SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
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.
Follow these guidelines when using snow tires and chains:
•
Use only cable type chains or chains offered by Ford as an accessory
or equivalent. Other conventional link type chains may contact and
cause damage to the vehicle’s wheel house and/or body.
•
Do not install chains on the front wheels. Chains on the front wheels
may interfere with suspension components.
•
Chains are not recommended for use on the optional P275/65R18 tire.
•
Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•
Drive 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.
•
If possible, avoid fully loading your vehicle.
•
Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
•
The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
•
Do not exceed 48 km/h (30 mph) with tire chains on your vehicle.
