Tyres Used for Long Term
Tyres are made of rubber whose property changes gradually by aging as time goes on
(even when it is stored fitted on the rim like a spare tyre). Tyres must receive an aging
check after being used for up to 5 to 7 years if they are to be used continuously.
SERVICE AND MAINTENANCE
Tread Depth and Abnormal Wear
Using worn-out tyres is dangerous because
they are punctured or burst more easily
while you are driving than newer tyres
in good condition. Check all tyres to see
if tread wear indicators appear and also
check the tread depth on the entire tyre
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.
Tread depth (Standard value)
1.6 mm (0.063 in) or more
CAUTION
• Tyres with excessively shallow tread
grooves will increase the chance of
skidding and, when driving at high
speeds, hydroplaning.
• 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.
