These grades are molded on the
side-walls of passenger vehicle
tyres. The tyres available as standard
or optional equipment on your vehi-
cle may vary with respect to grade.
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tyre's ability to
stop on wet pavement measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tyre marked
C may have poor traction perform-
ance.
WARNING
The traction grade assigned to
this tyre is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.
Temperature -A, B & C
The temperature grades are A (the
highest), 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 tempera-
ture 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 higher levels of perform-
ance on the laboratory test wheel
than the minimum required by law.
WARNING
- Tyre
temperature
The temperature grade for this
tyre is established for a tyre 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 tyre fail-
ure. This can cause loss of vehi-
cle control and serious injury or
death.
Maintenance
Low aspect ratio tyre (if equipped)
Low aspect ratio tyres, whose aspect
ratio is lower than 50, are provided
for sporty looks.
Because the low aspect ratio tyres
are optimized for handling and brak-
ing, it may be more uncomfortable to
ride in and there is more noise com-
pare with normal tyres.
CAUTION
Because the sidewall of the low
aspect ratio tyre is shorter than
the normal, the wheel and tyre
of the low aspect ratio tyre is
easier to be damaged. So, follow
the instructions below.
- When driving on a rough road
or off road, drive cautiously
because tyres and wheels may
be damaged. And after driving,
inspect tyres and wheels.
- When passing over a pothole,
speed bump, manhole, or kerb
stone, drive slowly so that the
tyres and wheels are not dam-
aged.
