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.
