Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
Failure to follow these precautions may adversely affect the
handling of the vehicle and make it easier to lose control and roll
over.
Tires that are larger or smaller than your vehicle’s original tires may also
affect the accuracy of your speedometer.
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. If you need to use snow tires and chains, you must
install steel wheels of the same size and specifications as those originally
installed.
Follow these guidelines when using snow tires and chains:
• 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 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.
