6. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.

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.
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 loosen 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.
