Sidewall surface
CAUTION
• Tyres with excessively shallow tread grooves will increase the chance of
skidding and, when driving at high speeds, hydroplaning.
NOTE
• Hydroplaning occurs when a vehicle is running at high speeds on a wet road
and a layer of water forms between the road surface and tyres causing the tyres
to float on it. Hydroplaning prevents the driver from steering correctly and from
slowing down the vehicle with the brake pedal.

SERVICE AND MAINTENANCE
Cracks and Other Damage
Gap between inner
Check the tread and sidewall surfaces
and outer tires
of each tyre for cracks or other damage.
Especially check the tread for nails or
other metal pieces embedded in grooves
and also the gap between the inner and
outer tyres of a dual-tyre wheel for pebbles
lodged in it.

Tread Depth and Abnormal Wear
Using worn-out tyres is dangerous because
they might have an increased chance
of getting punctured or bursting while
driving. Check all tyres to see if tread wear
indicators appear on their treads and also
check their entyre tread for its depth with a
depth gauge to make sure that the grooves
are deeper than the specified depth.
A tyre with tread wear indicators appearing
must be changed. Also, check the tyres for
uneven or otherwise abnormal wear.
ADVICE
• When checking tyres, pay special
attention to: low air pressure;
pebbles or nails in tread grooves;
cracks or other damage on tyre
surfaces; uneven wear; and pebbles
lodged in the gap between tyres of
dual-wheel tyres.
