Snow Tires And Chains - Ford Thunderbird Owner's Manual

The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive
loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
Driving too fast for conditions creates the
possibility of loss of vehicle control.
Driving at very high speeds for extended
periods of time may result in damage to
vehicle components.

Snow Tires and Chains

The tires on your vehicle have all-weather treads
that provide traction in rain or snow. However,
during the winter months in some climates, you
may need to use snow tires and occasionally
chains for your tires.
Snow tires must be the same size and
grade as the tires you currently have on
your vehicle.
Use chains on the tires only in an emergency or
if the law requires them where you live. If you
choose to use chains on your vehicle's tires, be
aware of the following:
Make sure the chains are the right size for
your tires. Use only SAE Class "S" chains.
Other types may damage your vehicle.
