may depart significantly from the norm due to variations
in
driving habits, service practices and differences
in
road characteristics and climate.
Traction
--
A,
€3,
C
The traction grades,
from
highest
to
lowest, are
A,
B,
and
C,
and they 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.
Warning: The traction grade assigned to this tire is based
on braking (straight ahead) traction tests and does not
include cornering (turning) traction.
Temperature
--
A,
€3,
C
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 conditions on
a specified indoor laboratory
test wheel. Sustained high temperature 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
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.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading,
either
separately
or
in
combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire
life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However,
if
you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset.
If
you notice your vehicle
vibrating when driving on
a
smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded.
If
wheel nuts keep coming loose, the wheel,
wheel
bolts
and wheel nuts should be replaced.
If
the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
dealer
if
any of these conditions exist.
Your
dealer will know the kind of wheel you need.
