Turn the ratchet to the left to lower the spare tire to the
ground. If you are changing a flat rear tire and the
vehicle is already jacked up, use the jack handle and
extension to hook the cable. Then pull the spare from
beneath the vehicle. If the retainer pulls out, hook the
inside of the wheel and pull the spare tire out from under
the vehicle.
When the tire has been lowered, tilt the retainer at the
end of the cable and pull it through the wheel opening.
