Never  remove  or  restore a tire  frondto  a  stowage 
position  under  the  vehicle  while  the  vehicle 
is 
supported  by a jack. Always  tighten  the  tire 
fully  against  the  underside  of  the  vehicle  when  restowing 
A flat rear tire reduces  clearance to remove  the spare 
tire.  If there is less than 
12 inches (30.48 cm)  between 
the ground and the rear bumper  or any  trailer hitch,  jack 
up  the vehicle 
until the  flat  tire  is off  the ground. 
(See  “Removing 
the Flat Tire” and “Installing the 
Spare  Tire,’’  Steps 
4 through 8, in this  section.) 
Unless your vehicle has  a  flat rear tire,  do not  remove 
or 
restore  a  tire from/to a stowage  position  under the 
vehicle while  the vehicle is  supported  by a  jack.  Always 
tighten the tire 
fully against the underside of the vehicle 
when  restowing. 
If you  have  a vehicle  which  was  completed from a cab 
and chassis,  refer to the information from the  body 
suppliedinstaller. 
The  spare  tire 
is a full size tire, like the  other tires on 
your vehicle. 
For cargo  vans, the jack 
is secured 
in the  rear 
Remove  the retaining  wing bolt and lift 
it off  the 
mounting bracket.  Set the jack  and jacking  equipment 
near the 
flat tire.

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. 
Whenever  a  wheel,  wheel bolt or wheel nut is replaced 
on  a  dual  wheel setup,  check  the wheel 
nut torque after 
100, 1,000 and 6,000 miles (160,  1  600 and 10 000 km) 
of driving.  For  proper  torque,  see  “Wheel  Nut Torque” 
in  the  Index. 
See  “Changing  a  Flat Tire” 
in the Index  for 
more  information. 
Used Replacement Wheels 
Putting  a  used  wheel  on  your vehicle 
is 
dangerous.  You can’t  know  how  it’s  been  used  or 
how  many  miles  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.
