2003 FORD THUNDERBIRD tires

Tire rotation
Because your vehicle’s tires perform different jobs, they often wear
differently. To make sure your tires wear evenly and last longer, rotate
them as indicated in the scheduled maintenance guide. If you notice that
the tires wear unevenly, have them checked.
•Four tire rotation
Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
When replacing full size tires, never mix radial bias-belted, or
bias-type tires. Use only the tire sizes that are listed on the
Certification or Tire Label. Make sure that all tires are the same size,
speed rating, and load-carrying capacity. Use only the tire combinations
recommended on the label. If you do not follow these precautions,
your vehicle may not drive properly and safely.
Make sure that all replacement tires are of the same size, type,
load-carrying capacity and tread design (e.g.,“All Terrain”,
“Touring”, etc.), as originally offered by Ford.
Maintenance and Specifications
181

Failure to follow these precautions may adversely affect the
handling of the vehicle, and increase the risk of loss of vehicle
control, vehicle rollover and/or personal injury.
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.
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
Driving at very high speeds for extended periods of time may result in
damage to vehicle components.
The tires on your vehicle have all-weather treads that provide traction in
rain or snow.
The use of snow cables is not recommended for this vehicle, as damage
to your vehicle may occur under extreme handling or rough road
conditions. However, if you choose to operate the vehicle with snow
cables, avoid these conditions and follow the manufacturer’s
recommendations.
Do not use any type of tire chains, as this will likely cause damage to
your vehicle.
