headlight aim, bumper height, vehiclc
ground clearance, and tire
or tire chain clearance to the body and chassi I
Used Replacement Wheels
Putting a used wheel on your vehicle is dangerous. You can’t know
how it’s been used or how many miles it’s been driven. It could fail
suddenly and cause an accident.
If you have to replace a wheel use
1 a new GM original equipment wheel.
Tire Chains
f your vehicle has PqA
iamage your vehicle
f you have other size tires, use tire chains only when you ... st. se on
SAE Class “S” type chains that are the proper size for your tires. lnst
hem on the rear axle tires and tighten them
as tightly as PO
he ends securely fastened. Drive slowly and follow the chain
nanufacturer’s instructions.
If you can hear the chains contacting your
rehicle, stop and retighten them.
If the contact continues, slow d8
t stops. Driving too fast with chains on will damage your vehicle.
