Tire Information
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.
IMPORTANT TIRE INFORMATION
Your vehicle is equipped with unique wheels and tires designed to
enhance performance. To continue providing this performance, extra
care must be taken when operating and maintaining your vehicle.

Tires
Your Boss 302 is equipped with low profile, high performance tires that
are designed to optimize the car's driving dynamics. These tires are not
optimized for off-road or winter (snow or cold weather) performance,
and their ride, noise and wear characteristics are different than
non-performance tires. Also, because of their lower profile, the tires are
more susceptible to damage due to potholes and rough roads. To ensure
that your tires perform as intended, it is important that you maintain
your tires properly.
• The Boss 302 and Boss 302 with Laguna Seca Package original
equipment tires are optimized for maximum steering and handling
performance. Ford does not recommend using these tires in cold
temperatures of approximately 40°F (5°C) and below (depending on
tire, surface and weather conditions). See your Ford dealer for
recommended tires in these conditions.
