Tire
■
For safe driving of the car, the type and size of the tires must be appropriate for your
car and the tires should have good tire treads and be under standard pressure.
■
The following section describes in detail the inspection methods of tire pressure, tire
damage and wear, and tire replacement.
Warning
●
Excessive tire wear, insufficient tire pressure or excessive tire pressure may cause
an accident with personal injury or even death.
●
Please follow the following instructions for tire inflation and maintenance.
Tire inflation
■
Maintain the tires under normal pressure to provide the best combination of
maneuverability, service life of the tires and driving comfort.
■
The use of under-inflated tires may cause uneven tire wear and can affect handling
and fuel consumption, and even cause air leakage due to overheating.
■
The use of over-inflated tires may reduce the driving comfort, and damage the tires
due to uneven road surface; in severe cases, it may cause a risk of deflated tire,
resulting in a significant accident.
■
It is recommended to check the tires every day. If it is found that one tire pressure is
too low, must measure the pressure with a tire pressure gauge immediately. Must
measure the tire pressure with the tire pressure gauge at least once every month;
even if the tires are in good conditions, the tire pressure may be reduced by 7~15kPa
(0.07~0.15kgf/cm
2
) every month.
■
The tire pressure should be measured when the tire is under cold status. It means that
the tire pressure should be measured after at least three hours from parking. If the car
must be driven before measuring the tire pressure, the driving distance does not
exceed 1.6km, which still be considered as the tires are under cold status.
■
If the tire pressure is checked under hot status (after driving for several kilometers),
the pressure reading may be 30~40kPa (0.3~0.4kgf/cm
2
) higher than the readings
under the cold status, which is normal. Do not deflate the tire to the specified pressure
reading under cold status; otherwise, it may cause that the tire pressure is insufficient.
■
Check the tire pressure with your tire pressure gauge each time.
