Installation, tightening and alignment

8–lug wheel
10–lug wheel
When installing wheels, be certain that the threads on studs and nuts are
clean to permit correct torquing of nuts. The mounting surfaces of rims,
wheels, spacer rings and clamps must be free of dirt, rust, lubricants or
damage.
Use a wire brush to clean the mounting contact surfaces. Do not use
lubricant on threads.
After the rim or wheel has been properly tightened, it should be checked
for alignment. Rotate the wheel with a piece of chalk attached to a
steady, firm surface, and placed to just barely clear the outside surface of
the tire bead seat. This procedure will point out the high spot. A high
spot does not necessarily mean that the lug nuts have been unevenly
tightened. This condition or misalignment could be caused by a bent
wheel.
Checking the alignment of the wheel/rim installation is more important
on cast spoke rims since the rims can be drawn out of alignment when
improperly tightened. Use the following installation procedures.
