vehicle is stable and that there is no
chance for movement or slippage.

lug nut wrench and remove them with
your fingers. Remove the wheel from
the studs and lay it flat on the ground
out of the way. Remove any dirt or
debris from the studs, mounting
mounting surfaces and wheel.
WARNING
Wheels may have sharp edges. Handle
them carefully to avoid possible severe
injury. Before putting the wheel into
place, be sure that there is nothing on
the hub or wheel (such as mud, tar,
gravel, etc.) that interferes with the
wheel from fitting solidly against the
hub.
If there is, remove it. If there is not
good contact on the mounting surface
between the wheel and hub, the wheel
nuts could come loose and cause the
loss of a wheel. Loss of a wheel may
result in loss of control of the vehicle.
This may cause serious injury or death.
