Inflation
Pressure
To ensure the proper tire inflation
pressure for your particular require-
ments, follow the recommendations on
the tire placard affixed to the left front
door of your vehicle. A typical placard
is shown here. The placard on the door
specifies the size and ply of the tires
installed on your vehicle, plus thE'
recommended tire pressures, and ca-
pacity of your vehicle.
The tire inflation pressures shown
on the tire placard have been selected
to provide you with the best tire life
and riding comfort over the full range
of normal driving conditions.
The use of improper tire inflation
1. Tire inflation pressures may increase
as much as six (6) pounds per square
inch (PSI) when hot.
2. For continuous high speed operation
(over 75 MPH) increase tire inflation
pressure 4 pounds per square inch
over the recommended pressures up
to a maximum of 32 pounds per square
inch co.1d for load range B tires. Sus-
tained speeds above 75 mph are not
recommended when the 4 pounds per
square inch adjustment would require
pressures greater than the maximums
stated above.

pressures can cause a serious reduction
in tire life. Inflation pressures should be
checked at least once a month (and
preferably oftener) to insure that the
right amount of air is contained in the
tires. Too little air pressure allows
abnormal deflection of the tire causing
excessive operating temperatures,
while too much air pressure prevents
normal deflection, making the cord
body more vulnerable to road impacts.
Use of optional inflation is allowable
only with a reduced load (one to five
passengers). When operating at loads
greater than the optional reduced load,
the inflation pressure must be in-
creased to the standard inflation for
full rated loads.
3. Cold tire inflation pressure: after vehi-
cle has been inoperative for three (3)
hours or more, or driven less than one
(1) mile.
Hot tire inflation pressure: after vehicle
has been driven ten (10) miles or more
at 60-70 MPH.
4. Vehicles with luggage racks do not
have a vehicle load limit greater than
specified.
5. When towing trailers, the allowable
passenger and cargo load must be
reduced by an amount equal to the
trailer tongue load on the trailer hitch.
