11. Tighten the wheel nuts  firmly  in a 
crisscross sequence. 
Incorrect  wheel nuts  or  improperly  tightened 
wheel  nuts  can  cause the wheel  to become  loose 
and  even  come 
off. This could lead  to  an accident. 
Be  sure  to use  the  correct  wheel nuts. If  you  have 
to  replace them,  be sure  to  get  new 
GM original 
equipment  wheel nuts. 
Stop  somewhere 
as soon as you can and  have  the 
nuts  tightened  with 
a torque wrench to 100 lb-ft 
(140 Nom). 
NOTICE: 
Improperly  tightened wheel nuts  can  lead to 
brake  pulsation  and  rotor  damage. 
To avoid 
expensive  brake repairs,  evenly tighten  the wheel 
nuts  in the  proper  sequence  and to  the  proper 
torque  specification. 
Don’t try to put the wheel  cover on the compact 
spare  tire. It won’t  fit.  Store the wheel cover  in the 
trunk until 
you have replaced the compact  spare  tire 
with  a regular tire. 
NOTICE: 
Wheel  covers  won’t fit on your  compact  spare. If 
you try to put a wheel  cover on  your compact 
spare,  you could  damage  the  cover or the  spare. 
When  you re-install  the  full  size wheel and tire,  you 
install 
the wheel  cover or nut caps at this point.

Storing the Spar1 rire and Tools 
I A CAUTION: 
Storing a jack,  a tire or other  equipment in the 
passenger  compartment 
of the  vehicle  could 
cause  injury.  In  a sudden  stop  or  collision,  loose 
equipment  could  strike  someone. 
Store all these 
in  the  proper  place. 
The  compact  spare is for temporary  use  only.  Replace 
the  compact  spare  tire  with  a  full-size  tire  as  soon 
as you 
can.  See  “Compact  Spare  Tire”  later in 
this section.  See 
the  storing  instructions  label 
to replace your compact 
spare  into 
your  trunk properly.

Compact Spare Tire 
Although  the  compact  spare  tire  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 Wa). 
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  speeds  up  to 65 mph 
(105 km/h) 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: 
When  the  compact spare is installed,  don’t  take 
your  vehicle  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 other  vehicles. 
And  don’t  mix  your  compact  spare  tire 
or wheel  with 
other  wheels  or  tires.  They  won’t  fit. Keep  your  spare 
tire  and  its wheel  together. 
NOTICE: 
Tire  chains  won’t fit  your  compact  spare. Using 
them  can  damage  your  vehicle  and  can damage 
the  chains  too.  Don’t  use  tire chains  on  your 
compact  spare.

Mixing tires  could  cause  you to  lose  control  while 
driving. 
If you  mix  tires of different sizes or types 
(radial and  bias-belted  tires),  the  vehicle  may  not 
handle  properly,  and  you  could  have 
a crash. 
Using  tires 
of different  sizes  may  also  cause 
damage  to  your  vehicle.  Be  sure to  use  the  same 
size  and  type  tires on  all  wheels. 
It’s  all  right  to drive  with  your  compact  spare, 
though. 
It was developed for use on your vehicle. 
I a CAUTION: 
If you  use  bias-ply  tires on your  vehicle,  the 
wheel  rim  flanges  could  develop  cracks  after 
many  miles 
of driving. A tire  and/or  wheel  could 
fail  suddenly,  causing  a  crash.  Use  only  radial-ply 
tires  with  the  wheels  on  your  vehicle. 
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 
(PC) standards.

NOTICE: 
The  wrong  wheel  can also cause  problems  with 
bearing  life,  brake cooling,  speedometer  or 
odometer  calibration, headlamp  aim, bumper 
height,  vehicle  ground clearance and  tire or tire 
chain  clearance  to the  body  and chassis. 
See “Changing a Flat  Tire”  in the Index  for more 
information. 
Used  Replacement  Wheels 
I 
A CAUTION: 
Putting a used  wheel  on  your vehicle is 
dangerous.  You can’t  know  how  it’s been  used  or 
how  far it’s  been  driven. It could  fail  suddenly 
and  cause  an accident. 
If you have to  replace a 
wheel,  use a new GM original equipment  wheel. 
Tire  Chains 
I 
NOTICE: 
Use tire chains  only  where  legal  and only  when 
you  must.  Use  only 
SAE Class “S” type chains 
that  are  the  proper size for your  tires.  Install 
them  on  the front  tires and tighten them as 
tightly 
as possible  with  the ends securely 
fastened.  Drive  slowly  and follow  the chain 
manufacturer’s  instructions. 
If you  can hear  the 
chains  contacting  your  vehicle,  stop  and retighten 
them. 
If the contact  continues, slow down until it 
stops.  Driving  too  fast or spinning the  wheels 
with  chains  on  will  damage your  vehicle.
