6. Use and maintenance
Tread wear indicator
The pattern
①
is used to indicate the wear of
the outer circular pattern of the tire. If the outer
circular of the tire is worn to the pattern, the
tire can no longer be used safely and must be
replaced immediately.
The “tread wear indicator”
②
is 1.6 mm in
height. If the tread pattern is worn to the
surface of the wear indicator, the tire can no
longer be used safely and must be replaced
immediately.
Wheel balance
The wheels of the new vehicle are balanced,
but during operation, the wheels may be
unbalanced due to various reasons, 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, each wheel must be rebalanced
after installation of a new tire or after tire repair.
Wheel misalignment
Inaccurate wheel alignment will cause uneven
and excessive tire wear and affect the driving
safety. If you find any uneven and excessive
tire wear, please go to GAC Motor authorized
shop to check the wheel alignment in time.
6.8 Tire chain
When driving in harsh environments such as
snow or icy roads in winter, it can increase the
degree of tire wear or cause other failures. To
reduce failures in winter, the following opinions
must be followed:
-
When driving the vehicle in deep snow,
it is necessary to install tire chains on
the tires. If snow chains are installed,
the equivalent of the size and type
corresponding to the tire specifications on
the vehicle must be selected. Failure to do
so will adversely affect the performance
and safety of the vehicle. Moreover,
full-load driving, speeding, emergency
acceleration, emergency braking,
emergency turning and other operations
are potentially very dangerous.
-
During deceleration, make full use of
the engine braking function. Emergency
braking on roads with snow or ice will
cause the vehicle to drift and slip. Keep
a proper safety distance from the vehicle
ahead and depress the brake pedal
slightly. It should be noted that the tire
chains installed on tires can provide some
friction, but can not prevent sideslip.
