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
A low aspect ratio tire, of which the
aspect ratio is lower than 50, is
designed for a sporty-look vehicle.
The low aspect ratio is to optimize
handling and braking. Thus, it may
be uncomfortable to ride and it may
generate noises, in comparison with
a normal tire.
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
The side wall of a low aspect
ratio tire is shorter than the nor-
mal one. Thus, the low-aspect
wheel and tire are easily dam-
aged. Follow the below instruc-
tions.
•
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.
•
When passing over a pothole,
speed bump, manhole, or
curb stone, slowly drive the
vehicle not to damage the
tires and wheels.

CAUTION

•
When there is an impact on a
tire, inspect the tire condition.
Or, contact an authorized
HYUNDAI dealer.
•
Inspect the tire condition and
pressure every 3,000 km
(1,800 miles) to prevent a tire
damage.
•
It is difficult to recognize a tire
damage only with your eyes.
When there is a slight hint of a
tire damage, check and replace
the tire to prevent the damage
caused by air leakage.
•
When a tire is damaged while
driving on a rough road, off a
road, or over obstacles, such
as a pothole, manhole, or curb
stone, your warranty does not
cover the damage.
•
The tire information is speci-
fied on the tire side wall.
