You are strongly urged to buy a reliable tire pressure gauge, as automatic

service station gauges may be inaccurate. Ford recommends the use of a

digital or dial-type tire pressure gauge rather than a stick-type tire

pressure gauge.

Use the recommended cold inflation pressure for optimum tire

performance and wear. Under-inflation or over-inflation may cause

uneven treadwear patterns.

Always inflate your tires to the Ford recommended inflation pressure

even if it is less than the maximum inflation pressure information found

on the tire. The Ford recommended tire inflation pressure is found on

the Safety Compliance Certification Label (affixed to either the door

hinge pillar, door-latch post, or the door edge that meets the door-latch

post, next to the driver’s seating position), or Tire Label which is located

on the B-Pillar or the edge of the driver’s door. Failure to follow the tire

pressure recommendations can cause uneven treadwear patterns and

adversely affect the way your vehicle handles.

Note: Do not reduce tire pressure to change the ride characteristics of

the vehicle. If you do not maintain the inflation pressure at the levels

specified by Ford, your vehicle may experience a condition known as

“shimmy”. Shimmy is a severe vibration and oscillation in the steering

wheel after the vehicle travels over a bump or dip in the road that does

not dampen out by itself. Shimmy may result from significant

under-inflation of the tires, improper tires (load range, size, or type), or

vehicle modifications such as lift-kits. In the event that your vehicle

experiences shimmy, you should slowly reduce speed by either lifting off

the accelerator pedal or lightly applying the brakes. The shimmy will

cease as the vehicle speed decreases.

Maximum Permissible Inflation Pressure is the tire manufacturer’s

maximum permissible pressure and/or the pressure at which the

maximum load can be carried by the tire. This pressure is normally

higher than the manufacturer’s recommended cold inflation pressure

which can be found on the Safety Compliance Certification Label (affixed

to either the door hinge pillar, door-latch post, or the door edge that

meets the door-latch post, next to the driver’s seating position), or Tire

Label which is located on the B-Pillar or the edge of the driver’s door.

The cold inflation pressure should never be set lower than the

recommended pressure on the Safety Compliance Certification Label or

Tire Label.
