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.
