Raise the vehicle until the tire is
slightly raised off the ground.
Remove all the wheel nuts and the
tire.
When resting the tire on the
ground, place the tire so that the
wheel design faces up to avoid
scratching the wheel surface.
Remove any dirt or foreign matter
from the wheel contact surface.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, and the tire may come off
the vehicle.
