僅 Low Aspect Ratio Tire - Kia EV6 Manual

Maintenance
WARNING
僅 The traction grade assigned to this
tire is based on straight ahead brak-
ing traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction char-
acteristics.
僅 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 build-up
in tire and sudden tire failure. This can
cause loss of vehicle control and seri-
ous injury or death.
Tread wear
The tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one-and-a-half times (1½) as well
on the government course as a tire
graded 100.
The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart sig-
nificantly from the norm due to varia-
tions in driving habits, service practices
and differences in road characteristics
and climate.
The tires available as standard or
optional equipment on your vehicle may
vary with respect to grade.
Traction - AA, A, B & C
The traction grades, from highest to low-
est, are AA, A, B and C. Those grades
represent the tire's ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction per-
formance.
Temperature -A, B & C
The temperature grades are A (the high-
est), 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 speci-
fied indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
perature can lead to sudden tire failure.
Grades B and A represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
Low aspect ratio tire (if
equipped)
Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided for
sporty looks.
Because the low aspect ratio tires are
optimized for handling and braking, it
may be more uncomfortable to ride in
and there is more noise compare with
normal tires.
