GMC T-Series 2007, Owner'S Manual, Page: 260 / 356

First, use these pictures to decide what kind of
wheels you have.
Then, refer to the following steps for the wheels
you have.
Hub-Piloted Wheels, 8-Hole or 10-Hole
The studs and nuts used with these wheels have
right-hand threads.
1. With intermittent pilot pads, position a
pad at 12 o’clock to center the wheel
and reduce run-out.
2. Put the tire and rim assembly on the axle hub.
Install the outer rear tire and rim assembly so
that its valve stem is exactly opposite the
valve stem on the inner tire and rim assembly.
3. Put on the wheel nuts.
4. Finger-tighten the nuts.
5. Oil the surfaces (B)
between the nuts (C)
and washers (A).
Do not oil the studs
or the threads of
the nut.
