Tires, Replacement Requirements
Do not use a size and type of tire and wheel other than that
originally provided by Ford Motor Company because it can affect
the safety and performance of your vehicle, which could result in an
increased risk of loss of vehicle control, vehicle rollover, and/or serious
personal injury or death.
Make sure all road tires and road wheels on the vehicle are of the same
size, type, tread design and load carrying capacity (for information on
the spare tire, refer toChanging the Tiresin theRoadside
emergencieschapter). If you have questions regarding tire replacement,
see an authorized Ford or Lincoln/Mercury dealer.
If you nevertheless decide to equip your four–wheel drive for off-road
use with tires larger than what Ford Motor Company recommends, you
should not use these tires for highway driving.
If you use any tire/wheel combination not recommended by Ford Motor
Company, it may adversely affect vehicle handling and could cause
steering, suspension, axle or transfer case failure as well as the increased
risk of loss of vehicle control.
Do not use“aftermarket lift kits”or other suspension modifications,
whether or not they are used with larger tires and wheels.
These“aftermarket lift kits”could adversely affect the vehicle’s handling
characteristics, which could lead to loss of vehicle control or rollover and
serious injury.
Tires can be damaged during off-road use. For your safety, tires that are
damaged should not be used for highway driving because they are more
likely to blow out or fail.
You should carefully observe the recommended tire inflation pressure
found on the safety compliance certification label attached to the left
front door latch post pillar (a label may also be found on the fuel cap
filler door). Failure to follow tire pressure recommendations can
adversely affect the way your vehicle handles. Do not exceed the Ford
Motor Company recommended pressure even if it is less than the
maximum pressure allowed for the tire.
