Temperature Grades
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 vehicle 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.
STORING THE VEHICLE
If you are storing your vehicle for more than
21 days, we recommend that you take the
following steps to minimize the drain on your
vehicle's battery:
Disconnect the negative cable from battery.
Any time you store your vehicle or keep it out
of service (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 geographic locations and usage. Chemicals
that make roads passable in snow and ice and
those that are sprayed on trees and road
surfaces during other seasons 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 corrosion resistance built into your vehicle.
WARNING!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.
