Maintenance
Temperature - A, B & 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 condi-
tions 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. Grades B and A
represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by law.
Low aspect ratio tires
Low aspect ratio tires, the aspect ratio
is lower than 50, are provided for
sporty looks.
Because low aspect ratio tires are
optimized for handling and braking,
their sidewall is a little stiffer than a
standard tire. Also low aspect ratio
tires tend to be wider and consequent-
ly have a greater contact patch with
the road surface. In some instances
they may generate more road noise
compared with standard tires.
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
under-inflation, over-inflation,
or excessive loading, either
separately or in combination,
can cause heat build-up and
possible sudden tire failure.
This may cause loss of vehicle
control resulting in an accident.
WARNING
Because the sidewall of a low
aspect ratio tire is shorter than
a standard tire, the rim of the
wheel and the tire itself is more
easily susceptible to damage.
Use caution when driving and
follow the guidelines below to
help minimize damage to the
wheel and tire:
•
When driving on a rough road
or driving off a road, be care-
ful not to damage the tires
and wheels. After driving,
inspect the tires and wheels.
CAUTION
•
When passing over a pothole,
speed bump, manhole, or
curb stone, drive the vehicle
slowly so as not to damage
the tires and wheels.
•
If the tire is subjected to a
severe impact, we recom-
mend you have the tire and
wheel inspected by an author-
ized HYUNDAI dealer.
•
Inspect the tire condition and
pressure every 3,000 km
(1,800 miles) to prevent tire
damage.
•
It is not easy to recognize tire
damage with your own eyes.
But if there is the slightest hint
of tire damage, have the tire
checked or replaced because
the tire damage may cause air
leakage from the tire.
•
If the tire is damaged by driv-
ing on a rough road, off road,
pothole, manhole, or curb
stone, it will not be covered by
the warranty.
