Maintenance
Temperature - A, B & C
CAUTION
The temperature grades are A (the
highest), then B and C representing the
tyre’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 tyre to degenerate
and reduce tyre life, and excessive
temperature can lead to sudden tyre
failure. Grades B and A represent high-
er levels of performance on the labora-
tory test wheel than the minimum re-
quired by law.
Because the sidewall of a low aspect
ratio tyre is shorter than a standard
tyre, the rim of the wheel and the tyre
itself is more easily susceptible to
damage. Use caution when driving
and follow the guidelines below to
help minimise damage to the wheel
and tyre:
• When driving on a rough road or
driving off a road, be careful not to
damage the tyres and wheels. Af-
ter driving, inspect the tyres and
wheels.
• When passing over a pothole,
speed bump, manhole, or curb
stone, drive the vehicle slowly so
as not to damage the tyres and
wheels.
WARNING
The temperature grade for this tyre
is established for a tyre that is prop-
erly inflated and not overloaded. Ex-
cessive speed, under-inflation, over-
inflation, or excessive loading, either
separately or in combination, can
cause heat build-up and possible
sudden tyre failure. This may cause
loss of vehicle control resulting in
an accident.
• If the tyre is subjected to a severe
impact, we recommend you have
the tyre and wheel inspected by a
HYUNDAI authorised repairer.
• Inspect the tyre condition and
pressure every 1,800 miles (3,000
km) to prevent tyre damage.
• It is not easy to recognise tyre
damage with your own eyes. But if
there is the slightest hint of tyre
damage, have the tyre checked or
replaced because the tyre damage
may cause air leakage from the
tyre.
Low aspect ratio tyres
Low aspect ratio tyres, the aspect ratio
is lower than 50, are provided for sporty
looks.
• If the tyre is damaged by driving
on a rough road, off road, pothole,
manhole, or kerb stone, it will not
be covered by the warranty.
Because low aspect ratio tyres are opti-
mised for handling and braking, their
sidewall is a little stiffer than a standard
tyre. Also low aspect ratio tyres tend to
be wider and consequently have a
greater contact patch with the road sur-
face. In some instances they may gen-
erate more road noise compared with
standard tyres.
