The use of improper tire
infla
tion pressures can adversely affect
tire life and vehicle performance:
• Too little air pressure can result
in excessive tire heat, abnormal
tire wear, adverse handling and
reduced fuel economy.
• Too much air pressure can re
sult in abnormal tire wear, ad
verse vehicle ride and handling,
and increased susceptibility to
damage by road impacts.
Tire pressures should be
checked when the tires are "cold"
at least once a month (and pref
erably oftener) or before long
trips or when heavily loaded. The
following points should
be ob
served when checking and setting
tire pressures:
1. Cold tire pressure ratings are applicable when a vehicle has been Inoperative for 3 hours or more, or driven less
than 1 mile.
2. Tire Inflation pressure may Increase as
much as 6 pounds per square inch (psi)
when hot (aHer vehicle has been driven
10 miles or at speeds of more than 60 miles per hour). Do not "bleed" or reduce pressures when tires are hot from
driving.
3. For continuous high speed operation
(over 75 mph), Increase tire inflation
pressure 4 psi above the recommended
pressures up
to a maximum of 32 psi
cold pressure for load range B tires, 36
psi for load range C tires, or 40 psi for D load range tires. Sustained speeds
above 75 mph are not recommended
when the 4 psi adjustment would require pressures greater than the above
maximum pressures.
4. Always use a tire pressure gauge when
checking pressures as the appearance
of a tire can be deceiving. For example,
radial ply fires, In comparison with bias
ply tires at the same pressure, may have
the appearance of being under-inflated.
Vehicle Loading -Do not load
your vehicle beyond the vehicle
capacity (total pounds) shown on
the tire placard. This figure
repre
sents the design capacity of the ve
hicle, not merely of the tires.

When towmg trailers, the allow
able pasenger and cargo load
must be reduced by an amount
equal to the trailer tongue load on
the trailer hitch.
(See "Trailer
Hauling"
in Section 1 of this man
ual.) Station wagon loads should
be distributed
as far forward as
possible. Vehicles equipped with
luggage racks do not have a
ve
hicle load capacity greater than
specified on the tire placard.
Tire Wear and Rotation -Un
even or abnormal tire wear is usu
ally the result of incorrect inflation
pressure, improper wheel
align
ment, wheels being out-of-balance,
or poor driving habits.
Underin
flation, incorrect toe or camber
and fast cornering produce
differ
ent types of abnormal wear which
can be diagnosed by your dealer.
