Tire wear indicator
- Arrow A - the tire outer circle pattern is
used to indicate the wear condition of the
tire tread 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.
- Arrow B - the raised tread wear indicator
mark
②
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.
6.8 Tire chain
In winter, driving in harsh environments such
as snowy or icy roads can increase the degree
of tire wear or cause other failures. To reduce
failures in winter, the following opinions must
be followed:
- When driving in deep snow, it is
necessary to install tire chains on
the tires. If so, be sure to choose an
equivalent product whose size and type

vehicle. Failure to do this will adversely
affect the performance and safety of the
vehicle. Moreover, operations such as
full-load driving, speeding, emergency
acceleration, emergency braking, and
emergency turning are potentially
dangerous.
- During deceleration, make full use of
the engine braking function. Emergency
braking on snowy or icy roads will cause
the vehicle to flick and slip. Maintain an
appropriate safety distance from the
vehicle in front, step on the brake pedal
slightly, and pay attention to that installing
tire chains on the tires can increase
certain friction force, but can not prevent
side slipping.
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 or the vehicle is obviously
running sideways, please go to the GAC Motor
authorized shop to check the wheel alignment
as soon as possible.
