under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perfor-
mance.
The temperature grades are A (the
highest), B and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel. Sustained high tempera-
ture can cause the material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades
B and A represent higher levels of
performance on the laboratory test
wheel than the minimum required by
law.

Proper tire inflation pressure is essential for
the safe and satisfactory operation of your
vehicle. The wrong tire pressure will cause
problems in three major areas:
Safety
Too little pressure increases flexing in the
tire and can cause tire failure. Too much
pressure can cause a tire to lose its ability
to cushion shock. Objects on the road and
potholes could then cause tire damage that
may result in tire failure.
Economy
The wrong tire pressure can cause uneven
wear patterns in the tire tread. These
abnormal wear patterns will reduce the
tread life, and the tire will have to be
replaced sooner.
Too little pressure also makes it harder for
the tire to roll, and this uses up more fuel.
Ride comfort and vehicle stability
The superior riding experience built into
your vehicle partly depends on the correct
tire pressure. Too much pressure gives an
uncomfortable and jarring ride. Too little
pressure feels as if your vehicle is slow to
respond.
Unequal tire pressures can make steering
your vehicle uneven and unpredictable.
The tire pressure for your vehicle under nor-
mal driving conditions is listed on the placard
attached to the driver’s door sill.
(Refer to “Tire and loading information plac-
ard” on page 11-2.)
The recommended inflation pressures under
normal driving conditions should be used for
the tires listed below.
Tire pressures should be checked, and
adjusted if necessary, at least once a month.
Pressures should be checked more often
whenever weather temperatures change
severely, because tire pressures change with
outdoor temperatures. The pressures listed
are always “cold inflation pressure”.
Cold inflation pressure is measured after the
vehicle has been parked for at least three
hours or is driven less than 1 mile (1.6 km)
after having been parked for three hours.
