Wheel Replacement - GMC TopKick 2007 Owner's Manual

How Often to Check
Wheel tightness is so important you should have a
technician check nut tightness on all wheels
with a torque wrench after your first 100 miles
(160 km), and then 1,000 miles (1 600 km) after
that. Be sure to repeat this service whenever you
have a tire removed or serviced. See Scheduled
Maintenance on page 363 for further information.

Wheel Replacement

Replace any wheel that is bent, cracked or badly
rusted or corroded. If wheel nuts keep coming
loose, replace the wheel. If the wheel leaks
air, replace it.
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.
328
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.
CAUTION:
{
A leaking wheel could fail without warning.
A wheel designed for tubeless tires could
be leaking because it is damaged. Do not
use an inner tube or some other thing to try
to stop the leaking. Get a new wheel of the
proper type.
