Downloaded from www.Manualslib.com manuals search engine on the placard. In addition, for
those owners who prefer the
ut­
most in comfort, the reduced tire
pressures listed on the placard may
be used when loads of
(5 occu­
pants or less) are carried.
The use of improper tire
infla­
tion pressures can adversely affect
tire life and vehicle
perforrilance:
•
Too little air pressure can result
in excessive tire heat, abnormal
tire wear, adverse vehicle
han­
dling 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 preferably
oftener)
or before long trips or
when heavily loaded. The follow­
ing points should be observed
when checking and setting tire
pressures:
<
1. Cold tire pressure ratings are applic­
able 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 (after 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 fecommended
pressures up to a maximum
of 32 psi
cold pressure for load range B tires, or 40 psi for D load range tires. Sustained
speeds above 75 mph are not recom­
mended 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 tires, 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
vehicle, not merely of the tires.
When towing trailers, the
allow­
able passenger 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
vehi­
cle load capacity greater than
specified on the tire placard.
Tire Wear and Rotation-Un­
even or abnormal tire wear is
usually the result of incorrect in­
flation pressure, improper wheel
alignment, wheels being
out-of­
balance, or poor driving habits.
