Low Aspect Ratio Tire - Hyundai i20 Owner's Manual

Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those grades
represent the tire's ability to stop on wet
pavement measured under controlled
conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
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 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. Grades B and A represent higher
levels of performance on the laboratory
test wheel than the minimum required
by law.
WARNING
Tire temperature
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive
loading, either separately or in
combination, can cause heat build-up
and sudden tire failure. This can cause
loss of vehicle control and serious
injury or death.

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.
