The balance of the wheels is crucial for the driving stability and safety of the car, and it is divided into two types: static balance and dynamic balance. Here are a few situations where a wheel is required to be static and dynamically balanced:
It is necessary to do the case of static balancing of the wheels
Static balance mainly refers to the mass equilibrium on the circumference of the tire. Wheel balancing may be required in the following cases:
There are obvious uneven mass distribution of wheels when they are static, such as uneven tire wear, improper tire installation, etc.
When it is necessary to do wheel dynamic balancing
Dynamic balancing refers to the mass balance of the tire along the axis, and the following are the specific situations in which the wheel dynamic balancing needs to be done:
The vehicle leaves the factory and is regularly maintained
When the vehicle leaves the factory, in order to ensure driving stability, the dynamic balance test will be carried out.
In daily use, it is recommended that the dynamic balance of the new car be checked once after driving for about 3 months, and then every six months or after driving more than 10,000 kilometers.
Tire replacement and repair
When replacing new tires, it is necessary to remove all the original balance weights on the rim and rebalance the wheel.
After repairing tires (e.g., repairing tires, installing tire pressure monitors, etc.), the balance of the tires may be disrupted, so dynamic balancing is also required.
Reassembly of tires and wheels
If the tire and the hub are separated and reassembled, such as after tire replacement, wheel repair, etc., dynamic balancing is also required.
Vehicle Accidents & Injuries
Balancing is required in the event of a vehicle collision or a wheel impact that can cause tire deformation, wheel hub damage, or loss of balance weights.
Damaged or deformed rims can also affect the balance of the wheels, and dynamic balancing is required to determine if the rims need to be replaced.
The vehicle is driving abnormally
When the vehicle is driving at high speed, if there are abnormal phenomena such as steering wheel shake, body shake, direction deviation, abnormal wheel noise, and vehicle head swing, it may be caused by wheel imbalance, and dynamic balancing is required at this time.
Tire eccentricity
Single-sided or one-sided bias wear of the tire can also be caused by wheel imbalance and requires dynamic balancing.
In short, the static balance and dynamic balance of the wheels are important measures to ensure the stability and safety of the car. In the event of the above situation, the wheel balance should be detected and adjusted in time to ensure the driving performance of the car.
