CHANGING A ROAD WHEEL

Important Information for Lifting
or Jacking

A vehicle jack is not included with your
vehicle. If you are on the road and need to
change a wheel, it is recommended that
you contact the Ford GT Concierge to
obtain roadside assistance. See Special
Notices (page 10).

To avoid damage to your vehicle, use a low
profile hydraulic jack when removing a road
wheel. Only place the jack on one of the
alloy lifting posts when lifting your vehicle.
Do not lift your vehicle on the carbon fiber
panels.

Note: It is recommended that an interface
be used between the alloy lifting point and
the vehicle jack (for example, a hockey puck
or dense rubber pad).

DRIVING AT HIGH SPEED

Tire Pressure - Speeds Greater
Than 165 mph (265 km/h)

WARNING

Always re-inflate tires to
recommended tire pressures before
the vehicle is operated on-road. The

recommended pressure is located on the
tire label or safety certification label,
located on the B-pillar, inside the driver's
door.

Note: When driving over 165 mph
(265 km/h), be sure to check and adjust
your tire pressures accordingly.

Note: If you are not sure about the proper
tire inflation pressures, contact an
authorized dealer or service center.

E247515

Your tires may require additional inflation
pressure for operation at speeds greater
than 165 mph (265 km/h). If this label is
present on your vehicle, you must adjust
the tire pressure accordingly.

TECHNICAL SPECIFICATIONS

Wheel Lug Nut Torque Specifications

WARNING

When you install a wheel, 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. Make sure to secure any fasteners

that attach the rotor to the hub 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 your vehicle
is in motion, resulting in loss of vehicle control, personal injury or death.

Torque specifications are for nut and bolt threads free of dirt and rust. Use only Ford

recommended replacement fasteners.

Retighten the lug nuts to the specified torque within 100 miles (160 kilometers) after any
wheel disturbance (such as tire rotation, changing a flat tire, wheel removal).

E145950

Wheel pilot bore

A

Inspect the wheel pilot bore and
mounting surface prior to installation.
Remove any visible corrosion or loose
particles.

Note: The wheel stud length differs
depending on the wheels equipped. The
hub on carbon fiber wheels require longer
wheel studs due to a thicker hub. If
changing wheel types between alloy and
carbon fiber, in either direction, you must
also change the wheel studs to match the
length required for that wheel type. Also
use the longer studs for the carbon fiber
wheels and then use open lug nuts if
putting alloy wheels back on the car.
