Lincoln 1998 Continental - Manual (Page 145)

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
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 must be the same size and grade as the tires you
currently have on your vehicle.
Do not use any type of tire chains on this vehicle. This includes both
conventional and cable-type 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.
