Using Winter Tires - Ford FIESTA ST 2018 Supplement Manual

• If you encounter an abnormally harsh
impact, inspect your tires for damage.
• 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. Replace
tires 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
door.
• Always maintain your tire pressures
according to the tire information
placard on the driver door jamb, using
an accurate gauge.
• Tire pressures are specified cold. Check
them after the vehicle has been parked
for at least three 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.
Tire Pressure for High Speed Usage
If you are operating your ST vehicle in areas
that allow high-speed driving over 100 mph
(160 km/h), increase the tire pressure in
all four tires by 3 psi above the pressures
listed on the Tire Pressure placard located
on the driver side b-pillar.

Wheels and Tires
Optional All-Season Tires
Your ST vehicle may come equipped with
an optional All-Season performance tire.
This choice will provide the benefit of four
season mobility without requiring the
installation of winter tires. It is important
to realize that ultimate summer
performance will be reduced relative to
the standard equipment summer only tire.
Additionally, ultimate winter traction and
control will be less than a dedicated winter
tire would provide. If you drive during the
winter months in areas with heavy snowfall
or hilly terrain, you may wish to install a
dedicated winter tire if ultimate traction
and control are desired.

USING WINTER TIRES

If so equipped, the original equipment
summer-only 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 and ice conditions.
You must use winter or all-season tires if
you will be operating your vehicle in these
conditions.

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.
