A new tire is required if one of the
following conditions occurs:
• You can see a cord or fabric be exposed
through the tire rubber.
• Tread or sidewall is broken, cut or
cracked, and it is deep enough to see
the cord or fabric.
• The tire is bulging or delaminated. The
tire is punctured, cut or otherwise
damaged, and cannot be completely
repaired due to the damage area or
location.
The quality of rubber in tires will
deteriorate over time, even if these tires
have never been used. There are many
conditions that affect the rate of aging,
including temperature, load condition, and
inflation pressure maintenance. If the tire
is not properly maintained, it will usually
wear out before it deteriorates due to
aging. If you are not sure when you need to
replace the old tire with a new one, please
consult the tire manufacturer for more
information.
Please dispose of used tires in
accordance with relevant
environmental protection laws.
Buy new tires
When purchasing new tires, make sure
that their dimensions, load range, rated
speed and structure type are the same as
those of the genuine ones. In this way, the
performance of the vehicle will be as good
and as safe as before under normal use
after tire replacement. It is recommended
to replace the tires together. This is
because the uniform tread depth on all
tires will help to maintain the performance
of the vehicle most similar to that when the
tires are brand-new. If the four tires are
not replaced together, it may affect the
braking and maneuverability performance
of the vehicle. Refer to the "Tire Inspection
and Rotation" section in this chapter for
information on proper tire rotation.
Mixing tires will cause the vehicle to
get out of control while driving. If you
mix tires of different sizes or types
(radial tires or bias belted tires), the
vehicle may crash due to poor
maneuverability. Using tires of
different sizes or types may also
damage the vehicle. Tires of the
correct size and type should be used
on all wheels.
If diagonal ply tires are used on the
vehicle, the rim flange will crack after
a certain mileage. Tires or wheels will
suddenly get out of control and
cause a crash. Therefore, only radial
tires can be used on your vehicle.
Tires and Wheels of Different
Sizes
If you use wheels or tires with different
sizes from the original ones, it may affect
the performance of your vehicle, including
braking, driving and maneuverability,
stability, and rollover resistance, etc.
In addition, if your vehicle is equipped with
electronic systems, such as anti-lock
braking, these systems will also be
affected.
If you choose tires with specifications
