2012 FORD MUSTANG Boss 302 Supplement Manual

•When replacing tires, the only way to ensure 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.
WARNING:Snow tires must be the same size, load index, speed
rating as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and
performance of your vehicle, which could result in an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
Additionally, the use of non-recommended tires and wheels could
cause steering, suspension, axle or transfer case/power transfer unit
failure.
Winter driving
The original equipment tires on your Boss302 are designed for high
performance steering and handling. 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.
Do not operate your vehicle above posted speed limits and never
perform high speed driving with winter tires, even in clear, dry driving
conditions.
Tire rotation
Because your vehicle is equipped with unique larger tires on the rear
wheels, you can only rotate the tires side to side. You must not rotate
tires in a crisscross pattern or front to rear. If you notice that the tires
wear unevenly, have them checked.
The tires on your Boss302 should be rotated every 5,000 miles
(8,000 km). This will help your tires wear more evenly, providing better
tire performance and longer tire life.

problem involved before tire rotation.

and adjusted to the vehicle requirements.
