Tire Replacement Requirements
Your vehicle is equipped with tires designed to provide a safe ride and handling capability.
Only use replacement tires and wheels that are the same size
and type (such as P-metric versus LT-metric or all-season versus
all-terrain) as those originally provided by Ford. The recommended tire
and wheel size may be found on either the Safety Compliance
Certification Label or the Tire Label which is located on the B-Pillar or
edge of the driver’s door. If this information is not found on these
labels then you should consult your Ford Dealer. 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. If
you have questions regarding tire replacement, see an authorized
dealer.
When mounting replacement tires and wheels, you should not
exceed the maximum pressure indicated on the sidewall of the tire
to set the beads without additional precautions listed below. If the beads
do not seat at the maximum pressure indicated, re-lubricate and try again.
If a pressure in excess of the maximum pressure indicated is required, the
following additional precautions must be taken to protect the person
mounting the tire:
First check to insure that you have the correct tire and wheel size. For
mounting pressures up to 20 psi greater than the maximum pressure on the
tire sidewall: When inflating the tire:
1. First again lubricate the tire bead and wheel bead seat area
2. Stand at a minimum of 12 feet away from the tire wheel assembly
3. Use both eye and ear protection
For a mounting pressure more than 20 psi greater than the maximum pressure, a Ford Dealer or other tire
service professional should do the mounting.
Always inflate steel carcass tires with a remote air fill with the person inflating standing at a minimum of 12 ft.
away from the tire wheel assembly.
