A. T: Indicates a type of tire, designated
by the Tire and Rim Association, that is
intended for temporary service on cars,
sport utility vehicles, minivans and light
trucks.
B. 145: Indicates the nominal width of
the tire in millimeters from sidewall edge
to sidewall edge. In general, the larger
the number, the wider the tire.
C. 80: Indicates the aspect ratio which
gives the tire's ratio of height to width.
Numbers of 70 or lower indicate a short
sidewall.
D. D: Indicates a diagonal type tire.
R: Indicates a radial type tire.
E. 16: Indicates the wheel or rim
diameter in inches. If you change your
wheel size, you will have to purchase
new tires to match the new wheel
diameter.
Location of the Tire Label
You will find a Tire Label containing tire
inflation pressure by tire size and other
important information located on the
B-Pillar or the edge of the driver's door.
See Load Carrying (page 212).
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.
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.
WARNING
Under-inflation is the most common
cause of tire failures and may result
in severe tire cracking, tread separation
or blowout, with unexpected loss of
vehicle control and increased risk of
injury. Under-inflation increases sidewall
flexing and rolling resistance, resulting
in heat buildup and internal damage to
the tire. It also may result in unnecessary
tire stress, irregular wear, loss of vehicle
control and accidents. A tire can lose up
to half of its air pressure and not appear
to be flat!
