We don’t make tires. Your new Corvette comes with
high-quality tires made by a leading tire manufacturer.
If you ever have questions about your tire warranty and
where to obtain service, see your Corvette Warranty
booklet for details.
Poorly maintained and improperly used tires are
dangerous.
Overloading your tires can cause
overheating as
a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle” in
the Index.

the correct inflation pressure for competitive or
high-speed driving.

Downloaded from www.Manualslib.com manuals search engine 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 km/h), 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.
Inflation -- Tire Pressure
The Tire-Loading Information label, which is on
the rear edge of the driver’s door, shows the correct
inflation pressures for your tires when they’re cold.
“Cold” means your vehicle has been sitting for at least
three hours or driven no more than
1 mile (1.6 km).
For competitive driving or high-speed driving (over
150 mph or 240 km/h), make sure your tires are inflated
to 35 psi
(240 kPa). When you end this type of driving,
reduce the cold inflation pressures (if necessary) to those
listed on the Tire-Loading Information label.
I NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not. If your tires
don’t have enough air (underinflation), you can get the following:
0 Too much flexing
Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
Bad fuel economy.
NOTICE: (Continued)

Downloaded from www.Manualslib.com manuals search engine You need a new tire if any of the following statements
are true:
You can see the indicators at three or more 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 cord or fabric.
0 The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
can’t be repaired well 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 Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on your
vehicle.
If your tires have an all-season tread
design, the TPC number will be followed by an
“MS”
(for mud and snow).
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 and construction type (bias,
bias-belted or radial) as your original tires.
A CAUTION:
Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes (other
than those originally installed on your Corvette)
or types (radial and bias-belted tires), the vehicle
may not handle properly, and you could have a
crash. Using tires of different sizes (other than
those originally installed on your Corvette) may
also cause damage to your vehicle. Be sure to use
the correct size and type tires on all four wheels.
It’s all right to drive with your compact spare
(if you have one). It was developed for use on
your vehicle.

Downloaded from www.Manualslib.com manuals search engine Uniform Tire Quality 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
grades are molded on the sidewalls
of most passenger
car tires. The Uniform Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary
use spare tires, tires with
nominal rim diameters of 10 to 12 inches (25 to
30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may
vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
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 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, and 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 (straightahead) 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.

Downloaded from www.Manualslib.com manuals search engine Cleaning and Storage of Your
Hardtop
The optional hardtop has the same durable finish as the
painted surfaces of your Corvette. You can wash, polish
and wax it.
If you store the hardtop for a long time, keep it covered
in a dry place. Apply silicone grease to all the
weatherstrips.
Aluminum Wheels
Your aluminum wheels have a protective coating similar
to the painted surface of your vehicle. Don’t use strong
soaps, chemicals, chrome polish, abrasive cleaners or
abrasive cleaning brushes on them because you could
damage this coating. After rinsing thoroughly, a wax
may be applied.
NOTICE:
,
Don’t use an automatic car wash that has hard
silicon carbide cleaning brushes. These brushes
can take the protective coating
off your
aluminum wheels.
Tires
To clean your tires, use a stiff brush with a tire cleaner.
NOTICE:
When applying a tire dressing always take care to
wipe
off any overspray or splash from all painted
surfaces on the body
or wheels of the vehicle.
Petroleum-based products may damage the paint
finish.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas
of finish damage can be corrected
in your dealer’s body and paint shop.

KEEP ENGINE OIL
AT THE PROPER
LEVEL AND CHANGE AS
RECOMMENDED
This section covers the maintenance required for your
Corvette. Your vehicle needs these services to retain its
safety, dependability and emission control performance.
I Protection
Plan
Have you purchased the GM Protection Plan? The Plan
supplements
your new vehicle warranties. See your
Warranty and Owner Assistance booklet, or your
Corvette dealer
for details.
Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality
of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase the level
of emissions from your vehicle.
To help protect our
environment, and to keep your vehicle in good
condition, please maintain your vehicle properly.

Downloaded from www.Manualslib.com manuals search engine How This Section is Organized
The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services” shows
what to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department or another qualified
service center do these jobs.
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you can
be seriously injured.
Do your own maintenance
work only
if you have the required know-how
and the proper tools and.equipment for the job.
If you have any doubt, have a qualified
technician do the work. “Part
B: Owner
Checks and Services’’ tells you what
should be checked whenever you stop for fuel. It also
explains what you can easily do to help keep your
vehicle in good condition.
“Part C: Periodic Maintenance Inspections”
explains important inspections that your Corvette
dealer’s service department or another qualified service
center should perform.
“Part D: Recommended Fluids and Lubricants”
lists some products GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether you do the work
yourself
or have it done.
“Part E: Maintenance Record’’ provides a place
for you to record the maintenance performed
on your
vehicle. Whenever any maintenance is performed, be
sure to write it down in this part.
This will help you
determine when your next maintenance should be done.
In addition, it is a good idea to keep your maintenance
receipts. They may be needed to qualify your vehicle for
warranty repairs.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information
GM publishes. See “Service and Owner
Publications” in the Index.

Downloaded from www.Manualslib.com manuals search engine Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it. You may drive
very short
distances only a few times a week. Or you may drive
long distances all the time in very hot, dusty weather.
You may use your vehicle in making deliveries. Or
you may drive it to work,
to do errands or in many
other ways.
Because of all the different ways people use their
GM
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements than you’ll find
in the schedules in this section.
So please read this
section and note how you drive. If you have any
questions
on how to keep your vehicle in good
condition, see your Corvette dealer.
This part tells you the maintenance services you should
have done and when you should schedule them. If you
go to your dealer for your service needs, you’ll know
that GM-trained and supported service people will
perform the work using genuine
GM parts. The
proper fluids and lubricants to use are listed in
Part D. Make sure whoever services your vehicle
uses these. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle.
These schedules are for vehicles that:
carry passengers and cargo within recommended
limits. You will find these limits on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle’’ in the Index.
are driven on reasonable road surfaces within legal
driving limits.
use the recommended fuel. See “Fuel” in the Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule to follow:
