IN CASE OF AN EMERGENCY
Before putting on the wheel, remove any corrosion
on the mounting surfaces with a wire brush or such.
Installation of wheels without good metal-to-metal
contact at the mounting surface can cause wheel nuts
to loosen and eventually cause a wheel to come off
while driving.

7. Reinstall all the wheel nuts finger tight.
Align the holes in the wheel with the bolts. Then lift
up the wheel and get at least the top bolt started
through its hole. Wiggle the tire and press it back
over the other bolts.
Reinstall the wheel nuts and tighten them as much
as you can by hand. Press the tire back and see
if you can tighten them more.
CAUTION
Never use oil or grease on the bolts or nuts.
Doing so may lead to overtightening the nuts
and damaging the bolts. The nuts may loose
and the wheels may fall off, which could cause
a serious accident. If there is oil or grease on
any bolt or nut, clean it.
