Wheels and Tires
• Inspect your tires for damage on a regular basis. If a tire is damaged,
replace it immediately.
• Proper suspension alignment is critical for maximum performance and
optimal tire wear. If you notice uneven tire wear, have your alignment
checked.
• When replacing tires, the only way to maintain original performance is
to use the original equipment tire. If a different summer tire is used, it
should be the same size, speed rating and load rating as the originally
equipped tire. Tires should be replaced as a set of four. Never mix tire
brands or models.
TIRE PRESSURE
• For tire pressures, see the placard located on the B-pillar inside the
driver's door.
• Always maintain your tire pressures according to the tire information
placard on the driver's door jamb, using an accurate gauge.
• Tire pressures are specified "cold" and should be checked after the
vehicle has been parked for at least 3 hours. Do not reduce pressure
of warm tires.
• Check your tire pressure often to maintain it properly. Tire pressure
can diminish over time and fluctuate with temperature.
WINTER DRIVING
The original equipment tires on your ST vehicle are designed for
maximum performance in dry and wet summer conditions. They are not
designed for winter use on ice or snow and cannot be used with snow
chains. Ford does not recommend using the original equipment tires
when temperatures drop to approximately 40°F (5°C) or below
(depending on tire wear and environmental conditions) or in snow/ice
conditions. If you will be operating your vehicle in these conditions,
winter or all-season tires must be used.
• Even with clear, dry driving conditions do not operate your vehicle
above posted speed limits or perform high speed maneuvers with
winter tires.
• Do not use tire chains on the original wheels and tires of your vehicle.
The use of any type of tire chain on these tires may damage your
vehicle.
