NOTE: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. If you need to use snow tires and chains, it is
recommended that steel wheels are used of the same size and
specifications as those originally installed.
Follow these guidelines when using snow tires and chains:
• Do not use tire chains on aluminum wheels. Chains may chip the
wheels.
• Use only SAE Class S chains.
• Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
Drive cautiously. If you hear the cables rub or bang against the
vehicle, stop and retighten them. If this does not work, remove
the cables to prevent vehicle damage.
• 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.
