The tires on your vehicle have all weather treads to
provide traction in rain and snow. However, in some
climates, you may need to use snow tires and
chains. Use chains on the tires only in an emergency
or if the law requires them.
Follow these guidelines when using snow tires and
chains:
²Chains may damage aluminum wheels.
²Use only Cable Type chains with size P225/55R16
or 245/45ZR17 tires. Use of SAE Class S chains
may damage vehicle.
²SAE Class S chains may be used on P205/65R15
tires.
²Install chains securely, verifying that the chains do
not touch any wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or
bang against your vehicle, stop and re-tighten the
chains. If this does not work, remove the chains
to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
²The suspension insulation and bumpers will help
prevent vehicle damage. Do not remove these
components from your vehicle when using snow
tires and chains.

proper conversion may damage the effectiveness of
your emission control system and may cause engine
knocking or serious engine damage. Ford Motor

damage caused by use of improper fuel.
In the United States, using leaded fuel may also
result in difficulty importing your vehicle back into
