spare tire CHEVROLET CORVETTE 1998 5.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine If a Tire Goes Flat
Your Corvette has neither a spare tire nor tire changing
equipment, because it was built with Goodyear
Extended Mobility Tires (EMT). See “Extended
Mobility Tires” in the Index.
A C.* UTION:
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.
Because your vehicle has no spare tire, no tire
changing equipment, and no provisions to store a
tire
in the vehicle, special tools and procedures
are required if a tire needs to be serviced.
If these
tools and procedures aren’t 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 GM Corvette
Service Manual, are used.
To order a service manual, see “Service and Owner
Publications” in the Index.
A CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured.
And, the transmission or other parts of the
vehicle can 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 (55 km/h) as shown
on the speedometer.

Your vehicle, when new, had Goodyear Extended
Mobility Tires (EMT). 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 Tire Pressure Monitor (TPM) is
used to alert you if a tire has lost pressure.
The Tire Pressure Monitor (TPM) has a sensor on
each road wheel that transmits to a receiver on the
instrument panel.
The system operates on a radio frequency subject to
Federal Communications Commission (FCC) Rules and
with Industry and Science Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and
(2)
this device must accept any interference received,
including interference that may cause undesired operation.
This device complies with RSS-210 of Industry and
Science Canada. Operation is subject to the following
two conditions: (1) this device may not cause
interference, and (2) this device must accept any
interference received, including interference that may
cause undesired operation of the device. Changes or modifications
to this system
by other than an
authorized service facility could void authorization to
use this equipment.
If a tire’s inflation pressure is between
5 psi (35 kPa)
and 25 psi (170 kPa), you will see a message on the
Driver Information Center. This message will show
which tire is underinflated and two chimes will sound.
An example would
be LOW TIRE PRESSURE-LR.
This would mean that the inflation pressure in your left
rear tire is between 5 psi (35 Pa) and 25 psi (170 Pa).
If the inflation pressure in the tire drops below
5 psi
(35 Ea), the message would read FLAT TIRE-LR and
four chimes will sound.
See “Driver Information
Center” in the Index.
The TPM will also alert you if a tire’s pressure is higher
than
42 psi (290 Wa). The message will show which tire
is overinflated and two chimes will sound. An example
would be HIGH PRESSURE-LR. This would mean that
the inflation pressure in your left rear tire is higher than
42 psi (290 kPa). See “Driver Information Center” in
the Index.
If a tire pressure message appears on the Driver
Information Center, stop as soon as you can. Have
the
tire pressures checked and set to those shown on your
Tire Loading Information label. See “Inflation
-- Tire
Pressure” in the Index.

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 (straight ahead) traction tests and does not
include cornering (turning) traction.
