6. In-service maintenance
Service life of tires
Service life of tires depends on tire pressure,
driving style and tire assembly conditions.
If the front tires are worn more serious than the
rear tires, it is recommended to perform tire
rotation for the front and rear wheels as shown,
so as to make the service life of all tires about
the same.
Tread wear indicator
The tread wear indicator (arrow A) is 1.6 mm
high. If the tread pattern wears to the marked
surface, the tire can no longer be used safely
and must be replaced immediately.
The mark (arrow B) is used to indicate the
wear condition of the tire outer circle pattern.
If the tire outer circle pattern wears to the
condition as shown, the tire can no longer be
used safely and must be replaced immediately.
Wheel balance
The wheels of the new vehicle are already
balanced. Due to various reasons, the wheels
may go unbalanced during operation, which
can be manifested by the vibration of the
steering mechanism.
Because unbalanced wheels can cause
excessive wear on the steering system, wheel
suspension mechanism and tires, the wheels
shall be rebalanced.
In addition, wheels must be rebalanced after
installation of a new tire or tire repair for any
wheel.
Wheel misalignment
Wheel misalignment will cause uneven and
excessive wear of the tires, affecting driving
safety. If uneven and excessive wear of the
tires is found, please go to the GAC Motor
authorized shop to check the wheel alignment
as soon as possible.
