If a tire goes at, 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
deated EMT for 25 miles (40 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 100 miles (160 km) at speeds up to
55 mph (90 km/h), but the tire would then have to
be replaced. When a tire is lled with air, it provides
a cushion between the road and the wheel.
Because you won’t have this cushion when driving
on a deated 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 even before
you’ve driven on the tire in a deated condition.
When a tire has been damaged, or if you’ve driven
any distance on a deated EMT, check with an
authorized 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.As soon as possible, contact the nearest
authorized GM or Goodyear EMT servicing facility
for inspection and repair or replacement. To locate
the nearest GM or Goodyear EMT servicing facility,
call Roadside Assistance. For phone numbers
and Roadside Assistance details seeRoadside
Assistance Program on page 458. You may also
contact Goodyear, for the nearest authorized EMT
servicing facility, by calling 1-800-789-9878.
{CAUTION:
Extended mobility tires are constructed
differently than other tires and could
explode during improper service. You or
others could be injured or killed if you
attempt to repair, replace, dismount, or
mount a extended mobility tire. Let only
an authorized EMT Service Center repair,
replace, dismount and mount extended
mobility tires.

When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including
the installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle’s
original equipment tires and the correct ination
pressure for your vehicle’s tires when they
are cold. SeeLoading Your Vehicle on page 309,
for an example of the tire information label and
its location on your vehicle. Also seeInation - Tire
Pressure on page 386.Your vehicle’s TPMS can alert you about a
low or high tire pressure condition but it does
not replace normal tire maintenance. See
Ination - Tire Pressure on page 386and
When It Is Time for New Tires on page 393.
The SERVICE TIRE MONITOR message,
in the DIC, is displayed when the TPMS is
malfunctioning. For example, one or more
TPMS sensors may be inoperable or missing.
Also, the active handling system will be affected,
seeActive Handling System on page 283.
See your dealer for service.

TPMS Sensor Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of the
TPMS sensors, the identication codes will need
to be matched to the new tire/wheel position.
The sensors are matched, to the tire/wheel
positions, in the following order: driver’s side front
tire, passenger’s side front tire, passenger’s side
rear tire, and driver’s side rear tire using a TPMS
diagnostic tool. See your GM dealer for service.

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 specied government
test course. For example, a tire graded 150 would
wear one and a half (1.5) 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 signicantly from the norm due to variations
in driving habits, service practices, and differences
in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA,
A, B, and C. Those grades represent the tire’s
ability to stop on wet pavement as measured under
controlled conditions on specied 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 straight-ahead braking traction
tests, and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
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 specied 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 inated and
not overloaded. Excessive speed, underination,
or excessive loading, either separately or in
combination, can cause heat buildup and
possible tire failure.

If you ever use a jack to lift your vehicle, follow
the instructions that came with the jack, and
be sure to use the correct lifting points to avoid
damaging your vehicle.
Notice:Lifting your vehicle improperly
can damage your vehicle and result in
costly repairs not covered by your warranty.
To lift your vehicle properly, follow the
advice in this part.
To help prevent vehicle damage:
Be sure to place a block or pad between
the jack and the vehicle.
Make sure the jack you’re using spans
at least two crossmember ribs.
Lift only in the areas shown in the
following pictures.
For additional information, see your dealer
and the Chevrolet Corvette service manual.
Lifting From the Front
The front lifting points can be accessed from
either side of your vehicle, behind the front tires.

3. Lift the vehicle with the jack, making
sure the jack spans at least two of the
crossmember ribs (B).
For more information, seeDoing Your
Own Service Work on page 320.
If a Tire Goes Flat
Your Corvette has no spare tire, no tire changing
equipment, and no place to store a tire.
It is unusual for a tire to blow out while you are
driving, especially if you maintain your tires
properly. SeeTires on page 378. If air goes out
of a tire, it is much more likely to leak out slowly.
Your vehicle has Extended Mobility Tires (EMT),
so you will not need to stop on the side of the
road to change a at tire. EMT tires can operate
effectively with no air pressure. If you drive
on a deated EMT for 25 miles (40 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.
Contact the nearest authorized Chevrolet or
Goodyear EMT servicing facility, as soon as
possible, to have the at tire inspected and
repaired or replaced. For more information,
seeExtended Mobility Tires on page 384.
406

{CAUTION:
Special tools and procedures are required
to service an Extended Mobility Tire (EMT).
If these special tools and procedures are
not used you or others could be injured
and your vehicle could be damaged.
Always be sure the proper tools and
procedures, as described in the service
manual, are used.
To order a service manual, seeService
Publications Ordering Information on page 468.
Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its
best if it is cleaned often. Although not always
visible, dust and dirt can accumulate on your
upholstery. Dirt can damage carpet, fabric,
leather, and plastic surfaces. Regular vacuuming
is recommended to remove particles from your
upholstery. It is important to keep your upholstery
from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible.
Your vehicle’s interior may experience extremes
of heat that could cause stains to set rapidly.
Lighter colored interiors may require more
frequent cleaning. Use care because newspapers
and garments that transfer color to your home
furnishings may also transfer color to your
vehicle’s interior.

the surface. Do not use chrome polish on
aluminum wheels.
Notice:Using chrome polish on aluminum
wheels could damage the wheels. The repairs
would not be covered by your warranty.
Use chrome polish on chrome wheels only.
Use chrome polish only on chrome-plated wheels,
but avoid any painted surface of the wheel, and
buff off immediately after application.
Notice:If you drive your vehicle through an
automatic car wash that has silicone carbide
tire cleaning brushes, you could damage
the aluminum or chrome-plated wheels.
The repairs would not be covered by your
warranty. Never drive a vehicle equipped with
aluminum or chrome-plated wheels through
an automatic car wash that uses silicone
carbide tire cleaning brushes.Tires
To clean the tires, use a stiff brush with
tire cleaner.
Notice:Using petroleum-based tire dressing
products on your vehicle may damage the
paint nish and/or tires. When applying a
tire dressing, always wipe off any overspray
from all painted surfaces on your vehicle.
Finish Damage
Any stone chips, fractures or deep scratches in
the nish 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 nish
damage can be corrected in your dealer’s
body and paint shop.
