Tire Chain Usage

Due to limited tire-to-body clearance on certain vehicles, the Owner's Manual publishes tire chain usage recommendations. When chains are used, most current GM vehicles require SAE Class S tire chains. These may also be designated as 1100 Series, Type PL tire chains. These chains are specially designed to limit the fly off effect that occurs when the wheel rotates.

Manufacturers of tire chains have a specific chain size for each tire in order to ensure proper fit when installed.
^ Always purchase the correct chains for the tires on which they are to be used.
^ Do not use rubber adjusters to take up slack or clearance in chains which are too loose due to incorrect size.
^ Always follow the chain manufacturer's installation instructions.

Use of chains may adversely affect vehicle handling.

When using chains, drivers must be aware of the following:
^ Adjust speed to road conditions
^ Avoid sharp turns
^ Avoid locked-wheel braking
