Operating at high speeds
Your SVT vehicle is capable of high speeds and is equipped with tires
rated for the vehicle’s maximum speed. Remember to drive safely, obey
all traffic laws and only operate your SVT vehicle at high speeds at
locations equipped and designed to do so safely. Before operating your
vehicle at high speeds:
•Ensure correct tire pressures (seeTiresin this supplement).
•Inspect wheels and tires for wear and damage. Replace any damaged
wheels or tires.
•Do not operate your vehicle at high speeds with more than two
passengers or while carrying cargo.
Wheel lug nut torque specifications
Retighten the lug nuts to the specified torque at 500 miles (800 km)
after any wheel disturbance (tire rotation, changing a flat tire, wheel
removal, etc.).
Bolt size Wheel lug nut torque*
lb.ft. N•m

* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
WARNING:When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake drum or
brake disc that contacts the wheel. Ensure that any fasteners that
attach the rotor to the hub are secured so they do not interfere with
the mounting surfaces of the wheel. Installing wheels without correct
metal-to-metal contact at the wheel mounting surfaces can cause the
wheel nuts to loosen and the wheel to come off while the vehicle is in
motion, resulting in loss of control.

•Extra caution should be taken when operating the vehicle near its
maximum load, including assuring proper tire pressure and reducing
speeds.
•Extra caution should be taken when operating on rough roads to avoid
impacts that could cause tire damage.
•In the event that 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.
•Rotate tires as recommended in the following sectionTire rotation.
•When replacing tires, the only way to assure original performance is to
use the original equipment tire. If a different tire is used, it should be
the same size, speed rating and load rating and be replaced as a set of
four. Never mix tire brands.
Winter driving
The original equipment tires on your SVT 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. If you will be operating your vehicle in these conditions, winter
or all-season tires must be used.
•Use winter tires on all four wheels and use P255/45R18 tires with a
“V” speed rating and a 93 load index or higher.
•Winter tires must be of the proper speed and load ratings.
•Be aware that winter or all-season tires will not perform as well as the
original equipment tire in dry and wet conditions. Expect handling,
steering and braking to be degraded.
•Do not use a winter tire with less than a “V” speed rating, and even
with clear, dry driving conditions do not operate your vehicle above
posted speed limits while using winter tires. Never perform high speed
driving with winter tires.
