Tire Chain Usage

When chains are to be used, most current vehicles require SAE Class "S" or SAE Class "U" tire chains. These may also be designated as 1100 Series, Type "PL," 1200 Series, Type "P," or 1800 Series Lug Reinforced 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 size to ensure proper fit when installed. Therefore, be sure to purchase the correct chains for the tires on which they are to be used. Rubber adjusters should not be used to take up slack or clearance in chains that are loose due to incorrect size.

Always follow the chain manufacturer's installation instruction.
Use of chains may adversely affect handling. When using chains:
a. Ensure that the vehicle is designed for chain clearance.
b. Adjust speed to road conditions.
c. Avoid sharp turns.
d. Avoid locked-wheel braking in general, to help prevent chain damage to the vehicle.
e. Install the chains on the drive tires as tightly as possible, then tighten them again after driving 0.4 to 0.8 kilometer (1/4 to 1/2 mile). The use of chains on the non-drive tires is not recommended; the chains may contact and possibly damage the vehicle. If chains are used on the non-drive tires, make sure there is enough clearance.
f. Do not exceed 70 km/h (45 mph) or the chain manufacturer's speed limit, if lower.
g. Drive in a restrained manner and avoid large bumps, potholes, severe turns, and other maneuvers that could cause the tires to bounce up and down.
h. Follow any other instructions of the chain manufacturer that do not agree with the above.
