Increasing the inflation pressure beyond this pressure will not increase
the tire’s load carrying capability.

kPa: Kilopascal, a metric unit of air pressure.
PSI: Pounds per square inch, a standard unit of air pressure.
Cold inflation pressure: The tire pressure when the vehicle has

been stationary and out of direct sunlight for an hour or more and
prior to the vehicle being driven for 1 mile (1.6 km).

Recommended inflation pressure: The cold inflation pressure found

on the Safety Compliance Certification Label or Tire Label located on
the B-Pillar or the edge of the driver’s door.

B-pillar: The structural member at the side of the vehicle behind the

front door.

Bead area of the tire: Area of the tire next to the rim.
Sidewall of the tire: Area between the bead area and the tread.
Tread area of the tire: Area of the perimeter of the tire that

contacts the road when mounted on the vehicle.

Rim: The metal support (wheel) for a tire or a tire and tube assembly

upon which the tire beads are seated.

INFLATING YOUR TIRES

Safe operation of your vehicle requires that your tires are properly
inflated. Remember that a tire can lose up to half of its air pressure
without appearing flat.

Every day before you drive, check your tires. If one looks lower than the
others, use a tire gauge to check pressure of all tires and adjust if
required.

At least once a month and before long trips, inspect each tire and check
the tire pressure with a tire gauge (including spare, if equipped). Inflate
all tires to the inflation pressure recommended by Ford Motor Company.

Use a tire gauge to check the tire inflation pressure, including the spare
(if equipped), at least monthly and before long trips. 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.
