Notice: Tire chains should not be used with P245/50ZR16 or P235/55R16 tires.
The chains could damage the vehicle. Tire chains are only recommended for
emergency use or when required by law.
Due to limited tire-to-body clearance on certain vehicles,
tire chain usage recommendations are published in the Owner's Manual. When
chains are needed, most current GM vehicles require SAE Class S tire chains.
These are also designated as 1100 Series, Type PL tire chains. These chains
are specially designed to limit the fly off effect that occurs when the tire
and the wheel rotate.
Manufacturers of tire chains have a specific chain size for each tire
and wheel in order to ensure proper fit when installing the chains. Therefore,
the vehicle owner must obtain specific chains for the tires and wheels on
which the chains are to be used. Do not use rubber adjusters in order to
take up the slack or clearance in chains which are loose due to incorrect
size. Always follow the chain manufacturer's installation instructions.
The use of chains may adversely affect vehicle handling. When driving
with chains installed, remember the following driving tips:
| • | Adjust your speed to the road conditions |
Adhere to the following tips in order to help prevent chain damage to
the vehicle:
| • | Install chains on rear tires and wheels as tightly as possible.
Then tighten the chains again after driving 0.4-0.8 km (¼-½ mi).
The use of chains on front tires and wheels is not recommended. The chains
may contact and possibly damage the vehicle if the chains are used on front
wheels. If you do use chains on front tires and wheels, allow for enough
clearance. |
| • | Do not exceed 70 km/h (45 mph), or the chain manufacturer's
speed limit, whichever is lower. |
| • | Drive in a restrained manner and avoid the following road conditions: |
| - | Other maneuvers that may cause tires and wheels to bounce up and
down |
| • | Follow any other instructions of the chain manufacturer which
do not disagree with this section. Additional specific information is published
in the Owner's Manual. |
