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.
Recommended Tire Pressures
and 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 the 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.

and may result in severe tire
cracking, tread separation, or
blowout, with unexpected loss of
vehicle control and increased risk
of injury. Under-inflation increase
sidewall flexing and rolling
resistance, resulting in heat
build-up 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 flat.
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
