Although the compact spare was fully inflated when your
vehicle was new,
it can lose air after a time. Check the
inflation pressure regularly. It should be
60 psi (420 Wa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your spare
tire is correctly inflated. The compact spare is made to
perform well at posted speed limits for distances up to
3,000 miles (5 000 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.
Tighten the straps by pulling on the loose ends.
When the tire is stored in the rear cargo area, you can’t
store
a removable roof panel. It will not fit into the
latches properly.
Raise the tire carrier tray to its upper position and
tighten the latch bolt until
it is snug.
Put the wheel wrench back in its place under the driver’s seat.
Be sure to tighten the wingnuts.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Don’t take your compact spare through an
automatic car wash with guide rails. The
compact spare can get caught on the rails. That
can damage the tire and wheel, and maybe other
parts
of your vehicle.
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.
NOTICE:
Tire chains won’t fit your compact spare. Using
them
will damage your vehicle and destroy the
chains too. Don’t use tire chains on your compact
spare.
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
too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires. If you spin the wheels
too fast while shifting your transmission back
and forth, you can destroy your transmission.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
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. (See
“ASR System” in the Index.)
Then shift back and forth between REVERSE (R) and a
forward gear (or with a manual transmission, between
FIRST
(1) or SECOND (2) gear and REVERSE (R)),
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
“Towing Your Vehicle” in the Index.

When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme ll@ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid
reservoir cap before removing it.
NOTICE:
0 Don’t let someone put in the wrong kind of
fluid. For example, just
a few drops of
mineral-based oil, such as engine oil, in
your brake system can damage brake
system parts
so badly that they’ll have to be
replaced.
Brake fluid can damage paint, so be careful
not to spill brake fluid on your vehicle.
If
you do, wash it off immediately. See
“Appearance Care” in the Index.
Brake Wear
Your Corvette has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a
high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and
go or be heard all the time your vehicle is moving (except
when you are pushing
on the brake pedal firmly).

Downloaded from www.Manualslib.com manuals search engine Extended Mobility Tires (Option)
If your Corvette has optional Goodyear Extended
Mobility Tires (EMT’s), the tires will have “EMT”
molded on the sidewalls. Your vehicle may also have a
spare tire delete option. With the spare tire delete option,
there’s no spare tire, no tire changing equipment and no
place to store a tire in the vehicle. Extended Mobility
Tires perform
so well without any air that a Low Tire
Pressure Warning System (LTPWS) is used to alert you if
a tire has lost pressure.
A LOWELAT TIRE light will
appear on your Driver Information Center
if a tire’s
inflation pressure is less than
25 psi (170 kPa). If the
LOW/FLAT
TIRE light comes on, check your tire
pressures as soon as you can. See “Low Tire Pressure
Warning System” in the Index for additional information. If a
tire goes flat,
you won’t need to stop on the side of
the road to change the tire. You can just keep on driving.
The shorter the distance
you drive and the slower the
speed, the greater the chance that the tire will not have
to be replaced. If
you drive on a deflated EMT for
distances
of 50 miles (80 km) or less and at speeds of
55 mph (90 km/h) or less, there is a good chance that the
tire can be repaired. The tire can operate effectively with
no air pressure for up to 200 miles (320 km) at speeds
up to
55 mph (90 kmk), but the tire would then have to
be replaced. Also remember: When a tire is filled with
air, it provides a cushion between the road and the
wheel. Because you do not have this cushion when
driving on a deflated tire, try to avoid potholes that
could damage your wheel and require replacement of it.
Some road hazards can damage a tire beyond repair. This
damage could occur before you’ve driven on the tire
in a
deflated condition. Whenever a tire has been damaged, or
if you’ve driven any distance on a deflated EMT, check
with a Goodyear EMT Service Center to determine
whether
the tire can be repaired or should be replaced.
To maintain your vehicle’s extended mobility feature,
all replacement tires must be Extended Mobility Tires.
See the Goodyear Extended Mobility Tire Owner’s
Manual and Limited Warranty supplied with your
Corvette for additional information.

Downloaded from www.Manualslib.com manuals search engine Tire Rotation
The tires on your Corvette are directional, asymmetrical,
and are different sizes front to rear. Due to this, your
tires should not be rotated. Each tire and wheel should
be used only in the position it is in.
When it’s Time for New Tires
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

Downloaded from www.Manualslib.com manuals search engine example, a tire graded 150 would wear one and a half
(1 1/2) 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 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.
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 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.

Downloaded from www.Manualslib.com manuals search engine 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
or corroded. 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
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 model.
I NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling,
speedometer/odometer calibration, headlamp aim, bumper height, vehicle ground clearance,
and tire clearance to the body and chassis.
