Compact Spare Tire
Although the compact spare was fully
inflated when your vehicle was new, it
can lase air after a time. Check the
inflation pressure regularly. It should be
60 psi (420 1tPa). The compact spare is
made to go up to 3,000 miles (5 OOO 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 .s.parewith .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.
!36
'OTIC E
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.

If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your
vehicle is stuck is to spin your wheels.
The method
known as “rocking” can
rou must use caution. I help you get out when you’re stuck, but
CAUT/UN I
A: If :you let.your :tires. spin -at
high speed.when the ASR
, . ‘OFE warning light is on, or when
“the SERVICE ASR warning light is
‘on, your tires can explode and you
or others could be injured. And,
spinning your tires with either of
these lights on can cause the
automatic transmission
or other
parts of the vehicle to overheat.
That could cause an engine
compartment fire or other damage.
When you’re stuck, spin the wheels
as little as possible. Don’t spin the
wheels above 35 mph (56 M) as
shown on the speedometer.
Rocking Your Vehicle to Get It Out:
First, turn your steering wheel left and
right. That will clear the area around
your front wheels. You should turn your
ASR system off. Then, shift back and
forth between R (Reverse) and a
forward gear--or if you have a manual
transmission, between 1 or 2 and
R (Reverse)-spinning the wheels as
little as possible. Release the accelerator
pedal while
you shift, and press lightly
on the accelerator pedal when the
transmission is in gear.
If that doesn’t
get
you out after a few tries, you may
need to be towed out.
If you do need to
be towed
out, see the Index under
Towing Your Corvette and Acceleration
Slip Regulation (ASR) System.

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 1tPa).
How to Check:
Use the tire pressure gage provided in
your center storage console 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 Rotation
The tires on your Corvette are
directional, asymmetrical, and are
different sizes
front tu rear. Due to this,
your tires should not be rotated. Each
tire
and wheel should be used only in
theqosition it
is in.

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 ha
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 ruste-d.
If wheel nuts keep
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
the lund
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 wheel, wheel
bolts, and wheel
nuts for your Corvette.
