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.  If wheel  nuts keep 
coming  loose, the wheel, wheel  bolts, 
and  wheel  nuts should  be  replaced. 
If 
the wheel  leala  air,  replace  it  (except 
some  aluminum  wheels, which  can 
sometimes  be  repaired).  See your  Oldsmobile 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 
Oldsmobile  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.
