Tires 
Your  new  vehicle comes with  high-quality  tires made  by 
a leading  tire  manufacturer. If you ever have questions 
about  your  tire  warranty  and  where 
to obtain  service,  see 
your 
GM Warranty  booklet  for  details.

Downloaded from www.Manualslib.com manuals search engine A CAUTION: 
Poorly  maintained  and  improperly used tires 
are  dangerous. 
Overloading  your  tires  can  cause 
overheating  as  a  result  of too  much  friction. 
You  could  have  an  air-out  and  a  serious 
accident.  See “Loading  Your Vehicle”  in 
the  Index. 
0 Underinflated  tires  pose the  same  danger as 
overloaded  tires.  The  resulting  accident 
could  cause  serious  injury.  Check  all  tires 
frequently  to  maintain  the  recommended  pressure.  Tire  pressure  should  be  checked 
when  your  tires  are  cold. 
Overinflated  tires  are  more  likely to be  cut, 
punctured  or  broken  by a  sudden 
impact 
-- such  as  when you hit a pothole. 
Keep  tires 
at the  recommended  pressure. 
Worn,  old  tires  can  cause  accidents. If your 
tread 
is badly  worn,  or if your  tires  have 
been  damaged,  replace  them. 
Inflation -- Tire  Pressure 
The  CertificatiodTire  label, which  is  on the  rear  edge of 
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 
1 mile (1.6 km). 
NOTICE: 
I 
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  the  following: 
0 Too much  flexing 
0 Too much  heat 
0 Tire  overloading 
0 Bad  wear 
Bad  handling 
Bad  fuel  economy.

Downloaded from www.Manualslib.com manuals search engine NOTICE: (Continued) 
If  your  tires  have  too 
much air  (overinflation), 
you can  get  the  following: 
0 Unusual  wear 
Bad  handling 
Rough  ride 
Needless  damage  from  road  hazards. 
When  to Check 
Check  your  tires once a month or more. 
Don’t  forget  your  compact spare tire.  It  should  be  at 
60 psi (420 kPa). 
How to Check 
Use a  good  quality  pocket-type  gage to check tire 
pressure.  You can’t  tell 
if your  tires are properly  inflated 
simply  by  looking  at  them.  Radial  tires  may  look 
properly  inflated  even when  they’re  underinflated. 
Be sure  to put  the  valve  caps back  on  the  valve  stems. 
They  help prevent  leaks  by  keeping 
out dirt 
and  moisture. 
Tire  Inspection  and  Rotation 
Tires should  be rotated  every 6,000 to 8,000 miles 
( 10 000 to 13 000 km).  Any  time you notice  unusual 
wear,  rotate  your  tires  as soon  as possible  and  check 
wheel  alignment.  Also  check  for damaged  tires  or 
wheels. 
See “When It’s Time  for New  Tires”  and 
“Wheel  Replacement’’  later  in  this  section  for 
more  information. 
The  purpose 
of regular  rotation is to achieve  more 
uniform  wear  for all  tires  on  the  vehicle.  The first 
rotation  is 
the most  important.  See “Scheduled 
Maintenance  Services”  in 
the Index  for scheduled 
rotation  intervals. 
3 
When  rotating  your  tires,  always use  the  correct  rotation 
pattern  shown  here.

Don’t include  the compact  spare  tire in your 
tire rotation. 
After the tires  have been rotated,  adjust  the front and 
rear inflation  pressures as shown on the 
Certificationire  label. Make certain that  all wheel  nuts 
are properly tightened.  See  “Wheel Nut Torque”  in 
the  Index. 
Rust  or  dirt  on  a  wheel, or  on  the  parts  to  which 
it 
is fastened,  can  make  wheel nuts  become  loose 
after 
a time.  The  wheel  could  come off and  cause 
an  accident.  When  you change 
a wheel,  remove 
any  rust  or  dirt  from  places  where  the wheel 
attaches  to  the  vehicle. 
In an emergency,  you can 
use 
a cloth  or  a  paper  towel to do this; but  be 
sure  to  use 
a scraper  or  wire brush  later, if you 
need  to,  to  get all  the  rust  or  dirt 
off. (See 
“Changing 
a Flat  Tire”  in  the  Index.)  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 
1/16 inch (1.6 mm) or 
less  of tread remaining. 
You  need  a new  tire if  any  of  the following  statements 
are  true: 
0 You can  see  the  indicators at three or more places 
around  the tire. 
0 YOU  can  see  cord or fabric showing through the 
tire’s  rubber. 
The tread  or sidewall is  cracked,  cut  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.

Downloaded from www.Manualslib.com manuals search engine Buying New Tires 
To find  out  what  kind  and size of  tires  you  need,  look  at 
the CertificationRire  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 
your  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  an 
“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. 
I A CAUTION: 
--- 
Mixing  tires  could  cause  you to lose  contrc  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. 
If you use  bias-ply  tires  on  your  vehil , 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.

Downloaded from www.Manualslib.com manuals search engine Uniform  Tire  Quality  Grading Treadwe: 
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. 
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.

Downloaded from www.Manualslib.com manuals search engine 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 specified 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 inflated  and  not 
overloaded. Excessive  speed, underinflation,  or 
excessive  loading, either separately  or in combination, 
can  cause  heat buildup  and possible  tire failure. 
Wheel  Alignment  and  Tire  Balance 
The  wheels  on  your  vehicle were aligned and balanced 
carefully 
at the factory  to give  you the longest  tire  life 
and  best  overall performance. 
Scheduled  wheel alignment  and  wheel  balancing are  not 
needed.  However, 
if you  notice  unusual  tire  wear  or 
your  vehicle pulling  one 
way or the other,  the alignment 
may  need  to be  reset. 
If you  notice your vehicle 
vibrating  when driving  on a smooth road,  your  wheels 
may  need 
to be  rebalanced. 
Wheel  Replacement 
Replace  any  wheel that is bent,  cracked,  or  badly rusted 
or  corroded. 
If wheel  nuts  keep  coming loose, the wheel, 
wheel  bolts and  wheel  nuts  should be replaced. 
If the 
wheel  leaks air, replace 
it (except  some aluminum 
wheels,  which  can sometimes  be repaired). See 
your 
dealer  if any  of these  conditions  exist.
