Wheel  Replacement 
Replace any  wheel  that  is bent,  cracked  or badly rusted. 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 
GM  model. 
NOTICE: 
The  wrong  wheel  can  also  cause  problems  with  bearing  life, 
brake  cooling,  speedometer/odometer  calibration,  headlight  aim,  bumper  height,  vehicle  ground  clearance,  and  tire  or  tire  chain\
 
clearance  to  the  body  and  chassis.
