TREADWEAR
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled con-
ditions on a specified government test
course. For example, a tire graded
150 would wear one and one-half
times as well on the government
course as a tire graded 100. The rela-
tive performance of tires depends
upon the actual conditions of their
use, however, and may depart signifi-
cantly from the norm due to variations
in driving habits, service practices, and
differences in road characteristics and
climate.
TRACTION GRADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on speci-
fied 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 straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
TEMPERATURE GRADES
WARNING!
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Exces-
sive speed, under-inflation, or exces-
sive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
STORING THE VEHICLE
If you are storing your vehicle for more than three
weeks, we recommend that you take the following steps
to minimize the drain on your vehicle's battery:
•
Disconnect the negative cable from battery.
•
Before you store your vehicle or keep it out of ser-
vice (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system
is started again.
BODYWORK
PROTECTION FROM ATMOSPHERIC
AGENTS
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make
roads passable in snow and ice and those that are
sprayed on trees and road surfaces during other sea-
sons are highly corrosive to the metal in your vehicle.
Outside parking, which exposes your vehicle to airborne
contaminants, road surfaces on which the vehicle is
operated, extreme hot or cold weather and other
extreme conditions will have an adverse effect on paint,
metal trim, and underbody protection.
The following maintenance recommendations will
enable you to obtain maximum benefit from the corro-
sion resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
The most common causes are:
•
Road salt, dirt and moisture accumulation.
•
Stone and gravel impact.
•
Insects, tree sap and tar.
•
Salt in the air near seacoast localities.
•
Atmospheric fallout/industrial pollutants.
