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 
Too much  heat 
0 Tire  overloading 
Bad  wear 
Bad  handling 
0 Bad  fuel  economy. 
If your  tires  have  too  much  air  (overinflation), you can  get: 
Unusual wear 
Bad  handling 
Rough  ride 
Needless  damage from road  hazards. 
When to Check 
Check your tires once  a month or more. Also, check the  tire pressure  of the 
spare  tire. 
How to Check 
Use a good quality  pocket-type gage to check tire pressure. Simply looking 
at the tires  will not tell  you the pressure, especially 
if you have  radial  tires 
- which  may look properly inflated even  if they’re  underinflated. 
If  your tires have  valve  caps, be sure to put them back  on. They help prevent 
leaks  by keeping  out  dirt and moisture. 
Tire  Inspection  and  Rotation 
Tires should be  inspected  every 6,000 to 8,000 miles (10 000 to 13 000 km) 
for any signs of unusual  wear. If unusual wear  is present, 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. 
If your vehicle has dual rear 
wheels,  also  see 
“Dual Tire Operation”  later in this section.

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. 
In most cases, you will not need to have your wheels aligned  again. 
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 
GM dealer  if any of 
these  conditions  exist. 
Your dealer  will know the kind  of wheel  you need. 
Each  new wheel  should have the same load  carrying capacity, diameter, 
width, offset,  and be mounted the  same way as the  one 
it replaces. 
If you need to replace  any of your  wheels, wheel bolts,  or wheel  nuts, 
replace them  only with new 
GM original  equipment  parts. This way,  you 
will be sure to have  the right  wheel, wheel bolts,  and wheel nuts for your 
vehicle. 
A CAUTION: 
Using  the wrong replacement  wheels,  wheel  bolts,  or wheel  nuts 
on  your  vehicle  can be dangerous.  It could  affect  the  braking 
and  handling 
of your  vehicle,  make your tires  lose air  and  make 
you  lose  control, You could have a  collision in which 
you or 
others  could be injured.  Always  use  the correct  wheel,  wheel 
bolts,  and wheel 
nuts for replacement. 
NOTICE: 
The  wrong  wheel  can also cause problems  with bearing  life, 
brake  cooling,  speedometer/odometer calibration, headlamp 
aim,  bumper  height,  vehicle  ground clearance,  and  tire or  tire 
chain clearance to  the body  and chassis.
