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 kPa).  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.

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. 
The  method  known  as  “rocking”  can help 
you  get out  when  you’re  stuck, but .you 
must  use caution.

Windshield  Wiper 
Blades 
It's  a  good  idea  to rotate the wiper  blade 
assembly 
180" every  six  months.  This 
changes the  wear  pattern  and  makes  the 
wiper  blade insert  last  longer. 
To rotate 01 
replace the  wipers: 
1. 
2. 
3. 
Pull the  wiper  arm away  from  the 
windshield. 
You should  be  able to see  part  of a 
spring  near  where  the  blade  connects 
to  the  arm.  Press  down  on the  spring 
with  a  screwdriver  and  pull  the wiper 
blade 
off. 
Rotate the  blade  and  push  it back  ontc 
the  arm.

he  driver's  door  tells  you the  proper  size, 
'peed  rating  and  recommended  inflation 
n-essures  for the  tires  on  your  vehicle. 
t  also  gives  you  important  information

Inflation - Tire  Pressure 
The Tire-Loading  Information  label  which  is  on  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  a  mile. 
For  competitive driving  or  high-speed driving (over 
150 mph  or 240 krn/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. 
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: 
0 Too  much  flexing 
0 Too  much  heat 
0 Tire overloading 
0 Bad  wear 
0 Bad  handling 
Bad fuel economy. 
If  your  tires have too  much air (overinflation),  you  can  get: 
Unusual  wear 
Bad handling 
0 Rough  ride 
Needless  damage from  road  hazards. 
When to Check: Check  your  tires 
mce 
a month  or  more.  Don’t  forget 
your  compact  spare  tire.  It  should  be  at 
50 psi (420 Wa). 
How to Check: Use  a  good  quality 
pocket-type  gauge  to check  tire 
pressure.  Simply  looking  at  the  tires 
will  not  tell  you  the  pressure, 
=specially  if  you  have  radial  tires 
- 
which  may  look  properly  inflated  even 
if they’re  underinflated. 
Lf your  tires  have  valve  caps,  be  sure  to 
put  them  back  on.  They  help  prevent 
leaks  by  keeping  out  dirt  and  moisture. 
Tire  Rotation 
I’he tires  on  your  Corvette  are 
lirectional,  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 
2/32 inch (1.6 mm)  or  less  of tread 
remaining. 
You  need  a new  tire if 
0 You  can  see  the  indicators  at three or 
You can see cord  or  fabric  showing 
0 The  tread or sidewall  is  cracked, cut 
more  places  around  the 
tire. 
through  the  tire’s  rubber. 
or  snagged  deep  enough  to show  cord 
or  fabric. 
0 The  tire has  a bump,  bulge  or split. 
0 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,  yobr  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 a 
“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. 
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.) 
Treadwear 
The treadwear  grade is a comparative 
rating  based on the  wear  rate of the tire 
when  tested  under controlled conditions
