Treadwear, Traction and Temperature GradesTr e a d w e a r
The treadwear grade is a comparative rating based on the
wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire
graded 150 would wear one and one-half (1
1/2) times as
well on the government course as a tire graded 100. The rel-
ative performance of tires depends upon the actual condi-
tions of their use, however, and may depart significantly
from the norm due to variations in driving habits, service
practices and differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B
and C. Those grades represent the tire’s ability to stop on
wet pavement as measured under controlled conditions on
specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Te m p e r a t u r e
The temperature grades are A (the highest), B and C, repre-
senting 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 temperature can cause the material of the tire to degen-
erate and reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard No.
109. Grades B and A represent higher levels of performance
on the laboratory test wheel than the minimum required by
law.
Tire inflation pressures
N00939300815
Proper tire inflation pressure is essential for the safe and satis-
factory 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 lit-
tle 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 normal driving condi-
tions is listed on the placard attached to the driver’s door sill.
(Refer to “Tire and loading information placard” on page 9-4.)

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.
Cold inflation pressure must not go above the maximum values
molded into the tire sidewall. After driving several miles, your
tire inflation pressure may increase 2 to 6 psi (14 to 41 kPa)
from the cold inflation pressure. Do not let air out of the tires to
get back to the specified cold pressure, or your tires will be too
low.Check your tires each time you refuel. If one tire looks lower
than the others, check the pressure for all of them.
You should also take the following safety precautions:
Keep your tires inflated to the recommended pressures.
(See the tire and loading information placard attached to
the driver’s door sill.)
Stay within the recommended load limits.
Make sure that the weight of any load in your vehicle is
evenly distributed.
Drive at safe speeds.
After filling your tires to the correct pressure, check them
for damage and air leaks. Be sure to reinstall the caps on
the valve stems.
